Excretory urography as a screening method for abnormalities of the upper urinary tract in asymptomatic boys with...

Congenital dystopic testicles frequently occur jointly with abnormalities of the kidneys and the system of draining urinary ducts. A series of 100 asymptomatic boys has been studied by intravenous excretory urography after having undergone orchiopexy for retained testes. All children were clinically non-suspect and there was no history of urinary tract malformation. The investigations brought to light 7 major and 9 minor abnormalities. However, the authors do not recommend the use of intravenous urography as a routine procedure in all children with undescended testicles. The indications of the diagnostic procedure must be limited.
