The role of routine radiographic screening of boys with hypospadias: a prospective study.

One hundred fifty-three asymptomatic boys with hypospadias were screened routinely by intravenous pyelography and voiding cystourethrography. Urinary tract abnormalities were found in 23.53%. Significant abnormalities were found in 11% on initial examination, and on follow-up, a further 4.5% required later surgery. The overall incidence of surgical interference, not including hypospadias repair, was 11.76%. Thus, routine urinary tract radiological screening in boys with hypospadias is recommended.
