Objective: To determine the effectiveness of the combined apical and basal periprostatic block in comparison to the traditional basal periprostatic block in reducing the pain associated with transrectal ultrasound guided biopsy of the prostate. Materials and Methods: This is a comparative clinical study of patients that underwent transrectal ultrasound guided biopsy of the prostate from June 2006 to September 2007 at the University of Santo Tomas Hospital. Group 1 with 40 subjects who received combined apical and basal periprostatic block was compared with Group 2 with 35 historical subjects who received basal block "alone. A visual analog scale (VAS) was used to assess the pain scores. The t-test was performed on all epidemiologic data. The differences in pain scores were analyzed using multiple analysis of variance (MANOVA). P
