[Ureteropyelostomy for obstructed duplicated ureter an easy and reliable operation in infants].
OBJECTIVE
Ureteropyelostomy is one of the surgical options to treat obstructed duplicated ureter. We retrospectively analysed the results of this procedure in a group of young children with prenatal diagnosis.


METHODS
Between 1992 and 1996, 11 children underwent ureteropyelostomy for obstructed functioning duplicated ureter using the following procedures. 7 cases were revealed by prenatal ultrasound and 4 by acute pyelonephritis; an ureterocele was identified in 7 cases. The mean age at surgery was 6 months for the whole group (3-46 weeks), while in the subgroup of prenatal diagnosis, it was 8 weeks (3-9 weeks). The follow-up ranged from 6 months to 4 years.


RESULTS
There were no postoperative complications. None of the anastomoses needed revision, and the conserved segments maintained their functioning appearance, on follow-up. 3 children needed a subsequent ureterovesical reimplantation for urinary tract infections due to reflux in the lower segment ureter.


CONCLUSIONS
Ureteropyelostomy is of great interest for the management of the obstructed dilated upper pole ureter revealed by prenatal diagnosis. This specific group of children needs early management to avoid septic complications and ureteropyelostomy is an easy and reliable method at this young age.
