In our study, we assessed the efficacy, safety, and feasibility of laparoscopic decortication of symptomatic simple renal cysts using conventional monopolar device. Long-term symptomatic and radiological results of 15 patients who underwent laparoscopic renal symptomatic simple cyst decortication, which was performed by conventional monopolar device, were retrospectively reviewed. The mean age of the patients was 49.7 years. There were nine male and six female patients. Their presenting symptoms were lumber pain in 93% (n = 14), and hypertension in 7% (n = 1). The mean operating time was 64.6 minutes. The mean hospital stay was 2.2 days. After a mean follow up of 12.08 months, the radiological and symptomatic successes were 100% and 86.6%, respectively. Laparoscopic renal cyst decortication using conventional monopolar device represents an effective and safe treatment option in the management of renal cyst without any need for more expensive energy sources.
