CT尿路造影在经皮肾镜碎石取石术中的应用价值

摘要

目的 探讨CT尿路造影(CT urography,CTU)在经皮肾镜碎石取石术中的应用价值.方法 选取2014年6月至2016年6月于本院治疗的82例肾结石或输尿管上段结石患者为研究对象.采用随机数表法将入选患者分为观察组(40例)和对照组(42例).对照组患者行泌尿系CT平扫,观察组患者行128排CT扫描,获得CTU图像,进行图像后处理.于B超引导下穿刺目标肾盏成功后,采用超声/弹道碎石系统将结石完全击碎,术后复查腹部平片了解结石残留情况.结果 观察组患者手术时间和住院天数均显著短于对照组(P<0.05),术中出血量和灌注液使用量均显著少于对照组(P<0.05),穿刺成功率和结石清除率均显著高于对照组(P<0.05),穿刺通道单通道完成例数多于对照组(P<0.05),并发症发生率显著低于对照组(P<0.05).结论 CTU在经皮肾镜取石术中能够提高手术效率,减少术中出血量和术后并发症,促进患者早日康复,具有重要的临床应用价值.%Objective To investigate the value of CT urography (CTU) in percutaneous nephrolithotomy (PCNL). Method A total of 82 patients with nephrolithiasis or ureteral calculi who were treated in our hospital from June 2014 to June 2016 were selected as subjects. They were divided into observation group (40 cases) and control group (42 cases) by random number table method. Control group patients were treated with CT scan, and observation group patients were examined by 128 rows of CT images. The CTU images were obtained and subjected to image post-processing. After the success of the calyx with B-guided ultrasound, ultrasound/ballistic lithotripsy system had been used to broken stonescompletely, postoperative review of abdominal plain film had been examinated to understand the remaining stone. Result The operation time and length of stay in observation group were significantly shorter than control group (P < 0.05), the amount of bleeding and perfusate used in operation were significantly less than control group (P < 0.05), the success rate and stone clearance rate were significantly higher than control group (P < 0.05), the number of completion of single channel was more than that in control group (P < 0.05), the complication rate was significantly lower than that of control group (P < 0.05). Conclusion CTU in the PCNL can improve the efficiency of surgery, reduce intraoperative blood loss and postoperative complications, and promote early recovery of patients, has important clinical value.
