Performing an MRI before a robotic-assisted laparoscopic prostatectomy (RALP) can help urologic surgeons make more informed decisions as to whether to spare the neurovascular bundle and thus preserve erectile function and continence, according to findings presented at the recent annual meeting of the American Roentgen Ray Society.

As a result of pre-RALP MRI, surgeons changed their nerve-sparing plans for 29 of 104 patients, according to Timothy McClure, MD, and colleagues at the University of California-Los Angeles.
