on the basis of these results a new classification of membranous urethral rupture in cases of fractured pelvis is proposed : type 1 -- the prostate or urogenital diaphragm is dislocated but the membranous urethra is merely stretched and not severed , type 2 -- the membranous urethra is ruptured above the urogenital diaphragm at the apex of the prostate and type 3 -- the membranous urethra is ruptured above and below the urogenital diaphragm .
