Ureteral Stones
Ureteral stones are stones that form in the urinary tract (Bladder Infection Causes | Catheter). Most patients with ureteral stones associate them with extreme pain. The pain starts as the stone moves into the urinary tract, causing blockage and irritation (Bladder Pains and Irritants). A sharp, throbbing pain is felt in the back and on the side of the kidney, which radiates to the groin. Other symptoms of ureteral stones include blood in the urine, nausea, and vomiting.
