Open vs Robotic Assisted Partial Nephrectomy

Not Applicable
Terminated
Conditions
Renal Cancer
Interventions
Device: Robotic-assisted partial nephrectomy
Other: Open partial nephrectomy
Registration Number
NCT03849820
Lead Sponsor
Intuitive Surgical
Brief Summary

To demonstrate that Robotic-Assisted partial nephrectomy is superior to Open partial nephrectomy in reducing the number of 30 day post-operative complications (Clavien-Dindo Type I-V) for patients with intermediate to high complexity kidney tumors.

Detailed Description

Partial nephrectomy is the surgical removal of a kidney tumor while unaffected tissue remains intact so that the kidney function is maintained as far as possible. The more radical procedure would be the complete removal of the kidney, which is not examined in this trial.

Surgery will be randomized either to an open technique involving a large incision or the robotic assisted technique with a few small incisions (keyhole surgery). With robotic assisted surgery the movements of the surgeon are translated into the movement of the instruments.

It is not clear which of the two procedures, open or robotic assisted, has less complications. It is expected that these are different due to the different level of invasiveness and the level of direct access to the organ. This study aims to show that robotic assisted surgery results in less complications than open surgery.

Pain assessmentBaseline until Day 90

Assessment of pain level via the Brief Pain Inventory (BPI)

Pain MedicationBaseline until Day 90

Recording pain medication

Kidney function via the estimated glomerular filtration rate (eGRF)Baseline until Day 5 / discharge (whatever is earlier)

Data will be gathered from routine examination, not a mandatory assessment

Conversion from robotic to open, partial to radical

Overall survivalDay of surgery to 5 years

time from surgery to death from any cause

Neuropathic painBaseline and Day 30 and Day 90

Development of neuropathic pain via the DN-4 Patient interview questions

Disease free survivalDay of surgery to 5 years

time from surgery to first documented recurrence of renal cell carcinoma as defined by the investigator

Operative timeDay of surgery

Timing of surgical steps in the OR

Intraoperative blood lossDay of surgery

Volume of blood loss during the surgical procedure

Post operative complicationsDay 90

Any Clavien-Dindo I-V post-operative complication

Procedure related readmissionsDay 90

Readmission that can be linked to the partial nephrectomy

Procedure related reoperationsDay 90

Re-operation that can be linked to the partial nephrectomy

Quality of recovery from the interventionBaseline until Day 5 / discharge (whatever is earlier)

Quality of recovery questionnaire QoR-9

Comprehensive Complication IndexDay of surgery to 30th post operative day

Any complication that occurred within 30 days post surgery

Length of stayDischarge

Time from surgery to discharge

Quality of life questionnaire, generic measureBaseline until Day 90

EQ-5D 5L

Quality of life questionnaire, cancer patient specificBaseline until Day 90

EORTC QLQ-C30

Disease specific survivalDay of surgery to 5 years

time from surgery to death due to kidney cancer

Local recurrence free survivalDay of surgery to 5 years

Time from surgery to the first documented local recurrence e.g. tumor in the operated kidney or in the immediate vicinity (e.g. perirenal fat) at the surgical site. Portside recurrence / incisional, surgical access site recurrence to the affected kidney would also be considered as a local recurrence.
