Comparison of perioperative and functional outcomes of robotic partial nephrectomy for cT1a vs cT1b renal masses.

Although our study shows a longer operative time, longer warm ischemia time, and higher complication rate for patients undergoing RPN for cT1b renal masses, the magnitude of these differences is small. RPN should be considered for cT1b lesions when anatomical and spatial location allow for a feasible procedure.
