Randomized Controlled Trial Comparative Study
[Comparative study between analgesic efficacy and safety of meperidine compared with lidocaine periprostatic infiltration in transrectal ultrasound guided prostate biopsy].
To assess the efficacy of intravenous analgesia with meperidine compared to periprostatic plexus infiltration with lidocaine, and safety of periprostatic local anesthesia. ⋯ Periprostatic plexus blocked with lidocaine does not offer advantages respect to meperidine, despite the fact that this is a safe method that does not increase the number of complications. Placing transrectal transducer causes more pain than biopsy cores.
