The clinical presentation of hypospadias has three characteristics: 1. The ectopic urethral orifice may open anywhere from the proximal end of the normal urethra to the perineal urethra. Some urethral orifices have mild stenosis with a mucosa-like shallow groove at their distal end. A thin urethral fold is visible in cases of spongiotic agenesis. 2, penile recurvature, according to the angle between the head of the penis and the longitudinal axis of the serving stem body, the penile recurvature can be classified as mild: less than 15°; moderate: 15-35°; severe: greater than 35°. The latter two have difficulty in sexual intercourse in adulthood. 3, abnormal distribution of foreskin, the ventral foreskin of the head of the penis is V-shaped defect because it fails to fuse in the midline, the foreskin tether is absent, and all the foreskin is turned to the dorsal side of the head of the penis in a cap-like accumulation. According to the urethral location hypospadias is divided into four types: Ⅰ° penile head, coronal groove type accounts for about 20%; Ⅱ° penile body type accounts for about 44%; Ⅲ° penile scrotum type accounts for about 30%; Ⅳ° perineum type accounts for about 6%.
