Urinary Tract Stones (Urolithiasis)
Stones are heavy masses that form in the urinary tract and cause pain, bleeding or an infection or blockage of urine flow.
Tiny stones may cause no symptoms, but larger stones can cause excruciating pain in the area between the ribs and hips in the back.
Usually, an imaging test and an analysis of urine are done to diagnose stones.
Sometimes stone formation can be prevented by changing the diet or increasing fluid intake.
Stones that do not pass on their own are removed with lithotripsy or an endoscopic technique.
Stones in the urinary tract form in a kidney and grow into a ureter or bladder. The formation of stones is called urolithiasis, kidney lithiasis or nephrolithiasis, and the place where the stones are located has a specific name: ureteral stone or bladder stone.
