Transrectal ultrasound guided prostatic nerve blockade for pain control during transrectal prostate biopsy / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the safety and efficacy of transrectal ultrasound guided prostatic nerve blockade for pain control during transrectal prostate biopsy.Methods Seventy-three patients requiring systematic 13 cores biopsy of the prostate were randomized into two groups.Group A(37 cases) received an injection of 5 ml 1% lidocaine into the prostatic neurovascular bundles on each side at the base of the prostate under ultrasound guidance,and group B(36 cases) received 5 ml saline ( 0.9% sodium chloride) at the same way.Pain during biopsy was assessed using a 10-point linear visual analog pain scale immediately after this procedure.Results The mean pain scores during transrectal prostate biopsy were significantly lower in group A than that in group B( 1.1? 0.6 vs 5.9? 3.1,t= 4.81,P
