Abstract

Caliceal diverticula containing calculi had been managed conventionally by deroofing of the diverticulum, closure of the communication with the collecting system, or partial nephrectomy. To minimize the loss of the renal parenchyme and to treat caliceal diverticulum containing calculi, endoscopic procedure was performed successfully in 6 cases. but failed in 1. Repeated endoscopic procedure was performed in failed case 6 months after first operation and succeeded also. The diverticular neck was dilated with the Amplatz dilator upto 24-30Fr. A 20Fr. nephrostomy catheter was placed for 10-14days, and there was no complications. We evaluated the result of diverticular obliteration with excretory urography 6 months after the operation. In conclusion, endourologic management of caliceal diverticulum containing calculi is a safe. less invasive. successful and parenchyme preserving procedure.
