causes of uti's in men
In younger men a UTI may be associated with a kidney stone. Bacteria usually cause a urinary tract infection by spreading on the skin from the rectum. into the urethra and then to the bladder or kidneys. Bacteria can also spread from another part of the body through the bloodstream into the. urinary system.
Most cases of urinary tract infections occur in women. Of those that occur in men, relatively few affect younger men. In men older than 50, the prostate gland (a gland near the bottom of the bladder, close to the urethra) can enlarge and block the flow of urine from the bladder. This condition is known as benign prostatic hyperplasia or BPH.
