RESUMO
vesicoureteral reflux [VUR] is a fairly common disorder in infants. Children with VUR frequently demonstrate various gastrointestinal symptoms such as nausea, vomiting, loss of appetite and weight loss. These symptoms similarly may present in gastrointestinal diseases like gastroesophageal reflux [GER]. It is thought that some children are prone to have both conditions. This study was done to investigate the coexistence of VUR and GER in infants with urinary tract infection. This cross sectional study was performed on all infants under 12 months old with urinary tract infection who were admitted to Tehran Mofid hospital during one year [Nov 2007-Nov 2008]. In all of these infants, we performed voiding cystoureterography [VCUG] to investigate VUR and gastric sonography to assess GER. We used questionnaires to assess our variables. Collected data were analized by SPSS ver 13 software and frequency tables and independent T test and Chi-square. Among 43 infants with urinary tract infection who performed VCUG and gastric sonography, the prevalence of VUR was 55.8% and the prevalence of GER was 48.8%. The coexistence of both conditions was found in 39.5%. No significant difference was found between coexistence of these disorders with presenting symptoms, sex, weight, type of microorganisms, type of feeding and grade of reflux. The coexistence of VUR and GER is common. Therefore in an infant with VUR who remains symptomatic in spite of treatment, the possibility of GER should be considered and evaluation for diagnosis and treatment of GER might be done
