Data are displayed as mean (SD) or n (%). The statistical comparison between groups was performed with Mann Whitney U test, Pearson chi-square test or Fisher's exact test as appropriate.

Final histology Gleason score as determined in prostate specimen after surgery.
Number of patients who had previously received oral 5PDEi following operation.
The patients were asked if they had experienced an adequate response to previous oral medication (5-PDEi). Proportions were calculated from the number of patients who had received previous oral medication (5-PDEi) (Group A: 12/18 and Group B: 9/15).
The patients were asked if they had experienced side effects of any kind to previous oral medication (5-PDEi). Proportions were calculated from the number of patients who had received previous oral medication (Group A: 6/18 and Group B: 7/15).
