目的探讨输尿管镜下Teflon锥形头扩张器联合气压弹道碎石处理输尿管下段狭窄伴结石的临床效果。方法回顾性分析经尿道输尿管镜下Teflon锥形头扩张器联合气压弹道碎石治疗输尿管下段狭窄伴结石28例患者的临床资料。结果 28例患者中有1例术中经Teflon锥形头扩张器扩张处理狭窄后,进镜发现结石上移,予以留置F6双J管,术后结合体外冲击波碎石处理;其余患者均顺利完成一期同时处理输尿管狭窄及结石。手术时间20-38min。19例患者术后有轻微肉眼血尿或发热,所有患者无输尿管穿孔、脱套、撕裂等严重并发症发生。影像学随访检查显示肾盂积水均消失或明显减轻。结论输尿管镜下Teflon锥形头扩张器联合气压弹道碎石处理输尿管下段狭窄伴结石具有操作简单、效果确切、并发症少等优点。
Objective To investigate the clinical effect of ureteroscopic Teflon conical head dilator combined with pneumatic lithotripsy in the treatment of lower ureteral stenosis and calculi. Methods The clinical data of 28 patients with ureteral stenosis and ureteral calculi underwent ureteroscopic Teflon conical head dilator combined with pneumatic lithotripsy were retrospectively analyzed. Results One of the 28 patients was treated with Teflon conical dilator to expand the stenosis. The stones were found to go up in the mirror, and the double J tube of F6 was placed. Combined with extracorporeal shock wave lithotripsy, the rest of the patients were successfully completed A simultaneous treatment of ureteral stricture and stones. Surgery time 20-38min. Nineteen patients had mild gross hematuria or fever after operation. All patients had no serious complications such as ureter perforation, debridement and tearing. Imaging follow-up examination showed hydronephrosis disappeared or significantly reduced. Conclusions Ureteroscopic Teflon conical head dilator combined with pneumatic lithotripsy in the treatment of lower ureteral stricture associated with calculi has the advantages of simple operation, exact effect and few complications.
