Abstract
The diverse studies in literature concerning the consistency of urine gathered by bag method reveal opposing data. The study appraises the consistency of sterilised bag assortment in a cluster of children who had their first incident of urinary tract infection 1 to 36 months of age.
The research outcomes resulted from a multi-centre prospective randomised study. 410 patients performed 3 successive urinalysis and urine cultures. Urinalysis and urine culture development were held every month to the first 6 months; and then every additional month. The urine was gathered by antiseptic bag assortment in all children.
First urine culture indicated 376 E.Coli, only one urine culture altered from E.Coli to Proteus Mirabilis in the third urine culture. We accomplished 2385 repetitive urinalysis and urine cultures, only one impurity was constricted; 75 patients (22%) had a affirmative urine culture through the follow-up, 51 (15,4%) of them were girls. 26 (1,0%) febrile urinary tract infection were disqualified.  2243 (89%) urine cultures were negative; 33 (1,3%) contaminations; 55 (2,2%) asymptomatic bacteriuria; 26 (1,1%) lower urinary tract contamination. E.Coli was most recurrent micro-organism; it was found in 53 (49%) of all cases and in 75% of higher urinary tract infection.
A few number of infections was constricted in our enormous study, so we consider that sterile bag assortment is reliable.
