Female stress urinary incontinence is a common and frequent disease of middle-aged and elderly women, the symptoms of serious patients will affect the patient’s life and work, many patients are reluctant to go out because of this condition, often incontinence occurs when the abdominal pressure increases, most often occurs in coughing, sneezing, laughing, etc., and some patients incontinence also occurs in the case of a mild increase in abdominal pressure. In the past, there have been various methods of treatment with less than ideal results, we used Johnson & Johnson’s TVT-O Suspension Belt for 10 patients to do transvaginal suspension, the operation was all successful. The effect is obvious and the efficacy is exact. This method, small damage, less patient pain, the operation time in 10-20 minutes to complete, immediately after the operation can improve the patient’s urinary status, postoperative hospitalization time is only 3 days, the disadvantage is that the price of the suspension belt is higher. Stress urinary incontinence patients should do urodynamic examination before surgery, to understand the bladder’s urinary storage and urinary function and urethral sphincter function, but also to understand the incontinence patients leakage point, for the surgical treatment to provide a basis. In patients with mild incontinence, the leakage point is more than 120ml; in moderate cases, it is 90-120ml; in severe cases, it is less than 90ml. In addition there is no condition to do urodynamics hospital, detailed inquiry of medical history, but also can do vaginal lifting test and swab test, etc..
