RESUMEN
A retrospective study was conducted to find out the causative agents of urinary tract infection (UTI) in children and their antibiotic sensitivity pattern among Nepalese children. This was done at Kanti Children's Hospital in Kathmandu (Nepal) by analyzing the records of urine samples collected for culture and sensitivity tests over a period of six months (April to November, 2007). Of the total 1878 mid-stream urine samples collected from suspected cases of UTI, 538 (28.6%) were positive for pathogenic organisms. There was no significant difference in growth positive rate in two genders (M: 51.7% and F: 48.3%). Of the various pathogenic organisms isolated, Escherichia coli constituted for 93.3% followed by Proteus sp, Klebsiella sp, Citrobacter sp, Staphylococcus aureus and others. E. coli was found to be most sensitive to amikacin, chloramphenicol, nitrofurantoin and ofloxacin and least sensitive to most commonly used drugs like cephalexin, nalidixic acid, cotrimoxazole and norfloxacin.
