Simple surgery may correct this embarrassing condition, says Paul Perito MD. According to urologist Paul Perito MD, a vaginal sling procedure is effectively the creation of a support hammock, which aids in the prevention of premature opening of the urethra, from laughing, coughing or sneezing. Paul Perito MD explains that it is a relatively simple procedure that involves installing a small piece of material underneath the urethra. There are a variety of materials available for patients, including synthetic mesh, cadaverous material, and the patient’s own natural tissue.
