肾部分切除术,在完全游离肾脏后,常规采用无损伤血管钳(如布氏血管钳等)完全阻断肾动脉供血,由于完全阻断肾血流对肾脏组织会造成缺血性损害,甚至有不可逆性损害;且阻断时间一般不超过三十分钟,在短时间内行此项手术有一定的困难;手术部位较深,血管钳本身的占位对手术操作亦带来一定的困难。为避免以上不利因素,我们采用徒手局部压迫止血代替血管钳完全性肾血流的阻断,收到较好的效果,现简要介绍如下:
Partial nephrectomy, completely free of the kidneys, routine use of non-invasive vascular forceps (such as Buchner forceps, etc.) completely blocked the renal artery blood supply, due to completely blocking the renal blood flow to the kidney tissue will cause ischemic damage, or even There is irreversible damage; and the blocking time is generally not more than thirty minutes in a short period of time to perform this operation has some difficulties; deep surgical site, vascular clamp itself occupies a position on the operation also brings some difficulties. In order to avoid the above unfavorable factors, we use the free hand local compression hemostasis instead of vascular clamp complete renal blood flow block, received good results, are briefly described as follows:
