Robot-assisted Partial Nephrectomy with the new HugoRAS System: single center matched-pair analysis

Area of Science:

• Urology
• Surgical Oncology
• Robotic Surgery

Background:

• Robotic-assisted surgery (RAS) is advancing kidney-sparing procedures.
• Comparisons between new robotic platforms and conventional laparoscopy are crucial for clinical adoption.
• The Hugo™ RAS system is a novel platform for urological procedures.

Purpose of the Study:

• To compare oncological, perioperative, and functional outcomes of robot-assisted partial nephrectomy (RAPN) using the Hugo™ RAS system versus laparoscopic partial nephrectomy (LPN).
• To evaluate the safety and effectiveness of the Hugo™ RAS system in partial nephrectomy within a tertiary care setting.

Main Methods:

• Retrospective single-center study of 165 patients undergoing LPN (n=95) or RAPN (n=70).
• Propensity score matching (1:1) was used to create comparable groups.
• Oncological, perioperative, and functional outcomes, including trifecta and pentafecta success rates, were assessed.

Main Results:

• After matching, 70 patients were in each group; no significant differences in operative time, warm ischemia time (WIT), or estimated blood loss.
• RAPN was associated with a shorter length of stay (3 vs. 5 days, p<0.001) and similar complication rates.
• Renal function preservation (≥90% eGFR) and trifecta/pentafecta achievement rates were comparable between LPN and RAPN.

Conclusions:

• The Hugo™ RAS system demonstrates effectiveness and safety for partial nephrectomy, matching LPN outcomes.
• The study supports the use of the Hugo™ RAS platform for kidney-sparing surgery without compromising oncological or functional results.
