Preoperative magnetic resonance imaging of the prostate changed the surgical plan in more than one in four patients undergoing robotic-assisted laparoscopic prostatectomy (RALP), according to the results of a single-center study.
After a review of MRI results for the 104 patients in the study, the initial surgical plan was changed for 28 of them (27%). For 17 of these patients, a nerve-sparing technique was used instead; the rest were changed to a non-nerve-sparing technique from a nerve-sparing one, according to Daniel J.A. Margolis, MD, and colleagues from the University of California Los Angeles.
Among those who underwent nerve-sparing surgery, none had positive margins on the side of the prostate where there was a change in plans, according to the results of the study, which was published online in Radiology.
