Summary Uropathies are a frequent etiology of chronic renal failure(CRF) in children. Vesicoureteral reflux (VUR) is detected in 18-50% of children studied during the first urinary tract infection (UTI). Many authorities recommend an interval of 3-6 weeks after a UTI before performing a voiding cystourethrogram (VCUG). However such an interval may reduce the likelihood of completing the procedure as has been documented in different papers of many countries and in our own. This study was performed to evaluate the results of the VCUG done before the first week of the diagnosis of the UTI and compare them with those investigated later. In the period of the study 63 patients were admitted with the diagnosis of UTI. VCUG was performed in 56:88,8%. 73,2% were females, 87,4% were less than 2 years of age. Fever was present in 93 %, gastrointestinal symptoms in 48%, nephrourological manifestations in 21,4%. Escherichia coli was obtained in 91% of the cultures. In 33 patients (59%), VCUG was performed before the first week of diagnosis (early group). In 23 (41%) after the first week (late group). VUR was detected in 11 patients (33%) of the early group and 4 (17,3%) of the late group (p 0,2). There was not significant difference. The comparison of the early group with another one in which all the VCUG were performed after 3 weeks of the diagnosis of UTI 27/60 didn’t showed significant differences either (p: 1). Conclusions: early VCUG didn’t present complications and allowed to evaluate the existence of VUR in a high number of patients. Diagnosis of VUR in the early VCUG is not significantly different from those studied later. Diagnosis of VUR is done late. It is necessary to alert primary attention pediatricians in the adequate diagnosis of UTI and the importance of doing VCUG in these cases.
