Surgical Determinants of Outcomes in Partial Nephrectomy: a Contemporary Review.

purpose of reviewPartial nephrectomy has become the preferred treatment for localized renal masses, particularly in the minimally invasive surgery (MIS) era. However, outcomes depend not only on the surgical approach but also on how each step of the procedure is performed. This review examines the key technical steps and clinical determinants that influence oncologic control, renal functional preservation, and perioperative morbidity in contemporary minimally invasive partial nephrectomy. RECENT

findingsRecent evidence highlights the importance of assessing tumor complexity, tailoring ischemia strategies, and selecting resection techniques that maximize parenchymal preservation. Advances in intraoperative imaging, three-dimensional planning, and fluorescence guidance have improved surgical precision and supported more informed intraoperative decision-making. Comparative studies also suggest that techniques such as tumor enucleation and selective clamping can help preserve renal function without compromising oncologic outcomes in appropriately selected patients. Current evidence suggests that outcomes after PN depend largely on tumor characteristics, patient factors, and the way the operation is performed, rather than on the surgical platform itself. Achieving optimal results requires careful preoperative planning, precise surgical technique, and adequate experience. Ongoing advances in imaging integration and intraoperative guidance technologies may further support surgical decision-making and help improve renal functional preservation in nephron-sparing surgery (NSS).
