目的:探讨不切开输尿管口,直接输尿管镜下钬激光碎石治疗输尿管膀胱壁段结石的手术技巧。方法:选取输尿管膀胱壁段结石患者32例,根据结石的分类,不切开输尿管口,采取盲法结合直视下输尿管镜钬激光碎石,术后留置双J管2～4周,3～6个月后复查B超、CT或者IVU。结果:32例患者均成功粉碎结石,其中1例发生输尿管黏膜轻微撕脱,1例发生输尿管黏膜下假道。留置双J管后随访,复查正常。结论:不切开输尿管口,采取盲法结合直视下输尿管镜钬激光碎石治疗输尿管膀胱壁段结石是一种安全有效的微创治疗。
Objective: To investigate the surgical technique of ureteroscopic ureteroscopic holmium laser lithotripsy without ureteropelvic opening. Methods: Thirty-two patients with ureteral calculi were included in the study. According to the classification of stones, ureteropelvic was not incised, ureteroscopic holmium laser lithotripsy under direct vision was performed, and double J tube was placed for 2 to 4 weeks, After 6 months to review the B-, CT or IVU. Results: Thirty-two patients were successfully crushed stones, one case of ureteral mucosa slightly avulsion, and one case of ureteral submucosal false. Double J tube after ligation, review normal. Conclusion: Untreated urethral orifice, combined with ureteroscopic ureteroscopic holmium laser lithotripsy under direct vision is a safe and effective minimally invasive treatment of ureteral wall segment stones.
