Ultrasound detection of prostatic calculi as a parameter to predict the appearance of hematospermia after a prostate biopsy

ABSTRACT Purpose: We evaluated the correlation between prostate calculi and hematospermia in patients undergoing prostate biopsy, and its impact on sexual activity of patients. Materials and Methods: A single-center prospective randomized study of 212 patients referred for transrectal ultrasound-guided prostate biopsy (TRUSBx) was performed. All patients were divided into two groups: Group A (GA), 106 patients with moderate/marked presence of prostatic calculi visualized by TRUS; Group B (GB), 106 patients with absence/scarce of prostatic calcifications. Patients were handed questionnaires to obtain a validated data on the duration and impact of hematospermia on sexual activity. The anxiety scores were recorded using a visual analogue scale. Results: No significant difference was noted between the two groups when comparing age, preoperative PSA level, prostate volume, and biopsy number, except for digital rectal examination (DRE) findings. Post-biopsy results of patients included in GA revealed that the complication of hematospermia was present in 65.1%, while in GB was present in 39.7% (p

研究目的：本研究评估接受前列腺活检（prostate biopsy）的患者中，前列腺结石（prostate calculi）与血精症（hemospermia）之间的相关性，及其对患者性生活的影响。
材料与方法：本研究为单中心前瞻性随机研究，纳入212名拟行经直肠超声引导下前列腺活检（transrectal ultrasound-guided prostate biopsy, TRUSBx）的患者。将所有患者分为两组：A组（GA）共106例，经直肠超声检查可见中至重度前列腺结石；B组（GB）共106例，无前列腺钙化或仅见极少量钙化。向患者发放经过验证的问卷，以收集有关血精症持续时间及其对性生活影响的相关数据，并采用视觉模拟评分法（visual analogue scale, VAS）记录患者的焦虑评分。
结果：两组患者在年龄、术前前列腺特异性抗原（Prostate Specific Antigen, PSA）水平、前列腺体积及活检针数方面均无显著差异，仅直肠指检（digital rectal examination, DRE）结果存在差异。A组患者活检后血精并发症发生率为65.1%，B组为39.7%（p
