各種カテーテルを実際に患者に使用して,その表面への細菌の付着性と,尿道粘膜への刺激性を比較した。親水性素材でcoatingしたカテーテルが従来から使われているテフロンやシリコン製と比べて,最も細菌が付着しがたく,局所刺激も少ないTo prevent the occurrence of nosocomial urinary tract infections among patients with indwelling urinary catheters, we compared commercially available catheters for the degree of irritation to surrounding mucosa and bacterial adherence. The hydrogel-coated catheter was found to be superior to the teflon-coated or silicone-coated catheters, since it had the lowest degree of bacterial adherence and mucosal irritation among these products. These findings suggest that the incidence of catheter-induced urinary tract infection would be lowered by the use of hydrogel-coated catheter, and recommend their use for patients requiring long-term urinary catheterization.
