title: [Clinical study of Silver Lubricath Foley catheter].
abstract: We evaluated the Silver Lubricath Foley Catheter (silver catheter) coated with silver and hydrogel developed to prevent urinary infection, in comparison with the silicone-coated catheter (silicone catheter). Twelve patients ranging from 71 to 95 years of age (median age, 82 years) were catheterized and the 16 of 18F catheter was replaced every 2 weeks. They answered a questionnaire which included inquiry about the treatment with urinary catheter. Because of less leakage and discomfort to the urethra, the silver catheter had advantages over the silicone catheter. The risk of bacteriuria after 14 days of catheterization was not significantly different between the two types of catheter. Scanning electron microscopic analysis revealed that bacterial biofilm developed on the inner surface of both catheters after 14 days of catheterization. On the other hand, the amount of bacterial biofilm on the outer surface of a silver catheter was less than that on the outer surface of a silicone catheter.
