Cost Aspects of Radical Nephrectomy for the Treatment of Renal Cell Carcinoma in Korea: Open, Laparoscopic, Robot-Assisted Laparoscopic, and Video-Assisted Minilaparotomy Surgeries

Abstract

PurposeThis study aimed to comparatively evaluate the cost-effectiveness of four different types of radical nephrectomy (RN) techniques: open, laparoscopic, robot-assisted laparoscopic, and video-assisted minilaparotomy surgery (VAMS).Materials and MethodsAmong patients who were diagnosed with renal cell carcinoma and underwent RN, 20 patients were selected who received open, laparoscopic, robot-assisted laparoscopic, or VAMS RN between January 2008 and December 2010. Their medical fees were divided into four categories: procedure and operation, anesthesia, laboratory test, and medical supply fees. The medical costs of the patients were also divided into insured and uninsured costs.ResultsThe total direct cost of VAMS, open, laparoscopic, and robot-assisted laparoscopic RN were 2,023,791±240,757, 2,024,246±674,859 (p=0.998), 3,603,557±870,333 (p<0.01), and 8,021,902±330,157 (p<0.01) Korean Won (KRW, the currency of South Koea), respectively. The total insured cost of VAMS, open, laparoscopic, and robot-assisted laparoscopic RN was 1,904,627±231,957, 1,798,127±645,602 (p=0.634), 3,039,769±711,792 (p<0.01), and 899,668±323,508 (p<0.01) KRW, respectively. The total uninsured cost of VAMS, open, laparoscopic, and robot-assisted laparoscopic RN was 119,163±24,581, 226,119±215,009, 563,788±487,798 (p<0.01), and 7,122,234±56,117 (p<0.01) KRW, respectively. Medical supply fees accounted for the largest portion of the costs and amounted to 33.43% of the VAMS cost.ConclusionsVAMS RN is as cost-effective as open surgery. Furthermore, it is comparatively more cost-effective than laparoscopic and robot-assisted laparoscopic RN.
