Antegrade pyelography in ureteric duplications with obstructed upper segments.
Percutaneous puncture under fluoroscopic control followed by antegrade pyelography was employed in three children, two of them neonates, suspected of having complete duplication of the ureter with obstructed upper segments on the basis of the excretory pyelographic and ultrasonographic findings. This simple, uncomplicated and definitive method confirmed the diagnosis and demonstrated the course, termination and effects of the dilated ectopic ureter.
