目的探索治疗嵌顿性肾盏结石，既能满意取石又能最大限度地保护肾功能，减少并发症的手术方法。方法用自行设计的原位撑开的手术方法治疗嵌顿性肾益结石59例。结果与对照组相比，治疗组手术时间短，术中需输血的人数少，术后血尿者少，尿瘘发生率低，住院时间短，术后肾功能恢复好。结论该手术方法操作简单，肾表面距结石的距离最近，取石时定位准确，容易，出血少，不阻断肾血流，取石不受时间限制，不损伤主要血管，对肾功能影响小，术后并发症少。易于推广。
Objective To explore the surgical treatment of incarcerated calyceal calculus, which can both satisfy the stone extraction and maximize the renal function and reduce the complications. Methods 59 cases of incarcerated kidney benefit stones were treated by self-designed open surgery. Results Compared with the control group, the treatment group had shorter operation time, fewer blood transfusions during operation, less postoperative hematuria, lower incidence of urinary fistulas, shorter hospital stay, and better postoperative renal function recovery. Conclusion The operation method is simple, the distance between the surface of the kidney and the stone is the nearest, accurate and easy to get the stone when taking the stone, less bleeding, does not block the renal blood flow, stone is not subject to time constraints, does not damage the main blood vessels, After complications less. Easy to promote.
