Abstract
A physiologically acceptable composition comprises a plurality of physiologically acceptable hydrogel particles which have been swollen in a water solution containing a low molecular weight water soluble organic compound, the solution having the ability to swell the particles. The concentration of the organic compound is such that the resulting particles can be inserted, without use of a carrier liquid utilizing a hand driven hypodermic syringe. The swollen hydrogel particles are substantially insoluble in body fluids. The composition is useful for treating urinary tract disorders.
