A urinary tract infection (UTI) is often a painful infection of a part of your urinary system (bladder, kidneys, ureter). UTI’s are the second most common type of infection.
They are more frequent in women—where 50% will have at least one UTI in their lifetime. This is due to the urethra being shorter in women, and therefore less distance for bacteria to travel to the bladder and kidneys.
Others at risk include; diabetics, those with a spinal cord injury, or a recent cystoscopy or post urological surgery.
Most urine infections result from bacteria entering the bladder via your urethra (water pipe).
Risk factors include:
· incomplete bladder emptying
· passing urine infrequently
· sexual intercourse
· anatomical problems in the kidneys, bladder or ureters
Most urine infections are caused by the bacterium E coli, but other types may be responsible (Klebsiella, Proteus). The type of organism can sometimes provide a clue to the underlying causes of infection.
Pyelonephritis is the inflammation of the kidney, again typically caused by E coli — presenting with urinary symptoms, fever and flank tenderness/pain.
Symptoms can vary from mild to severe, and may depend on whether the infection is confined to your bladder or has affected the kidneys also.
The simplest way to confirm an urinary tract infection is by urinalysis. This can be done using a urine ‘dipstick’ which tests for abnormalities ie; blood, protein, glucose, nitrites. Definitive results are diagnosed by use of a microscopy/culture/sensitivity test (MC&S). This requires you to provide a mid-stream sample of urine to be collected in a sterile container and is sent to the laboratory for further testing.
