Condom catheters are widely used in the management of male urinary incontinence, bedridden patients, and geriatric population. They are considered to be safe; however they are associated with serious complications in case of an incorrect use. We report a dramatic case of penile strangulation by condom catheter tardily discovered till occurrence of necrosis and gangrene leading to death in an elderly bedridden and diabetic man. Through this case we emphasize the importance of patient education for the correct use of condom catheters and remind care providers to maintain a high level of sensibility to complication generated from long-term use of condom catheters.
