How far has robot-assisted partial nephrectomy reached?

Area of Science:

• Urology
• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Nephron-sparing surgery is the standard for small renal masses (SRM).
• Surgical techniques have advanced from open to minimally invasive approaches.
• Robot-assisted partial nephrectomy (RAPN) represents the latest evolution in this field.

Purpose of the Study:

• To evaluate the safety and efficacy of RAPN for SRM.
• To assess RAPN's utility in complex and challenging renal mass cases.
• To project the future role of RAPN in renal mass management.

Main Methods:

• Review of existing literature on RAPN for renal masses.
• Analysis of oncological and functional outcomes in various patient groups and tumor complexities.
• Comparison of RAPN results with open and laparoscopic partial nephrectomy.

Main Results:

• RAPN demonstrates superior or compatible oncological and functional results compared to traditional methods for SRM.
• Successful application of RAPN in complex cases including large tumors (≥T2), high complexity scores (PADUA/RENAL ≥10), hilar tumors, and multiple tumors.
• RAPN is effective and safe in challenging scenarios such as solitary kidneys, horseshoe kidneys, repeat surgeries, and in obese, elderly, and pediatric patients.

Conclusions:

• RAPN is a safe and feasible technique for SRM, offering excellent oncological and functional outcomes.
• The utility of RAPN extends beyond SRM to complex renal masses and challenging surgical situations.
• RAPN is a valuable and adaptable surgical option for a wide range of patients and renal mass characteristics.
