title: Local anesthesia for transurethral manipulations: is a transrectal periprostatic nerve block effective?
abstract: Periprostatic nerve block has been reported to be an effective form of anesthesia for prostatic surgery. Recent studies have shown the simplicity and the efficacy of a transrectal approach for periprostatic nerve block. The goal of our study was to evaluate the effect of a transrectal periprostatic nerve block on the discomfort associated with rigid cystoscopy. A total of 73 patients underwent cystoscopy. Group 1 (n = 39) received a transrectal periprostatic lidocaine infiltration prior to the cystoscopy. Group 2 (n = 34) underwent cystoscopy alone. The pain that patients experienced during cystoscopy was assessed on a visual analog scale. The patients in the two groups were very similar in regard to age and size of the prostate. The mean pain score was 3.4 in group 1 and 3.9 in group 2. This difference was not statistically significant. We conclude that nerve block does not seem to reduce the pain associated with transurethral manipulations.
