Urinary incontinence is the involuntary overflow of urine from the external urethral opening. It mainly occurs in women and is a common disease that affects women’s quality of life. According to the latest statistics, the prevalence of urinary incontinence among women in China is close to 50%, of which about 50% is stress incontinence. Because women are shy about urinary abnormalities and incontinence symptoms themselves are not life-threatening, they have not been taken seriously by patients for a long time. Most patients with mild and moderate urinary incontinence symptoms tolerate the symptoms on their own, and only choose to consult a doctor when the symptoms worsen to the extent that they seriously affect the quality of life and social activities, which leads to a very low rate of consultation and treatment for female stress incontinence patients. As economic income and living standards continue to rise, female patients have a responsibility to improve their quality of life, and it is essential for both doctors and patients to raise this common and frequent female disease to a new level of awareness. Definition Stress urinary incontinence (SUI) is involuntary leakage of urine from the external urethral orifice that occurs when abdominal pressure is increased by coughing, sneezing, laughing or exercising. Symptoms include involuntary leakage of urine when abdominal pressure is increased by coughing, sneezing, laughing, etc. In common parlance, this means “leakage of urine from the external urethra”. The common saying is “coughing leakage of urine, not coughing not leakage”. Pathogenesis 1, age: with age, the prevalence of female stress urinary incontinence gradually increased, the high incidence of age 45-55 years. The correlation between age and urinary incontinence may be related to the pelvic floor relaxation, estrogen reduction and urethral sphincter degenerative changes that occur with age. However, the slowing down of the incidence of stress incontinence in older women may be related to changes in their lifestyles (e.g., a decrease in daily activities, etc.). 2. Childbirth: There is a significant correlation between the number of births, age at birth, mode of delivery, and size of the baby born and the occurrence of postpartum stress urinary incontinence. The more births, the higher the incidence of urinary incontinence; the reproductive age is too old, the possibility of urinary incontinence is greater; vaginal delivery is more likely to occur than cesarean section; cesarean section than the risk of urinary incontinence than those who have not given birth to a greater risk of urinary incontinence; birth weight of more than 4,000 grams of mothers the likelihood of incontinence is significantly higher. 3, pelvic organ prolapse: pelvic organ prolapse (pelvic organ prolapse, POP) and stress urinary incontinence seriously affects the health and quality of life of middle-aged and elderly women, and the two are often accompanied by the existence of closely related. Pelvic organ prolapse patients pelvic floor support tissue smooth muscle fibers become thin, arrangement disorder, connective tissue fibrosis and muscle fiber atrophy may be related to the occurrence of stress urinary incontinence. 4, obesity: obese women have a significantly higher incidence of stress urinary incontinence; weight loss can reduce the incidence of urinary incontinence. 5, genetic: the prevalence of stress urinary incontinence patients and their immediate family members of the prevalence of a clear correlation. 6, other possible factors, such as estrogen deficiency, history of hysterectomy, high-intensity physical exercise.
