Hydron, a polymeric gel which permits the passage of small molecules through its interstices, was used to coat latex urethral catheters. These catheters, as well as other catheters of varied composition, were exposed to a liquid environment from which struvite crystals could be precipitated. The deposition of struvite on a hydron coated latex catheter was significantly less than upon the other catheters.
氢化聚合物凝胶（一种能使小分子通过其孔隙的聚合物凝胶）被用于包覆乳胶尿道导管。这些导管以及其他成分各异的导管被置于一种能沉淀鸟粪石晶体的液体环境中。鸟粪石在氢化聚合物凝胶包覆的乳胶导管上的沉积明显少于其他导管。
