To assess the efficacy and morbidity of periprostatic local anesthesia before transrectal ultrasound-guided biopsy of the prostate.
From August 2001 to December 2001, 58 patients underwent transrectal ultrasound-guided prostate biopsy at the 2nd Department of Urology, Ankara Numune Education and Research Hospital. Fifty patients who fulfilled the inclusion criteria were randomized into 2 groups of 25 patients each. Group 1 received periprostatic local anesthesia with 1% lidocaine while group 2 received no local anesthesia. Pain scale responses were analyzed for each aspect of the biopsy procedure with a visual analog scale.
There was no difference between the 2 groups in pain scores during digital rectal examination, intramuscular injection and probe insertion. The mean pain scores during needle insertion in group 1 receiving periprostatic nerve block and in group 2 receiving no local anesthesia were 3.00 +/- 2.22 and 6.16 +/- 2.85, respectively, and were found to be significantly different (p < 0.001), but morbidity after the biopsy was not statistically different between the 2 groups.
Periprostatic local anesthesia before prostate biopsy is a safe and easy method to increase patient comfort during the procedure.
评估经直肠超声引导下前列腺穿刺活检前前列腺周围局部麻醉的疗效及并发症。
2001年8月至2001年12月，安卡拉努穆内教育与研究医院泌尿外科二科对58例患者进行经直肠超声引导下前列腺穿刺活检。符合纳入标准的50例患者被随机分为两组，每组25例。第1组接受1%利多卡因前列腺周围局部麻醉，第2组未接受局部麻醉。采用视觉模拟量表对活检过程各环节的疼痛程度进行分析。
两组在直肠指检、肌肉注射及探头插入过程中的疼痛评分无差异。接受前列腺周围神经阻滞的第1组和未接受局部麻醉的第2组在穿刺针插入时的平均疼痛评分分别为3.00±2.22和6.16±2.85，差异有统计学意义（p<0.001），但两组活检后的并发症发生率无统计学差异。
前列腺穿刺活检前进行前列腺周围局部麻醉是一种安全、简便的方法，可提高患者在穿刺过程中的舒适度。
