Flaps for bulbar urethral ischemic necrosis in pelvic fracture urethral injury

Bulbar urethral ischemic necrosis (BUIN) is an iatrogenic entity resulting from repeated attempts at performing anastomotic urethroplasty for pelvic fracture injuries. Etiologically speaking, BUIN related to a compromised blood supply of the bulbar urethra, which normally relies on anterograde arteries and retrograde recurrent branches dorsal penile arteries, through glans. At each transection both supplies are compromised, increasing risk BUIN. Even though this term widely used among reconstructive urologists, orphan accepted scientific definition. We aim report our personal perspective BUIN, identify factors associated with its occurrence, describe management options in these patients.
