PURPOSE: To assess the frequency of complications specifically related to local anesthetic infiltration prior to transrectal ultrasound (TRUS)-guided prostate biopsy.
METHODS: A total of 200 patients receiving 10 cm(3) (5 cm(3) on each side) of 2% lidocaine injected around the periprostatic nerve plexus under TRUS guidance before prostate biopsy were included. Various complications presumed to be associated with local anesthesia were noted during and after the biopsy procedure. Two weeks later, periprostatic tissue integrity and vascularization were re-examined with TRUS Doppler examination to assess for fibrosis or infection.
RESULTS: The most common finding was pain due to puncture with the needle used for local anesthesia (27%). Also recorded were the need for repeated injections during the biopsy procedure (4.5%), symptoms associated with systemic lidocaine toxicity (2%), urinary incontinence (1.5%), and degradation of the image resolution due to anesthetic injection (1%). Increased vascularization within the periprostatic region was uncommon (2%) on the 2-week follow-up examination. No TRUS finding consistent with rectal wall hematoma or other periprostatic change and no erectile dysfunction associated with the procedure occurred. There was a significant difference in overall pain scores between the subgroups of patients (p < 0.001).
CONCLUSION: TRUS-guided periprostatic nerve blockade is an effective method for relieving discomfort from prostate biopsy with very few complications.
