Uncomplicated hypospadias and anomalies of upper urinary tract. Need for screening?

In a series of 200 patients with uncomplicated hypospadias, 6 (3 per cent) had an anomaly of the upper urinary tract. However, even this low figure is an overestimate of the usefulness of the intravenous pyelogram as a screening procedure since none of the patients has had related symptoms and none has required treatment for his anomaly. The implication of this review is that the intravenous urogram is not a necessary part of the evaluation, for management purposes, of the asymptomatic patient with uncomplicated hypospadias. Occasionally, some interesting information may be obtained.
