To determine the efficacy of balloon dilatation in the treatment of ureteral strictures and analyze the outcome according to its etiology.
77 ureteral dilatations were performed in 74 patients. Most of the strictures were postoperative sequelae and the other cases were due to chronic inflammatory conditions.
The overall success rate was 47%, partial improvement was achieved in 17% and the failure rate was 36%. In our series, the postoperative strictures responded slightly better to balloon dilatation than those arising from chronic inflammatory conditions.
Endourologic techniques based on the percutaneous methods of interventional radiology have reduced the usage of invasive conventional surgery in the treatment of strictures. Although the proportion of unsatisfactory results is not negligible, balloon dilatation should be the first treatment option for ureteral strictures because it is less invasive, carries a low morbidity and requires a shorter hospitalization. If the results are unsatisfactory, re-dilatation can be attempted or conventional open surgery can be performed.
确定球囊扩张术治疗输尿管狭窄的疗效，并根据病因分析其结果。
对74例患者进行了77次输尿管扩张术。大多数狭窄为术后后遗症，其他病例则由慢性炎症引起。
总体成功率为47%，部分改善率为17%，失败率为36%。在我们的系列研究中，术后狭窄对球囊扩张术的反应略优于慢性炎症引起的狭窄。
基于介入放射学经皮方法的腔内泌尿外科技术减少了侵入性传统手术在狭窄治疗中的使用。尽管不满意结果的比例不可忽视，但球囊扩张术应作为输尿管狭窄的首选治疗方法，因为它侵入性较小、发病率低且住院时间较短。如果结果不满意，可以尝试再次扩张或进行传统开放手术。
