Often misdiagnosed as primary megaureter or pelviureteric junction obstruction, congenital ureteral stenosis and valves are the main causes of congenital ureteric obstruction. We report three consecutive cases of congenital ureteric strictures presenting with antenatally diagnosed hydronephrosis. Two of our cases had a contralateral multicystic dysplastic kidney. We discuss the aetiology, clinical presentation, diagnostic evaluation, surgical management, and operative results as well as present an overview of the international literature, highlighting the importance of early referral in cases of contralateral abnormality as well as the importance of performing a retrograde study to facilitate the diagnosis and choice of incision.

D006869	Hydronephrosis	Abnormal enlargement or swelling of a KIDNEY due to dilation of the KIDNEY CALICES and the KIDNEY PELVIS. It is often associated with obstruction of the URETER or chronic kidney diseases that prevents normal drainage of urine into the URINARY BLADDER.	Hydronephroses
D014517	Ureteral Obstruction	Blockage in any part of the URETER causing obstruction of urine flow from the kidney to the URINARY BLADDER. The obstruction may be congenital, acquired, unilateral, bilateral, complete, partial, acute, or chronic. Depending on the degree and duration of the obstruction, clinical features vary greatly such as HYDRONEPHROSIS and obstructive nephropathy.

D021782	Multicystic Dysplastic Kidney	A nongenetic defect due to malformation of the KIDNEY which appears as a bunch of grapes with multiple renal cysts but lacking the normal renal bean shape, and the collection drainage system. This condition can be detected in-utero with ULTRASONOGRAPHY.
