  • Title: Modified perianal/pericapsular anesthesia for transrectal biopsy of prostate in patients with anal rectal problems.
    Author: Kravchick S, Yoffe B, Cytron S.
    Journal: Urology; 2007 Jan; 69(1):139-41. PubMed ID: 17270636.
    Abstract:
    OBJECTIVES: To modify our technique of perianal anesthesia and use it in patients with painful conditions of the rectum and/or anus. METHODS: A total of 31 consecutive patients with anal-rectal problems underwent prostate needle biopsy. Of these, 17 were referred to our hospital after vain attempts to insert a transrectal ultrasound probe. Patients received a perianal-pericapsular injection of 1% lidocaine. Pain perception was separately assessed for probe insertion and biopsies using a visual pain analog score. RESULTS: Only in 1 patient were we unable to insert the transrectal ultrasound probe. The mean patient age was 65.28 +/- 5.35 years. We performed a mean of 12.25 biopsies per case. At probe insertion, the mean pain score was 2.2 +/- 0.83. During the biopsy punctures, the mean pain level was 2.53 +/- 1.054. We did not find any increase in the complication rate related to the anesthesia method. CONCLUSIONS: Modified perianal anesthesia can be used for transrectal ultrasound-guided biopsy of the prostate in patients with anal-rectal problems, because it provides significant pain relief.
