Biomechanical performance of silicone and latex external condom catheters.
Standard in vivo biomechanical performance tests and a pilot clinical study of latex external condom catheters (ECCs) and silicone ECCs demonstrated the superior performance of the silicone ECC over that of the latex ECC. The silicone ECC has a self-adhesive that binds more securely to human skin than the self-adhesive of latex ECC. In addition, the moisture vapor transmission through silicone is significantly greater than through latex. The aggressive self-adhesive of the silicone ECC significantly reduced ECC catheter pop-off compared to that of latex ECC. Silicone ECC removal can be facilitated by the application of a warm, wet cloth to the exterior surface of the silicone ECC, which significantly reduces its self-adhesive force. Constant, gentle traction is then applied to the silicone catheter outlet end to achieve atraumatic silicone ECC removal. On the basis of the results of these standardized tests and pilot study, the silicone ECC is recommended for incontinent men without obstructive uropathy.
