Posterior urethral valves (PUVs) are the most common cause of congenital urethral obstruction. However, the diagnosis of a PUV is sometimes difficult. A 13-year-old Japanese boy and his mother visited our hospital, and his mother complained that he frequently strained to void although he had no complaint. Uroflowmetry revealed a plateau-shaped curve and a voiding cystourethrography (VCUG) revealed a PUV. Thus, we performed a transurethral incision of the PUV, and his voiding status improved. Because some patients with mild PUV may not notice their dysuria, we believe that VCUG should be performed without hesitation when a urethral lesion is suspected.
后尿道瓣膜（PUV）是先天性尿道梗阻最常见的原因。然而，PUV的诊断有时很困难。一名13岁的日本男孩和他的母亲前来我院就诊，他的母亲抱怨说，尽管他没有不适，但经常用力排尿。尿流率测定显示为平台状曲线，排尿性膀胱尿道造影（VCUG）显示存在PUV。因此，我们对PUV进行了经尿道切开术，他的排尿状况得到了改善。由于一些轻度PUV患者可能没有注意到排尿困难，我们认为当怀疑有尿道病变时，应毫不犹豫地进行VCUG检查。
