Five hundred and eighty-eight patients diagnosed as having PSAGN were treated at our University Hospital and called in for a reevaluation study in 1988 to determine the long-term prognosis of the disease. Fifty-nine patients responded to the follow-up call, all of them being in good physical health. The blood pressure, urinalysis, serum creatinine, blood urea and beta 1C globulin levels were within normal limits. These results led us to the conclusion that the long-term prognosis was favorable in our PSAGN patients since chronic renal failure had not been encountered.
