目的探讨微创经皮肾镜碎石术(MCNL)与经输尿管镜钬激光碎石(URL)治疗输尿管上段结石的临床疗效。方法分别采用MCNL术和URL术治疗120例输尿管上段结石患者,观察对比两种术式的临床疗效。结果 URL组手术时间、术中出血量、导尿管拔出时间及术后住院时间明显优于MCNL组;而术后结石清除率MCNL组优于URL组,两组比较差异有统计学意义(P<0.05)。两组术后并发症发生率比较差异无统计学意义(P>0.05)。结论对较大结石和近肾盂输尿管交界部位的输尿管上段结石患者建议采用MCNL术式治疗。
Objective To investigate the clinical effects of minimally invasive percutaneous nephrolithotomy (MCNL) and ureteroscopic holmium laser lithotripsy (URL) in the treatment of upper ureteral calculi. Methods A total of 120 patients with upper ureteral calculi undergoing MCNL and URL surgery were enrolled in this study. The clinical effects of the two procedures were compared. Results The operation time, intraoperative blood loss, catheter pull-out time and postoperative hospital stay in the URL group were significantly better than those in the MCNL group. The stone clearance rate in the MCNL group was better than that in the URL group. There was significant difference between the two groups P <0.05). There was no significant difference in the incidence of postoperative complications between the two groups (P> 0.05). Conclusion MCNL is the recommended treatment for patients with upper ureteral calculi at the junction of the larger stones and the proximal ureteropelvic junction.
