摘要
目的探讨经尿道输尿管扩张治疗输尿管下段狭窄的临床效果。方法采用经尿道输尿管扩张治疗输尿管下段狭窄118例。男68例,女50例,平均年龄38岁。狭窄段长度0.5～2.0 cm。结果 118例均顺利通过输尿管扩张导丝,狭窄段扩张成功。随访6～30个月,平均13个月。一次扩张成功102例(86.4%),B超提示肾盂积水均消失或明显减轻,CTU示狭窄段通畅;其中2例先天性巨输尿管症术后取支架后狭窄复发,肾盂积水无明显改善,经再次扩张和置入双"J"管后,肾积水减轻,狭窄段较前通畅。所有手术无输尿管穿孔、脱套、撕裂等严重并发症发生。结论经尿道输尿管扩张治疗输尿管下段狭窄具有操作简单、效果可靠、并发症少、体表无伤口,可重复治疗及住院时间短等优点。
Objective To investigate the clinical effect of the transurethral ureteral dilatation in the treatment of lower ureter stenosis.Methodsl 18 patients with lower ureter stenosis were treated by transurethral ureteral dilatation.There were 68 male and 50 female with the mean age of 38 years old.The lengths of the narrow segments were 0.5～2.0 cm.Results In all of the 118 cases,the guide wire of the ureteral dilator passed through the narrow segment smoothly.All the patients were successfully dilated.Follow-up lasted for 6～30 months,average 13 months.102 cases were successfully dilated by single operation(86.4%).B ultrasonic showed that the hydronephrosis disappeared or reduced significantly.CTU showed the narrow segment is unobstructed.2 cases with Congenital Megaureter turned up restenosis after the double J stents were removed, the Hydronephrosis was not improved significantly neither.After dilatation and putting into double'J'tubes for another time,the Hydronephrosis was alleviated,the narrow segments were more clear than before.There is no ureteral perforation,degloving injury,tear and any other severe complications in all of the operations. Conclusions The advantages of transurethral ureteral dilatation in the treatment of lower ureter stenosis include simplicity of operation,reliable efficacy,no visible surgical incision in body surface,repeatedly performable process and short hospital stay.
