Abstract
A composition for injecting into tissues surrounding the urethra or ureter. It comprises a plurality of physiologically acceptable solid polymer particles dispersed in a physiologically acceptable biodissipatable liquid carrier. The polymer comprises a hydrophilic component and may also include a non-hydrophilic component. The polymer hydrates and swells to a predetermined volume as the liquid carrier dissipates. The composition is especially suitable in treating patients with urinary incontinence and patients with vesicoureteral reflux via injection into the tissues around the urethra or ureter.
