To evaluate the incidence and significance of an enlarged prostatic utricle in hypospadiac patients without underlying intersex 44 patients with the meatus located in the perineum, penoscrotal junction or proximal two-thirds of the penis were evaluated with cystourethroscopy immediately before the operation. There was an abnormally enlarged utricle in 57% of the perineal, 10% of the penoscrotal and none of penile hypospadiacs, for an over-all incidence of 14%. Concurrent analysis of a series of phenotypic male patients with hypospadias and intersex revealed a high incidence of enlarged utricle or the presence of a vagina masculinus. Utricular enlargement in itself does not indicate intersexuality but careful cystoscopic examination of its vault needs to be undertaken, searching for a cervix. An enlarged utricle can be a manifestation of delayed müllerian duct regression or decreased androgenic stimulation of the urogenital sinus.
为评估在无潜在两性畸形的尿道下裂患者中前列腺囊增大的发生率及意义，对44例尿道口位于会阴、阴茎阴囊交界处或阴茎近端三分之二处的患者在手术前立即进行膀胱尿道镜检查。会阴型尿道下裂患者中57%存在前列腺囊异常增大，阴茎阴囊型为10%，阴茎型尿道下裂患者中无增大情况，总体发生率为14%。对一系列患有尿道下裂和两性畸形的表型男性患者进行的同时分析显示，前列腺囊增大或存在男性阴道的发生率很高。前列腺囊增大本身并不表明存在两性畸形，但需要对其穹窿进行仔细的膀胱镜检查，寻找宫颈。前列腺囊增大可能是苗勒管退化延迟或泌尿生殖窦雄激素刺激减少的表现。
