Background: Urinary tract infection (UTI) are the 3rd most common bacterial infection in infants and young children in developing countries after those of respiratory and gastrointestinal tract infection. Because of nonspecific signs and vague symptoms in very young children, they may remain unrecognized. Rapid evaluation and treatment of UTI is important to prevent renal parenchymal damage and renal scarring that can cause hypertension and progressive renal damage. Since gastroenteritis is rampant in developing countries demonstration of an association between UTI and diarrhea will be of clinical significance. The objective of this study was to estimate the prevalence of UTI in children presenting with diarrhea and to identify the clinical co-relates which may guide to identify children with UTI.Methods: This was a descriptive observational study done in 120 children meeting the inclusion and exclusion criteria, who were admitted in the paediatric ward in father Muller medical college hospital for a period of 1 and a half years. After obtaining an informed consent, a detailed clinical examination was performed on children meeting the inclusion criteria and the data was entered to the preformatted sheet. Urine samples were obtained from all the patients by clean catch mid-stream urine sample, following which urine culture was done for all the children.Results: In the present study, out of 120 children presenting with Diarrhea 17% had UTI. E. coli (15 cases) was the most common organism isolated in urine culture followed by Enterococcus. Out of 20 UTI cases, 15 were in the age group of 6 months to 1 year followed by 4 cases among 1-3-year age group.18 out of 20 UTI cases were females. Male:female ratio of UTI patients was 1:9.Conclusions: UTI in young children can present with diarrhea and other nonspecific symptoms. Children presenting with diarrhea need to have a urine analysis and urine culture for the confirmation of UTI, so that long term complications like renal parenchymal damage and hypertension can be prevented.
