Outcomes comparison of laparoscopic and open renal cyst unroofing

Objective: To compare the open and laparoscopic renal cyst unroofing and investigate the outcome of transperitoneal and retroperitoneal laparoscopic renal cyst unroofing. Methods: By using transperitoneal and retroperitoneal, renal cyst unroofing of 76 cases was performed. Among the 76 cases, renal cyst unroofing through transperitoneal approach or retroperitoneal approach was performed on 8 cases and 68 cases respectively. And open renal cyst unroofing of 38 cases was retrospectively analyzed. Results: Laparoscopy had advantages to open surgery in the average intraoperative blood loss, postoperative intestinal recovery, active time of post-operation and in-hospital days(P<0. 05). Conclusion: The therapeutic effects of transperitoneal or retroperitoneal laparoscopic renal cyst unroofing in treating simple renal cysts are superior to those by traditional open renal cyst unroofing.
