Urine leakage that occurs when a woman coughs, sneezes or laughs is called stress incontinence. Although incontinence is not a fatal disease, it brings a lot of inconvenience to women’s lives and often makes patients suffer a lot. According to statistics, about 20% of postmenopausal women suffer from it. Stress incontinence is due to factors such as reproductive injury and menopause, resulting in the relaxation of the muscles of the pelvic floor, the pelvic floor muscles of the pelvic organs to support insufficient. The pelvic organs prolapse. Causes the urethra to become shorter and the angle of the bladder to the urethra to change. Causes the urethra to have less control over urine. Clinically, 80% of female stress incontinence is accompanied by varying degrees of bladder bulge, and 50% of bladder bulge has varying degrees of stress incontinence. In women with normal pelvic floor support structures, when abdominal pressure increases, the pressure is transmitted equally to the bladder and urethra and incontinence does not occur. Postpartum and menopause lead to pelvic floor support disorders, the bladder and urethral junction position downward, when abdominal pressure increases (such as coughing, laughing, sneezing, running), the pressure is transmitted only to the bladder, but not to the urethra which is downwardly displaced, and the pressure difference between the bladder and urethra results in the uncontrollable flow of urine. There are three levels of stress incontinence: Mild: occurs when coughing and sneezing, at least 2 episodes per week. Moderate: occurs during daily activities such as walking fast. Severe: occurs when you are in a standing position.
