[Local anesthesia with block of the sexual nerve in conduction of transperineal biopsy of the prostate].

ABSTRACT

We studied 137 males (mean age 68 +/- 8.6 years) with suspected prostatic cancer who had undergone transperineal biopsy of the prostate (12 tissue samples). The biopsy was made under local anesthesia either as paraprostatic block (n=76, group 1) or paraprostatic block in combination with block of the sexual nerve (n=61, group 2). Pain intensity was evaluated with visual analogue scales. Induction of anesthesia was more painful in group 2, three other stages--in group 1. Mean pain at biopsy was significantly (p < 0.001) lower in group 2. Thus, addition of sexual nerve blockade to standard paraprostatic block increases efficacy of anesthesia in conduction of transperitoneal biopsy of the prostate.
