后腹腔镜治疗肾盂单发较大结石分析

目的探讨后腹腔镜肾盂切开取石术治疗肾盂单发较大结石的临床效果。方法肾盂单发较大结石患者51例，均为肾外型肾盂，采用后腹腔镜肾盂切开取石术，分析手术各相关指标及并发症的发生情况。结果51例均一期手术成功，无中转开放手术病例，平均手术时间为（139．24±34．21）min，平均出血量为（56．43±13．17）ml，无输血病例，结石清除率为100％，术后发热率为3．92％，术后平均住院日为（4．87±0．71）d，术后。肾功能较术前差异无统计学意义沪〉0．05）。结论对于良好选择的病例，后腹腔镜肾盂切开取石术具有出血少、结石清除率高、术后并发症少等优势，可作为肾盂单发较大结石的可选术式。

Laparoscopic retroperitoneal pyelolithotomy in the treatment of solitary large renal pelvic stone

Objective To investigate the clinical effect of laparoscopic retroperitoneal pyelolithotomy （LRP） in the management of solitary large renal pelvic stones. Methods Setected 51 patients with solitary large renal pelvic stones and treated by LRP. We analyzed the occurrence of the relevant indicators and surgical complications. Results All of the 51 patients were down by LRP once successfully, and none of them conversion to open surgery. Without blood transfusion, the mean operative time was （139.24 ± 34.21）rain, mean estimatedblood loss was （56.43 ±13.17）ml, mean postoperative hospital stay was （4.87 ± 0.71）d, rate of postoperative fever was 3.92%, and stone-free rate was 100%. Compared with before surgery no significant difference was found in renal function. Conclusion With the advantage of less bleeding, high stone-free rate, less postoperative complications and lower postoperative hospital stay, LRP is another feasible surgical technique for well-selected patients with large renal pelvic stones.
