"Management of blunt renal injury: what is new?".

The diagnosis, workup and management of blunt renal injury have evolved greatly over the past decades. Evaluation and management of blunt renal injury echoes the increasing success of nonoperative management in other blunt abdominal solid organ injury, such as liver and spleen. Decision-making difficulties still remain regarding the optimal imaging, grading and degree of interventional or operative exploration used. Increasingly, initial nonoperative management has gained acceptance and appears to be applicable even high-grade injuries. Emerging techniques in highly sensitive imaging as well as interventional angiography have allowed safe nonoperative management in the appropriate patient. This review will focus on the contemporary workup and management of blunt renal injury while focusing on some of the emerging literatures in regard to refined imaging and grading of injuries as well as techniques to increase the success of nonoperative management.
