Uncovering the Source of Unpleasant Stones: Examining Kidney Stones and their Causes

Key Takeaways:

  1. Genetics, diet, medications, and other risk factors can all contribute to the formation of kidney stones.
  2. Adequate hydration, physical activity, and getting enough calcium can help reduce the risk of kidney stone formation.
  3. St Pete Urology has specialized experience in the prevention, diagnosis, and treatment of kidney stones.

 

Kidney stones are a common condition that can cause severe pain. They differ in size, shape, and composition and can develop in one or both kidneys. In some cases, they are so small they pass unnoticed with no attendant symptoms. In other cases, the stones are larger, and the symptoms can be quite severe. Identifying the source of the stones can lead to better treatments and even prevention for many individuals. Knowing the causes of kidney stones leads to a better understanding of their development and the steps that should be taken to prevent them.

Genetics

Genetics may also play a role in kidney stone formation. It appears that inheriting genes from family members may increase the risk of developing stones. Additionally, the risk of kidney stones may vary depending on sex. Men are more likely to develop stones than women.

Diet

Diet also plays a role in stone formation. There is an association between consuming too little dietary calcium and kidney stones. Additionally, foods with a high content of oxalate (such as spinach, chard, rhubarb, and other dark leafy greens) can increase the risk of stone formation.

Medications

Some medications can increase the risk of kidney stones, including certain antibiotics and diuretics. It is also important to pay attention to the potential for dangerous drug interactions with other medications and food.

Other Risk Factors

Dehydration is one of the main risk factors for developing kidney stones. Additionally, underlying medical conditions such as diabetes and gout can increase the risk of developing stones.

Prevention

Fortunately, there are ways to reduce the risk of kidney stone formation. Adequate hydration, including drinking enough fluids, is essential. Additionally, engaging in regular physical activity and getting an appropriate amount of calcium consumption can help prevent the development of stones. Certain medications and supplements can also help reduce the risk.

Conclusion

Kidney stones are common and can be incredibly painful when they reach a certain size. Fortunately, understanding the source of stones and the factors that contribute to their formation can help with diagnosis, treatment and even prevention. Genetics, diet, medications and other risk factors can all influence the development of kidney stones. Therefore, making lifestyle changes and being mindful of risk factors can help reduce the formation of stones.

Is blood in the urine serious?

Blood in the urine, medically referred to as hematuria, should always be taken seriously because any blood in urine can indicate an elevated risk of severe health problems even if it occurs once. 

For instance, it can indicate an infection, kidney disease, cancer or a rare blood disorder.  So if you see blood in your urine, no matter how minor, you should never ignore it and immediately see a urologist. 

What are the different types of hematuria?

Blood in the urine can occur in two ways. It can present itself as gross hematuria or as microscopic hematuria. Gross hematuria means that your urine has significant elevation of blood and its color appears red or pink. Or your urine has spots of visible blood.

Microscopic hematuria means the amount of blood in your urine is so small that it can’t be seen with the naked eye. So your urine is not red or pink in color but a lab test can detect the blood or blood cells in the urine can be detected when a sample of the urine is examined under a microscope.

What are the causes of hematuria?

  1. Urinary tract infection

A bacterial infection somewhere in your urinary tract, kidneys or bladder can cause hematuria. An infection occurs when bacteria enters your urethra and moves and multiplies in the bladder or kidneys. The infection may result in pain, frequent urination, and bleeding that can eventually lead to gross or microscopic hematuria.

  1. Stones

Stones are crystals that form from minerals and other substances in your urine, especially when they are at high concentration. The stones form in the bladder or kidney and may lead to pain and bleeding as the stones pass through the urinary tract. Larger stones typically block the urinary tract and cause significant pain and hematuria.

  1. An enlarged prostate

For men who are middle-aged and older, the prostate gland tends to get bigger, compress the urethra, make it difficult to urinate, and may result in urinary tract infection (UTI). When an enlarged prostate causes UTI, blood in urine is often one of the symptoms of the infection.

  1. Kidney disease

When a kidney is inflamed, infected or damaged, bleeding may occur, resulting in blood in urine. Kidney disease can occur on its own or as part of another disease, like diabetes.  

For instance, in children aged 6-10 years, the kidney disease known as post-streptococcal glomerulonephritis, which tends to develop 1-2 weeks after untreated strep infection, usually causes hematuria. It is nowadays quite rare because antibiotics effectively treat strep infections.

  1. Cancer

Blood in urine can be due to bladder, prostate, or kidney cancer, typically as a symptom of advanced-stage tumor. Because blood in urine is rarely an early sign of cancer, you should see your doctor immediately to rule out the possibility of cancer.

  1. Medications and rare conditions

Hematuria can be caused by drugs like aspirin, penicillin, blood thinners (like heparin and warfarin), and cyclophosphamide (a drug used to treat certain cancers). Rare blood disorders like hemophilia, Alport syndrome, and sickle cell anemia also cause hematuria. 

Plus, you can have blood in your urine after strenuous exercise, a trauma to the kidneys, or if blood is coming from a different source, such as from bowel movement, the vagina in women, or the ejaculate in men.

When should you seek medical attention?

Blood in urine may be a sign of a grave underlying condition, so you should speak with your doctor as soon as possible. You must never ignore hematuria, even if only a small amount of blood occurs in the urine. 

Visit your doctor immediately if you see blood clots as you urinate or if you have hematuria along with nausea, vomiting, fever, chills, or pain in your abdomen, back or side. 

Also, speak with your doctor if you don’t see blood in urine but experience frequent pain, difficulty urinating, or have abdominal or kidney pain, as these could indicate microscopic hematuria.

During your visit, your doctor will ask you about when and the amount of blood you see during urination.  The physician will also want to know how frequently you urinate, any pain or blood clots in the urine, and any medications you’re taking. 

The doctor will then perform a physical exam, obtain a sample of your urine for analysis, and may order imaging tests, like CT scan or cystoscopy.

The treatment offered after the tests will depend on the underlying cause of the hematuria. For instance, if it is due to urinary tract infection, your doctor will prescribe antibiotics. 

For hematuria caused by an enlarged prostate, your doctor may prescribe 5-alpha reductase inhibitors, alpha blockers, or surgery.

What dissolves kidney stones fast?

You’re suddenly in an excruciating pain. You have a sharp, cramping pain in your back and side that comes in waves. And the overwhelming feeling moves to your lower abdomen or groin, and hurts badly.

Well, you probably have kidney stones. And you need to give it a quick fix. You can do that without medical intervention, especially if you can find something that will dissolve the stones fast.

Types of kidney stones

Generally, up to 80 percent of kidney stones are calcium stones—usually either calcium oxalate or calcium phosphate. These types of stones occur if you have too much calcium in your urine, though they could also form for other reasons.

Another type of stones, struvite stones, is related to chronic urinary tract infections, makes up 10 percent of all kidney stones and often forms when urine is alkaline. Uric acid stones make up 5-10 percent of kidney stones, and require acidic urine to form; while cystine stones that are less than 1 percent of all stones form when you have cysturia—too much cystine in urine.

Apple cider vinegar as kidney stones remedy

If you’re looking to dissolve kidney stones fast, you can rely on apple cider vinegar. Made from fermenting apples and endowed with phosphoric, citric and acetic acids, apple cider vinegar makes urine acidic and helps to dissolve most types of kidney stones quickly.

The acids in the apple cider vinegar react rapidly with compounds forming stones, especially calcium and struvite stones. As the reactions occur, the stones reduce in size and eventually dissolve.

Once the stones are dissolved or their size significantly reduced, they are easily flushed out in urine. Equally, as the stones break down, their obstruction of the urinary tract is reduced. Hence the pain caused by the stones is relieved.

Besides, apple cider vinegar reduces the risk of stone formation by dissolving minerals that may form stones. It also has an alkalizing effect that boosts the digestion process and increases the production of hydrochloric acid. The acid dissolves various minerals and helps prevent the formation of new kidney stones.

To prepare apple cider vinegar as remedy for kidney stones, mix two tablespoons of apple cider vinegar with 6-8 ounces of water and drink the mixture frequently throughout the day, but mostly before mealtime. You should not consume more than one 8-ounce glass of this mixture per day as excess apple cider vinegar can reduce potassium levels and cause osteoporosis.

Lemon juice remedy for kidney stones

Apart from apple cider vinegar, you can use lemon juice to dissolve kidney stones. Usually, a mixture of lemon juice with olive oil is preferred as the lemon juice provides citrate that breaks up or prevents calcium stones from forming while the olive oil helps to flush out the stones.

Mix a quarter of a cup of olive oil with equal amount of lemon juice and drink. Follow it with a glass of water. Repeat this in the afternoon, but making sure to drink plenty of water and plenty of lemon juice throughout the day.

Alternatively, you can just squeeze some lemon into your drinking water as often as you can. Unfortunately, this will require a great deal of lemon juice if it has to produce the effect you desire.

Other natural options that help with kidney stones include:

  1.     Celery juice
  2.     Pomegranate juice
  3.     Basil juice
  4.     Dandelion root juice
  5.     Horsetail juice
  6.     Wheatgrass juice

These juices help eliminate waste, enhance digestion, and increase urination. They are also packed with a lot of nutrients and can relieve inflammatory issues.

But as you go for the juices, also remember that drinking plenty of water is necessary. Drinking enough water prevents dehydration, dilutes urine, and hinders formation of kidney stones. Water also helps stones to pass through the urinary tract. As a rule, you should drink 6-8 ounces of water per day.

When should you see a urologist?

When kidney stones are too large and cause severe symptoms, visiting a urologist for treatment is the right option. Your doctor may prescribe medication such as tamsulosin (Flomax) to relax your ureter and make it easier for the stone to pass.

You may also be given pain and anti-nausea medicine to help you cope. Plus, your doctor may consider procedures such as extracorporeal shock wave lithotripsy (ESWL), ureteroscopy, percutaneous nephrolithotomy (PCNL), laparoscopy, and robotic surgery to help remove the stones.

You should see a urologist if your symptoms are becoming severe after using apple cider vinegar or lemon juice remedy for a few weeks. Indicators of worsening kidney stones include nausea, blood in urine, painful urination, severe pain in the lower back or abdomen, vomiting, fever, and chills. In fact, if you’re not able to pass the stone for six weeks then you should see your doctor to determine whether you need therapy.

At St Pete Urology, we see many patients with kidney stones on a regular basis and know exactly what to do in every situation. Our team of urologists has the skill, expertise, and experience to give effective treatments for the stones, particularly if you’re not able to pass the stones naturally.

Our range of treatments includes medication and procedures like lithotripsy (ESWL), ureteroscopy, percutaneous nephrolithotomy (PCNL), laparoscopy, and robotic surgery. Schedule your appointment with us if your symptoms have lasted more than six weeks. For more information on the diagnosis and treatment of urologic disorders, visit the site “St Pete Urology”.

What Foods Are Good For Kidneys?

Kidneys play a significant role in the overall health of the body. They filter out waste products from blood and send them out of the body as waste through urine. The kidneys also balance fluid and electrolyte levels in the body while making hormones that regulate the function of other organs of your body. But to keep your kidneys healthy, you need to watch what you eat and drink because some foods boost the performance of the kidneys while others stress, degrade and damage them.

What foods support healthy kidneys?

Kidney-friendly foods are those that enhance kidney function and protect them from damage. Generally, a good balance of quality protein, calories, vitamins, and minerals are great for the kidneys. Very high dietary levels of some mineral ions such as sodium, potassium, phosphorus and calcium may in the long run endanger your kidneys. Foods linked to heart problems and high blood pressure may put additional pressure on the kidneys.

For healthy kidneys, consider the following:

1. Stay Hydrated

Water helps to flush out toxins from the body. In fact, the body relies on water to assist transporting toxic wastes into the bloodstream, then to the kidneys where they are filtered and removed through urine. This process helps reduce the risk of bacterial infection, kidney stones, and kidney disease, which is why water is crucial for the critical salt-fluid balance in the body.

Ideally, you should drink 6-8 glasses of water per day, but of course you can drink more if you are active during the day. In addition to the many other benefits of staying hydrated, drinking water when thirsty helps to support your kidneys.

2. Apples and mushrooms

Apples are rich in fiber. One of the fibers, called pectin, helps to reduce various risk factors for kidney disease, such as high blood sugar and cholesterol levels. Apples also have anti-inflammatory constituents, prevent constipation, protect against heart disease, and lower the risk of cancer. You might also consider eating mushrooms for their high levels of vitamin D, which boosts kidney function.

3. Sweet potatoes

Sweet potatoes have a robust fiber profile. They break down very slowly in the body which helps to support low insulin levels. Sweet potatoes also have a healthy amount of vitamins and minerals, such as potassium which helps to balance sodium levels in the body and reduce the effect of sodium on the kidneys. However, since they contain high levels of potassium, sweet potatoes are not ideal for those with chronic kidney disease (CKD).

4. Berries

Dark berries, such as strawberries, raspberries and blueberries are a great source of nutrients and antioxidants and for most people protective for the kidneys.

5. Dark leafy vegetables

Leafy vegetables such as kale, spinach and chard contain a wide variety of vitamins, fibers, and minerals that support kidney function. While they do supply a number of protective compounds, dark leafy vegetables are highly rich in potassium and therefore less suitable for those with chronic kidney disease (CKD), restricted diet, or patients on dialysis.

6. Kale and cauliflowers

Kale is a terrific source of vitamins A and C which reduce inflammation, boost the immune system and protect the kidneys. Kale is also lower in potassium compared to other greens, and contains lots of iron. Like kale, cauliflower is rich in vitamin C and also has plenty of fiber and folate that are crucial for kidney function. Likewise, cauliflower contains compounds that improve the liver’s ability to neutralize toxic substances and reduce the stress on the kidneys.

7. Fatty fish and egg whites

Tuna, salmon and other cold-water, fatty fish have high omega-3 fatty acids. The omega-3 fatty acids in these fish are heart protective and also healthy for the kidneys. Since high blood pressure is a risk factor for kidney disease, fatty fish is a great way to improve your cholesterol profile and protect your kidneys.

Foods to avoid include:

1. High salt

Elevated salt levels raise blood pressure making the heart and kidneys work extremely hard. You can control your salt intake by cooking at home and avoiding most fast foods which are sky high in sodium.

You can also try substituting new spices and herbs in place of salt and by avoiding packaged and pre-cooked foods, such as soups, frozen dinners, and boxed meals that usually have extra salt. Similarly, you should avoid table salt and high-sodium seasonings like soy sauce, garlic salt and sea salt.

2. Foods rich in potassium

While potassium helps your nerves and muscles to work properly, too much of it can lead to serious heart problems and eventually to kidney issues. Potassium is found in most fruits and vegetables, such as bananas, oranges, avocadoes, raw carrots, cooked broccoli, potatoes, greens, tomatoes, and melons.

Instead of these high potassium foods, try alternatives such as apples, cranberries, blueberries, raspberries, and strawberries. Other good options are pineapples, peaches, plums, asparagus, cabbage, cucumber, and beans (green and white).

3. Limit phosphorus and calcium

Phosphorus and calcium are great minerals for keeping your bones healthy and strong. But high levels of phosphorus may increase the risk of long-term kidney disease. Since most foods that contain phosphorus are also equally rich in calcium, the body’s levels of the two minerals can be controlled by similar mechanisms.

If your doctor suggests limiting phosphorus, avoid foods such as red meat, dairy products, nuts, fish, most grains, and legumes. Consider replacing these foods with healthy foods that are lower in phosphorus, such as fresh fruits and veggies, rice, corn and fish.

At St Pete Urology, we encourage our patients to take care of their kidneys through healthy behaviors—exercise, drinking plenty of water and eating a balanced diet. We also perform surgeries and treat urination problems such as incontinence, tumors, cysts, growth and stones of the urinary system, as well as problems of the male reproductive system. For more information on kidney disorders and their treatment, visit the St Pete Urology website.

The 5 Best Ways to Prevent Kidney Stones

When certain chemicals become concentrated in urine, they coalesce into crystals. The crystals then grow into larger mineral deposits called kidney stones. Most kidney stones form when calcium combines with either phosphorous or oxalate, but some form from uric acid, a byproduct of protein metabolism. Once formed, kidney stones can make their way through the urinary tract and pass from the body without problems. At other times, a stone will get stuck somewhere, block urine flow and cause intense pain.

Growing concern

Kidney stones are a rising concern. In fact, one in ten people will have kidney stones during their lifetime. Currently, up to 12% of Americans have stones and those who have had one are 50% more likely to get another within the next 10 years if no preventive measures are taken.

The passing of kidney stones is often characterized by agonizing and intolerable pain that comes in waves as the stones move through the urinary tract and out of the body. The pain may occur on one side of your back or abdomen, or it may radiate to your groin and belly area. While the severity of the pain does not necessarily relate to the size of the stone, larger stones tend to be more painful than smaller ones.

What are the 5 best ways to prevent kidney stones?

1. Drink plenty of fluids.

When you pass a lot of urine every day, you have a lower risk of developing kidney stones. The more you urinate, the lower the chance of stone-causing minerals settling and combining in your kidneys and urinary tract. Drink plenty of water to ensure you urinate up to 2 liters of urine daily. You will need roughly eight 8-ounce cups of water to achieve that. Orange juice and lemonade are also good because the citrate they contain helps prevent stone formation.

If have a history of cystine stones, engage in heavy exercise or just sweat a lot, you should drink even more water. Demanding workouts increase water loss through sweating and reduce urine output, so keep your body hydrated during and after exercise. You can tell if you are properly hydrated by the color of your urine. A clear to pale yellow urine means proper hydration while a dark color indicates a need for more fluids.

2. Increase your calcium intake.

Calcium oxalate stones are the most common kidney stones. But that does not mean you should avoid calcium-rich foods—actually the opposite is true. A low-calcium diet increases the risk of stones and osteoporosis. A calcium deficiency allows oxalate levels in urine to rise, triggering the formation of stones.

A good approach is to enhance your daily intake of calcium according your age. For instance, if you are a man 50 years or older, you need 1,000 milligrams (mg) of calcium per day, together with 800 to 1,000 international units (IU) of vitamin D to help with calcium absorption.

Calcium-rich foods include cheese, milk, and yogurt. Avoid calcium supplements as they may increase your risk of kidney stones; however, you can reduce that risk by taking supplements with your meals. It is always a good idea to speak with your doctor when considering supplements and dietary changes.

3. Eat fewer oxalate-rich foods.

Oxalate is a natural compound found in some foods. Since it binds with calcium in urine to form kidney stones, reducing oxalate-rich foods helps prevent stones from forming. Examples of foods rich in oxalate are chocolate, spinach, coffee, peanuts, beets, rhubarb, sweet potatoes, beets and wheat bran. Colas should also be avoided because they are rich in phosphate.

If you have suffered from kidney stones, your doctor may recommend you avoid these foods or consume them in smaller quantities. However, you can also eat oxalate-rich foods alongside calcium-rich foods as an alternative to avoiding them. Calcium and oxalate can bind together to actually reduce the risk of kidney stones.

4. Reduce your sodium intake.

When your diet is high in sodium, the amount of calcium in your urine increases. Sodium prevents calcium re-absorption from urine to blood, which in turn leads to high calcium in urine that may cause kidney stones. Reducing sodium intake lowers the amount of calcium in your urine.

The recommended daily limit of total sodium intake is 2,300 mg. But if sodium has contributed to your kidney stones in the past, you should reduce intake to 1,500 mg per day. Your doctor may advise that lowering sodium benefits your blood pressure as well. It is easier to lower sodium intake by avoiding foods such as:

  • Processed foods, like crackers and chips
  • Canned vegetables
  • Canned soups
  • Condiments
  • Lunch meat
  • Foods containing sodium nitrate, monosodium glutamate, or sodium bicarbonate (baking soda)

5. Limit intake of animal proteins.

Animal proteins not only raise the amount of uric acid in your body, they also increase body acid levels. Increased urine acidity promotes the formation of both uric acid and calcium oxalate stones.

How does the kidney filter blood?

How does the kidney filter blood?Many people do not realize how vital their kidneys are to their overall health until an issue arises and they need to seek medical care. Knowing what your kidneys do and how they function can go a long way toward maintaining good health before a problem occurs or understanding the treatment process once you are under a urologist’s supervision.

What Do My Kidneys Do?

Your kidneys are basically your body’s filtration system. Every minute, approximately half a cup of blood flows through them. As the blood flows through, waste products are removed, as is excess water; the levels of minerals and salt are also adjusted if need be. Although around 150 quarts of blood are filtered by your kidneys every day as it continually cycles through your body, only about 1-2 quarts of urine are produced from the waste products and excess water. The urine then flows to the bladder through a tube called the ureter.

How Do My Kidneys Work?

Inside each kidney, there are about a million tiny filtration units called nephrons. The nephrons are made up of a filter called a glomerulus and a tube called a tubule. Blood flows through the glomerulus, where waste and excess water or minerals are filtered out. The tubule then sends the filtered substances to collect in the kidneys before flowing through the ureter to the bladder, while the newly-filtered blood is returned to the rest of the body. There are so many nephrons in your kidneys that even if more than half of them are no longer working, you may not notice any issues or symptoms.

What Happens If Something Goes Wrong?

Many things can occur to interrupt the function of your kidneys. Warning signs of kidney disease include an increased need to urinate, especially at night, blood in the urine, foamy urine, cramping muscles and swollen ankles and feet. These are all signs that something could be wrong with the filtration system in your kidneys, causing issues with fluid and electrolyte levels in your body.

Another common problem is kidney stones. When there is a buildup of certain waste products in the kidneys and not enough fluid to flush them out, these waste products can crystallize and form stones that cause extreme pain as they leave the body. If you suspect you are dealing with kidney stones, kidney disease, or other problems with your urinary system, it’s important to talk to a doctor right away, like the urologists at St Pete Urology, who will be able to diagnose any issues and help you and your kidneys return to normal healthy function as soon as possible.

Why Do I Keep Getting UTIs?

Urinary tract infections (UTIs) are caused by bacteria or E.coli in the organs of the urinary tract — the kidneys, ureters, urethra and the bladder. Most UTIs affect the urethra and the bladder alone. While UTIs affect both men and women, the rate of prevalence and recurrence is higher among women, with about 50 percent of all women expected to contract the infection at least once in their life time and 20-30 percent expected to suffer a recurrence.
The high prevalence of UTIs among women is attributed to the fact that the urethra in women is shorter than in men. The urethra in women is placed closer to both the anus and the vagina. Bacteria from the anus and those that enter the vagina during intercourse have only to travel the short length of the urethra to reach the bladder. Besides gender, the other risk factor for UTIs for both genders is advanced age.

Causes of recurrence

A case of UTI is said to be recurrent or persistent if a patient contracts at least four infections in a period of one year. Recurrence of UTIs occurs almost solely among women. Other than the positioning of the urethra in their bodies, this recurrence may be caused by factors such as:

1. Failure to complete a dose of antibiotics. Once the benefits of taking the prescribed antibiotics start to manifest, some patients stop taking the drug because they think the UTI has cleared. Urologists discourage this behavior and advise patients to complete the dose to reduce the chances of any left over bacteria causing a recurrence.

2. Sex is a risk factor. Sexually active women face a higher risk of contracting a UTI because of the transmission of bacteria during intercourse. The risk can be reduced by urinating before and after sex or by taking an antibiotic before or after sex if a doctor prescribes it.

3. Post-menopausal hormonal changes. Menopause lowers estrogen levels in women causing an imbalance in the bacteria in the vagina. This makes women susceptible to infection and recurrence. A urologist can prescribe a vaginal estrogen cream to remedy the problem.

Women are genetically predisposed to contracting UTIs, both because of their anatomy and hormonal changes as they get older. But UTIs in women are highly treatable and are only rarely very serious. If anyone experiences persistent infections, she should seek the advice of expert urologists, such as those found in St. Pete Urology. The experienced specialists at St. Pete Urology can offer consultation, diagnosis and treatment for any UTI problems. For more information, visit the “St Pete Urology” site.

What Can You Do To Reduce The Risk of Having Kidney Stones

Kidney stones are hard, crystallized minerals that form in the kidneys that may spread to other organs in the urinary tract such as the bladder and the ureter. They form when urine becomes so concentrated with minerals that the minerals crystallize and harden. Often stones are formed from a fusion of calcium and oxalate or phosphorus. Symptoms of kidney stones include trouble passing urine, excruciating pain when passing urine, pain in the groin, below the ribs and in the abdomen, blood in the urine and frequent urination. While reports indicate that the prevalence of kidney stones has grown in modern times, the condition still remains a preventable one.

Ways of preventing Kidney Stones

1. Cut down on sodium intake
A heavy sodium intake causes a proportionate increase in the amount of calcium in urine, creating a good chance of kidney stone formation. Processed and canned foods are known to contain high amounts of sodium. It is advisable to reduce one’s consumption of such foods.

2. Staying hydrated
Drinking enough water and other fluids is one of the best and easiest ways to prevent kidney stones. Water dilutes urine, making it less concentrated. A shortage of fluid in the body translates into just a little concentrated urine. Urine salts are more likely to crystallize and form stones because there is insufficient water to dissolve them.

3. Consumption of foods rich in calcium
Even if most stones have aspects of calcium, calcium rich foods such as milk and cheese prevent the likelihood of kidney stone recurrence. This is because the levels of oxalate, which is a stone forming mineral, increase with decreasing levels of calcium. Calcium should be maintained at a good level.

4. Cut down on the intake of animal proteins and fructose
Organ meats, red meat, seafood and poultry contain a compound known as purine which contributes to the formation of kidney stones, specifically uric acid stones. The same goes for foods with high fructose, with corn syrup specifically being one to avoid. Managing the intake of these foods should go a long way in preventing stones from forming.

In addition to watching one’s diet, medical professionals advise that people should obtain a good amount of exercise to prevent weight related disorders such as obesity.

Kidney stones are very painful and, in this instance, there is no question that prevention is much better than cure. If you discover that you have kidney stones, you should seek medical attention immediately. For those interested in prevention only, reading up on the subject can offer practical ways to avoid having kidney stones. The staff of specialists at St. Pete Urology also are able to help with diagnosis, prevention and treatment of kidney stones. For more information, visit the St Pete Urology website.

How can I prevent recurrent kidney stones

Kidney stones occur when tiny crystals form and stick together as solid masses in urine. Often, due to increased concentration of various chemicals in urine, crystals form and then grow into larger masses that move through the urinary tract. As they move, the stones may get stuck somewhere along the tract and block urine flow, causing pain. Most kidney stones are a combination of calcium with either oxalate or phosphate, but stones also may form when uric acid levels increase in urine as a result of protein metabolism.

Preventing kidney stone recurrence

For many people who have had a kidney stone, it is not a one-time thing. In fact, in about 50 percent of those who have had a stone, another one will appear within 7 years if no preventive measures are in place. At St Pete Urology, we ensure that our patients take the necessary steps to prevent a recurrence. That is why, after treatment, we conduct a special urine test on our patients to find out why the stone formed in the first place. Using the results of the test, we guide our patients on how best they can avoid a recurrence.

Some of the measures we recommend to avert kidney stone recurrence include:

1. Drinking enough water

Water dilutes urine, reduces the concentration of substances in it and prevents kidney stones. To prevent recurrent kidney stones, you should endeavor to drink enough fluid to pass at least 2 liters of urine per day. Increased fluid intake that is distributed throughout the day decreases kidney stone recurrence by about 50 percent and with virtually no adverse effects.

For better results, you may add orange juice or lemonade to the water so there is increased citrate in the fluid to block stone formation. Medication such as allopurinol, citrate or a thiazide diuretic can be taken with the fluid to minimize the chance of kidney stone recurrence. However, if you are already drinking that much fluid before your kidney stones, you should not increase your fluid intake.

2. Making dietary changes

Once you are treated for kidney stones, we will recommend that you reduce your intake of eggs, seafood, poultry, red meat and other animal protein. These foods increase uric acid levels while also reducing citrate levels in the body, which can trigger a recurrence of kidney stones. That is why after treatment for kidney stones, we recommend that you should cut down your daily meat portions to a size no larger than a pack of playing cards. Likewise, you should avoid foods such as chocolate, strawberries, wheat bran, beets, spinach, tea, rhubarb and most nuts that contain oxalate or the phosphate containing colas that may trigger kidney stone recurrence.

3. Increasing calcium intake

Oxalate levels may rise and trigger kidney stones if the level of calcium in the diet is low. So after treatment, it is important to ensure that you increase your calcium intake to match your age. For example, if you are a man 50 and older, you should get 1,000 milligrams of calcium every day, together with 800-1000 IU (international units) of vitamin-D to ensure your body absorbs the calcium properly. With increased dietary calcium, you can prevent a recurrence of kidney stones.

4. Reduced sodium intake

Kidney stones may recur if there is a lot of sodium in your diet because increased sodium leads to high concentration of calcium in urine. So after treatment for kidney stones, we usually recommend that you lower the amount of sodium in your diet, limiting your total daily sodium to 2,300 mg. But if sodium was responsible for your previous kidney stones, then we recommend that you should take at most 1,500 mg of sodium per day. Such a low level of sodium also will be good for your heart and your blood pressure.

Those are some of our most common recommendations for averting kidney stone recurrence. As you might have noticed, they are not complicated things to do, but they do require some commitment. For more information on prevention and treatment of kidney stones, visit the “St Pete Urology” site.

3 Effective Minimally Invasive Surgical Treatment For Kidney Stones

Over the last 15 years, kidney stone prevalence has doubled in United States. Today, roughly 1-in-10 Americans will have a kidney stone attack at some point during their lifetime. When they occur, kidney stones can cause agonizing and unbearable pain in the back and side, and may sometimes trigger nausea and vomiting. You can pass a stone by drinking plenty of water — taking pain medications to control the discomfort as you wait for the stone to pass. But if you have a large stone or one that’s causing complications, then a more extensive treatment may be necessary to remove the stone.

Minimally-invasive surgical treatments

At St Pete Urology, we offer surgical treatment for kidney stones, focusing on minimally-invasive procedures even for the largest stones. Most operations for smaller stones can be done as same-day surgeries, giving patients greater flexibility and a faster return to their work and other routine activities. For larger stones, the planning and execution of the procedures may take a little more time, but with the use of small incisions only large enough to allow insertion of thin tubes, fiber-optic lights, cameras and other tiny surgical tools, we are able to ensure significantly less pain, less scarring, shorter hospital stay, faster recovery and increased accuracy than with traditional open surgery for the stones.

There are three main minimally-invasive techniques for removal of kidney stones. The least invasive being extracorporeal shockwave lithotripsy, followed by ureteroscopy then lastly percutaneous nephrolithotomy. The choice of a surgical technique depends on multiple factors, including the type of stone, size and location, medications taken by the patient, other medical problems the patient may have, and patient preferences.

Extracorporeal Shockwave Lithotripsy (ESWL)

This is the most popular option for treating small and medium-sized stones. Performed in an outpatient setting with the patient placed under general anesthesia, ESWL is the least invasive and takes 20-30 minutes to be completed. During the surgical procedure, intense sound waves are focused on the kidney stone, shattering the stone with minimal effect on surrounding tissue. Smaller pieces of stones that are produced get washed out of the urinary system with the normal flow of urine, often with slight or no discomfort. ESWL is a highly effective treatment for most stones that form in the kidney or ureter.

Advantages of ESWL include:

  1. It’s an outpatient procedure so patients return home after a few hours.
  2. It offers excellent success rate with most small-sized and medium-sized stones.
  3. It doesn’t require incisions or invasive techniques.
  4. It has minimal postoperative discomfort.
  5. It has a fast and easy scheduling.

Limitations of ESWL include:

  1. It’s ineffective for stones that are very hard or resistant to breakage by shockwaves.
  2. It’s not appropriate for stones that are invisible on X-ray such as uric acid, monohydrate and cystine stones.
  3. It’s not ideal for larger stones or those located in the lower part of the urinary tract.
  4. It’s not appropriate for patients with certain conditions or using certain medications, such as pregnant women or patients on blood thinning medications.

Ureteroscopy

Ureteroscopy is another surgical procedure often used to treat small and medium-sized stones. The advantage it offers over ESWL is that it can treat kidney stones occurring in any part of the urinary tract. It’s a same-day procedure done after the patient is placed under general anesthesia. The procedure involves passing a small scope via the urinary opening and into the bladder then into the ureter. Once the stone is reached, it is targeted with laser so that it’s broken down into smaller pieces that are extracted out of the system or into pieces of dust left to wash out with normal urine.

Ureteroscopy is a little bit more invasive than ESWL, but it’s preferred in situations where kidney stones are too hard to respond to ESWL, or for stones that are invisible on X-ray. Ureteroscopy is also a better choice than ESWL when stones are located in the lower portion of the urinary tract, especially the region near the bladder. After the procedure, a small tube — a stent — is temporarily placed into the urinary system to help drain the kidney. The stent is totally internal, and is usually removed 3-10 days after the procedure. Stent removal is a quick and easy process done in the doctor’s office and without anesthesia.

Advantages of ureteroscopy are:

  1. Great results for small-sized and medium-sized stones.
  2. It’s an outpatient procedure.
  3. No incisions are necessary.
  4. Fast and easy scheduling.
  5. Done without stopping the use of blood-thinning medications.
  6. Effective for stones that are resistant to ESWL.

Limitations of ureteroscopy are:

  1. It’s not effective for very large stones.
  2. In some rare instances, scopes may not reach the stones.
  3. Many patients find the stents placed after the procedure a source of unease and discomfort.

Percutaneous Nephrolithotomy (PCNL)

For kidney stones that are exceptionally large, complex or several small stones bundled in one kidney, percutaneous nephrolithotomy (PCNL) is the most appropriate treatment. Conducted by a urologist, often assisted by an interventional radiologist, PCNL is typically an inpatient procedure requiring an overnight hospital stay. During the procedure, the urologist and radiologist collaborate to open a direct channel into the kidney’s drainage system via a small incision made in the back, often not larger than a dime.

After making the incision, the urologist uses a set of specialized tools to break the stones into pieces, which are then plucked out or vacuumed out of the kidney. With the procedure completed, a drainage stent or tube is left in place for temporary drainage of the kidney. For stones that are unusually large or complicated, the urologist may schedule a second “clean-up” surgery. In most cases, patients leave the hospital after PCNL within 24 hours of the procedure. And despite PCNL being a more invasive procedure than ureteroscopy and ESWL, it remains an effective and safe treatment that sees a high level of patient satisfaction.

Advantages of PCNL are:

  1. It is the gold standard treatment for very large or really complex stones.
  2. It is the most appropriate surgery for patients with a number of small stones bundled in one kidney.
  3. It clears most kidney stones fully in one procedure.
  4. It is highly safe and effective.

Limitations of PCNL are:

  1. A drainage tube or stent is necessary after the procedure, which may be uncomfortable for most patients.
  2. It is not appropriate for patients on blood-thinning medications.
  3. It is more invasive and so an overnight stay in hospital is a necessity.
  4. Though it clears most stones in one procedure, a repeat procedure may be necessary for the largest or most complex stones.
