The association of anterior urethral valve (AUV) with posterior urethral valve (PUV) is rare. A 7-month-old infant was presented at a district hospital with episodes of acute pyelonephritis. He was treated medically and a voiding cystourethrogram (VCUG) confirmed bilateral vesico-urethral reflux. The presence of concomitant AUV and PUV was not recognized. He underwent several surgical procedures, which failed. He had reflux recurrence following two antireflux procedures. He had urinary retention after each operation, which was managed by vesicostomy and perineal urethrostomy. At the age of 3.5 years, he was referred to our paediatric urology clinic. Noticing the AUV and PUV in the past VCUG, the valves were fulgurated. Urodynamic study before and 3 months after valve ablation showed a high voiding pressure. VCUG 6 months following ablation showed no reflux, but several uroflowmetric studies showed a staccato and interrupted pattern. Empirical treatment with an alpha-blocker was started. One year after treatment, a repeat VCUG showed no reflux. Uroflowmetry and urodynamic studies returned to normal. The perineal urethrostomy was closed. The child was asymptomatic after 9 months of follow up.
前尿道瓣膜(AUV)与后尿道瓣膜(PUV)同时存在的情况较为罕见。一名7个月大的婴儿因急性肾盂肾炎发作被送往一家地区医院。他接受了药物治疗,排尿性膀胱尿道造影(VCUG)证实存在双侧膀胱输尿管反流。当时并未发现同时存在AUV和PUV。他接受了多次手术,但均告失败。两次抗反流手术后反流复发。每次手术后他都出现尿潴留,通过膀胱造瘘术和会阴尿道造口术进行处理。3.5岁时,他被转诊至我们的儿科泌尿外科诊所。通过查看之前的VCUG发现了AUV和PUV,遂对瓣膜进行了电灼治疗。瓣膜切除术前及术后3个月的尿动力学研究显示排尿压力较高。切除术后6个月的VCUG显示无反流,但多次尿流率研究显示为断续和中断的模式。开始使用α受体阻滞剂进行经验性治疗。治疗1年后,复查VCUG显示无反流。尿流率和尿动力学研究恢复正常。关闭了会阴尿道造口术。经过9个月的随访,患儿无症状。
