Technical considerations in the use of external condom catheter systems

Since the advent of rehabilitation engineering new advances have been made that have revolutionized condom catheter drainage systems (CCDS). An innovative CCDS has been designed that ensures unobstructed urine flow. Its condom catheter has several unique design features. It has a double row of convolutions near the catheter tip that prevent kinking and twisting so that the pathway remains open. The condom catheter features a unique inner flap that fits snugly on the glans to prevent backflow of urine on the shaft. This condom catheter is connected to a vented leg bag that eliminates the development of a partial vacuum in the connecting tube. This vacuum can create siphoning, which in turn interferes with urine flow into the leg bag. In addition, a new rechargeable battery-operated clipper has been developed that makes nick-free hair removal from the genitals exceptionally easy. This atraumatic hair removal eliminates the pubic hair that becomes trapped under the condom catheter. The clinical impact of these new advances in CCDS requires further investigation.
