Female urinary incontinence is a common disease in women, and currently, according to global statistics, the prevalence is close to 50%, with severe incontinence at about 7%, about half of which is stress incontinence. The prevalence rate in China is basically comparable to this. Such a large number of people suffering from the disease, the quality of life and health status of women constitute a serious impact. Stress urinary incontinence (SUI) refers to the involuntary leakage of urine from the external urethra when abdominal pressure increases, such as sneezing, coughing or exercise. Symptoms are involuntary leakage of urine during increased abdominal pressure such as coughing, sneezing, or laughing. The sign is the involuntary leakage of urine from the urethra that can be observed during increased abdominal pressure. Urodynamic examination shows involuntary urine leakage on filling cystometry in the presence of increased abdominal pressure with good stability of the detrusor muscle. Conservative treatment methods 1. pelvic floor muscle training (PFMT): Patients can refer to the following method: continuous contraction of the pelvic floor muscle (lifting movement) for 2 to 6 seconds, relaxation rest for 2 to 6 seconds, and so on for 10 to 15 times. Training 3 to 8 times a day for 8 weeks or more. Our department has pelvic floor biofeedback therapy instrument can better help patients master pelvic floor muscle training, compared with simple pelvic floor muscle training, biofeedback is more intuitive and easy to grasp, the efficacy is better than simple pelvic floor muscle training, and it is possible to maintain a relatively long effective duration. 2, weight loss Obesity is a clear correlate of stress urinary incontinence in women. Weight loss can help prevent stress incontinence. Obese women with stress urinary incontinence, lose 5% to 10% of their body weight, the number of incontinence will be reduced by more than 50%. 3, quit smoking: there is evidence that smoking can increase the risk of stress urinary incontinence, although there is no evidence that smoking cessation can relieve the symptoms of stress urinary incontinence, but for the health of patients, it is recommended to quit smoking. 4, change the diet: appropriate to reduce water consumption, reduce the intake of caffeine, alcohol. 5, vaginal weight training Weights (20 g or 40 g) are placed in the vagina to strengthen the contraction of the pelvic floor muscles in order to avoid dislodging the weights to train the pelvic floor muscles, but such treatment generally has poor compliance, is not effective for severe incontinence, and has side effects such as abdominal pain, vaginitis and vaginal bleeding. 6, electrical stimulation therapy through electric current repeatedly stimulate the pelvic floor muscles to increase the contraction of the pelvic floor muscles; feedback inhibition of sympathetic reflexes, reducing bladder activity. However, there is a large variation in reports of this therapy, and large samples and long-term follow-up randomized controlled studies are needed. 7, magnetic stimulation therapy The principle is basically similar to that of electrical stimulation therapy, the difference is that this therapy uses an external magnetic field for stimulation. It can improve the patient’s symptoms, but the application time is relatively short, and a large sample of randomized controlled studies is still needed.
