[Vesicoureteral refluxes in children during the first two years of life].

Ninety-six children with vesicoureteral reflux (VUR) diagnosed by age 2 were studied. The most common indication for radiological visualization of the urinary tract was a urinary tract infection (UTI). Among 143 cases of VUR, 51% were unilateral and 49% were bilateral. Other urinary tract abnormalities coexisted with VUR in 14.6% of children. Abnormal USG result was found in 24% of children, including only 13.4% with VUR and other urinary tract abnormalities. Conservative treatment was chosen in 126 (88%) cases of VUR in 87.5% of children. Follow-up voiding cystourethrography was performed in 60.7% of children. Conservative treatment was successful in 68.6% of children. VUR disappeared in 70.9% of cases after mean follow-up of 13.7 months (including 76.2% cases of VUR grade II, 54.5% cases of VUR grade III and 50% cases of VUR grade I). Recurrent UTI and lack of improvement after conservative treatment were indications for surgical treatment in 9.8% of children. Recurrent UTI were observed in 15.6% of children (including 16.7% among those treated conservatively and 8.3% among those treated surgically) and their course was febrile in most cases.
