Infundibulopelvic dysgenesis is a rare condition characterized by congenital malformation of the pelvicalyceal system. We present the case of an 18-year-old boy with chronic intermittent right flank pain and cystic dilation with parenchymal thinning on ultrasonography. The left kidney was normal. The patient denied dysuria, constipation, and history of UTIs or renal calculi. Cystoscopy with retrograde pyelogram showed marked stenosis of the right pelvicalyceal system and anatomy unfavorable to stenting. The patient's symptoms were unresponsive to conservative management. Reconstruction of the right collecting system was unsuccessful and a simple nephrectomy was performed, which led to complete resolution of his symptoms.
肾盂漏斗发育不全是一种罕见的疾病，其特征为肾盂肾盏系统的先天性畸形。我们报告一例18岁男性患者，其有慢性间歇性右腰腹痛，超声检查显示囊性扩张伴实质变薄。左肾正常。患者否认排尿困难、便秘以及尿路感染或肾结石病史。膀胱镜检查及逆行肾盂造影显示右肾盂肾盏系统明显狭窄，且解剖结构不利于支架置入。患者症状对保守治疗无反应。右集合系统重建未成功，遂行单纯肾切除术，术后患者症状完全缓解。
