Urinary Tract Infection
Urinary tract infection occurs much more frequently in females than in males. This is because the tube between the bladder and the skin surface - called the urethra - is much shorter in the female (no more than a couple of centimetres) than in the male (roundabout 20 centimetres). This means that in females bacteria can easily make their way up the urethra and into the bladder, causing urinary infection. The symptoms are of urinary frequency, urgency and pain, possibly with nocturnal urination and blood stained urine. In the male urinary tract infection is unusual in the absence of an underlying abnormality such as kidney stone, cystic kidneys or prostate problems(see prostate in the male genitalia section), and should be investigated.
