The purpose of the study was to analyze treatment approaches in children with malformations of urinary system. The retrospective study comprised 557 children (196 boys and 361 girls) aged 1-18 years with malformations of urinary system hospitalized in 2000-2007 in the Department of Pediatric Nephrology, University Children's Hospital, Lublin. Primary and secondary vesicoureteral reflux (269 children), ureteral obstruction (102 children), urethral obstruction (91 children) and renal duplication (83 children) were the most common malformations observed. In 26 children, multiple urinary system malformations were diagnosed. 332 children required surgery including 113 with vesicoureteral reflux. However, in the majority of children with vesicoureteral reflux, on an average 18-month pharmacologic treatment resulted in complete recovery.
