Role of ureterorenoscopy in bypassing the ureteric obstruction

ABSTRACT

To ascertain the efficacy of transurethral ureterorenoscopy [URS] in the management of ureteral obstruction. This study was conducted from June 2005 to August 2006 at the Department of Urology and Renal Transplantation, Allied Hospital/Punjab Medical College, Faisalabad. A total number of 198 patients with ureteral obstruction due to any cause were included in the study. Cause of ureteral obstruction was stones in 172 patients, encrusted and upward migrated Double J [DJ] ureteric stent in 06 patients, ureteric tumors 03 patients and ureteric injuries in 10 patients. Ureteral obstruction was relieved by completely clearing the stone in 98% patients; encrusted and upward migrated ureteric stents were removed in 100% patients. latrogenic ureteric obstruction was bypassed in 30% of patients. There was failure to negotiate ureteric orifice by ureterorenoscopy in 07 patients due to oedema at ureteric orifice. There was no significant complication during the procedure. Ureterorenoscopy is superior procedure in the diagnosis and treatment of ureteric obstruction due to any cause at any level except the iatrogenic ureteric obstruction where it has limited role
