Robotic Single Port Donor Nephrectomy
November 1, 2019 updated by: Rolf Barth, University of Maryland, Baltimore
Use of the Intuitive Surgical da Vinci® Single-Site™ With Instruments and Accessories for Single-Port Laparoscopic Nephrectomies
Feasibility study on robotic-assisted single-site donor nephrectomy utilizing da Vinci instrumentation and Single-Site platforms.
Study Overview
Status
Completed
Intervention / Treatment
Detailed Description
Our center has performed over 200 single-port donor nephrectomies with standard laparoscopy and has reported patient benefits associated with a single port approach.
The single port robotic platform offers the potential to ameliorate the significant technical and ergonomic challenges that currently limit more widespread application of single port donor surgery.
After being informed of the potential risks and off-label use of the da Vinci Single-Site approach in our study, patients will undergo a robotic-assisted single-site donor nephrectomy performed by a two-surgeon team utilizing existing da Vinci instrumentation and Single-Site platforms.
Renal mobilization and vascular dissection will be performed with manual laparoscopy performed for vascular division utilizing stapling devices.

Measure Description |
Time Frame |
---|---|---|
Successful Completion of the Surgical Procedure
Time Frame: during operation
|
The primary objective is to determine the feasibility measure of the current Single-Site platform to perform donor nephrectomy prior to vascular division and extraction.
Specifically, it will be recorded which portions of the operation utilized the robotic device.
The primary outcome variable is the completion of the operation for kidney donation.

The Comparison of Surgeon Ergonomic Questionnaires in Robotic Assisted Versus Standard Laparoscopic Single Port Donor Nephrectomies.
Time Frame: intra-operative experience collected within 24 hours
|
A surgeon ergonomics questionnaire will be given to surgeons after performing both robotic assisted and standard laparoscopic single port donor nephrectomies.
The results from both of these surveys will then be compared.
These are qualitative and were not analyzed for statistical trends.
