To review cases of congenital ureteric stenosis treated in the period between 1999 and 2007. We propose to analyze the type of presentation, management and results.

Material and methods

We report 17 children aged 20 days to 8 years with obstructive uropathy due to congenital stenosis of the ureter at one or more levels. This condition could be mistaken for the more common pelviureteric junction obstruction (PUJO) or primary megaureter, but it is a distinct and more serious anomaly. 13 of the 17 children had one or more associated anomalies, the most significant of which was a contralateral multicystic dysplastic kidney. Other associated anomalies included PUJO, megacalyx, vesicoureteric reflux, urogenital sinus, duplicate vagina, anorectal malformation and agenesis of the bladder. 16 children were symptomatic at presentation, with uremia (serum creatinine >1 mg/dl) in 5, while 1 was diagnosed antenatally. The correct preoperative diagnosis was made in only three children. Reconstruction included ureteroureteral anastomosis, ureteric reimplantation or ureteral substitution.


There is follow up for 15 of the 17 patients. Length of follow up ranges from 1 to 7 years (average 2.7 years). There was satisfactory urinary drainage established in all 17 cases and uremia has resolved 3 of the 5 children. The children with solitary functioning kidney are at risk of uremia in later life.


Congenital ureteric stenosis is a rare condition, but distinct anomaly with possible grave consequence and has been distinguished from other causes of congenital ureteric obstruction.
