There are special requirements for draining a pouch, e.g. length, flexibility and ability to drain highly viscous urine. We checked in vitro the flow time of pure and synthetic urine thickened with hydroxyethylcellulose (0.125% and 0.250%, HEC) on selected catheters.

This article describes a versatile method for the modification of 2-hydroxyethyl cellulose (HEC) involving azide-alkyne cycloaddition reaction to impart neutral (ester) and ionic (carboxylic acid and 1(ry) amine) functionalities. The synthetic approach involved, first the introduction of the azide functionality
