title: [Penile block in adults].
abstract: A block of the penile nerves provides a sensory blockade of the penis. In adults, surgery can thus be carried out on the foreskin, glans, corpus cavernosum, corpus spongiosum or penile urethra. The two dorsal nerves of the penis can be blocked by two different routes. In the median technique, only one injection is performed in the subpubic space, near the posterior inferior aspect of the symphysis. In the bilateral technique, each penile nerve is blocked separately at the level of the penile root. Whichever technique is used, additional subcutaneous infiltration of the penile root improves the quality of analgesia. Bupivacaine without adrenaline is used at a concentration of 0.25% or 0.5%. In the median technique, bilateral diffusion of the anaesthetic solution has been demonstrated in ten patients by adding contrast medium to the anaesthetic solution. On the other hand, contralateral diffusion was only found in six of ten patients after an unilateral injection. These results substantiate the value of the bilateral technique in the adult. Both techniques were used in a group of 80 patients, aged 17 to 87 years. In 47 patients no other agent was administered, while the remaining 33 had either additional sedation or a general anaesthetic. Among the latter, three had a partial failure of the block. Postoperative analgesia, which was of excellent quality, covered an average of 10 hours. Neither local nor general incident occurred. Penile block is a reliable technique for regional anaesthesia. Because it is easy to carry out, and comfortable for the patient, this technique may be suggested to adults requiring penile surgery.
