[Clinical diagnosis and treatment of 27 cases of metanephric adenoma].

The clinical features, imaging features, treatment methods and pathological features of 27 patients with metanephric adenoma were analyzed. It was found that the clinical features and imaging features of metanephric adenoma were difficult to differentiate from renal malignantology. Pathology can be clearly diagnosed and some can be combined with malignant components. Nephron sparing surgery is the first choice, and the prognosis is good, but still need regular follow-up.
