Renal failure complicating obstructive jaundice.

Postoperative acute renal failure in patients with obstructive jaundice remains a clinically significant complication. Acute renal failure occurs in approximately 9 percent of patients requiring surgery for relief of obstructive jaundice, and contributes to eventual mortality in 76 percent of those who develop it. The overall mortality rate for patients undergoing surgery for obstructive jaundice is 16 percent. Despite advances in perioperative care, these figures have changed very little over the past 25 years. This article describes the clinical association between jaundice and renal failure and reviews the studies that have contributed to the delineation of the possible underlying pathophysiologic mechanisms, as well as possible preventive measures which have been developed as a result of these investigations. With increased awareness of the potential risk of developing postoperative acute renal failure, the institution of prophylactic measures may result in an improvement in the mortality rate seen after surgery for obstructive jaundice.
