Robotic Pyelolithotomy, Extended Pyelolithotomy, Nephrolithotomy, and Anatrophic Nephrolithotomy

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Renal stones disease management presents challenges, particularly for large or complex calculi.
• Anatomical anomalies can complicate traditional surgical approaches for kidney stones.

Purpose of the Study:

• To report on the indications, techniques, and limitations of robotic surgery for renal stones.
• To evaluate the efficacy of different robotic surgical approaches for managing complex kidney stones.

Main Methods:

• Description of three robotic techniques: robotic pyelolithotomy (RP), robotic nephrolithotomy (RN), and robotic anatrophic nephrolithotomy (RAN).
• Patient positioning, port placement, and surgical steps for each technique are detailed.
• Hilar vascular control requirements are specified for different procedures.

Main Results:

• Robotic pyelolithotomy and nephrolithotomy achieved nearly 100% stone-free rates.
• Robotic anatrophic nephrolithotomy, a complex procedure for complete staghorn stones, demonstrated a 70% success rate.
• Renal vascular control was often avoidable for RP and RN, but required for RAN.

Conclusions:

• Robotic surgery is a viable option for managing large renal and ureteral stones.
• It is particularly beneficial when endoscopic approaches are unsuccessful or not feasible.
• Specific robotic techniques are suited for different stone burdens and anatomical complexities.
