Retroperitoneoscopic deroofing of peripelvic renal cysts

Objective To evaluate the safety and feasibility of performing retroperitoneoscopic cystectomy of peripelvic renal cysts.Methods Five men and eleven women (mean age 38.2) with a peripelvic renal cyst associated with ipsilateral flank pain were treated by retroperitoneoscopic deroofing using a three-port technique. Cyst size ranged from 2.4 to 5.7 cm. Patients were followed with radio-logic imaging and B-utrasonography at 3 and 6 months thereafter. Results In all cases, the laparoscopic procedure was suecossful.The operative time ranged from 30 to 100 minutes (mean 50 minutes), and the mean blood loss was < 100 ml. The mean postoperative hospital stay was 5 days (range 3-8 days). At a mean follow-up of 3 months, symptoms and collecting system obstruction had re-solved in all patients. Conclusion Although retroperitoneoscopic cystectomy of peripelvie renal cysts is technically challenging, it is a safe and efficacious procedure and offers a favorable minimally invasive alternative for the treatment of symptomatic cysts.
