Urinary incontinence can develop for many reasons, mainly because of problems with the nerves and tissues that control the urge to urinate: atrophy and relaxation of the muscles at the base of the pelvis, located at the neck of the bladder, and dysfunction of the urethral sphincter. Normally, the urethra can counteract any increase in abdominal pressure without incontinence occurring. When the pelvic floor muscles are relaxed and the bottom of the bladder and proximal urethra are displaced downward, the increase in abdominal pressure can cause a corresponding increase in bladder pressure, but at this time the urethral sphincter is relaxed and urethral resistance decreases, resulting in urinary incontinence, which can be clinically manifested as: laughing, coughing, sneezing, running and jumping, violent force, and leakage during sex. The clinical manifestations of urinary incontinence can be divided into five categories: overflow incontinence, non-resistance incontinence, reflex incontinence, urge incontinence and stress incontinence. 1, overflow incontinence is due to more serious mechanical (such as prostatic hyperplasia) or functional obstruction of the lower urinary tract causing urinary retention, when the pressure in the bladder rises to a certain level and exceeds the resistance of the urethra, urine constantly drips out of the urethra. The bladder of such patients is distended. 2.No resistance incontinence is due to complete loss of urethral resistance, and urine cannot be stored in the bladder, and all urine flows from the urethra when the patient is standing. 3, Reflex incontinence is caused by complete upper motor neuron lesions, urination relies on spinal reflexes, the patient involuntarily urinates intermittently (intermittent incontinence), and there is no sensation in urination. 4. Urge incontinence can be caused by strong local irritation such as partial upper motor neuron lesions or acute cystitis, and patients have very severe symptoms of urinary frequency and urgency. Urinary incontinence occurs due to strong uninhibited contraction of the detrusor muscle. 5.Stress incontinence is when the abdominal pressure increases (such as when coughing, sneezing, going down stairs or running) that there is urine flow from the urethra. Stress incontinence is mainly related to bladder and urethral sphincter relaxation and incomplete closure
