Many women pee their pants, which is an unspeakable problem for them, especially when coughing, sneezing, laughing, exercising, and involuntarily leaking urine during labor. The amount of urine leakage can be more or less, sometimes a few milliliters, sometimes hundreds of milliliters, and sometimes there is an odor of urine. It is very embarrassing in front of family members and colleagues and neighbors. For a long time, it can also cause urinary eczema and itching in the perineum. Because they are ashamed to talk about it to bring them unspeakable pain and trouble, seriously affecting the quality of life and health. This situation is called “stress urinary incontinence” in our profession, which is caused by the increase of intra-abdominal pressure for various reasons, resulting in the involuntary leakage of urine from the external urethral opening. The incidence of stress urinary incontinence, according to the survey statistics in the survey of the female population accounted for 23%-45%, there are various degrees of incontinence, of which about 50% is stress urinary incontinence, or very high. In the medical profession is receiving great attention. There are several main reasons: 1, age: with age, the prevalence of female incontinence gradually increases, with a high incidence of 45-55 years. The correlation between age and urinary incontinence may be related to the decrease in hormone levels with age, degenerative changes in the urethral sphincter and relaxation of the pelvic floor muscles. 2, childbirth: the number of births, the age of first birth, the mode of delivery, the size of the fetus and the incidence of urinary incontinence during pregnancy are significantly correlated with the occurrence of postpartum incontinence. The higher the number of births, the greater the likelihood of incontinence; women between 20 and 34 years of age at first birth had a higher correlation between incontinence and childbirth than other age groups; women who delivered vaginally were more likely to have incontinence than those who delivered by cesarean section, and women who delivered by cesarean section were at greater risk of incontinence than women who did not have children; the use of midwifery techniques that speed up labor, such as forceps, suction devices, and contractions, also had The use of midwifery techniques such as forceps, suction devices, and contractions to speed up labor and delivery also increase the likelihood of incontinence; mothers with large fetuses are also at greater risk of incontinence. 3, pelvic organ prolapse; pelvic organ prolapse patients pelvic support tissue smooth muscle fiber thinning, disorderly arrangement, connective tissue fibrosis and muscle fiber atrophy may be related. 4, obesity: the chances of obesity stress incontinence significantly higher, weight loss can reduce the incidence of urinary incontinence. 5, race and genetic factors: genetic factors and urinary incontinence have a clear correlation. The prevalence of stress incontinence patients is significantly correlated with the prevalence of their immediate family members. The prevalence of urinary incontinence is higher in white women than in blacks. Stress incontinence occurs as a result of the above-mentioned causes: subluxation of the bladder neck and proximal urethra; reduced closure of the urethral mucosa; reduced function of the urethral sphincter and dysfunction of the nervous system that governs the tissue structures that control urination. Stress incontinence is divided into three degrees according to clinical symptoms: mild: occasional incontinence during general activity and at night without incontinence when abdominal pressure increases, without the need to wear a urinary pad. Moderate: frequent urinary incontinence with increased abdominal pressure and standing activities, need to wear a pad to live. Severe: Incontinence occurs with rising activities or changes in position in the prone position, which seriously affects the patient’s life and social activities. For the female population suffering from stress incontinence, different treatments can be used depending on the degree of symptoms. Mild stress incontinence can be treated conservatively, and moderate to severe can be treated surgically. Conservative treatment methods: 1, pelvic floor muscle training: is a continuous contraction of the pelvic floor muscles (lifting movement) for 2-6 seconds, relaxation for 2-6 seconds, so repeated 10-15 times, 3-8 times a day training, for more than 8 weeks. 2, medication: Midodrine, methoxymin, activates urethral smooth muscle alpha 1 receptors as well as somatic motor neurons to increase urethral resistance. The side effects are hypertension, palpitations, headache and severe episodes of stroke. Surgical treatment: The efficacy is obvious, with short-term efficacy above 90% and long-term follow-up cure rate above 80%, little surgical damage and few complications. We commonly use surgical methods tension-free midurethral sling (TVT and TVT-O), as well as other IVS, TOT, etc.
