OVERVIEW OF URINARY TRACT INFECTION

Mustafa et al found that 9.6% of hospitalized patients in Sabah General Hospital had urinary tract infection, which is similar to prevalence reported by other countries. Our urinary system involves kidneys, ureters, bladder and urethra. However, female has shorter urethra compared to male thus increasing the risk of female having urinary tract infection. The infection usually involves lower urinary tract which is bladder (cystitis) and urethra (urethritis).

However, the bacteria may also travel up to kidneys and causes acute pyelonephritis (rare, about 28 cases per 10,000 women per annum). The most common organism that causes UTI is Escherichia Coli (80-85%). Other possible pathogens include Staphylococcus saprophyticus (5-15%), Klebsiella species, Proteus, Pseudomonas aeruginosa, Candida, Enterococci etc.
