<prompt> Urine gets collected in which place in case of extraperitoneal rupture of the bladder -Perineal spaceBelow urogenital diaphragmAbove urogenital diaphragmNone of the above  <response>: Bladder rupture is of two types : Extraperitoneal - 80 of cases Intraperitoneal - 20 of cases Urethral rupture is also of two types: Bulbar urethral injury - MC Membranous urethral injury Extravasation of urine in Bladder Urethral injuries. Extravasation of urine blood in bulbar urethral injury It is a superficial extravasation. If the Bucks fascia remains intact, extravasation of blood and urine are confined to the penile shaft. However disruption of Bucks fascia allows extravasated contents into a space limited by colles fascia forms a scrotal and perinea butterfly hematoma which can extend up the abdominal wall. Extravasation of urine in Membranous urethral injury Extraperitoneal bladder rupture. Extravasation is same in both It is a deep extravasation Urine extravasates in the layers of the pelvic fascia and the retroperitoneal tissues Urine collects in the perivesical space. The typical finding on cystogram is extravasation of contrast material into the pelvis around the base of the bladder. Intraperitoneal rupture usually occurs with a direct blow to the lower abdomen with a full bladder. blood urine will extravasate into the peritoneal cavity producing signs of peritonitis.
