## Overview Ureterolithiasis is the presence of stones lodged in the ureter. Stones cause flank pain, blood in the urine, and hydronephrosis. They are less common than bladder stones but more difficult to manage because of their location. ## Causes Mineral precipitation, usually calcium carbonate. ## Diagnosis Ultrasound, urinalysis showing blood, and sometimes contrast studies. ## Treatment Surgical removal when accessible. Lithotripsy is rarely available. Prognosis is guarded. ## Recovery and Prognosis Guarded. ## Prevention None specific.
