Objective: To study the close method of retroperitoneal laparoscopic unroofing of renal cyst.
Method: A close method retroperitoneal laparoscopic unroofing of renal cyst was attempted in 35 cases between May 1995 and December 1996. The age of the patients ranged from 30 to 72 and the cyst size from 4.0 to 9.3 cm.
Results: The operative procedure took around 50 minutes. After a 1 - 18 month follow up, we observed the disappearance of all renal cysts.
Conclusion: The laparoscopic procedure renders less trauma and discomfort to the patients and may be better indicated for symptomatic, simple renal cysts.
