Summary

Robotic partial nephrectomy (RPN) is a safe and effective minimally invasive option for complex renal tumors. This technique successfully preserved kidney function and achieved negative surgical margins in patients undergoing nephron-sparing surgery.

Area of Science:

Urology
Minimally Invasive Surgery
Robotic Surgery

Background:

Laparoscopic partial nephrectomy (LPN) presents challenges, especially for complex renal tumors.
Nephron-sparing surgery (NSS) aims to preserve kidney function.
Robotic assistance offers potential advantages for complex minimally invasive procedures.

Purpose of the Study:

To present the technique and outcomes of robotic partial nephrectomy (RPN) for complex renal tumors.
To evaluate the feasibility and safety of RPN for hilar, endophytic, and multiple renal tumors.
To assess the oncological and functional results of RPN in a series of patients.

Main Methods:

Retrospective review of 29 patients undergoing RPN for complex renal tumors (hilar, endophytic, multiple) between May 2006 and March 2008.

Hilar vessels clamped using laparoscopic bulldog with warm ischemia.

Perioperative data and pathological results were analyzed, with follow-up ranging from 3 to 23 months.

Main Results:

RPN was performed successfully without complications.
Mean tumor diameter was 3.0 cm; mean operative time was 197 minutes; mean blood loss was 220 ml; mean warm ischemia time was 25 minutes.
Histopathology revealed various renal cell carcinomas and benign tumors. All cases had negative margins, preserved renal function, and no tumor recurrence at follow-up.

Conclusions:

Robotic partial nephrectomy is a safe and feasible approach for complex renal tumors requiring NSS.
RPN offers a valuable minimally invasive option for technically challenging renal tumor resections.
Robotic assistance enhances the ability to perform NSS for complex renal masses, benefiting patients.
