title: Laparoscopic partial nephrectomy with selective polar clamping using the simon clamp: initial experience.
abstract: OBJECTIVE
  To report our initial experience in 3 cases of laparoscopic partial nephrectomy with selective parenchymal clamping using a novel laparoscopic clamp.
  
  
  METHODS
  A total of 3 laparoscopic partial nephrectomies were performed using the Simon clamp (Aesculap). Mean patient age was 67 years (range 60 to 74 years), two patients were males. All patients had an ASA score of 2. Mean tumor size was 2.2 cm (range 2 to 2.4 cm) and all tumors were of the lower pole. Two tumors were on the right kidney and one on the left kidney.
  
  
  RESULTS
  Mean operative time was 100 minutes (range 70 to 120 min). Mean operative bleeding was 16 ml (range 0 to 50 ml). Mean warm ischemia time of the renal pole was 33 minutes (range 30 to 40 min). All patients were discharged on postoperative day 2. There was no intra or postoperative complications. Surgical margins were negative in all cases.
  
  
  CONCLUSIONS
  The Simon clamp allows for tumor resection without bleeding and for renal defect repair without collateral renal injury. We hope that in the future the development of other instruments will allow for selective clamping in any tumor location.
