There are more causes of urine leakage, and the causes of urine leakage in men and women are different, as follows: I. Women: The most common cause of urine leakage is stress urinary incontinence, which is the downward movement of the urinary bladder due to relaxation of the pelvic floor muscles, or resulting in a decrease in the pressure of the middle closure of the urethra, so that urine leakage can occur under abdominal exertion, such as running, jumping, coughing loudly, laughing, etc. Leakage occurs. This condition is often seen in women who have given birth, or who have a history of pelvic surgery, or in women whose pelvic floor muscle strength has gradually relaxed with age. Second, men: the most common is filling incontinence due to chronic urinary retention caused by prostate enlargement. This often occurs in men over 60 years of age, often with a history of difficulty in urination, which can lead to a gradual increase in residual urine in the bladder, and when the residual urine exceeds a certain amount there will be leakage. A hospital visit is required to further determine the cause.
