二期微创经皮肾镜术中肾盂内压的监测及其临床意义

目的：研究二期微创经皮肾镜碎石（MPCNL）术中肾盂内压力的变化及其对术后并发症的影响。方法：行MPCNL手术的60例肾结石患者术中均行持续肾盂内压监测，试验组（30例）为二期手术患者，对照组（30例）为一期手术患者。统计术后发热、疼痛指数及血红蛋白的下降值等相关临床指标，探讨其与肾盂内压监测的关系。结果：二期MPCNL术中肾盂内压明显低于一期MPCNL者，二期手术患者术后发热、血红蛋白下降值及疼痛指数均明显低于对照组（P〈0．05）。结论：二期MPCN手术由于有成熟的经皮通道，通过减少术中高压灌注时间，可以显著降低术后并发症发生率。

The application of intrapelvic pressure monitoring in Two-stage percutaneous nephrolithotomy and its clinical significance

Objective：To introduce the application of the continuous intraoperative renal pelvic pressure monb toring in two stage percutaneous nephrolithotomy and investigate its clinical significance. Methods： 60 patients with kidney stones were divided into two groups： experimental group （30 cases） and control group （30 cases）. All patients were performed continuous intraoperative renal pelvic pressure monitoring during MPCNL. The relationship between postoperative fever, pain scores, hemoglobin decline and intrapelvic pressure monitoring were discussed. Results： The postoperative fever, decline in hemoglobin and pain scores of the experimental group were significantly lower than the control group （p〈0.05）. Conclusions：Two-stage percutaneous nephrolithotomy could reduce the intrapelvic pressure and postoperative complications significantly.
