title: [Laparoscopic partial nephrectomy for small renal tumors: report of 59 cases].
abstract: OBJECTIVE
  To report our initial experiences of laparoscopic partial nephrectomy (LPN) for small renal tumors.
  
  
  METHODS
  From July 2005 to December 2008, 59 patients with small renal tumors were resected by laparoscopic partial nephrectomy.
  
  
  RESULTS
  All operations were successfully accomplished. Twenty-seven patients were treated via a transperitoneal approach and the other 32 cases a retroperitoneal approach. The average operative duration was 72 minutes (range: 60 -) and the average kidney ischemia time 19 minutes (range: 15 - 32). The estimated blood loss was from 20 - 50 ml and no patient needed transfusion. The collecting system closure was performed by suture in 2 patients, and no complication of hemorrhage or urine leak was found. Thirteen cases used Hemo-lok to clamp the suture instead of traditional ligature. And the mean time of renal warm ischemia was 13 minutes (range: 10 - 18). These patients included 55 with clear cell renal carcinoma, 3 with granule cell renal carcinoma and 1 with oxyphil cell renal carcinoma. All renal tumors were completely removed with a negative surgical margin. The mean postoperative hospital stay was 6.2 days (range: 5 - 10). The postoperative ECT and creatinine were normal and there was no significant difference as compared with the preoperative findings (P < 0.05). None patient had any local recurrence during a mean follow-up period of 24.6 months (range: 3 - 42).
  
  
  CONCLUSIONS
  LPN for pT(1) stage renal tumor is both safe and feasible. Mastering the skilled laparoscopic techniques may facilitate operation. Employing Hemo-lok instead of traditional ligature to clamp the suture while sewing renal wound shortens the warm ischemia time.
