What is UTI

Urinary tract infections (UTIs) are considered as the most commonly diagnosed infectious diseases caused by bacteria. The urinary system is composed of the kidneys, bladder, ureters and urethra. The infection can attack any part of the urinary tract.

  2. Upper urinary tract infection: include pyelonephritis (kidney infection).

Urinary tract infection in men (UTIs in men), causes and risk factors

Urinary tract infections in men tends to be less common compare to women and this is due to the anatomical differences, because the length of the urethra is 20 cm in men in contrast with 5 cm in women.

The risk of infection increases with age in men, specially those have impaired bladder emptying due to prostatic disease.

There are factors that increase the risk of infection in old people, including:

  • • Immobility resulting in poor bladder emptying

  • • Bladder ischemia caused by urine retention
  • • Constipation
  • • abnormal narrowing of urethra
