The efficacy of periprostatic local anaesthetic infiltration in transrectal ultrasound biopsy of prostate: a prospective randomised control study

It is still uncertain as to which form of anaesthesia is the optimum.

We also assessed the need for local anaesthetic gel for probe lubrication and if the number of cores during biopsy makes a difference in the pain score.
