Abstract

Objectives: Robot-assisted partial nephrectomy is widely performed for small renal masses, achieving excellent perioperative and intermediate oncological outcomes. However, long-term oncological, functional, and quality of life outcomes after robot-assisted partial nephrectomy remain unclear. In this study, we aimed to evaluate quality of life at 1 year and oncological and functional outcomes of robot-assisted partial nephrectomy after a minimum follow-up of 5 years. Methods: Personal, perioperative, postoperative, functional, oncological, and quality of life data were evaluated. The EQ-5D-5L tool, which incorporates health profiles and a EuroQol Visual Analog Scale, was used to assess quality of life preoperatively and 365 days postoperatively. Regarding oncological and functional outcomes, overall survival, recurrence-free survival, and changes in estimated glomerular filtration rate were calculated. Results: There were few changes in levels between the two time points for all EQ-5D dimensions. The mean change in EQ-5D-5L was 0.020 (95% confidence interval 0.006–0.033, P = 0.006), and in EuroQol Visual Analog Scale score 4.60 (95% confidence interval 2.17–7.02, P = 0.0003). Overall and recurrence-free survival 5 years after robot-assisted partial nephrectomy were 97.9% and 92.8%, respectively. After an early postoperative decrease, the estimated glomerular filtration rate remained stable over time. Conclusions: Robot-assisted partial nephrectomy in patients with a T1 renal tumor is safe, feasible, and effective from the perspective of quality of life and survival, even after 5 years. When making treatment decisions, perioperative and quality of life outcomes should be considered together with long-term oncological outcomes.
