Urethral Injury Case Study
Type 1 Membranous urethra is stretched but not severed.
Type 2 Membranous urethra is ruptured above the urogenital diaphragm, with extraperitoneal pelvic leakage above the urogenital diaphragm.
Type 3 Membranous urethra is ruptured.
The injury extends into the bulbous urethra.
Leakage above and below the urogenital diaphragm.

(Colapinto and McCallum, 1977). Types of urethral injury by RUG are illustrated in Fig. 9:

(b) Type II urethral injury (c) Type III urethral injury

II Stretch injury Elongation of urethra Without extravasation on RUG.
III Partial disruption Extravasation at the site of injury With visualized bladder.
IV Complete disruption Extravasation at the site of injury Without visualized bladder (Less than 2 cm urethral gap).
V Complete disruption Complete transaction with >2 cm urethral gap;
Or extension into the prostate or vagina.

A more recent classification for urethral injury was developed by the European Association
