Background: Urinary tract infections (UTIs) are considered to be the chronic public health problem due to morbidity and financial cost as urological diseases causes the highest health care cost. UTI is known as one of the most common diseases today. UTI can occur in both men and women, but studies found that the incidence of UTI is more common in women especially among the sexually active women.

The study was conducted during the period of February 2018- January 2022. The total sample size for this study was 131.Results:Most of the respondents 56(42.7%) were aged from 26-35 years. Majority of them 117(89%) were female whereas only 14(11%) were male. Burning sensation of micturition was found in 115 patients where 46(40%) had burning for 0-3 days, 63(54.8%) for 4-7 days and 6(5.2%) for >7 days. In most cases causative organism was E. Coli in this study. According to sensitivity patterns of E. Coli Amoxiclav was used in 77(59%) cases and followed by Amikacin in 94(72%), Azithromycin in 120(92%), Cefixime in 130(99.2%), Ceftriaxone in 83(63.3%), Cefuroxime in 37(28.2%), Imipenem in 62(47%), Ciprofloxacine 64(49%), and Gentamicin in 38(29%) cases. In assessing the antibiotic resistance pattern of E. coli Ampicillin was used in 55(42%) cases and followed by Amoxycillin in 98(75%), Colchicine in 13(10%), Linezolid in 35(26.2%), Amoxiclav in 54(41.2%), Colistin in 16(12.2%), Imipenem in 69(53%) and Novobiocin in 62(47%) cases.Conclusions:Antibiotics are considered to be the only treatment for UTI.
