title: [Diagnosis and treatment of renal oncocytoma of 6 cases and literature review].
abstract: To improve the diagnosis and treatment of renal oncocytoma and avoid unnecessary radical nephrectomy. The clinical data of 6 cases of renal oncocytoma diagnosed at the Second Xiangya Hospital Central South University from March 2005 to November 2010, including symptoms, laboratory tests, imaging, style of operation, pathological examination, and follow-up were retrospectively analyzed.There were no special symptoms and obvious abnormal laboratory tests in the patients. Two patients had relatively special imaging. Partial nephrectomy was performed in 2 cases of renal oncocytoma with typical imaging, while radical nephrectomy was performed on other patients because of misdiagnosis. No relapse and metastasis were found in the following 1 to 5 years.Renal oncocytoma is an uncommon benign tumor. Partial nephrectomy or tumor excision can be performed on patients diagnosed with renal oncocytoma according to typical imaging and intraoperative frozen section biopsy. The final diagnosis depends on pathological examination and regular follow-up is imperative for patients with renal oncocytoma.
