A novel urethral plug assembly having adhesive thereon, wherein the adhesive seals the plug assembly against an internal wall thereby arresting movement of the plug assembly while it functions in the urethra to block the flow of urine therefrom. The plug assembly may comprise a solid body which is of a sufficient diameter to occlude the urethra. Alternatively, the plug assembly may comprise a body which has the ability to change its shape from a compressed to an elongated condition so as to conform to the urethral wall and occlude the opening to the urethra. In one embodiment of the invention, the adhesive lies on the meatal plate of the plug assembly so as to secure the plug assembly against the meatus urinarius. In a second embodiment of the invention, the adhesive is on the body of the plug assembly so as to seal the plug assembly against the urethra, bladder neck or bladder wall. In a third embodiment of the invention, the adhesive is on a portion of the meatal plate so as to seal the plug assembly at the tissue surrounding the meatus urinarius. The adhesive seals the plug assembly in place until the wearer wishes to void, at which point, the seal may be broken by the exertion a downward, pulling force on the plug assembly.
