A patient is brought to the hospital with history of A 8 hours back. A few drops of blood were noted at the external urethral meatus. He has not passed urine and his bladder is palpable per abdomen. What is the probable diagnosis?
The patient in the question following A has blood in the urethral meatus and a palpable abdominal mass both of which indicate the presence of injury to membranous urethra. Injury to membranous urethra occur following fracture of pelvis or avulsion of symphysis pubis. Rupture usually occur at the junction of membranous and prostatic urethra.
