Summary

This study aims to find out which surgical position is safer and works better for patients candidate to robot-assisted partial nephrectomy (RAPN) - a minimally invasive procedure to remove a small kidney tumor while preserving healthy kidney tissue.

During this operation, the patient can be placed in two different positions:

* the standard flank position, where the patient lies on their side
* a newer supine position, where the patient lies on their back using a technique called Supine Anterior Retroperitoneal Approach (SARA).

Both approaches are performed using the Da Vinci® Single Port (SP) robotic system, a state-of-the-art surgical robot that allows the operation to be done through a single small incision.

The traditional flank position has been used for many years, but it can be uncomfortable for patients and may increase the risk of certain anesthetic or nerve-related complications, especially in people with higher body weight. The new supine SARA technique could make surgery faster, safer, and less painful, but it has not yet been tested in a randomized study.

This is the first clinical trial designed to directly compare these two approaches in patients with small and localized kidney cancers (tumors ≤7 cm, stage cT1).

The study will include 124 patients treated at ASST Grande Ospedale Metropolitano Niguarda in Milan, Italy - a leading center in robotic urologic surgery.

Conditions

  • Kidney Neoplasm

Interventions

OTHER

STANDARD FLANK APPROACH

Patients are positioned laterally (on their side) with the operative flank elevated at a 12-15° angle. The Da Vinci SP robotic system is docked either transperitoneally or retroperitoneally through a single access port.

PROCEDURE

Supine anterior retroperitoneal approach (SARA).

Patients are positioned supine with a mild Trendelenburg tilt (0°-10°). A retroperitoneal space is created through an anterior incision, providing direct access to the kidney without repositioning
