Brief summary

This sponsor-initiated, randomized controlled clinical trial aims to demonstrate the clinical efficacy of RUS NE Surgical Navigation System in patients undergoing robotic-assisted partial nephrectomy. The trial will compare the experimental group (n=102) using RUS NE with a control group (n=102), aiming to show an 10% reduction in operation time. The study will involve 6 medical centers in South Korea in patient recruitment and evaluate the clinical efficacy and feasibility of the software, which has been shown to be reliable in previous studies. * Investigational Medical Device: RUS NE (Endoscopic Imaging Treatment Planning Software) * Clinical Trial duration: 24 months from IRB approval -Target number of subjects: Total of 204 participants

Detailed description

After selecting subjects and obtaining informed consent, randomization will be conducted. Robot-assisted partial nephrectomy will be performed using RUS NE or without using software. Parameters-associated with operation or clinical outcomes will be evaluated during hospitalization period or through outpatient follow-ups for up to 3 months after discharge.

Interventions

DEVICERUS NE

The RUS NE is an endoscopic imaging treatment planning software program. It creates a patient-specific simulation of the intra-abdominal surgical environments, allowing for the visualization of tumor, vascular structures and intra-abdominal organs during the surgical planning process and the operation. RUS NE utilizes preoperative CT images of the patients to segment tumor, organs, and blood vessels and reconstructs them into a 3D model. Although there is no direct intervention on the patient, the surgeon uses RUS NE as a surgical navigation tool to simulate the surgery before performing the actual procedure.

Design outcomes

Primary

MeasureTime frameDescription
Operative timeThe operative day (operative day ± 5 days)The duration of time between starting a surgical incision to the last sutures of the operation.

Secondary

MeasureTime frameDescription
Tumor and vessel identification timeThe operative day (operative day ± 5 days)The duration of time between starting manipulation of the surgeon console to the finishing dissection of the hilum and perinephric fat
Resection volumeFrom the postoperative 1week to the postoperative 5 weeksCalculated from the 3-dimensional lengths from the resected renal specimen using ellipsoid formula (π/6XYZ)
Postoperative complicationsFrom the postoperative 8 weeks to the postoperative 16 weeksIncidence of postoperative complications occurred within 4 weeks after the operation. The complications include urine leak, acute kidney injury, renal hemorrhage, fluid collection, abscess, and pulmonary or cardiac complications.
