Fewer Complications With Robotic Nephrectomy in Complex Kidney Tumors - Medpage Today
Robotic-assisted partial nephrectomy (RAPN) led to a lower rate of complications compared with open partial nephrectomy (OPN) in patients with intermediate- or high-complexity kidney tumors, the randomized OpeRa trial found. Among over 200 patients, 36.6% of those who underwent RAPN had a postoperative complication of any kind within 30 days -- the trial's primary endpoint -- compared with 46.1% of those who underwent OPN, reported Marc-Oliver Grimm, MD, of University Hospital in Jena, Germany, during a presentation at the European Association of Urology (EAU) annual congress. While that difference was "close to the 10% we expected," Grimm said, he acknowledged the trial was not statistically powered to show a significant difference in its primary endpoint, since it was stopped prematurely due to slow enrollment. "The main difference in favor of the robotic arm was due to low-grade complications," he noted. "High-grade complications were, in gener
