不同大小双通道经皮肾镜碎石治疗鹿角形肾结石的疗效观察

Clinical observation of treating renal staghorn calculi with percutaneous nephrolithotomy by different inside diamete double channel

目的比较不同大小双通道经皮肾镜碎石治疗鹿角形肾结石的疗效。方法选择32例鹿角形肾结石患者,根据手术通道大小分为双标准通道组(观察组)20例和微通道联合标准通道组(对照组)12例,比较两组手术情况。结果观察组的手术时间明显低于对照组,术中出血量、并发症发生率明显高于对照组。结论双标准通道经皮肾取石术、微通道联合标准通道经皮肾取石术治疗鹿角型结石均能获得较好的近远期疗效,而穿刺点及穿刺时机选择是双通道手术成功的关键所在。

Objective To investigate the clinical effect of treating renal staghorn calculi with percutaneous nephrolithotomy by different inside diamete double channel Methods 32 patients with staghorn renal calculi were selected, according to size of operation channel, they were divided into double standard channel group （A group） 20 patients, micro channel combined with standard channel group （B group） 12 patients. The operation situation were compared between two groups. Results Operation time of A group were significantly lower than those of B group. During the operation amount of bleeding, incidence rate of complication were significantly higher than those of B group. Conclusion Double standard channel PCNL,micro channel combined with standard PCNL channel treating staghorn renal calculi all can get better short and long term curative effect, while point of puncture and timing of puncture are key of dual channel operation suc- cess.
