Objective To investigate the causes of misdiagnosis of acute renal failure (ARF) and the significance of renal biopsy in diagnosis and treatment of ARF. Methods The coincidence rate and misdiagnosis reason of clinical diagnosis and pathological diagnosis were analyzed. The correction rate of diagnosis and treatment after renal biopsy and the effect of early treatment on prognosis were summarized. Results A total of 52 patients (66.7%) were diagnosed clinically and pathologically in 78 cases of ARF. 26 cases (33.3%) were diagnosed incorrectly or the cause was unknown before renal biopsy. Twenty-six cases (33.3% The treatment plan was changed. Conclusion In patients with acute renal failure who have difficulty in diagnosis of clinical etiology, timely renal biopsy should be performed to confirm the diagnosis, guide treatment and prognosis
