Evaluation of dilatation as a minimally invasive technique for the treatment of ureteric strictures.
We evaluated this technique in 16 patients with ureteric and secondary pelviureteric junction strictures from June 1998. Of these, 7 were men and 9 were women. The age range was from 14 to 40 years.
Balloon dilatation was successful in 69% of patients. Strictures secondary to previous surgery had nearly 100% success. Of the 8 cases diagnosed as genitourinary tuberculosis, success rate was 50%.
Factors affecting success of balloon dilatation are: a) age of the stricture b) length of the stricture and c) etiology of the stricture. In a select group of patients with fresh post-operative or post-inflammatory strictures, balloon dilatation may be an attractive alternative to surgery.
评估扩张术作为治疗输尿管狭窄的一种微创技术。
自1998年6月起，我们对16例输尿管及继发性肾盂输尿管连接处狭窄患者采用了该技术。其中，男性7例，女性9例。年龄范围为14至40岁。
69%的患者球囊扩张术成功。既往手术所致狭窄的成功率近100%。在8例诊断为泌尿生殖系统结核的病例中，成功率为50%。
影响球囊扩张术成功的因素有：a）狭窄的时间；b）狭窄的长度；c）狭窄的病因。对于一组特定的术后或炎症后新鲜狭窄患者，球囊扩张术可能是一种有吸引力的手术替代方案。
