The Long Term Effect of MRI Before Radical Prostatectomy.

A randomized clinical trial conducted by Oslo University Hospital between 2010 and 2012 included 438 patients with prostate cancer to the non-MRI group (216) or the MRI group (222) before robot-assisted radical prostatectomy (RALP). The primary endpoint was to compare the nerve-sparing surgery types and the proportion of positive surgical margins (PSM) in each group. The MRI group underwent more non-nerve sparing surgery, whereas the proportion of PSM was similar in both groups (p=0.4) \[1\]. Since the long-term effects of preoperative MRI are unknown, we aimed to assess the variations in the long-term functional and oncological outcomes between the groups.
