|- Brief summary||Kidney transplantation is the only treatment offering long-term benefit to patients with chronic kidney failure. In the last decade a huge increase in the use of living donors has been realized for kidney transplantation. However, with it’s increasing use, serious complications become more common, including procedure related mortality. In order to guarantee safety for the donor, it is important to optimise the surgical approach.
The criteria for live kidney donation have extended, leading to the eligibility of obese and elderly donors, but also donors with a complex anatomy. During laparoscopic donor nephrectomy (LDN), dissection of the renal hilum may be more difficult in case of a complex anatomy. During the robotic-assisted donor nephrectomy, the surgeon operates from a seated position at a console. To move the instruments or to reposition the 3D camera, the surgeon simply moves the hands, using multifunctional joysticks. Surgeons will be provided with superior 3D visualization, enhanced dexterity because of an enhanced rotation angle of the robotic wrists (540º vs. 180º in case of laparoscopic instruments being moved by human hands), greater precision and ergonomic comfort. The Da Vinci Surgical System makes it possible for more surgeons to perform minimally invasive procedures involving complex dissection, optimising safety for all living donors.
LDN can cause pain in wrests, elbows, shoulder and neck. When a surgeon experiences discomfort during surgery, it may impede concentration and dissection. Especially in cases where dissection is more difficult, as is the case with complex anatomy, discomfort may increase. The benefits of operating in a seated position may lead to increased safety in these cases and increased comfort for surgeons.
The Erasmus Medical Center has the largest live kidney donation programme in Europe; therefore we feel it is also our responsibility to keep exploring any new developments in this field. The robotic-assisted donor nephrectomy is already accepted and performed in many transplantation centers across the United States of America. However, this popularity may be commercially driven and so far no prospective trials on safety regarding this technique have been published. In this era of evidence based medicine it is not only in the interest of the Dutch research field, but of global interest to fill this void in our knowledge.
For live kidney donors, a robotic-assisted procedure may offer all the potential benefits of a minimally invasive procedure, while safety might be increased. This may especially be the case in donors with complex anatomy and a higher BMI. In an era where treatments are chosen on patient characteristics, the robotic assisted donor nephrectomy may be a valuable addition to the surgical arsenal. Furthermore, this project will help to inform potential donors properly on the advantages of different operative techniques. However, to date no prospective studies have been reported to demonstrate the benefit of robotic-assisted approach.
