Abstract:
Eighty six patients with renal masses≤4.0 cm underwent ultrasound or CT-guided core needle biopsies.The clinical data including the initial biopsy technique,pathologic findings,and the clinical outcome were retrospectively reviewed. Biopsies were failed for diagnosis in 6 cases ( 7％ ) because of necrosis or hemorrhage of the tissue specimens.Of 80 successful biopsies,52 cases (65％) were diagnosed as malignant tumor and 28 cases (35％) as benign. Five patients had biopsy complications (6％),including postoperative hypotension,hemouria and perirenal hematoma. Forty-seven patients underwent surgical extirpation ; the consistency rate of histopathological diagnosis between biopsy and surgical specimens was 100％ in these patients.The results indicate that ultrasound or CT-guided core needle biopsy is an effective and safe procedure for diagnosis of renal small masses.
