Post-Traumatic Retroperitoneal Hematoma Caused by Superior Rectal Artery Pseudoaneurysm.

BACKGROUND Pseudoaneurysms are a known pathology commonly recognized after disruption of the vascular wall leads to the development of a hematoma. Although pseudoaneurysms are common, occurrence in the location of the superior rectal artery is exceedingly rare, has been documented in the literature only 7 times, and can be extremely dangerous. Patients can present with vague abdominal complaints, pain, gastrointestinal bleeding, and development of hematomas, and can progress to hemodynamic instability related to hypovolemia.

Reflux anuria after prophylactic ureteral catheter removal: a case description and review of the literature.

In an attempt to reduce iatrogenic ureteral injury, urologists are frequently called on for placement of prophylactic ureteral catheters in difficult pelvic surgeries. Reflux anuria, which may be more appropriately termed catheter-induced obstructive anuria, has been reported as a complication of ureteral catheter placement and is characterized by the absence of urine output after ureteral manipulation because of edema and obstruction. We report a case of obstructive anuria after bilateral ureteral catheter removal and review the literature regarding this rare complication.
