An analgesia study of periprostatic nerve block for transrectal ultrasound guided biopsy of the prostate / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the anestheisa efficacy of periprostatic nerve block in transrectal ultrasound (TRUS) guided biopsy of the prostate.Methods A total of 223 patients received prostate biopsy in our hospital from July 2010 to December 2013 were retrospectively studied,and were divided randomly into two groups.One hundred and sixteen cases in nerve block group accepted local anesthesia of prostate capsule and periprostatic nerve block after local perineal skin anesthetia,and 107 cases in local anesthesia group only accepted local perineal skin anesthetia and local anesthesia of prostate capsule.Patients in the 2 groups underwent prostate biopsy successfully.The visual analogue scale (VAS) and complications were recorded.Results The age,serum PSA level before biopsy,prostate volume and the number of puncture needles had no significant differences between the 2 groups (P＞0.05).The average VAS score was 2.3± 1.1,and 4.9±2.3 in the 2 groups.The VAS had significant difference between the 2 groups (P＜0.05).The incidences of hematuria,hemospermia and urinary retention were 37.1％ (43/116),3.4％ (4/116) and 1.7％ (2/116) in nerve block group,and 39.3％ (42/107),4.7％ (5/107) and 1.9％ (2/107) in local anesthesia group.The difference was not significant (P＞0.05).Conclusion Periprostatic nerve block for TRUS guided biopsy of the prostate could be safe with good analgesic effect.
