Extravasation of urine is usually due to injury of the urethra in its bulbous or membranous portion, and the fluid, by reason of the anatomic relations, finds its way into the perineal space, the scrotum, the penis and the connective tissue of the anterior abdominal wall. Rarely, the lesion occurs further back in the urethra, so that the urine is prevented from passing forward, but is forced to escape into the connective tissue of the pelvis. The latter condition is difficult of recognition and may readily be overlooked in the absence of operation. An illustrative case has recently been reported by Dr. David Lowson.1 A man received an injury to the perineum by being thrown from a horse, which fell on him. He complained of much pain in the back in the left side of the pelvis and groin. There was little shock and no symptom of internal injury. After
