Summary During the last 10 years we have treated 24 newborn and young infants (27 ureters) in whom the diagnosis of primary obstructed megaureter was established by diuresis‐enhanced radionuclide renography and/or by antegrade pressure flow studies (Whitaker test). Temporary uretero‐cutaneostomy was performed immediately after diagnosis. After 1 year a second modified Whitaker test showed normal passage of the contrast medium into the bladder in 23 ureters. In only 4 ureters did obstruction persist and uretero‐cystoneostomy was performed. Uretero‐cystoneostomy was also performed on 8 ureters without obstruction but with persistent vesicoureteric reflux, ectopic ureter or diverticula. In 11 patients a temporary uretero‐cutaneostomy was closed without corrective surgery at the vesicoureteric junction. Temporary uretero‐cutaneostomy is a safe and effective therapy in primary obstructed megaureter in newborns. Spontaneous relief of obstruction appears to be possible in primary obstructed megaureter.
