Urinary incontinence in the elderly refers to individuals over the age of 60 who experience involuntary urine leakage from the urethra, beyond their subjective control. Based on different mechanisms of onset, there are four main types: genuine urinary incontinence, stress urinary incontinence, overflow urinary incontinence, and urge urinary incontinence. Persistent urinary incontinence is due to neurogenic bladder dysfunction, excessive contraction of the urinary muscles, severe damage to the urethral sphincter, and the bladder losing its storage function. This type can be seen in conditions like chronic stroke, dementia, Parkinson's disease, and spinal disease. Stress urinary incontinence occurs due to relaxation of the urethral sphincter, pelvic floor muscles, and muscles around the urethra, leading to reduced urethral pressure. This situation is more common in elderly women and in the perineum of men, or due to urethral damage and urethral surgery. The third major category is overflow urinary incontinence, mainly seen in obstructive lower urinary tract diseases such as prostatic hyperplasia. Chronic urinary retention due to various causes results in bladder pressure exceeding the resistance of the normal urethral sphincter, causing urine to leak from the urethra. Lastly, urge urinary incontinence generally refers to overactivity of the bladder muscles, typically associated with bladder inflammation, acute urethritis, or the presence of bladder stones, bladder tumors, or obstructions at the bladder outlet, all of which can cause urge urinary incontinence.
