[Transurethral ureterolithotripsy using a rigid ureteroscope].

Eighty patients with ureteral stones underwent transurethral ureterolithotripsy using a rigid ureteroscope. In 68 of the patients (85%), the stones were removed successfully. Most of the 12 failures were removed by a percutaneous approach. The main complications of transurethral ureterolithotripsy were high fever (35%), ureteral injury (10%) and ureteral stricture (1.6%). Ureteroscopic procedures are thought to be useful in stone removal and diagnostic evaluation of abnormality of upper urinary tract.
