ConvaTec’s GentleCath Hydrophilic Male Length Catheter works great for a low-friction self-catheterization. This is due to the hydrophilic polymer coating bonded to each catheter's surface. Once activated by water from the included water sachet, the coating becomes slippery with its own lubrication. It will stay comfortable and smooth throughout cathing from insertion to withdrawal. Unlike other options, the lubrication on the GentleCath Hydrophilic Male Catheter will not slough off. In addition, hydrophilic catheters are proven to reduce the risk of urinary tract infections (UTIs)
