急性肾功衰竭(ARF)是多种病因引起的危重综合征,近年来手术后 ARF 的发病日益增多,已占各种 ARF 的1/3以上。一组437例急性肾小管坏死(ATN)中,各类手术是发病原因的62%,某些血液透析中心的治疗病例中,手术后 ARF 占总入院数25—65%。手术后 ARF 由于致病因素复杂,肾损害常重,病死率在50%以上,因而成为外科的一个严重课题。对术后 Acute renal failure (ARF) is a critically ill syndrome caused by a variety of causes. In recent years, the incidence of ARF after surgery has been increasing, accounting for more than 1/3 of all ARFs. In a group of 437 patients with acute tubular necrosis (ATN), 62% of all causes of the disease were found. In some hemodialysis centers, ARF accounted for 25-65% of all hospitalizations. ARF after surgery because of the complexity of risk factors, kidney damage often heavy, fatality rate of 50% or more, and thus become a serious surgical issues. After surgery
