Flexible Ureterorenoscopy, Dilatation of the Narrow Calyceal Neck and Extracorporeal Shock Wave Lithotripsy: A New, Minimally Invasive Approach to Stones in Calyceal Diverticula
Between January 1988 and December 1988,15 patients with symptomatic stones in calyceal diverticula or non-visible calices received treatment at the UCLA Stone Center. All patients were further evaluated with flexible ureterorenoscopy to identify narrow intrarenal segments. Dilatation of narrow intrarenal segments was performed along with direct endoscopic stone removal and/or extracorporeal shock wave lithotripsy (ESWL*) under the same anesthesia. In all cases access to the targeted cavity was gained, and dilatation of the narrow connection was successfully performed. Eleven of 15 patients were rendered completely stone free;two of four with residual debris remained symptom free. No complications from the endoscopic procedures or the ESWL treatments were noted.
