在不控制肾蒂血流的情况下,采用肾盂联合肾实质切开治疗充填型肾结石35例,结果33例患肾功能逐渐恢复,尿量增加。强调充填型肾结石患肾功能严重受损,阻断肾蒂血流后,尽管有预防措施,仍会对肾功能加重损害。部分病例的肾积水使肾实质变薄,长期伴炎症刺激,肾弓形动脉和小叶间动脉变细,管腔狭窄,肾组织部分纤维化,使术中出血减少,可按结石所在部位切开局部肾盏取出结石,一般来说这种手术方法是安全的。
In the absence of control of renal pedicle blood flow, the use of renal pelvis combined with renal parenchymal incision in the treatment of 35 cases of filling stones, the results of 33 patients with renal function gradually recovered, urine output increased. Emphasize that the filling of renal stones with severe renal impairment, blocking the pedicle of the renal pedicle, despite precautionary measures, will still aggravate renal dysfunction. In some cases, hydronephrosis thinning of the renal parenchyma, long-term inflammation accompanied by irritation, renal arcuate artery and interlobular arteries thinning, stenosis, renal tissue fibrosis, so that surgery to reduce bleeding, the site can be cut according to the stones Local calyx removal of stones, in general, this surgical method is safe.
