The various methods for anaesthetising the prostate gland. In (1) the needle is positioned just outside the apex and the local anaesthetic is injected to create a pool around it. In (2) the injection has been made into Denonvilliers' fascia, just beyond the rectal wall. In (3) the local anaesthetic has been introduced around the neurovascular bundle, between the base of the gland and the seminal vesicle. Any of these sites can be used, as none is of proven superiority, but both sides should be injected for maximal effect. Reproduced with permission from [14].
