Injury to the genitourinary tract is rare, with an incidence of less than 1%. Younger men (mean age, approximately 30 years) are predominantly affected. We introduce an unusual case of a 25-year-old male patient with complete urethral injury combined with a severe open pelvic bone fracture. During the emergency surgery, the primary realignment of the posterior urethra could not be performed due to a large defect. With suprapubic cystostomy alone, follow-up voiding cystourethrography showed spontaneous recanalization of the transected urethra after four months. Suprapubic cystostomy is an efficient treatment option when primary realignment is not possible.
