Evaluation of Urinary Tract Infection in Children With Gastroenteritis

Urinary tract infection (UTI) is the second most common bacterial infection in infancy and childhood with peaking in infancy and toilet training. The current study aimed to investigate UTI in patients with diarrhea. This case-control study was conducted on 200 participants, 100 were patients with acute gastroenteritis and the other 100 were controls who referred to the clinic for routine checkup. UTI was defined as two positive urine cultures with > 105 cfu/mL. If white blood cells were more than 10/mm3 in un-centrifuged urine it would be considered pyuria and more than one microorganism in 10 oil immersion fields as bacteriuria. Analysis was conducted using SPSS ver. 16 with application of chi-square test and 0.05 as significant levels. The distribution of these 200 children were 115 (57.5%) and 85 (42.5%) for females and males respectively. The gender and age distribution in case and control groups showed non-significant association. In urine culture it was observed that 27 individuals were positive and there were seven healthy children. The number of children with positive urine culture was higher than that of their counterparts significantly (P = 0.0001). Relationship between urine culture and age groups showed that the number of participants with positive urine culture was higher in children with age of two months to two years but it was not significant (P = 0.54). It was demonstrated that, considerable percentage of UTI existed in the gastroenteritis diseases. Early treatment of UTI in patients would reduce UTI complications.
