title: [Retroperitoneal laparoscopic unroofing of renal cyst: use of close method].
abstract: OBJECTIVE
  To study the close method of retroperitoneal laparoscopic unroofing of renal cyst.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  The laparoscopic procedure renders less trauma and discomfort to the patients and may be better indicated for symptomatic, simple renal cysts.
