To analyse the long-term success of retrograde balloon dilatation (RBD) of pelvi-ureteric junction obstruction (PUJO).
The records of 58 adult patients (mean age 48 years, range 18-94) who had RBD between 1990 and 2001 were reviewed retrospectively. All symptomatic patients were included and assessed by dynamic renography. Success was judged as a symptomatic and/or functional improvement. Recurrence of symptoms was recorded and any evidence of deterioration of function despite improved symptoms. Complications were also recorded.
In all, 44 (76%) patients were asymptomatic after RBD. There was no relationship between symptomatic change and renographic improvement; some patients who were rendered pain-free had either no improvement or even deterioration in their split renal function. Conversely, some patients who had a demonstrable improvement in their renal function continued to be symptomatic. However, a long-term follow-up (mean 6.1 years) of nine patients who were symptomatically improved showed good maintenance of split renal function.
RBD is an effective treatment for PUJO and its success is maintained in the long term.
分析肾盂输尿管连接处梗阻（PUJO）逆行球囊扩张术（RBD）的长期疗效。
回顾性分析1990年至2001年间接受RBD治疗的58例成年患者（平均年龄48岁，范围18 - 94岁）的病历。纳入所有有症状的患者，并通过动态肾图进行评估。成功定义为症状和/或功能改善。记录症状复发情况以及尽管症状改善但功能恶化的任何证据。同时记录并发症情况。
总体而言，44例（76%）患者在RBD术后无症状。症状变化与肾图改善之间无相关性；一些疼痛缓解的患者分肾功能无改善甚至恶化。相反，一些分肾功能有明显改善的患者仍有症状。然而，对9例症状改善患者进行的长期随访（平均6.1年）显示分肾功能维持良好。
RBD是治疗PUJO的有效方法，且长期疗效良好。
