Ferequency of E. coli in Urinary Tract Infection Patients (Complicated Versus Uncomplicated Cas)

Abstract

Objective: To observe the frequency of E.coli among patients suffering from UTI, whether the frequency of
E. coli in UTI patients varies across different age groups and genders, observe potential risk factors, such as
underlying comorbid or lifestyle factors, that may contribute to the prevalence of E. coli in UTI cases,
compare the frequency of E. coli with other uropathogens associated with UTIs and to observe the frequency
of E.coli in complicated and uncomplicated UTI cases. Retrospective cross-sectional study.
Material and Methods: This retrospective cross sectional study at Madinah Teaching Hospital from
January 2023 to July 2023, The details of E. coli grown from urine sample patterns were collected from the
laboratory registers and the patient details were collected from the case records. The urine samples received
were processed using standard methods.
Results: The most frequent organism responsible for UTI was E. coli. 34.5% of cases reported E. coli growth
and other organisms were found in 13.1% of the patients, while the rest showed no growth on urine culture. E.
coli was observed in 66.2% of complicated cases and 29.2% of uncomplicated cases. The most common
comorbid observed in complicated UTIs were urinary tract obstruction (13.8%), Diabetes Mellitus (13.5%),
a urine sample taken from the catheterized patient (10.6%), and pyelonephritis (5.3%). Complications that
arose due to UTI AKI (6.9%) had E. coli frequency of 96.7%, pyelonephritis (6.2%) had 71.4% and sepsis
(8.7%) had 94.8%.
Conclusion: E. coli was responsible for causing UTIs in the majority of the patients. It was the most common
culprit associated with complicated and uncomplicated UTI cases.
