目的 评价逆行球囊导管扩张输尿管狭窄的治疗效果。方法 对 16例输尿管狭窄的病人 (8例吻合口狭窄 ,5例炎性狭窄 ,3例先天性狭窄 )进行了 2 2次扩张 ,其中 6例一次扩张无效后作了第二次扩张。分别在术后 1月、6月进行静脉肾盂造影 (IVP)和肾功能复查。结果 IVP显示病人肾盂积水状况改善表明有效 ,16例病人术后 1月、6月的有效率均是 6 2 % (10 / 16 )。 6例有症状的病人中 5例半年后恢复正常 ,5例血清尿素氮 (NPN)水平升高的病人中 4例半年后恢复正常。所有病人的扩张技术均成功。结论 逆行球囊导管扩张输尿管狭窄的技术是成功的 ,它作为输尿管狭窄外科治疗的一种替代方法是可行的。
Objective To evaluate the therapeutic effect of retrograde balloon catheter dilation ureteral stricture. Methods Twenty-six patients with ureteral stricture (8 anastomotic stenosis, 5 inflammatory stenosis and 3 congenital stenosis) underwent 2 2 dilations. Among them, 6 dilated without expansion. Intravenous pyelography (IVP) and renal function were performed in January and June respectively. Results IVP showed that the improvement of hydronephrosis in patients showed that effective, 16 patients in January and June after the effective rate was 62% (10/16). Five of the six symptomatic patients returned to normal six months later, and four of the five patients with elevated serum levels of urea nitrogen (NPN) returned to normal six months later. All patients had successful dilatation techniques. Conclusions The technique of retrograde balloon catheter for dilatation of ureteral stricture is successful. It is feasible as an alternative to surgical treatment of ureteral stricture.
