Congenital midureteric stricture

الملخص EN

Congenital midureteric obstruction is a rare entity which can be caused by either ureteric valves or strictures.

We report our experience with four patients with midureteric obstruction due to stricture over a six-year period.

The condition needs to be differentiated from obstruction of the pelviureteric and vesicoureteric junctions.

Obstruction can be initially screened by ultrasound and confirmed by a radionuclide scan with furosemide challenge.

Retrograde ureteropyelography and / or intravenous urography may be required to define the level of the stricture.
