目的探讨输尿管结石腔内分期治疗疗效。方法对21例输尿管结石,一次腔内碎石难以成功的患者采用分期治疗。结果 1例输尿管上段结石,因输尿管狭细,改开放手术,3例输尿管上段结石碎石过程中部分结石上移,均行ESWL治疗,无>0.4cm结石残留,随访12个月未见结石复发,均无输尿管穿孔、撕裂。腔内分期手术发现输尿管内径均有明显增宽,8.0-9.8F输尿管硬镜能到达结石部位或肾盂;输尿管被拉直,扭曲明显改善。结论输尿管结石腔内分期治疗减少强行治疗输尿管结石的并发症,疗效明显,值得推广。
Objective To investigate the efficacy of staging in the treatment of ureteral calculi. Methods 21 patients with ureteral calculi, an intraluminal lithotripsy difficult to succeed in patients with staged treatment. Results One case of upper ureteral calculi due to ureteral stricture was changed to open surgery, and some of the stones in the upper ureteral calculi in 3 cases were moved upward. All cases were treated with ESWL without residual stones> 0.4 cm. No recurrence of stones was observed after 12 months of follow-up , No ureter perforation, tear. Endometrial staging found significantly increased ureteral diameter, 8.0-9.8F ureteroscopy can reach the stone site or renal pelvis; ureteral was straightened, twisted significantly improved. Conclusions Ureteral calculi in the staging of the cavity to reduce the complication of ureteral calculi forced treatment, the effect is obvious, it is worth promoting.
