Causes of urinary tract infections
Several factors have been proposed to result in UTIs. Genetic factors, maternal history of UTI, previous UTI, holding urine for a long time, sexual intercourse, use of diaphragms and spermicides, young age at first UTI (below 15 years), narrowed urethra, prostate enlargement are some of the risk factors that have been associated with increased incidence in young women. Increasing age itself is a risk factor in older women. In case of older men, the incidence of UTI is high in individuals with disease of the prostate and obstruction to the urinary outlet. Surgical instrumentation for various procedures of the urinary tract in both men and women is a common risk factor. In case of young men, UTI was frequently observed in those, whose sexual partners were infected, who had anal sex, who are not circumcised. The UTI in children is usually a secondary infection from nearby regions. Some of the microorganisms that cause UTIs are Escherichia coli, Staphylococcus saprophyticus, Proteus mirabilis and Klebsiella pneumoniae.1–3
