Abstract: 【Abstract】〓Objective〓To observe the effect of flexible ureteroscopy combined with minimally invasive percutaneous nephroscope in the treatment of renal staghorn calculi. Methods〓Twenty-six cases with renal staghorn calculus underwent the treatment of flexible ureteroscopy and minimally invasive percutaneous nephroscope (F16-20). The clinical data, including operation time and the rate of residual stones were recorded and analyzed. Results〓All the operation was completed successfully. There was no occurrence of serious complications such as ureteral perforation,pneumothorax, intestinal damage and hemorrhage. KUB showed that the stone clearance rate reached 81% (21/26) in the first stage of operation. The operation time was 60-150 min, 95±13 min on average. The second stage of operation was performed 5 to 7 days postoperatively. The stone clearance rate was 92.3%(24/26) in the two stages of operation. The operation time was 30-150 min, 45±11 min on average. Two residual calculi patients were performed with extracorporeal shock wave lithotripsy (ESWL) in one month after operation and the residual stones were discharged. The hospitalization time was 5-12 d, 6.5 d on average. Conclusion〓Flexible ureteroscope operation combined with minimally invasive percutaneous nephroscope is a good choice for treatment of complicated renal calculi.

摘要： 【摘要】〓目的〓报告输尿管软镜联合微创经皮肾镜治疗鹿角形肾结石的疗效和治疗经验。方法〓收集鹿角形肾结石患者26例,术前常规检查双肾多排CT平扫加增强扫描,三维重建。行输尿管软镜联合微创经皮肾镜治疗。统计手术时间,结石残余率。结果〓所有手术顺利完成,无输尿管穿孔、气胸、肠道损伤及大出血等严重并发症发生。术后复查KUB示一期手术结石取净率为81%(21/26),手术时间60~150 min,平均95±13 min。7例结石残余,术后第5~7天行二期手术,结石取净率为92.3%(24/26),手术时间30~150 min,平均45±11 min。2例结石残留患者行术后1月行体外冲击波碎石治疗后完全排出。术后住院5~12 d,平均6.5 d。结论〓输尿管软镜联合微创经皮肾镜治疗复杂肾结石安全、有效。
