Urinary tract anomalies in patients with hypospadias.

Fifty-five patients with hypospadias were reviewed. Intravenous urography was carried out on 80%. The incidence of upper urinary tract anomalies was 22%. This was independent of the severity of the hypospadias. Patients with hypospadias and undescended testis were reviewed as a separate group. The incidence of upper urinary tract anomaly here was 31%. Again, the incidence was not influenced by the severity of the hypospadias. None of the upper urinary tract anomalies required surgical intervention. It is concluded that routine IVU is not indicated in all cases of hypospadias.
