Most of the deaths in this category are due to urinary tract infection, often then leading to kidney failure.

South London, east London and Essex are the blocks of colour on the map opposite that first catch your eye as reflecting unusually large areas of the population suffering elevated rates of mortality from these disorders. At least a dozen other smaller areas can also be singled out for speculation. Just as significant are the places where an unusually large number of people are clustered together who have had a lower than normal chance of dying from these disorders over many years. Such places are more often found around the coasts and away from most city centres.

Urinary tract infection (UTI) is a bacterial infection in the urinary tract that can occur from the urethra through the bladder to the renal pelvis inside the kidney.

Recurrent UTI can lead to kidney stones and kidney failure. UTIs often occur in the hospitalised elderly, for instance after a stroke or a fall.
