目的探讨输尿管软镜下钬激光碎石术治疗肾结石的疗效。方法肾结石患者15例,非明显输尿管硬镜及经皮造瘘肾镜手术适应症,采用输尿管硬镜镜体扩张后留置输尿管扩张鞘,再置入输尿管软镜,寻及结石以钬激光击碎结石。结果输尿管软镜下钬激光碎石治疗肾结石15例,一次进镜成功14例,2次进镜成功1例,单次碎石均成功,手术时间平均45min(30～80min),住院时间平均5d(3～7d),无脓肾、输尿管穿孔等并发症。结论输尿管软镜下钬激光碎石术治疗肾结石安全、有效、并发症少,是对其他碎石治疗办法的补充。
Objective To evaluate the efficacy of ureteroscopic holmium laser lithotripsy in the treatment of renal calculus. Methods Fifteen patients with nephrolithiasis, non-obvious indications of ureteroscopic and percutaneous nephrolithotomy were treated with ureteroscopic dilatation of ureteral dilatation sheath and ureteroscopic soft-lens placement. The stones were treated with holmium laser Crushed stones. Results of ureteroscopic holmium laser lithotripsy in 15 cases of renal calculi, a successful 14 cases into the mirror, two successfully into the mirror in 1 case, a single gravel were successful, the average operation time 45min (30 ~ 80min), the average length of stay 5d (3 ~ 7d), no pus kidney, ureter perforation and other complications. Conclusion ureteroscopic holmium laser lithotripsy for the treatment of renal stones is safe, effective and has fewer complications. It is a supplement to other lithotripsy.
