Abstract

Introduction: The peri-prostatic nerve block with lidocaine, provides good pain relief in performing ultrasound-guided prostate biopsy, but the postprocedure pain can be significant, the addition of diclofenac suppository, could provide additional relief. Methods: Patients were randomly assigned in 2 groups to group 1 blockade with lidocaine of the prostatic peri plexus + suppository of diclofenac sodium and group 2 blockade with lidocaine of the prostatic peri plexus + placebo suppository, performing double sextant biopsy, pain at several intervals after the procedure was recorded on a visual analog scale (EVA) from 0 to 10. Results: The 2 groups were similar in terms of age, prostate volume, prostate-specific antigen, histopathological diagnosis. Patients who received diclofenac had pain scores significantly lower than those who received placebo (2 vs. 3.35) p 0.02. Conclusion: Rectal administration of diclofenac before performing a prostate biopsy is a simple procedure that relieves significantly pain experienced without increased morbidity
