【Abstract】 Objective:To study the diagnosis and treatment of renal angiomyolipoma.Methods:A retrospective review of 42 cases with renal angiomyolipoma was performed.Results:The positive diagnosis rate of CT was 83.3 %(35/42) and that of MRI 100 %(15/15).17 cases with tumor less than 4 cm in diameter received watchful waiting.of the 25 cases underwent operations,9 cases received nephrectomy,16 cases received partial nephrectomy or tumor enucleation.Conclusion:CT scanning and MRI is the most valuable diagnosis procedure,patients with tumor less than 4 cm in diameter could be treated conservatively,Any operative management should preserve the functional nephrons as much as possible.更多还原
