Can a vasectomy reverse itself after 14 years?

A vasectomy is one of the safest and most effective birth control methods. But like other medical procedures, it isn’t foolproof. 

There is a possibility that a vasectomy can fail to prevent pregnancy in extremely rare cases with roughly a 1-percent chance of failure. 

Though vasectomy failures can be due to various reasons, several cases are due to a reversal of the procedure over time. 

How can a vasectomy reverse itself?

In rare instances, a vasectomy can reverse itself and is known to occur in about 0.025 percent of cases, equivalent to 1 reversal in 4,000 vasectomies. Such a reversal involves reconnection of the vas deferens after successful surgery and an effective post-vasectomy plan.

Remember that during a vasectomy, the vas deferens—the two tubes that carry sperm from the testicles to the urethra—are cut and sealed off to block sperm from reaching semen. The channel in the vas deferens is broken at the point where it is cut to eliminate the passageway of the sperm to combine with the semen.

However, in some cases, the vas deferens grow back several years after the procedure. The growth may continue until a connection is recreated, allowing the free flow of sperm to the urethra.

An extremely rare and successful reconnection can occur after 10 to 14 years or more and is usually almost impossible to notice. 

Most men only realize that their vas deferens have reconnected after their sexual partners get pregnant.

What can make a vasectomy reverse itself?

After a vasectomy, sperm may leak from the vasectomy site or a rupture and directly into the epididymis. Since sperm have immune system stimulating properties (antigenic qualities), it recognizes sperm as foreign and attacks them.

The sperm leakage triggers an inflammatory reaction that causes the body to develop pockets to trap the sperm in scar tissues and inflamed cells. 

With time, spheres of cells called sperm granulomas form and produce nodules in the vas deferens that may grow and result in the reconnection of the vas deferens. 

The risk of a reversal increases with the presence of sperm tissue at the vasectomy site.

Another reversal mechanism is scar tissue. 

With cells present after a vasectomy forming tiny channels that allow sperm to squirm their way through the tiny tears in the scar tissue, small drainage channels appear in the tissue on the ends of the severed vas deferens. Over time, these channels may reconnect to the divided vas deferens, providing a pathway for sperm to the seminal vesicles. The risk of a reversal via scar tissue increases with open-ended vasectomy, where only one end of the vas deferens is closed.

However, you shouldn’t be overly concerned if you consider a vasectomy or have already undergone the procedure.

The chances of a reversal are pretty rare—almost negligible—and extremely unlikely in most cases. 

At St. Pete Urology, we are proud of our excellent record of successful vasectomies. Our skilled and experienced urologists understand the factors that may lead to vasectomy failure, including non-severance of the vas deferens, non-observance of a period of sperm-free ejaculate, reconnection of the vas deferens, and duplication of the vas deferens. So we tailor and conduct every vasectomy under strictest adherence to best practices.

What is a PSA Test and When Should You Get It?

The PSA test measures the level or amount of PSA (prostate-specific antigen) in blood. The prostate-specific antigen is a protein synthesized by both non-cancerous and cancerous tissue in the prostate — a tiny gland found below the bladder in men. After it is produced, the PSA finds its way into semen and in small quantities in the blood. But since cancerous cells produce more PSA than non-cancerous cells, the test is carried out to detect high levels of PSA in blood, which may indicate the existence of prostate cancer.

What are the benefits of the PSA test?

Early detection of certain types of prostate cancer is critical for successful treatment and recovery. When the PSA test shows elevated levels of the antigen in blood, it may help to identify prostate cancer that is likely to grow quickly or spread to other parts of the body. In turn, the test helps to catch and treat such cancers early before they begin causing serious symptoms or become life-threatening. Also, by enabling early detection of prostate cancer when the necessary treatment is less aggressive, the test reduces the risk of certain adverse effects of treatment, such as urinary incontinence and erectile dysfunction.

What are the risks associated with the PSA test?

Carrying out the test itself comes with very little risk. It requires only a simple drawing of blood used to run the test in a laboratory. However, once the results of the test are out, there are a number of potential downsides involved. For instance, since false positives are quite common and elevated PSA results may have other causes other than prostate cancer, including prostate infection (prostatitis) and enlarged prostate (BPH), the test results may expose some patients to unnecessary or inappropriate treatments.

Some types of prostate cancer don’t produce much PSA, which means that a test may incorrectly indicate that you don’t have the cancer (a false negative). And follow-up tests for checking out the underlying causes of an elevated PSA test are often stressful, invasive, time-consuming or expensive. Furthermore, living with a localized or slow-growing prostate cancer — one that doesn’t require treatment — can cause stress and anxiety.

When should you get your first PSA test?

Before you get the first PSA test, it is recommended that you discuss the benefits and risks of the test with your doctor. During the discussion, a comprehensive review of your risk factors and preferences is done. For example, the urologist will consider your age, race, size of your prostate, medications you are taking (dutasteride and finasteride affect PSA levels), and how frequently your PSA levels change when making a decision about getting the test.

At St. Pete Urology, we advise men who are at higher risk of the disease, such as African American men and those with a brother or father who have had the cancer, to get their first test at the age of 40-45. Having the test before you reach 50 helps us to establish your PSA baseline and thereafter monitor the changes in your PSA levels to determine whether or not you’ll need annual PSA screening and prostate biopsy. If your blood PSA level is very low, we’ll put off any further PSA tests. But if you are a man of moderate to low risk of the disease, we recommend you get your first PSA test at age 50 or older (generally between 55 and 70).

What happens if your first PSA test result is high?

If you don’t have symptoms of prostate cancer, another PSA test may be recommended if your first test showed an elevated PSA level. The second test is used to confirm the validity of the original finding. But if the second PSA test still gives elevated PSA level, the urologist may direct that you continue with more PSA blood tests and digital rectal exams (DREs) at frequent intervals to monitor any changes in your prostate over time.

If your blood PSA level continues to rise over time or the urologist finds a suspicious lump in your prostate during a DRE, additional tests may be suggested to establish the nature of the problem. For example, a urine test may be run to find out if you have a UTI (urinary tract infection). Imaging tests like X-rays, cystoscopy or transrectal ultrasound also may be recommended. Then if prostate cancer is suspected, the urologist carries out a prostate biopsy — collecting multiple samples of tissue from your prostate by inserting hollow needles into the gland and withdrawing tissue. The tissues are examined under a microscope by a pathologist to confirm the cancer.

Treatment of prostate cancer

The type of treatment recommended for prostate cancer usually depends on whether it is early-stage or advanced-stage disease. For early-stage cancer the options include watchful waiting, radical prostatectomy, brachytherapy, conformal radiotherapy and intensity-modulated radiation therapy. At St Pete Urology, watchful waiting means no immediate treatment is offered but the cancer is closely monitored through regular PSA tests. Prostatectomy involves surgically removing part of or the entire prostate; brachytherapy involves implantation of radioactive seeds into the prostate to deliver specific amounts of radiation to the tumor. Conformal and intensity modulated radiotherapies deliver targeted amounts of radiation to the tumor with minimal damage or exposure of healthy tissues.

For advanced-stage prostate cancer, which is typically a more aggressive tumor that grows quickly and spreads faster to other areas of the body, treatment includes chemotherapy and androgen deprivation therapy. Chemotherapy can eliminate cancer cells that have spread to other parts of the body. Likewise, androgen deprivation therapy (androgen suppression therapy or ADT) is used to reduce the effect of androgens — male hormones that stimulate cancer growth — thereby slowing down or stopping cancer growth.

At St Pete Urology, we talk to our patients openly and candidly about the risks and benefits of the PSA test before we can advise them to get it. We also discuss the results of the tests, give our recommendations for those with positive results and typically repeat the PSA test for those with negative results. Our patients have always told us that our attention to detail, quality of interactions and efficiency during their visits is unmatched.

Urge Incontinence Treatment for Women

Urge incontinence is often a symptom of an unstable or overactive bladder. Characterized by a sudden strong desire to pass urine that can’t be postponed (urgency), urge incontinence usually comes with frequency (more often than normal) during the day and several times at night. Some women may even experience urine leakage during sex, particularly during orgasm. Although many women may avoid leakage by urinating frequently, they find the continual need to visit a bathroom quite restrictive to their lifestyles.

How do you know you have urge incontinence?

With urge incontinence, you will have urine loss because bladder muscles squeeze or contract at the wrong times. These contractions occur repeatedly, regardless of how much urine is in the bladder. There are 3 main indicators that you have urge incontinence:

  1. Inability to control when you urinate
  2. Having to pass urine frequently during the day and night
  3. Needing to pass urine suddenly and urgently

Causes of urge incontinence

There are two principal causes of urge incontinence. Irritation within the bladder may trigger incontinence. Or it may be loss of the nervous system’s inhibitory control on bladder contractions. For example, neurological conditions such as multiple sclerosis, spinal cord injuries, Parkinson’s disease and stroke may diminish bladder control and cause urge incontinence. Likewise, cardiovascular disorders, diabetes, bladder cancer, bladder stones, alcohol consumption, infections, diuretic medicine and inflammation that irritate the bladder or damage its nerves may cause incontinence. Urge incontinence also may indicate a more serious problem. For instance, when the urgency to pass urine is accompanied by blood in urine, recurrent urinary tract infections (UTIs) or an inability to empty the bladder completely, these may be red flags for a more serious issue than just urinary incontinence.

How is urge incontinence treated?

Generally a few lifestyle adjustments may help a woman cope with urge incontinence. For instance, making it as easy as possible to get to the bathroom, avoiding caffeine (tea, cola and coffee), avoiding alcohol, reducing amount of fluid intake per day and losing weight can help relieve symptoms. Secondly, bladder training (also called bladder drill) and pelvic floor muscle exercises can be combined to treat urge incontinence. A third solution may be treating urge incontinence with medicines called anticholinergics (antimuscarinics) such as oxybutynin, solifenacin, tolterodine, trospium chloride, propiverine, darifenacin and fesoterodine fumarate. And if the urge incontinence is associated with the lining of the vagina after menopause, applying estrogen cream directly inside the vagina may help.

Urge incontinence is also treated using Botulinum Toxin A (Botox), a prescription-only medication that relieves the incontinence when other options such as bladder training and other medication have failed. When these treatments are not successful, the urologist may suggest surgery. Surgical procedures for treating urge incontinence include sacral nerve stimulation, percutaneous posterior tibial nerve stimulation, augmentation cystoplasty and urinary diversion.

At St Pete Urology, our doors are open to all women troubled by incontinence. We are a recognized name in the urological community and boast of a team of highly innovative, experienced and certified physicians who deliver leading-edge urology and patient-centered care. We know there are many women who live with severe urological problems and we do our best to help those who come to us. We are good at treating these disorders.

What is the best treatment for urinary incontinence?

The sling procedure is the best, safest and most effective surgical operation for treating urinary stress incontinence. During the procedure, the urologist creates a sling using an artificial mesh, animal tissue or human tissue and places it under the urethra to support the urethra and bladder neck and to prevent unintentional urine loss.

What is stress incontinence?

Unintentional urine leakage (loss) occurs when you engage in physical activities or movements, such as running, sneezing, heavy-lifting, coughing or any action that puts stress (pressure) on your bladder. The condition is triggered by the weakening of pelvic floor muscles (the muscles supporting your bladder) and urinary sphincter muscles (muscles that control the release of urine).

Normally, as the bladder fills with urine and expands, the valve-like muscles in the urethra remain closed to prevent leakage of urine until you have reached the bathroom. However, if those muscles weaken and are not able to withstand pressure, then anything that exerts pressure on your pelvic and abdominal muscles can cause unintentional loss of urine.

Your sphincter and pelvic floor muscles may weaken because of:

  1. Type of childbirth/delivery.
  2. Previous pelvic or abdominal muscle surgery.
  3. Obesity/increased body weight.
  4. Smoking, which may trigger frequent coughing.
  5. Prolonged involvement in high-impact activities, such as running and jumping for several years.
  6. Age — the muscles weaken with increasing age.

You have stress urinary incontinence if you frequently leak urine when you:

  1. Sneeze
  2. Cough
  3. Stand up
  4. Laugh
  5. Have sex
  6. Get out of your car
  7. Exercise
  8. Lift something heavy

While stress incontinence does not imply that you will lose urine every time you do these things, you will most likely experience frequent leakage of urine when you engage in pressure-increasing activities.

Why should you undergo the sling procedure for stress urinary incontinence?

Having stress incontinence can be really awkward and embarrassing. In fact, with frequent leakage of urine, you may begin isolating yourself and limiting your social and work life. For instance, you may find it difficult to engage in exercise and in different leisure activities for fear of urine leakage. But with treatment, you can manage the incontinence and improve your overall quality of life and well-being. The sling procedure is ideal for you if you’ve tried other measures and still find urine leakage disruptive to your life.

How does the sling procedure work?

The sling procedure is aimed at closing your urethra and the neck of your bladder. For the procedure, your surgeon uses strips of synthetic mesh, animal tissue, donor tissue or your own tissue to develop a sling (hammock) that is inserted under your urethra or bladder neck. Once the sling is placed, it supports the urethra and ensures it remains closed — particularly when you are engaged in pressure-increasing activities such as coughing, laughing, sneezing or exercise — preventing the leakage of urine.

How is the sling procedure performed?

Before the procedure begins, you are placed under either general or spinal anesthesia. With general anesthesia, you will remain asleep throughout the procedure and will feel no pain. With spinal anesthesia, you are completely awake except that the area of your body from the waist down is numb and you don’t feel pain as the procedure is performed. Following application of anesthesia, the urologist places a tube (catheter) into your bladder to drain any urine already inside it.

The surgeon then proceeds to place the sling in any of the following ways:

1. Retropubic Method (Tension-Free Vaginal Tape/TVT Method): The surgeon makes a tiny incision inside your vagina, just under the urethra. Two other cuts are then made above your pubic bone — large enough to allow needles through. The surgeon uses a needle to place the sling beneath the urethra and behind the pubic bone. Using stitches or skin glue that is easily absorbed by the body, the surgeon closes off the cuts.

2. Single-Incision Mini Method: The surgeon makes a single tiny incision in the vagina, then passes the sling through it. No stitches are used to attach the sling, but over time the scar tissue grows and forms around it, keeping it in place.

3. Transobturator Method: The surgeon makes a tiny cut inside the vagina, just under the urethra. Two more cuts are made, one on each side of the labia (folds of skin on either side of the vagina). Using the incisions, the surgeon inserts the sling under the urethra.

At St Pete Urology, we perform hundreds of sling surgery procedures every year with remarkable results for our patients. The sling procedure is an outpatient operation that takes about one hour to complete and the patient is free to go home the same day. After the procedure, we arrange for follow-up sessions with our patients in the doctor’s office to assess the efficacy of the procedure and help with any complications that may arise. So if you are feeling embarrassed by stress urinary incontinence or have tried other measures without success, check with us to find out if the sling procedure can help you overcome the condition.

Treating Erectile Dysfunction with Inflatable Penile Prosthesis

Prescription medications are typically the first treatment offered for men with erectile dysfunction. But for those who don’t respond well or are unable to be treated with these pills, a penile implant is a useful alternative. The penile implant (also called penile prosthesis) is a medical device that is placed surgically into the penis to generate a natural-feeling and natural-looking erection.

Simple, outpatient procedure

The operation to place a penile prosthesis is a quick and simple procedure that takes about 1 hour to complete. The device is inserted into the penis and custom-fitted to help with erection. After it is placed, a man can go home the same day and is ready to enjoy sex after a 4-6 week recovery period.

What is a penile prosthesis?

An inflatable penile implant is a self-contained, fluid-filled, supple and durable system designed to mimic both the look and performance of the penis during a natural erection. It has three components: a reservoir that is placed in the abdomen, two cylinders inserted in the penis and a pump located in the scrotum. The two cylinders situated in the penis are connected to the saline reservoir using a tubing. Because of the three components, the penile prosthesis is known as the three-piece inflatable penile implant.

How does the penile implant work?

To inflate the penile prosthesis, a man presses the pump to transfer the saline from the reservoir into the cylinders located in the penis. The cylinders are then inflated and the penis becomes erect. When the deflation valve found at the base of the pump is pressed, the fluid moves back to the reservoir, deflating the penis and making it flaccid. So the penile implant is capable of producing erections that are satisfactory for sexual intercourse.

Why should men with ED consider penile implants?

Once placed surgically by a urologist, an inflatable penile prosthesis helps a man to regain control of his body. Unlike other ED treatment options which require a slightly longer waiting period before use, the implant can be used at any time. Penile implants are an ideal option for men whose ED has not been resolved by other treatment options. It is a cost-effective option that achieves 98 percent satisfaction rate with patients and is not noticeable in a flaccid penis. In fact, even your sex partners will not know that you have the implant unless you inform them.

If you are looking for something to make you a confident, self-assured man again, a penile prosthesis may be just what you need. It effectively mimics the look and performance of a natural penis and will enable you to begin enjoying sex as soon as you are recovered from the surgery. Unlike remembering to take your medication every time you want to have sex, a penile prosthesis offers a more permanent and natural solution.

What kinds of prostate problems are common in men over 50?

The prostate is a tiny walnut-sized gland that surrounds the urethra. But with hormonal changes that come with age, men of all ages usually experience changes in their prostate. As a result of these changes, prostate issues are quite common in men, particularly older ones. For example, the prostate often grows and swells with age, compressing the urethra and causing urinary issues.

Benign Prostatic Hyperplasia

With the prostate, there are usually two main issues: benign prostatic hyperplasia and prostate cancer. For men older than 50, benign prostatic hyperplasia (BPH) is the most frequent prostate issue. BPH, also called an enlarged prostate, means a non-cancerous increase in the number and size of prostate cells — so basically, it is an unhealthy increase in prostate size. While what triggers BPH isn’t well understood, it is believed that factors such as aging, inflammation, fibrosis and hormonal changes are the causes of the condition.

An enlarged prostate presses hard on the urethra and makes urination difficult. In men with the condition, symptoms include:

  1. Frequent urination, particularly at night.
  2. Difficulty starting a urine stream.
  3. Dribbling after passing urine.
  4. Weak urine stream, or a stream that starts and stops.
  5. Inability to empty the bladder completely.

But BPH also may have rare and more severe symptoms like:

  1. Urinary tract infection
  2. Blood in urine
  3. Inability to urinate

Prostate cancer

Prostate cancer is another frequent condition in men. In fact, it is the most common cancer after skin cancer, with about 1-in-6 American men being diagnosed with the disease during his lifetime. And like BPH, the cancer is most common in older men, with two-thirds of men diagnosed with the condition usually over age 65.

The cause of prostate cancer isn’t clear, but risk factors include age, family history, race and diet. The cancer grows slowly and rarely shows symptoms, so most men may never know that they have developed the disease until it is in advanced stage. But that also means only around 1-in-35 men with the cancer dies of the disease. Nevertheless, while some prostate cancers grow slowly and often require no or minimal treatment, there are other types that are quite aggressive and spread really quickly.

When caught early, there is a better chance of successfully treating the cancer. However, since it has similar symptoms to BPH, the condition is quite difficult to diagnose and by the time men see blood in their urine or feel chronic pain in their thighs, hips or lower back, it is often quite late. That is why it is critical for men of average to high risk of the cancer to have annual screening as early as appropriate.

Actually, for men of average risk of prostate cancer, the discussion to begin screening should start at the age of 50. While for those of higher risk, it is prudent to begin this discussion a little earlier, though not earlier than 40. But before screening, it is vital to discuss the risks and benefits of the testing with the doctor so the test offered meets the personal preferences and values of the patient.

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.

At St Pete Urology, we perform hundreds of minimally-invasive surgeries for kidney stones every year. We have several surgeons with extensive training, skill and experience in ESWL, ureteroscopy and PCNL, delivering excellent outcomes even for the most difficult kidney stones. Our collaborative, compassionate and patient-centered approach to care also means our patients enjoy utmost comfort and convenience throughout their procedures. So if you have symptoms of what you suspect to be kidney stones, don’t hesitate to come see us. We fix kidney stones safely and effectively.

What treatments are available for erectile dysfunction?

Are you struggling to achieve or maintain an erection? Whether you are under 35 or over 65, you are certainly not alone. Erectile dysfunction (ED) is quite common in American men, affecting more than 20 million men. Statistically, 52 percent of men between 40 and 70 years old have some form of erectile dysfunction while 25 percent of men younger than 40 suffer from the problem on a regular basis. At St Pete Urology, we see a lot of cases of erectile dysfunction every month, administer treatments and achieve excellent results for our patients.

Types of ED treatments

There are a number of safe and effective treatments for erectile dysfunction which, when properly applied, help in achieving and maintaining an erection for satisfactory sexual intercourse. The main treatments include oral medications, penile injections, vacuum erection devices and surgery. The choice of treatment depends on factors such as underlying causes and severity of the dysfunction, and overall health and preferences of the patient.

Oral medications

Dr. Adam Oppenheim of Advanced Urology InstituteAt St Pete Urology, oral medications are typically our first line of treatment. The medications commonly given are vardenafil (Levitra, Staxyn), sildenafil (Viagra), avanafil (Stendra) and tadalafil (Cialis). All these medications work by improving the action and efficacy of nitric oxide, which is a natural chemical produced by the body and used to relax penile muscles. With increased activity of nitric oxide due to these drugs, there is increased relaxation of the smooth muscles, improved blood flow to and in the penis and greater likelihood of developing an erection when there is sexual stimulation.

Though the oral ED drugs are similar in their mechanism of action, they vary slightly in chemical makeup, timing of dosage and expected period of effectiveness, and potential side effects. For instance, sildenafil (Viagra) produces the best effect when taken without food about one hour before sex and its effect lasts six hours. Vardenafil (Levitra, Staxyn) can be taken with or without food one hour before sex and its effect lasts seven hours. Like vardenafil, avanafil (Stendra) can be taken with or without food, but 15-30 minutes before sex (depending on the dose) and its effects lasts six hours. Tadalafil (Cialis) should be taken in small daily doses or in a large dose (as needed) with or without food about 1-2 hours before sex and its effect lasts 36 hours. Doctors usually consider these differences before prescribing oral ED medications.

Penile injections

An effective alternative to oral medications is injectable ED medicine. The specific injectable medication may vary, but some of the most commonly used ones are papaverine hydrochloride, alprostadil, prostaglandin E-1 and phentolamine. An injection of one or a blend of these ingredients will relax arterial wall muscles, cause increased blood flow into the penis and result in an erection. A small, sharp needle is used for the injection and there is only minimal discomfort. At St Pete Urology, we teach patients how to do the injections and once they have mastered it, then drugs are ordered and sent to them to do the injections at home.

Vacuum constriction devices

A vacuum device is an external pump supplied with a band to help trigger an erection by driving blood into the penis. Vacuum constriction devices (VCDs) have three components: the plastic tube placed around the penis, the pump that draws out air from the tube and creates a vacuum, and the elastic ring that helps to maintain an erection during intercourse by preventing the flow of blood back into the body. The elastic ring should only remain in place for a maximum of 30 minutes and then should be removed to restore normal blood circulation and prevent potential skin irritation. Using a vacuum pump requires adjustment and practice — it may make the penis feel numb or cold, purple in color and bruised, although such effects are often painless and go away in a few days. The devices also may weaken ejaculation, but they do not affect orgasm (pleasure of climax).

Implant surgery

Surgery is often a last resort treatment for ED. At St Pete Urology, we speak with our patients about whether or not surgery is right for them. Surgery can be done either to implant a device into the penis that makes it erect or rebuild the arteries and veins around the penis to improve blood flow. Implanted devices (prostheses) are an effective treatment for ED with implant surgeries typically taking about one hour to complete and usually done in outpatient setting.

There are two types of penile implants: inflatable implants that make the penis wider and longer via a pump in the scrotum and malleable implants that are basically rods allowing for manual adjustment of the position of the penis. Patients leave the hospital the day after their implant surgery and are able to use the implant to achieve an erection 4-6 weeks after surgery. Possible challenges with the implants include infection and breakage, but they are generally effective in getting and maintaining an erection.

Vascular reconstructive surgery

Another option is the urologist can perform a vascular or arterial reconstruction surgery to improve blood flow to and in the penis. Vascular reconstructive surgery is a highly delicate procedure involving either the re-routing of arterial pathways leading to the penis to bypass blocked arteries that are restricting blood flow, or to unblock blood vessels causing an obstruction. An artery can be bypassed by moving an abdominal muscle artery to a penile artery. Alternatively, a penile vein can be modified to work like an artery.

Men who are younger than 45 are the ideal candidates for reconstructive surgery, especially those who have experienced trauma or injury that resulted in the damage to blood vessels at the base of the penis. The goal of the procedure is to remove or bypass any blockages that may impede blood flow to the penis. And with the obstruction removed, there is increased blood flow to the penis and greater likelihood of an erection.

If you have erectile dysfunction, the first step is to speak with a doctor. The right treatment for you will depend on your overall health and the underlying cause of your ED. At St Pete Urology, we see a lot of cases of erectile dysfunction and endeavor to achieve the best possible outcomes for our patients.
