Forty-six benign ureteric stenoses in 42 patients were cannulated anterogradely and dilated. In 37 cases, balloon dilatation was carried out followed by a temporary insertion of a ureteric stent. Seven long stenoses were treated by continuous stenting, with a double pigtail stent. In two patients surgery had to be performed following percutaneous catheterisation and dilatation. Seven restenoses were due to tumour recurrences and lymph node metastases; apart from this, the success rate of balloon dilatation was 63%. The patients were observed for one to 41 months with an average of 14 months. Uncomplicated traumatic stenoses and fistulae were successfully treated with only one exception. Prognostically unfavourable features were devascularized ureteric segments, advanced scarring and very long stenoses.
42例患者的46处良性输尿管狭窄接受了顺行插管和扩张治疗。37例进行了球囊扩张，随后临时置入输尿管支架。7处长段狭窄采用双猪尾支架持续支架置入治疗。2例患者在经皮导管插入术和扩张术后必须进行手术。7例再狭窄是由于肿瘤复发和淋巴结转移；除此之外，球囊扩张的成功率为63%。对患者进行了1至41个月的观察，平均为14个月。除1例例外，单纯性创伤性狭窄和瘘管均成功治愈。预后不良的特征是输尿管段血运障碍、严重瘢痕形成和极长段狭窄。
