Optimizing local anesthesia during 10-core biopsy of the prostate

Area of Science:

• Urology
• Anesthesiology
• Pain Management

Background:

• Prostate biopsies are associated with variable pain intensity.
• The effectiveness of different anesthetic techniques for prostate biopsies requires further investigation.

Purpose of the Study:

• To compare the efficacy of various local anesthesia techniques against no anesthesia during 10-core prostate biopsies.
• To identify the optimal anesthetic approach for minimizing pain during this procedure.

Main Methods:

• A prospective, randomized study involving 187 patients undergoing ultrasound-guided 10-core prostate biopsy.
• Patients were allocated to four groups: no anesthesia, prostatic plexus block, apical capsular anesthesia, or a combination of both techniques.
• Pain was quantified using the visual analog scale/numeric analog scale (VAS/NAS).

Main Results:

• Local anesthesia significantly reduced pain scores compared to no anesthesia (mean VAS/NAS: 2.33 vs. 1.68-1.07).
• Anesthesia applied to the apex capsule (Group 3) yielded the lowest mean pain score (1.07).
• Pain associated with the anesthetic injection itself was also recorded and analyzed for each technique.

Conclusions:

• Local anesthesia is effective in reducing pain during prostate biopsies.
• Anesthesia injection onto the apex capsule is the most effective and technically feasible method.
• This technique is recommended for routine use to improve patient comfort during prostate biopsies.
