title: [Obstructive and non-obstructive ureteral valves in early infancy (author's transl)].
abstract: Cork-screw formation or kinking of the subpelvine ureter, mostly bilateral, are common findings in the routine urogram of the infant without functional effects on the urine flow. Otherwise true ureteral valves with obstructive effect, a congenital malformation in early infancy, are relatively rare. We present two cases with recurrent infection of the urinary tract and clearly visible subpelvine ureteral valves in the urogram. In one patient an obstructive pyeloectasia could not be demonstrated in spite of significant multiple valves.
