A clinical analysis of techniques of renal artery control in laparoscopic donor nephrectomy / 中华器官移植杂志

ABSTRACT

Objective To analyze the clinical techniques of renal artery control in laparoscopic donor nephrectomy.Methods 211 relative living renal transplantations were performed from June 2003 to June 2012,and 136 donors underwent laparoscopic donor living nephrectomy (LDN) since 2007.Forty donors were subjected to the Hem-o-lock clips for renal artery control by open surgery,87 donors to the Hem-o-lock clips for renal artery control by laparoscope,5 donors to the Endo GIA stapler for renal artery control by laparoscope,and 4 donors to the Hem-o-lock clips by laparoscope combined with hand-assisted suture transfixion for renal artery control.Results The warm ischemia time of renal artery control was shortest (1.1 ± 0.3 min) by Hem-o-lock clips in open surgery,and longest (3.2 ± 0.8) min by the Hem-o-lock clips with laparoscope.There was significant difference in the warm ischemia time of renal artery between open group and other groups,the differences (P＜0.05).The comparison of prognostic factors in the transplant renal outcome showed no significant difference among groups.The renal arterial stump-rrhexis-caused massive secondary bleeding occurred in 1 case subject to Hem-o-lock clips for renal artery control by laparoscope,with conversion to open surgery urgently,the operation was successful at last.Other renal artery control ways were all safe without any adverse reaction.Conclusion The warm ischemia time of renal artery control by Hem-o-lock clips in open surgery was shortest in laparoscopic donor nephrectomy.The renal artery control way by Endo GIA stapler in laparoscope or by Hem-o-lock clips with hand-assisted suture transfixion is safest.The utilization of Hem-o-lock clips should be careful in high risk population such as severe atherosclerosis etc.
