Urinary Tract Infection (UTI)

Urinary tract infection (UTI) is the most common bacterial infection. Upto 50% of women have a UTI at sometime. The prevalence of UTI in women is about 3% at the age of 20, increasing by about 1% in each subsequent decade. In males UTI is uncommon, except in the first year of life and in men over 60, in whom urinary tract obstruction due to prostatic hypertrophy may occur. UTI causes morbidity and, in a small minority of cases, renal damage and chronic renal failure.
