title: [Caudal migration of the verumontanum and enlargement of the utricle in hypospadias].
abstract: Hypospadias is one of the morphological and functional alterations of the internal urogenital organs under the influence of androgen deficiency. In the time period 1974-1998 a total of 823 cases of hypospadias were surgically treated and the findings of the preoperative X-ray diagnostics with micturating cystourethrogram (MCU) and urethrocystogram (UCG) as well as urethrocystoscopy were analyzed. A caudal migration of the verumontanum could be detected in 55% of cases with hypospadias (453/823) and in 79% (322/403) of middle grade (penoscrotal) and high grade (scrotoperineal) cases of hypospadias. Enlargement of the utricle was present in 31.5% (259/823) cases of hypospadias and in 46.2% (186/423) of middle grade (penoscrotal) and high grade (scrotoperineal) cases of hypospadias.
