When is it safe for a rectal biopsy in a patient with prior prostate radiation?  

Is the patient permanently at elevated risk for rectourethral fistula with rectal biopsy? Do you have any threshold for the GI to biopsy a rectal lesion (e.g. not just telangiectasias in the anterior rectum, but truly suspicious rectal neoplasm).
