The COVID-19 pandemic has caused the destruction of routine hospital services globally, leading to an increase in the backlog of elective surgery cases. The aim of the study was to retrospectively investigate the pandemic's impact on the urologic oncology surgical activity of a high-volume center located in Milan, Italy. The number and type of procedures performed in 2020 during the COVID-19 pandemic was evaluated using 2019 data as control. Waiting times for each surgical procedure were compared, on a bimonthly basis, between the two different years. Overall, a 26.7% reduction in the number of urologic oncology surgeries between 2019 and 2020 was observed (2019: 720, 2020: 528). Both the main indication for surgery and the type of procedure performed significantly differed between 2019 and 2020 (all p < 0.0001), with a decrease in the number of radical prostatectomies and an increase in the number of radical cystectomies and radical nephrectomies/nephroureterectomies performed in 2020. Waiting time decreased by 20% between 2019 and 2020, with the most significant reduction seen after the first wave of the COVID-19 pandemic (July-October 2020), in particular for partial nephrectomy and radical prostatectomy, possibly due to the underdiagnosis of cases. In conclusion, in accordance with recommendations by international urological societies on prioritization strategies for oncological procedures, a higher proportion of surgeries for high-risk tumors was performed in 2020 at our center at the expense of procedures for lower risk diseases; however, future implications for patients' prognosis still need to be determined.
