title: Is retroperitoneoscopic renal ablative surgery easier and safer using a new hemostatic device compared with clips and monopolar coagulation? A comparative study.
abstract: OBJECTIVE
  The aim of study was to retrospectively analyze our series of total and partial retroperiotoneoscopic nephrectomies performed in the last 5 years.
  
  
  METHODS
  Twenty-two procedures were performed, 20 patients underwent nephrectomy and 2 patients underwent partial nephrectomy. The 20 patients who underwent nephrectomy were divided in 2 groups: group 1 (G1) patients-1-10, for whom we performed the procedure using monopolar coagulation, and group 2 (G2) patients 11-20 for whom we used a new hemostatic device to perform dissection and hemostasis. The results were analyzed using χ2 test. The results of partial nephrectomies were analyzed separately.
  
  
  RESULTS
  No conversion were reported. We analyzed 6 parameters to compare the results: operative time (OT), estimated blood loss (EBL), need for transfusion (NT), complications, time to oral intake (TOI), hospital stay (HS). OT in G1 was in median 85 minutes, in G2 65 minutes (P=0.004); EBL was 15 mL for G1 and 5 mL for G2 (P=0.000.), NT was not necessary in both, in G1 we had 2 complications and 1 complication in G2; TOI was day 1 for both groups; median HS was 3 days for both. As for heminephrectomy, OT was 120 and 140 min, EBL 30 mL in both, NT not necessary, TOI was 1 day and HS 4 and 5 days respectively.
  
  
  CONCLUSIONS
  Our study shows that the use of a new hemostatic devices reduce significantly OT and EBL in children underwent renal ablative surgery for benign pathologies compared with the use of monopolar coagulation.
