Clinical Trial Summary

Transrectal ultrasound guided prostate biopsy is performed with a periprostatic nerve block to the neurovascular bundle bilaterally. This does not reduce the pain due to probe insertion and manipulation prior to nerve blockage.

Our study goal is to assess whether topical analgesia would reduce pain during the early stages of the procedure.


Clinical Trial Description

Prospective, randomized controlled study. Patients signed an informed consent form. Exclusion criteria were Lidocaine allergy or pre-planned general anesthesia.

Patients were randomized into 6 groups: (1) nerve block with 5 ml 1% lidocaine for each neurovascular bundle + perianal topical application of 10 ml 5% lidocaine cream; (2) as in (1) plus application of 10 ml 5% lidocaine cream evenly on rectal walls. For each approach exposure times of 5, 10 and 20 minutes were allowed, all together 6 groups plus a control group of patients who received periprostatic nerve block only. A 0-10 Visual analogue scale (VAS) was filled by the patients at 5 time points: immediately after probe insertion, during probe manipulation and prostate assessment, immediately following neurovascular bundle nerve blockage, after prostate biopsies and a global pain estimation of the procedure. ;
