Urethral sphincter insufficiency (ISD) is the incontinence of urine specific problem, because it means a reduction intraurethral pressure at the lack of the activity of the sphincter muscle. From the physical point of view there are three components: 1. the rules of statics of fluids (the ratio of the intraabdominal pressure and atmospheric pressure), 2. the rules flowing liquids (on the basis of Bernoulli's equation), 3. biophysical properties of the sphincter. Sphincter insufficiency causes mechanical leak under pressure drop. This type of incontinence is very difficult to treat. Basically we are using two methods. The implantation of retropubic tape with the possibility of a stroke when you stress test maneuvers or periurethral agents. Both of these methods increase the intraurethral pressure. The syndrome known as "frozen urethra", where the urethra does not move, it is preferable to use periurethral agents. We studied the effectiveness of Bulkamid methods for the treatment of ISD.
