Objective To analyze the clinical and pathological characteristics of 3 cases with exercise-induced acute renal failure(EIARF).Method This retrospective study included clinical and pathological data of 3 patients with EIARF in our department in 2007.Results These patients manifested nausea,vomit,bellyache,lumbago and acute renal dysfunction or failure after anaerobic exercise,accompanied or not with elevation of creatine phosphokinase or serum myoglobin.Renal biopsy of one patient showed acute interstitial nephritis with slightly focal mesangial proliferative glomerulonephritis.Another showed IgA nephropathy(mesangial proliferative glomerulonephritis).Conclusion Great attention should be paid to this rare disease.
