Is Open Partial Nephrectomy Still an Option in the Robotic Era?

Area of Science:

• Urology
• Surgical Oncology
• Nephrology

Background:

• Robotic-assisted partial nephrectomy (RAPN) is now the predominant surgical approach for small renal masses.
• RAPN is increasingly utilized for larger and more complex kidney tumors.
• Comparative studies show RAPN offers oncologic and functional outcomes similar to open partial nephrectomy (OPN).

Purpose of the Study:

• To review the current role of open partial nephrectomy (OPN).
• To outline indications for OPN in the era of robotic surgery.
• To assess outcomes associated with the open technique compared to robotic approaches.

Main Methods:

• Review of comparative series and meta-analyses.
• Analysis of outcomes data for OPN and RAPN.
• Examination of specific clinical scenarios favoring OPN.

Main Results:

• RAPN demonstrates reduced perioperative morbidity compared to OPN.
• OPN remains crucial for tumors in difficult or re-operative surgical fields.
• OPN is indicated for certain hereditary syndromes, solitary kidneys (preferring cold ischemia), and where robotic access is unreliable.
• Declining open surgical training may impact surgeon competency.

Conclusions:

• OPN is an important option when it offers superior surgical exposure, ischemia management, intra-operative safety, or feasibility of nephron-sparing surgery.
• A pragmatic, surgeon-experience-based approach prioritizing oncologic control, parenchymal preservation, and patient safety is essential for individualized care.
• Both OPN and RAPN have distinct roles in contemporary partial nephrectomy.
