Ureteral Stones (Ureterolithiasis)

Ureteral stones, or ureterolithiasis, are small, hard deposits that form in the urinary tract, specifically in the ureters, which are tubes connecting the kidneys to the bladder. These stones can develop when minerals and salts in urine crystallize. People may experience severe pain, especially in the lower back or abdomen, as the stone moves and obstructs the urinary flow. Other symptoms can include blood in urine and frequent urination. Treatment options vary based on the size of the stone and may include increasing fluid intake, medication, or procedures to remove the stones if they cause significant problems.
