An enlarged prostatic utricle is often associated with hypospadias. To evaluate the relationship between the incidence of prostatic utricle and the degree of hypospadias, we performed retrograde urethrography and/or micturating cystourethrography on 280 patients with hypospadias. Prostatic utricles were demonstrated in 84 patients (27.5%) and the incidence increased according to the severity of hypospadias. The prostatic utricles were classified into four types from the standpoint of size and location of the opening of the utricle, and a direct relationship was demonstrated between the severity of hypospadias and increasing size of the prostatic utricle.
前列腺囊增大常与尿道下裂相关。为评估前列腺囊的发生率与尿道下裂程度之间的关系，我们对280例尿道下裂患者进行了逆行尿道造影和/或排尿性膀胱尿道造影。84例患者（27.5%）显示有前列腺囊，其发生率随尿道下裂的严重程度增加而升高。从前列腺囊开口的大小和位置角度，前列腺囊被分为四种类型，并且尿道下裂的严重程度与前列腺囊增大之间存在直接关系。
