The aim is to study the outcome of laparoscopic decortication of symptomatic simple renal cyst with omental wadding technique in a single center.

This is a retrospective study of 16 consecutive patients who underwent transperitoneal laparoscopic decortication of symptomatic simple renal cyst with omental wadding technique between November 2007 and November 2011. The indication for surgery was for relief of pain in all cases. Pain was assessed preoperatively and 1 and 6 months postopertively using numerical rating pain scale. All cysts were more than 10 cm in its greatest dimension. Laparoscopic decortication was the primary treatment in 13 cases and the secondary treatment in three cases after sclerotherapy. We used the omental wadding technique to decrease the incidence of recurrence. We reviewed the preoperative and postoperative data.

The operation was successfully completed laparoscopically in all cases with a mean operative time of 95 minutes without major perioperative complications. Hospital stay was 2.4 days (range, 2 to 4 days). Fifteen cases improved significantly after operation in a mean follow-up of 1.5 year. One case only had radiological recurrence after 6 months postoperatively.

Laparoscopic decortication of large simple renal cysts is an efficacious, safe and less invasive method of treatment. Omental wadding is helpful to decrease the incidence of cyst recurrence. Laparoscopic decortication is recommended as a primary treatment for huge cysts or as a secondary treatment after treatment failure with sclerotherapy.
