目的观察前列腺周围神经阻滞(PPNB)缓解经直肠超声引导下前列腺穿刺活检术疼痛的临床效果。方法选择经直肠超声引导下前列腺穿刺活检术患者80例,根据麻醉方式分为PPNB组(42例)和非PPNB组(38例),对比2组患者疼痛程度及并发症发生情况。结果 2组直肠指检、经直肠超声检查疼痛评分及轻度疼痛发生率比较差异均无统计学意义(P>0.05)。2组患者的穿刺过程疼痛评分比较差异有统计学意义(P<0.05)。2组血尿、尿潴留等发生率比较差异无统计学意义(P>0.05)。结论 PPNB用于经直肠超声引导下前列腺穿刺活检术,可有效降低患者的疼痛感,安全性高,并发症发生率低。
Objective To observe the clinical effect of PPNB in relieving the pain caused by prostate biopsy guided by transrectal ultrasound. Methods Eighty patients underwent transrectal ultrasound guided prostate biopsy were divided into PPNB group (n = 42) and non-PPNB group (n = 38) according to anesthesia. The pain and complications of two groups were compared. Results There was no significant difference between the two groups in the digital rectal examination and the transrectal ultrasonography in pain score and mild pain (P> 0.05). There were significant differences in pain scores between the two groups during puncture (P <0.05). No significant difference was found in the incidence of hematuria and urinary retention between the two groups (P> 0.05). Conclusions PPNB is used for transrectal ultrasound guided prostatic biopsy, which can effectively reduce the pain of patients with high safety and low complication rate.
