title: [Lumboscopic treatment of simple renal cysts: initial experience with 17 cases].
abstract: OBJECTIVE
  To evaluate the feasibility of lumboscopic treatment of simple renal cysts.
  
  
  METHODS
  From January 1999 to January 2002, 17 patients with a mean age of 40 years were operated for symptomatic renal cysts via a retroperitoneal approach. All patients were evaluated by preoperative ultrasonography and CT. A Bosniak type I cyst was diagnosed in 10 cases and a Bosniak type II cyst was diagnosed in 7 cases. The mean cyst diameter was 7 cm (range: 5 to 15 cm).
  
  
  RESULTS
  All patients were operated via an exclusively retroperitoneal approach. The mean operating time was 50 min (range: 40 mm-120 mm). The estimated mean blood loss was 80 cc. No conversion was necessary and the mean length of hospital stay was 1.5 days. All cysts were histologically benign. All 17 patients are asymptomatic (mean follow-up = 11 months) with no radiological signs of recurrence.
  
  
  CONCLUSIONS
  Lumboscopic treatment of simple renal cysts appears to be a feasible, safe, effective and satisfactory technique in terms of morbidity, operating time, complications and blood loss.
