Purpose: To compare pain induced by a transrectal ultrasound (TRUS)-guided prostate biopsy in men between using local lidocaine gel or plain lubricant.
Materials and Methods: Between January and October of 2014, a total of 63 consecutive patients undergoing TRUS-guided prostate biopsy for elevated prostate-specific antigen (PSA) levels and/or a suspicious digital rectal examination were randomized to two groups: lidocaine group and control group. In the lidocaine group (n=31), patients received 20 ml of 2% lidocaine gel and betadine solution soaked gauze was administered via a transrectal route 10 minutes before the procedure. In the control group (n=32), 20 ml plain lubricant and betadine solution soaked gauze was administrated under the same condition. After the biopsy procedure, patients were asked to rate their pain perception on a 10-point visual analog scale (VAS) score.
Results: There was no statistically significant difference with the mean patient age, PSA, prostate volume, biopsy duration time between lidocaine group and control group. The mean pain score and number of patients with VAS ≥5 in the lidocaine group (4.14±2.0, 10) were significantly lower than those in the control group (5.78±2.3, 19). In younger men (≤65 years), pain was reported significantly less in the lidocaine group than in the control group. Complication rates were not different between the two groups.
Conclusions: Intrarectal lidocaine gel is a simple, safe, and efficacious for reducing pain and discomfort during the TRUS-guided prostate biopsy procedure. It appears to have an enhanced effect, especially in younger than in older men.
