Inclusion Criteria: * Patient must be able to provide study-specific informed consent prior to study entry. Exclusion Criteria: * Patient who cannot abide to the departmental hydration protocol * Prostatectomy cases * Acquired Immune Deficiency Syndrome (AIDS) based upon current CDC definition; note, however, that HIV testing is not required for entry into this protocol. The need to exclude patients with AIDS from this protocol is necessary because the treatment involved in this protocol requires contact of ultrasound probe to the perineum area. * Patient enrolled in other clinical trials
