Transrectal ultrasound-guided needle biopsy of the prostate is routinely performed to diagnose prostate cancer. We performed a prospective study to assess the pain and identify risk factors of pain during prostate biopsy. Prospectively, 131 patients were enrolled. Transrectal ultrasound-guided needle prostate biopsies were performed without any anesthesia. Pain was assessed by using an immediate postbiopsy anonymous questionnaire including a linear visual analog scale (VAS). Six factors were studied (age, prostate volume, cores number, operator, previous biopsy and first core location). Most of the patients tolerated the biopsy with acceptable discomfort. Among the risk factors studied, only first core location influenced the pain. Apex biopsy first was more painful. We recommend starting biopsy with the base.
经直肠超声引导下前列腺穿刺活检常用于诊断前列腺癌。我们进行了一项前瞻性研究，以评估前列腺活检过程中的疼痛情况并确定疼痛的风险因素。前瞻性地纳入了131例患者。在未使用任何麻醉的情况下进行经直肠超声引导下前列腺穿刺活检。通过使用包括线性视觉模拟量表（VAS）的活检后即时匿名问卷来评估疼痛。研究了六个因素（年龄、前列腺体积、穿刺针数、操作者、既往活检及首个穿刺针部位）。大多数患者能耐受活检，不适程度可接受。在所研究的风险因素中，只有首个穿刺针部位会影响疼痛。首先穿刺尖部会更痛。我们建议从基底部开始活检。
