A 50-year-male patient presented to the ER with scrotal swelling which extended to the anterior abdominal wall and upper thigh. The patient gave a history of falling on the cross beam of a bicycle last evening. With history, clinical examination & relevant investigations doctor on duty reached to diagnosis of urethral tear. What is the epithelium seen at the most probable location of tear in urethra in this patient?
The site of injury is membranous urethra. Prostatic urethra - shows transitional epithelium Membranous urethra - shows pseudostratified columnar epithelium Bulbar urethra - shows pseudostratified columnar epithelium Penile urethra - shows pseudostratified columnar epithelium and stratified squamous at opening. Wall of bulbar urethra is thin & suppoed by spongy tissue which makes it very prone to injury & only the injury of bulbar urethra can result in extravasation of urine in superficial perineal pouch. Membranous urethra injury results in urine extravasation in deep perineal pouch Image A shows transitional epithelium. Image B shows pseudostratified columnar epithelium. Image C shows stratified squamous epithelium.
