Preoperative MR can help surgeons limit nerve damage while performing a robotic assisted laparascopic prostatectomy (RALP)—saving some men from becoming impotent, according to a study performed at the University of California, Los Angeles, CA.
Preoperative MR was used to evaluate 38 neurovascular bundles in 19 men who were set to undergo RALP. "Prostate MR changed the neurovascular resection plan in 20/38 neurovascular bundles," said Timothy McClure, MD, lead author of the study. "12/20 underwent a more aggressive nerve sparing technique and 8/20 underwent a more conservative nerve sparing technique. Both aggressive and conservative techniques are less likely to cause impotency than RALP," said Dr. McClure.
"RALP is becoming more common. When using the robot in surgery, the surgeon has improved visualization and manual dexterity but at a loss of sense of touch," he said.
"MR before RALP appears to help surgeons make a more informed decision with regards to the aggressiveness of nerve sparing surgical technique without compromising the oncologic outcome," said Dr. McClure.
This study will be presented at the 2009 ARRS Annual Meeting in Boston, MA, on Monday, April 27. For a copy of the full study, please contact Heather Curry via email at hcurry@arrs.org.
About ARRS
The American Roentgen Ray Society (ARRS) was founded in 1900 and is the oldest radiology society in the United States. Its monthly journal, the American Journal of Roentgenology, began publication in 1906. Radiologists from all over the world attend the ARRS annual meeting to participate in instructional courses, scientific paper presentations and scientific and commercial exhibits related to the field of radiology. The Society is named after the first Nobel Laureate in Physics, Wilhelm Röentgen, who discovered the x-ray in 1895.
