Stress incontinence occurs when the pressure in the bladder is raised and uncontrolled urination occurs. The pressure can be raised by a number of maneuvers, such as straining or twisting. This disorder occurs more frequently in older women, particularly those that have undergone vaginal deliveries of their children. However, it can affect all ages and both sexes, to some degree.
Causes of Incontinence, Stress
Stress incontinence in women is caused by a change in the anatomical relationship between the uterus and the urinary bladder. This results in a shortening of the urethra. There is also a loss of the normal muscular support for the bladder, provided by the muscles that form the floor of the pelvis. These abnormalities occur as a consequence of pregnancy and childbirth, especially repeated childbirth. Other factors include obesity and the natural consequence of aging. In men, damage to the sphincter muscles that guard the exit of the bladder is the main cause of stress incontinence. This can occur with tumors or damage to the bladder, with prostate tumors or cancer and with surgery. Also, the nerves to that region can be injured by tumors, trauma or surgery.
Signs and Symptoms of Incontinence, Stress
Symptoms of stress incontinence include the unintentional loss of urine with lifting, sneezing, singing, coughing, laughing, crying or straining to have a bowel movement.
