Kidney stones are small deposits of minerals that form hard stones in the kidney. They can cause urine blockage if a kidney stone obstructs the flow of urine through the ureter. The blockage can lead to kidney damage resulting from an accumulation of toxins in the urine. Symptoms include pain in the abdomen between the ribs and hip, or pain in the lower abdomen, lower back or groin. To learn more about the Signs and Symptoms of Kidney Stones, call (727) 478-1172.
