Comparing Robot-Assisted Laparoscopic Partial Nephrectomy in Prone Versus Lateral Position Using the Extraperitoneal Approach

What this Trial Is About

This research aims to compare two surgical positionsprone versus lateralfor robot-assisted laparoscopic partial nephrectomy performed via an extraperitoneal approach in patients with renal tumors. The study investigates whether the prone position offers safety, feasibility, and any advantages over the traditional lateral position, including any effects on patient prognosis. Researchers will analyze demographic and perioperative data along with long-term follow-up outcomes to understand differences between these approaches. Participants will be randomly assigned to one of two groups surgery performed in the prone position or surgery performed in the lateral position. Both groups will undergo robotic-assisted laparoscopic partial nephrectomy via the extraperitoneal approach according to their assigned position. The study will collect detailed tumor characteristics, patient demographics, and perioperative indicators to evaluate the procedures. Participants will be monitored before surgery and followed with imaging like CT or MRI, and biochemical tests at 1 month, 3 months, 6 months, 1 year after surgery, and annually thereafter. Researchers will assess tumor recurrence, metastasis, postoperative complications, and other perioperative outcomes at multiple timepoints up to 3 years. This ongoing follow-up will help determine the safety and impact of the surgical positions on recovery and prognosis.
