We report the case of a 6-year-old boy who presented with lower urinary tract obstruction and chronic renal impairment due to a delayed diagnosis of isolated CAUD. The diagnosis was eventually made by voiding cystourethrography, which revealed a large anterior diverticulum. This case illustrates a rare late presentation of CAUD with significant renal dysfunction, highlighting a crucial diagnostic pitfall. Clinicians should actively consider and investigate for anterior urethral diverticulum in any male child presenting with unexplained renal insufficiency or voiding symptoms, as early detection is essential to prevent irreversible upper urinary tract damage.
我们报告了一名6岁男孩的病例，该男孩因孤立性先天性后尿道瓣膜症（CAUD）诊断延迟而出现下尿路梗阻和慢性肾功能损害。最终通过排尿性膀胱尿道造影确诊，结果显示有一个大的前憩室。该病例说明了CAUD罕见的晚期表现并伴有严重肾功能障碍，突出了一个关键的诊断陷阱。对于任何出现不明原因肾功能不全或排尿症状的男童，临床医生应积极考虑并检查是否存在前尿道憩室，因为早期发现对于预防不可逆的上尿路损害至关重要。
