&NA;Three cases of rectal bleeding within a series of 120 transrectal prostatic biopsies are reported. The precipitating factor was the presence of hemorrhoids which were unsuspected prior to prostatic biopsy. Rectal bleeding in these patients was arrested by ballon tamponade with a 24 French Foley catheter.In situmonitoring of the rectal Foley catheter was discontinued when no further rectal bleeding was ascertained. There were no complications due to this simple, safe, and effective technique. When hemorrhoids are suspected, preliminary proctoscopy aids and alerts surgeons to choose alternative routes to the prostatic bed.
