Pure Single-Site Robot-Assisted Partial Nephrectomy Using the SP Surgical System: Initial Clinical Experience.

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Partial nephrectomy is the gold standard for small renal masses.
• Robotic surgery offers enhanced precision and visualization for complex procedures.

Purpose of the Study:

• To describe and evaluate the technique of pure single-site transperitoneal robotic partial nephrectomy.
• To assess the feasibility and safety of the da Vinci SP surgical system for this procedure.

Main Methods:

• Three patients with renal masses underwent robot-assisted partial nephrectomy using the da Vinci SP system.
• Procedures replicated standard multi-port robotic partial nephrectomy steps via a single port.

Main Results:

• All three surgeries were successfully completed using a pure single-site approach without conversion or additional ports.
• Average operative time was 180 minutes, warm ischemia time was 25 minutes, and blood loss was 180 mL.
• All patients achieved negative surgical margins; one required angioembolization for postoperative bleeding.

Conclusions:

• Pure single-site transperitoneal robotic partial nephrectomy with the da Vinci SP system is feasible.
• Further research is warranted to validate these initial findings and long-term outcomes.
