It should not be surprising that physicians tend to underestimate the side effects of treatment and that studies that compare physician reporting with patient reporting show a large discrepancy of the incidence of problems as noted in the table below (Blasko , 2000) |

no TURP 11% TURP 54% |
| impotence | 32% | 79% | 27% | 31% | 15-50% | 68% |
| chronic diarrhea | - | - | 2% | 11% | 0% | 9% |
| Side Effect | Percent |
