We report the surgical management of an expanding 2.5-cm left-sided renal artery aneurysm using a robotic-assisted laparoscopic approach. Using the da Vinci surgical robotic system, we resected the aneurysm, and the anterior-inferior branch of the renal artery was reconstructed with an end-to-end anastomosis. The operative time was 360 minutes, hospitalization length of stay was 3 days, and postoperative analgesic requirements were minimal. Follow-up imaging and functional analysis demonstrated resolution of the aneurysm and preservation of renal function. This technique highlights the ability of surgical robotics to expand indications for minimally invasive surgery in complex cases.
