We present a descriptive study, to perform a noninvasive ultrasound-guided scanning technique that allows repeatable visualization of the pudendal nerve, in its anterior approach. We scanned 56 perineal areas of 28 volunteers bilaterally, analyzing the localization of the pudendal nerve and anatomy of structures around it. Our results shows that the easier way to find the nerve is placing the probe transversal to the line between scrotum or mons pubis and the anal margin, medial to ischial tuberosity; identifying the nerve running along the transverse perineal muscle and medial to pudendal artery. The ultrasound-guided anterior approach of pudendal nerve block is an easy and reliable performing technique, avoiding neuroestimulation or other invasive techniques.
