IN PATIENTS with acute renal failure, recovery may be delayed1,2 and has occurred as late as 28 to 34 days.3-6 Persistence of oliguria or anuria beyond that time carries a grave prognosis. Nevertheless, the survival of patients after prolonged periods of oliguria7 suggests that the outlook is not invariably hopeless and that late return of some renal function may unexpectedly occur. It is therefore pertinent to report a patient with renocortical necrosis who made a partial recovery after being maintained by peritoneal dialysis during a period of 49 days of anuria and oliguria. Serial biopsies were a poor guide to prognosis in this case.
