Objective:
To compare preprocedure Diclofenac suppository and Xylocaine gel with Xylocaine gel only in patients undergoing transrectal ultrasound (TRUS)-guided biopsy of prostate for pain.
Materials And Methods:
It is a randomized controlled trial conducted on patients undergoing TRUS-guided biopsy for clinical or biochemical suspicion of prostate cancer following a written informed consent and Ethics Review Committee approval. Patients were randomized into 2 groups. Group A included those patients who received Diclofenac suppository 2 hours before in combination with 10 mL of 2% Xylocaine gel 5 minutes before biopsy. Group B received Xylocaine gel only. A visual analog scale was used to measure the pain scores at the time of TRUS probe insertion, just after taking biopsy cores and 2 hours after biopsy.
Results:
A total of 100 patients were recruited in the study with 50 patients each in group A and B. Mean age of group A was 69.1 ± 10 years and 67.3 ± 8.1 years for group B. The mean pain score for group A and B at the time of probe insertion was 0.08 ± 0.27 and 0.34 ± 0.63 (P = .032), immediately after taking biopsy cores was 1.46 ± 1.15 and 4.68 ± 0.77 (P = .000), and 2 hours after biopsy was 0.14 ± 0.45 vs 2.40 ± 0.81 (P = .000), respectively.
Conclusion:
The mean pain score at the time of TRUS probe insertion, immediately after taking biopsy cores, and 2 hours after biopsy is statistically significantly higher in group B.
