目的:观察斜仰卧位B超引导下大通道经皮肾镜取石术(PCNL)治疗肾铸型结石的临床疗效。方法:选取我院于2015年7月~2016年8月期间收治的200例肾铸型结石患者为研究对象,随机分为对照组(n=100)与研究组(n=100)。对照组采用俯卧位中、小通道(传统体位)PCNL治疗,研究组采用斜仰卧位B超引导下大通道PCNL治疗。比较两组手术建立通道时间、手术时间、术中出血量、Ⅰ期结石清除率、术后感染率、手术舒适度及并发症发生情况。结果:研究组手术建立通道时间、手术时间、术中出血量均低于对照组,差异有统计学意义(P<0.05);研究组Ⅰ期结石清除率、手术舒适度高于对照组,而术后感染率低于对照组,差异有统计学意义(P<0.05);研究组并发症发生率较对照组明显更低,差异有统计学意义(P<0.05)。结论:对肾铸型结石患者采用斜仰卧位B超引导下大通道经皮肾镜取石术治疗,可显著提高临床疗效,降低术后感染率,提高手术舒适度,减少并发症的发生,促进患者身体恢复,具有临床推广意义。
OBJECTIVE: To observe the clinical effect of percutaneous nephrolithotomy (PCNL) guided by supine B-guided ultrasonography in the treatment of renal calculi. Methods: A total of 200 patients with renal calculi treated in our hospital from July 2015 to August 2016 were randomly divided into control group (n = 100) and study group (n = 100). The control group was treated with PCNL in prone position and small channel (traditional position), and the study group was treated with PCNL guided by supine B-channel. The duration of operation, operation time, intraoperative blood loss, stage Ⅰ stone clearance rate, postoperative infection rate, operation comfort and complication were compared between the two groups. Results: The time of operation establishment, operation time and blood loss in study group were lower than those in control group (P <0.05). The stone clearance rate and operative comfort of study group Ⅰ were higher than that of control group The postoperative infection rate was lower than that of the control group, the difference was statistically significant (P <0.05). The incidence of complications in study group was significantly lower than that in control group (P <0.05). Conclusion: The treatment of renal cast stone by supine B-guided percutaneous nephrolithotomy can significantly improve the clinical efficacy, reduce the postoperative infection rate, improve the operation comfort, reduce the occurrence of complications, and promote Patients recovered, with clinical significance.
