MORPHOROGICAL INVESTIGATION OF VAGINAL REST (REMNANT OF VAGINA) IN PATIENTS WITH HYPOSPADIAS AND MALE HERMAPHRODISM

Abstract

61 cases with hypospadias and 28 cases with male hermaphrodism have been studied radiographically in order to evaluate the significance of vaginal rest. We have compared the incidence and the size of vaginal rest and localization of vaginal orifice in these patients.
There was a vaginal rest in 25 per cent of the glandular, 29 per cent of the penile, 43 per cent of the penoscrotal, 71 per cent of the scrotal and 100 per cent of the perineal hypospadias, with over all incidence of 48 per cent.
The incidence of undescended testes associated with hypospadias was 41 per cent and that with male hermaphrodism 85.7 per cent.
Abnormal findings of excretory urography were observed 13.1 per cent with hypospadias and 21.4 per cent with male hermaphrodism.
To compare the size of the vaginal rest in each case, we express the size of vaginal rest as the relative length to the posterior urethra. In patients with hypospadias, the size was below two-thirds of the posterior urethra. In all male hermaphrodism it was greater than two-third of the posterior urethra.
In hypospadias the vaginal orifice opened at the normal position of the Vermontanum in the posterior urethra, but in male hermaphrodism, its orifice opened at lower position, close to the external sphincter.
Thus, hypospadias accompanied by vaginal rest was characterized by that its size is smaller than two-thirds of the posterior urethra and its orifice is located at normal Vermontanum in the posterior urethra.
