Abstract
The purpose of this study is to validate the feasibility of the robotic technology for various types of renal surgery and to outline the 2-year clinical and pathological outcomes post surgery. In a retrospective chart review with IRB approval of 55 robotic renal surgeries, clinical data and pathological outcomes were recorded, including estimated glomerular filtration rate (eGFR), serum creatinine, radiological surveillance of tumor recurrences and overall quality of life on pre- and postoperative visits at 6, 12, 18 and 24 months. There were 26 robotic partial nephrectomy (RPN), 23 radical nephrectomy (RRN), 3 simple nephrectomy (RSN), and 3 radical nephroureterectomy (RNU) procedures. Twelve patients in the RPN group, 17 in the RRN group and all in the RSN and RNU groups had eGFR <60 ml/min/1.73 m2 and one or more risk factors for chronic kidney disease (CKD) preoperatively. Mean serum creatinine was 1.2, 1.3, 1.2, and 1.8, and eGFR was 66.4, 61.2, 55.8, and 41.0, respectively. There were two distant metastasis and four local recurrences in the RRN group, and two local recurrences in the RNU group. Serum creatinine and changes in eGFR were statistically similar in all groups postoperatively. Cancer-specific survival was 100% for RPN, 83% for RRN, and 100% for RNU while overall survival was 100% for RPN, 76% for RRN, 100% for RSN, and 100% for RNU at 2 years. Robotic renal surgery is a feasible, minimally invasive alternative with promising outcomes in our short-term follow-up. Long-term and comparative studies with open or conventional laparoscopic approaches are needed.
