Editing Lower Urinary Tract Trauma (section)

=== Pathogenesis ===
* '''<span style="color:#ff0000">Posterior injuries</span>'''
** '''<span style="color:#ff0000">Almost exclusively associated with pelvic fractures</span>'''
*** '''Urethral injury occurs in ≈10% of males''' and up to 6% of females '''with pelvic fractures'''
**** '''<span style="color:#ff0000">In females, urethral injuries occur almost exclusively as a result of pelvic fracture</span>'''
*** '''<span style="color:#ff0000">The bulbomembranous junction is more vulnerable to injury during pelvic fracture</span>''' than the prostatomembranous junction because the posterior urethra is densely adherent to the pubis via the urogenital diaphragm and the puboprostatic ligaments
* '''<span style="color:#ff0000">Anterior injuries</span>'''
** '''May be blunt''' (e.g., straddle injuries, where the urethra is crushed between the pubic bones and a fixed object) '''or penetrating''', and the urethra may be lacerated, crushed, or disrupted.
** '''<span style="color:#ff0000">Most commonly involves bulbar urethra</span>''' since it is most susceptible to compressive injury due to its fixed location beneath the pubis
