尿道下裂与扩大的前列腺囊

目的　探讨尿道下裂患者扩大的前列腺囊发生率及对尿道成形术的影响与处理方法。　方法　通过体检、尿道造影、尿道膀胱镜检查对 52例尿道下裂患者扩大的前列腺囊的发病率及程度 ,单纯尿道下裂与同时合并扩大的前列腺囊患者尿道成形术后尿瘘发生率进行分析。　结果　 52例中合并扩大的前列腺囊 1 6例 ,占 31 %。阴茎头型 5例、阴茎型 8例、阴茎阴囊型 2 0例、会阴型 1 9例 ,合并扩大的前列腺囊分别为 0、1、6、9例 ,且随尿道下裂严重程度的增加级别增高。术后尿瘘发生率单纯尿道下裂为 1 8.2 % ,合并扩大的前列腺囊者为 4 6 .7%。　结论　随尿道下裂程度增加 ,扩大的前列腺囊发生率及程度增加 ,术后尿瘘发生率亦逐渐增加。

Hypospadias and enlarged prostatic utricle

Objective To investigate the incidence of prostatic utricle in hypospadias patients,and to assess the influence of enlarged prostatic utricle on ureteroplasty. Methods Physical examination,retrograde urethrography and urethrocystoscopy were performed for 52 in patients with hypospadias to investigate the incidence and degree of enlarged prostatic utricle and its relationship with the occurrence of fistula after urethroplasty. Results Prostatic utricle were demonstrated in 16 patients(31%).Of the 52 patients,the hypospadias was the glanstype in 5,peniletype in 8,peno scrotumtype in 20 and the perineumtype in 19.The incidence of enlarged prostatic utricle was 0/5,1/8,6/20 and 9/19 respectively.The occurrence of post operative fistula in simple hypospadias was 18.2%,and in the hypospadias complicated with enlarged prostatic utricle 46.7%. Conclusions The incidence and degree of enlarged prostatic utricle was increased according to the severity of hypospadias, and the occurrence of postoperative fistula was also increased as well.
