The technique consists in infiltrating the spermatic cord, as high as possible as soon as it leaves the inguinal canal, with a long-acting non-adrenaline local anaesthetic. It allows evaluating the analgesic effect on a scrotal pain.
Spermatic cord block is effective when spontaneous scrotal pain (without pressure) and pain triggered by palpation of the epididymis or testicle disappear during local anaesthesia.
When a spermatic cord block is effective, it validates that the pain comes from the scrotal area., If the cord block, properly performed, is not effective since the pain is persistent, it is necessary to move towards a referred pain higher height the inguinal region. It can then be a pain whose origin is located either on the course of the ilioinguinal or genito-femoral nerves or at the lumbar level around L1.
There is no consensus protocol for infiltration repetition that has been validated consensually in the literature. The spermatic bloc can be realized in one of our clinics. They are repeated in case of success associated with injectable cortisone. The frequency of cord infiltration is according to the duration of the pain improvement period.
