Minimally invasive sling surgery is generally suitable for patients with stress urinary incontinence. This surgery is usually not permanent, and its specific name is tension-free urethral suspension. It is used to increase the closure pressure of the urethra. Therefore, when the intra-abdominal pressure increases, the increased urethral closure pressure can prevent urine leakage. This surgery is one of the more common surgeries in clinical practice, but over time, various complications related to the surgery tend to increase. Common surgical complications include difficulty urinating, bladder perforation, and corrosion of the vaginal or urethral sling. Over time, the probability of corrosion gradually increases.
