[Contemporary management of pelvic fracture urethral injuries]

Posterior urethral injuries in men usually result from polytrauma with pelvic fractures and severe associated injuries. If left untreated, posterior urethral injury can lead to severe complications and even death, so precise diagnosis should be made when urethral injury is suspected. The cardinal symptom of urethral injury is blood leakage from the meatus. Retrograde urethrography is the diagnostic tool of choice. In the case of complete urethral avulsion, the formation of a urethral stricture due to pronounced scarring fibrosis is inevitable. In principle, various therapeutic approaches are available. Often, urinary diversion by means of a transurethral or suprapubic catheter is performed first. However, there is also the possibility of direct endoscopic or open urethral realignment with subsequent temporary catheterization. Immediate surgical reconstruction is useful only in exceptional cases of simultaneous bladder neck or rectal injury. In cases of complete urethral avulsion, secondary transperineal bulboprostatic reanastomosis at the interval after three months of suprapubic continuous drainage with excellent success rate is the gold standard and can be supplemented with ancillary maneuvers if necessary to ensure a tension-free anastomosis.
