This study compared the use of external condom catheters and Foley's catheters in bedridden male patients with head injuries. The study found that patients using external catheters had lower rates of urinary tract infections and fewer cases of penile ulceration and edema compared to those using Foley's catheters. The conclusion was that external catheters are preferable for these patients as they do not increase the risk of UTIs or urethral injuries, though care needs to be taken in application to avoid issues with the penis.
