What Causes Problems in the Urinary System?
Problems in the urinary system may include conditions such as kidney failure, urinary tract infections, kidney stones, prostate enlargement, and bladder control problems. These problems in the urinary system may be caused by the following: • aging As we age, changes in the structure of the kidneys can cause them to lose some ability to remove wastes from the blood, and the muscles in the ureters, bladder, and urethra tend to lose some of their strength. Urinary infections may occur because the bladder muscles do not tighten enough to empty the bladder completely. A decrease in strength of muscles of the sphincters and the pelvis, that may be associated with age, can also cause incontinence. • illness or injury Damage to the kidneys caused by illness or an injury can also prevent them from filtering the blood completely or block the passage of urine.
