Developmental anomalies associated with hypospadias.

We reviewed 272 patients with hypospadias who were treated surgically to survey the complicated anomalies in these patients. Urogenital anomalies were recognized in 40 per cent of the 272 cases and extra-urogenital anomalies were noted in 9.2 per cent. Undescended testis was the most frequently seen anomaly, having been noted in 13.2 per cent of the 272 cases. The incidence of male vagina or utriculus masculinus was 11.8 per cent, prepenile scrotum 7.7 per cent and hypoplasia of the testis 6.6 per cent. Each of these 4 anomalies associated with hypospadias increased in incidence in proportion to the severity of the penile deformity. The necessity of systemic urological and hormonal examinations was emphasized, especially in cases of severe hypospadias.
