Abdominal compartment syndrome due to delayed identification of a ureteral perforation following abdomino-perineal resection for rectal carcinoma.

Abdominal compartment syndrome develops whenever the mean intraperitoneal pressure rises above the physiological pressure, leading to renal and mesenteric ischemia and respiratory decompensation due to pressure on the diaphragm. Abdominal compartment syndrome may occur after conditions such as peritonitis, intestinal obstruction, laparoscopic procedures, or abdominal tumors. Leakage from the urinary tract may cause accumulation of urine in the peritoneal cavity which commonly manifests as single or multiple urinomas, or urinary ascites. The case of a patient who had delayed identification of a ureteral perforation following the abdomino-perineal resection of a rectal carcinoma is presented. Massive urinary leakage into the peritoneal cavity led to the abdominal compartment syndrome. Peritoneal drainage and ureteral stenting improved her condition. A high index of suspicion is necessary in order to diagnose this rare condition.
