CTガイドによる傍大動脈領域の生検 - 3症例の報告 -

Abstract

Computed tomographic (CT)-guided biopsies of the lesions in paraaortic region were performed for three urologic disease conditions: retroperitoneal fibrosis, lymph node metastases of transitional cell carcinoma of renal pelvis and lymph node metastasis of renal cell carcinoma. The biopsies were performed without complications using the Bard Biopty biopsy gun with a Bard Biopty-Cut needle. Every biopsy specimen we obtained by the Biopty rendered an excellent biopsy core from which a definite histopathological diagnosis was made. CT-guided biopsy is considered to be safe and useful for diagnosis of the disease of the paraaortic region, even when ultrasonography guided biopsy is difficult. The use of the Biopty for CT-guided biopsy provides a high quality specimen for histopathological diagnosis.
