A physiologically acceptable composition comprises a plurality of physiologically acceptable hydrogel particles which have been swollen by an aqueous medium in which they swell and which contain a low molecular weight water soluble organic compound. The concentration of the organic compound is such that the resulting particles require application of an injection force significantly less than when no organic compound is present. The swollen hydrogel particles are substantially insoluble in body fluids. The composition is useful for treating urinary tract disorders.

Composé physiologiquement acceptable comportant une série de particules d'hydrogel physiologiquement acceptables qui ont gonflé dans un milieu aqueux contenant un composé organique hydrosoluble à bas poids moléculaire. La concentration du composé organique est telle que les particules résultantes demandent une force d'injection essentiellement plus faible que lorsqu'il n'y a aucun composé organique. Les particules d'hydrogel gonflées sont essentiellement insolubles dans les liquides organiques. Le composé est utile pour traiter les troubles des voies urinaires.
