尿道下裂分型及与外生殖系统畸形的关系

目的 探讨尿道下裂分型及与合并外生殖系统畸形的相关性.方法 回顾性分析2000年1月至2009年10月收治的632例尿道下裂患者资料,分别统计各型尿道下裂的比例及合并外生殖系统畸形的比例,采用精确概率法及Spearman秩相关分析进行统计学处理.结果 632例尿道下裂患者中,轻度尿道下裂80例(12.6%),中度144例(22.8%),重度273例(43.2%),特重度135例(21.4%).发生阴茎阴囊转位、隐睾、鞘膜积液、隐匿型阴茎、假阴道等外生殖系统畸形共184例次,合并畸形157例,占24.8%.尿道下裂分型与总体畸形、阴茎阴囊转位、隐睾的发生具有统计学意义,并呈正相关;而尿道下裂分型与鞘膜积液的发生无统计学意义.结论 尿道下裂患者以中度以上者占多数,以合并阴茎阴囊转位者最常见,其次为隐睾、鞘膜积液;尿道下裂越严重,合并外生殖系统畸形的概率及发生阴茎阴囊转位、隐睾的概率越高.

Abstract：

Objective To investigate the correlation of the type of hypospadias and external genital system malformations. Methods From Jan 2000 to Oct 2009, the data of 632 patients diagnosed with hypospadias was analyzed retrospectively. The proportion of all types of hypospadias and the frequency of external genital system malformations were statistically analyzed. Results Among all cases, 12.6% exhibited mild hypospadias, 22. 8% moderate, 43. 2% severe and 21.4% had extremely severe hypospadias. One hundred and eighty-four cases with external genital system malformations were classified into penoscrotal transposition, cryptorchidism, hydrocele of tunica vaginalis,concealed penis and pseudovagina. The probability was about 24.8% (157 cases) of 632 patients with hypospadias. There was significant difference and a positive correlation among the type of hypospadias with total malformations, penoscrotal transposition, cryptorchidism. Conclusions In this patient cohort, moderate and severe hypospadias accounted for the majority of hypospadias. Penoscrotal transposition was the most frequent external genital system malformation in hypospadias, followed by cryptorchidism and hydrocele of tunics vaginalis. More severe hypospadias is accompanied with a higher probability of the external genital system malformations, penoscrotal transposition and cryptorchidism.
