PURPOSE

1. To discuss the indications for the use of local anesthesia prior to TRUS. 2. To demonstrate the procedure of TRUS guided local anesthesia before prostate biopsy. 3. To estimate the efficacy of TRUS guided local anesthesia before prostate biopsy.

METHOD AND MATERIALS

Administration of local anesthesia prior to TRUS-guided biopsy efficiently eliminates patient discomfort allowing for greater number of biopsies. 2700 TRUS-guided prostate biopsies have been performed following local periprostatic anesthesia from 2000-2005. The procedure begins by injecting 8-15 cc of Xylocaine and 2% adrenaline through the biopsy needle. The technique, its effects on the US image, complications and side effects were compared to 8500 US-guided biopsies performed between the years 1994-2004, without local anesthesia. There was no significant difference between the number and severity of complications in the group with local anesthesia compared to the group without anesthesia.

RESULTS

There was a significant difference between the number and severity of complications in the group with local anesthesia compared to the group without anesthesia: Urinary retention (-30%), severe hematuria (-40%) and urinary infection and septicemia (-32%). There were no significant side effects caused by the infusion of the anesthesia drug. Air bubbles are sometimes infused with the drug causing a "fuzzy" image, which results in a degree of difficulty in guiding the needle. A thorough TRUS examination of the prostate prior to the anesthesia helps the radiologist guide the needle to the appropriate area, even through a "fuzzy" image.

CONCLUSION

US-guided local anesthesia, before TRUS biopsy, assures patient cooperation and is essential for a large (more than 10) number of biopsies. We also noticed a significant reduction of the number and severity of complications.
