Retroperitoneal Laparoscopic Renal Cyst Marsupialization / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Retroperitoneoscopy has begun to gain its acceptance for urologic surgery, the aim of this study was to assess the clinical efficacy and safety of retroperitoneal laparoscopic surgery for simple renal cysts. MATERIALS AND METHODS: Three female and five male patients ranging from 37 to 72 years in age underwent retroperitoneal laparoscopic marsupialization of symptomatic renal cysts from March 1996 to February 1998. The retroperitoneal space was created by saline-filled balloon made of middle finger of a No 8 surgical glove and 16Fr Foley catheter. Two patients had prior percutaneous cyst aspiration and sclerotherapy and two patient had a parapelvic renal cyst. We assessed the mean operative time, postoperative hospital stay and complications. RESULTS: Mean operative time was 98 minutes(range; 80-140), the average postoperative hospital stay was 2.5 days(range; 2-3). All eight patients were successfully managed and have remained pain free with no evidence of recurrence of the cyst at the 3-12months follow-up. Complications included 2 cases of subcutaneous emphysema and 1 case of peritoneal tear. CONCLUSIONS: Retroperitoneal laparoscopic unroofing is a safe, effective, and minimally invasive treatment for symptomatic or recurrent renal cyst.
