Figure 12c. Intraperitoneal bladder injury in a 70-year-old man who had undergone subtotal cystectomy with orthotopic neobladder formation from the cecum. Increased output from the surgical drains was seen 1 week after surgery. (a) CT cystogram shows contrast material within the neobladder. Note the intraperitoneal contrast material leak posteriorly (arrows). (b) CT scan demonstrates a second component of intraperitoneal leakage superiorly into the left lower abdomen adjacent to bowel loops. The posterior and anterior components of the urinoma were both drained under CT guidance with 10-F percutaneous drainage catheters. (c) CT scan demonstrates that the transgluteal urinoma drainage catheter has been advanced into the posterior collection shown in a. (d) CT scan shows that the percutaneous urinoma drainage catheter has been advanced into the anterior collection shown in b. Outputs from the collections diminished over a period of 1 week, and the drainage catheters were removed.
