Urinary incontinence is the loss of urinary self-control due to bladder sphincter injury or neurological dysfunction, resulting in the involuntary flow of urine. Urinary incontinence can be divided into five categories according to symptoms: overflow incontinence, non-resistant incontinence, reflex incontinence, urge incontinence, and stress incontinence. For older men, overflow incontinence is more common and results from chronic urinary retention due to prostate enlargement and bladder outlet obstruction. The first thing you need to do is to take medication for prostate enlargement as early as possible. If there is a lot of residual urine, you will also need timely catheterization treatment, and cystostomy is a serious possibility. For older women, stress urinary incontinence is more common. 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 treatments such as estrogen or surgery can achieve better results. As urinary incontinence is often potentially harmful and may lead to urinary tract infections or the risk of urinary retention and hydronephrosis, early treatment is necessary.
