Endoscopic management of ureteric calculi

A study involving 60 patients with ureteric calculi was conducted at the Department of Urology, Lahore General Hospital, from January 1991 to December 1993. The purpose of this study was to evaluate the efficacy and complications of uretero-renoscopy for ureteric calculi. This procedure was performed for fragmentation or removal of stone with the help of auxiliary instruments where possible. The study group predominantly consisted of male patients more than 14 years of age having ureteric calculi larger than 5 mm in diameter. The overall success rate of fragmentation, removal or push/bang of ureteric Galculi was 66.7 percent. In 15 patients although ureteric orifice was negotiated, the calculi could not be accessed either due to failure of visualization [n=8] or due to oedema and narrowing of lumen [n=7]. In five patients [25 percent] we failed to negotiate ureteric lumen due to narrow ureteric orifice. Perforation of ureter [n=1] and mucosal injury [n=1] occurred during the procedure. Fever in postoperative period occurred in three patients
