Fig. 33-1. The urinary bladder empty (A) and full (B). The peritoneum is stripped away from the anterior abdominal wall as the bladder fills. Hence access to a full bladder may be gained extraperitoneally (t, trocar; in B). Rupture may be intraperitoneal (i) or extraperitoneal (e). In A, the prostate is being palpated per rectum.
