Abstract：
BACKGROUND: A prostatic utricle is a congenital saccular indentation in the prostatic urethra and frequently enlarged in hypospadias patients. We present a case of urinary retention associated with a mildly enlarged utricle.
METHODS: A 20-year-old male, who underwent multiple repair procedures for hypospadias during childhood, was referred to us for dysuria. Retrograde urethrogram, voiding cystourethrogram, and cystoscopy results revealed only a mildly enlarged prostatic utricle, with no apparent lower urinary tract obstruction or urethral valves. A meatotomy was performed under suspicion of meatal stenosis, though urinary retention occurred following that procedure. Transrectal ultrasonography revealed flapping of the prostatic urethra floor over the utricle. Transurethral unroofing of the utricle relieved the dysuria.
CONCLUSIONS: A mildly enlarged prostatic utricle can cause dysuria. To the best of our knowledge, no case similar to the present has been previously reported.

摘要：
背景：前列腺囊是一种先天性前列腺尿道囊状凹陷，在尿道下裂患者中经常增大。我们介绍了一例与轻度增大的囊相关的尿潴留。
方法：一名20岁男性，他们在童年时期接受了多次尿道下裂修复手术，因为排尿困难被推荐给我们.逆行尿道造影,排尿膀胱尿道图，膀胱镜检查结果显示只有轻度增大的前列腺囊，无明显下尿路梗阻或尿道瓣膜。在怀疑肉孔狭窄的情况下进行了肉孔切开术，尽管在该程序之后发生了尿潴留。经直肠超声检查显示前列腺尿道地板拍打。经尿道去顶骨缓解了排尿困难。
结论：前列腺囊轻度增大可引起排尿困难。据我们所知,以前没有报告过类似的病例。
