An injury to the urethra leaving Buck's fascia intact results in a collection of<unk> <unk>  limited to the penis, deep to Buck's fascia. However, if the injury to the bulb of the penis results in urethral injury accompanying a tear of the Buck's fascia, then extravasated blood and<unk>  would accumulate in the superficial perineal space, passing into the penis (outer to Buck's fascia) as well as the scrotum and lower anterior abdominal wall.<unk>  involving a compromised Buck's fascia can be appreciated clinically by blood collecting in the superficial pouch, resulting in a 'butterfly'-shaped region around the penis.
