Urinary incontinence is a collective term for the involuntary flow of urine and is often divided into stress incontinence, urge incontinence and filling incontinence. Urinary incontinence is a common problem in the elderly population, and the cause needs to be identified and treated symptomatically. The causes of urinary incontinence are often different in men and women. Overflow incontinence often occurs in older men. It is caused by chronic urinary retention due to prostate enlargement and bladder outlet obstruction. The fact that the prostate gland is becoming increasingly obstructive to the bladder outlet as we age, coupled with the declining function of the bladder forcing muscles with age, gradually leads to overflow incontinence, a state that requires prompt medical attention. This is the first time that you should take medication for prostate enlargement, and if there is a lot of residual urine, you will also need timely catheterization treatment and a serious cystostomy is feasible. Stress urinary incontinence occurs more often in older women. It is often due to the relaxation of the pelvic floor muscles in menstruating women as they age, resulting in insufficient strength of the urethral sphincter, which can involuntarily produce urination during coughing and squatting or abdominal exertion, seriously affecting the quality of life. Current pharmacological treatment such as estrogen or surgery can achieve better results. In summary, the elderly urinary incontinence is still recommended to promptly seek medical examination to clarify the cause, symptomatic treatment, as urinary incontinence is often potentially harmful, may lead to urinary tract infection or urinary retention risk of hydronephrosis, must be treated early.
