Introduction:Obesity represents a barrier to kidney transplantation, but the increasing prevalence amongst renal failure patients has forced some centers to carefully consider such candidates. Morbidly obese patients may be at increased risk of DGF, higher postoperative complications and inferior graft outcomes. Nevertheless, mortality on the waiting list remains significantly higher than after transplant. We have applied minimally invasive robotic surgery to perform kidney transplant in individuals with BMI[sup3]40kg/m2. We compared our results to the national UNOS database.
Methods: The UNOS registry was reviewed for adult LD kidney transplant recipients with BMI[sup3]40kg/m2 performed from September 2009 to December 2014. We compared transplants performed with robotic technique (RKT) versus patients performed with open surgery at all US centers including our own (OKT). Subgroup analysis in patients with BMI[sup3]45Kg/m2 was conducted. We compared outcomes including patient and graft survival, renal function and technical complications.
Results: RKT group had a significantly higher mean BMI overall. The 1-year patient and graft survival rates were similar between groups. Renal function was also similar at 6, 12 and 36 months (Figure 1). Thrombosis caused 1.3% of the graft losses in OKT and 0% in the RKT group. Interestingly, 52.8% of the overall US experience in patients with BMI[sup3]45 kg/m2 was performed with the robotic technique in our center.
Conclusions: Robotic surgery offers similar patient and graft survival with comparable renal function to open technique. RKT permits transplantation in extreme BMI categories without additional technical complications. Further studies are required to establish the role of RKT for obese candidates but preliminary data is encouraging.
