由于前列腺癌的诊断目前仍以病理组织学报告为准，因此，近年来在B超引导下前列腺穿刺活检明显增多。由于穿刺组织小常受到挤压，使前列腺癌的诊断产生了许多困难。因此，有必要总结分析这些难点并进行深入研究，以提高前列腺癌病理诊断的准确率。1材料和方法收集解放军总医院 Since the diagnosis of prostate cancer is still based on the histopathology report, the prostate biopsy under the guidance of B ultrasound has increased significantly in recent years.
