IntroductionPelvic trauma is associated in a high rate of patients with posterior urethral injuries. Blood at the urethral meatus or the inability to void are suspicious of urethral damage, but their absence do not exclude it. The attempt to pass a urethral catheter can worse a previous injury.MethodRetrospective study of 565 pelvic trauma along the last 5 years in the Hospital Valdecilla of Santander. We asses the urethral injury according Colapinto and McCallum classification and their relationship with the pelvic trauma, their outcome and diagnosis methodology.ResultsThere was 60 urethral injuries among 565 pelvic trauma (10.61%); 15 (25%) grade I were associated with trauma of the posterior ring of the pelvis; 17 (28.3%) grade II were associated in 12 cases with fractures of the anterior ring and in 5 cases with severe fractures of the posterior ring; 28 (46.66%) grade III were associated in 26 cases with fractures of the anterior ring and 2 fracture-luxation of the posterior one. Against the suggest of avoiding the attempt of passing a urethral catheter, nearly all patients had suffered and attempt before the urologist were asked for. The deferred combined urethrography was the best method of urethral evaluation.
