摘要 目的 探讨24 F球囊扩张法经皮肾镜取石术处理鹿角形结石的安全性及有效性.方法 回顾性分析2013年4月至2014年4月收治的64例鹿角形肾结石患者的临床资料,按通道扩张方式分为球囊组(采用球囊扩张器扩张至24 F,31例)和筋膜扩张器组(采用筋膜扩张器扩张至16 F,33例).两组患者的性别、年龄、体质指数以及结石位置和大小比较差异均无统计学意义(P>0.05).分别记录两组的建立通道时间、一次通道建立成功率、穿刺并发症(肾盏破裂、肾周积液及术后延迟性出血等)、清除结石时间、结石清除率、术后血红蛋白下降值、术后发热>37.5℃例数等.测量并记录两组术中肾盂内压变化. 结果 球囊组及筋膜扩张器组建立通道时间[(5.6±2.1)、(9.4±1.7) min]、一次通道建立成功率[100%(31/31)、88% (29/33)]、清除结石时间[(32.4±3.4)、(49.5±3.7) min]、一期结石清除率[84%(26/31)、61%(20/33)]、术后血红蛋白下降值[(16.7±3.3)、(28.4±2.6) g/L]、术中肾盂内压[(19±3)、(25±6) mmHg,1 mmHg=0.133 kPa]及术后发热率[16%(5/31)和39%(13/33)]比较差异均有统计学意义(P<0.05).64例均未损伤胸膜、脾脏及十二指肠等邻近脏器. 结论 应用球囊扩张法建立24 F经皮肾通道快速、安全、出血少,术中肾盂内压低,应用于鹿角形结石经皮肾镜取石术时结石清除率高、并发症少. Objective To access the safety and efficacy of balloon dilation in percutaneous nephrolithotomy for staghorn stones.Methods Clinical data of 64 patients with staghorn stone according to the inclusion criteria in our institution from April 2013 to April 2014 were collected and analyzed retrospectively.According to the dilation methods,the patients were divided into balloon dilation group (dilated to 24 F by balloon dilator,31 cases) and fascial dilation group (dilated to 16 F by Amplatz fascial dilator,33 cases).There was no significant difference in sex,age,body mass index between the 2 groups.The data of duration of percutaneous access,one-attempt success rate of dilation,puncture complications (kidney calices fracture,perinephric fluid collection and postoperative delayed hemorrhage etc.),removing stones time,stone free rate,hemoglobin drop after surgery and number of patients who experienced postoperative fever >37.5 ℃ were recorded.Results Compare to fascial dilation group,balloon dilatation group had significant differences in terms of duration of percutaneous access [(5.6± 2.1) min versus (9.4± 1.7) min],oneattempt success rate of dilation[100% (31/31) versus 88% (29/33)],removing stone time[(32.4±3.4) min versus (49.5±3.7) min],stone free rate [84% (26/31) versus 61% (20/33)],hemoglobin drop after surgery [(16.7±3.3) g/L versus (28.4±2.6) g/L],renal intrapelvic pressure[(19±3) mmHg versus (25±6) mmHg] and rate of patients who experienced postoperative fever >37.5 ℃ [16% (5/31) versus 39%(13/33)] (P<0.05).No injury of adjacent organs,including pleura,liver,spleen,or bowel was noted in all patients.Conclusions Balloon dilation is quick and safe with less hemorrhage when building percutaneous renal channel.And it has higher stone free rate and less complication rate in percutaneous nephrolithotomy with staghorn stones.
