Minimally invasive robotic kidney transplantation for obese patients previously denied access to transplantation

Abstract

Obese patients with end-stage renal disease (ESRD) are often excluded from kidney transplantation due to concerns about surgical site infections. To reduce infections, we developed a robotic kidney transplantation method for obese recipients. From June 2009-December 2011, a prospective cohort of 39 obese patients underwent robotic kidney transplantation at a single center. The outcomes of patients with at least six months of follow-up (n=28) were compared to a frequency-matched retrospective cohort of obese patients who underwent open kidney transplantation from 2004-2009 (n=28). The 28 robotic patients were predominately African-American (46.4%) or Hispanic (35.7%), with a mean age of 47.9±10.7 years, similar to the control group. BMI in the robotic group was 42.6±7.8 kg/m2 compared to 38.1±5.4 kg/m2 in the control group (p=0.02). There were no surgical site infections in the robotic group (0/28), while 28.6% (8/28) in the control group developed an infection (p=0.004). Six-month creatinine (1.5±0.4 vs.1.6±0.6 mg/dL; p=0.47), and patient and graft survival (100%) were comparable between the two groups. Outcomes following robotic surgery compared favorably to conventional transplantation. Robotic surgery may therefore enable obese patients with ESRD to access kidney transplantation and may thereby reduce health disparities in groups with a high prevalence of obesity and ESRD.
