To analyze the efficacy of intrarectal ice application as an anesthetic method prior to transrectal ultrasound (TRUS) guided prostate biopsy.
A total of 120 consecutive men were included into the study prospectively. Patients were equally randomized as group 1 and 2 with 60 patients each. Ice was applied as an anesthetic method 5 minutes before procedure to the patients in group 1. Patients in group 2 were applied 10 mL of 2% lidocaine gel 10 minutes before procedure. Twelve core biopsy procedure was performed for all patients. The pain level was evaluated using a visual analogue scale (VAS).
Median pain score was 3.5 (1-8) in group 1 and 5 (1-8) in group 2. There is significantly difference between groups regarding the mean sense of pain level during the procedure. (p=0.007) There was also no difference in complications between two groups about presence and duration of macroscopic hematuria and rectal bleeding.
Intrarectal ice application prior to TRUS prostate biopsy has an effect on reducing pain. Development of new techniques about cold effect or ice can make this method more useful and decrease complication rates.
分析经直肠超声（TRUS）引导下前列腺活检前经直肠应用冰作为一种麻醉方法的疗效。
前瞻性纳入120例连续的男性患者。患者被随机分为1组和2组，每组60例。对1组患者在操作前5分钟应用冰作为麻醉方法。对2组患者在操作前10分钟应用10 mL 2%利多卡因凝胶。对所有患者均进行12针活检操作。使用视觉模拟量表（VAS）评估疼痛程度。
1组的中位疼痛评分为3.5（1 - 8），2组为5（1 - 8）。两组在操作过程中的平均疼痛程度感觉上存在显著差异（p = 0.007）。两组在肉眼血尿和直肠出血的发生情况及持续时间方面的并发症也无差异。
TRUS引导下前列腺活检前经直肠应用冰对减轻疼痛有作用。关于冷效应或冰的新技术发展可使该方法更有用并降低并发症发生率。
