Summary
Periprostatic nerve block with lignocaine significantly reduced pain during prostate biopsies compared to rectal gel or placebo. This technique offers improved analgesia for this common urological procedure.
Area of Science:
- Urology
- Anesthesiology
- Pain Management
Background:
- Prostate biopsies are increasingly common, often performed without anesthesia.
- Growing need for effective pain management during prostate biopsies.
- Current anesthesia techniques for prostate biopsy are varied and require comparison.
Purpose of the Study:
- To compare the efficacy of two local anesthetic techniques for pain control during prostate biopsies.
- Evaluate periprostatic nerve block versus rectal lignocaine gel for analgesia.
- Determine the optimal anesthetic approach for patient comfort during prostate biopsy.
Main Methods:
- Prospective study of 86 men undergoing prostate biopsy.
- Randomization into four groups: periprostatic lignocaine injection, rectal lignocaine gel, and two placebos (saline injection, plain gel).
- Pain assessment using a 10-cm visual analogue scale immediately post-procedure.
Main Results:
- Periprostatic lignocaine nerve block resulted in significantly less pain (P < 0.001).
- Rectal lignocaine gel did not significantly reduce pain compared to controls (P = 0.186).
- No significant pain difference between placebo groups (P = 0.35).
Conclusions:
- Periprostatic nerve block with 1% lignocaine is superior for pain relief during prostate biopsy.
- Rectal lignocaine gel offers no significant advantage over placebo for pain management.
- Periprostatic nerve block should be considered for improved patient analgesia during prostate biopsies.
