肾上、下极的肾盏多发性结石,历年来常采用经肾盂、肾实质切开取石,或阻断肾蒂血流,局部低温下肾部份切除术等。但由于肾盂肾实质切开取石,不能顺利的达到取石彻底,术中出血多,损伤较大,效果不满意。而阻断肾蒂血流,常因肾缺血时间过久,造成该肾实质严重的缺血性损害,以致个别病例在次年复查静脉血盂造影见,该肾已完全丧失功能。为 Renal upper and lower pole of the calyceal multiple stones over the years often used by the renal pelvis, renal parenchyma cut stone, or blocking the pedicle of the renal blood flow, local partial low temperature renal resection and so on. However, due to renal parenchymal stone removal, can not successfully achieve a complete stone, bleeding and more, greater damage, the effect is not satisfied. The block of the renal pedicle blood flow, often due to renal ischemia for too long, resulting in severe renal ischemic damage, resulting in individual cases in the following year review of venous angiography seen, the kidney has completely lost its function. for
