Abstract
Most cuff erosions occur on the dorsal aspect of the urethra, suggesting missed injury during mobilization of the urethra from tissues behind it as a common etiology. We agree that most early urethral erosions result from inadvertent injury. However, preservation of urethral blood supply by minimizing mobilization is felt to be a positive attribute of this narrower cuff device. Preservation of urethral vascularity is thought to be of prime importance, especially in cases with an initial compromise to the blood flow secondary to radiation, trauma, or previous urethral surgeries. Of course, using meticulous surgical technique during circumferential mobilization of the urethra and being cognizant of the possibility of injury are prudent practices for minimizing early erosion. Editorial CommentUrologyVol. 77Issue 1PreviewIn comparing the tape mechanical occlusive device (TMOD) with the artificial urinary sphincter, the authors mention that the narrow width of the occlusion tape requires less dissection around the bulbar urethra. They believe this might reduce the risk of urethral injury during urethral mobilization, and this, in turn, might encourage more urologists to use this device. Full-Text PDF
