Urinary tract infection

What is UTI?

A urinary tract infection (UTI) is caused by bacterial infection of the bladder wall. The bacteria irritates the bladder lining and you may feel the need to go to the toilet more often and more urgently, even if there is only a small amount of urine in the bladder. There may also be blood in the urine.  Urinary tract infection is a broad term which covers a variety of infections of the bladder, prostate, urethra and kidneys.
