Fifty-one percutaneous renal needle biopsies were performed on 46 patients. Initial biopsy was adequate for diagnosis in 89% of patients. When a second biopsy was performed, this accuracy increased to 98%. Thirty-four of 51 (67%) biopsies were for renal masses and 17 (33%) for medical indications. Computed tomographic guidance was utilized in 94% of cases. Biopsies of renal masses were performed with 18-21-gauge needles, while biopsies for medical indications were performed with an 18-gauge cutting needle or 14-gauge Trucut. A rate of serious complications of 6% was noted.
对46例患者进行了51次经皮肾穿刺活检。初次活检对89%的患者诊断足够。进行第二次活检时，这一准确率提高到了98%。51次活检中有34次（67%）是针对肾肿块，17次（33%）是出于医学指征。94%的病例采用了计算机断层扫描引导。肾肿块活检使用18 - 21号针，而医学指征活检使用18号切割针或14号Trucut针。严重并发症发生率为6%。
