[Clinical Statistics From 2017 to 2019 in the Department of Urology, Hospital of the University of the Occupational and Environmental Health, Japan].

We introduced the da Vinci Xi surgical system (Intuitive Surgical G.K. CA) in January 2018, and here we report clinical statistics on outpatients, inpatients, and surgical procedures for the 3-year period from January 2017 to December 2019. The number of new outpatients since 2017 has remained almost unchanged at 1,406, 1,530, and 1,494 per year. There was an increasing trend in the number of inpatients, from 862 to 1,021 to 1,239. The main diseases of the inpatients over the 3-year period were bladder cancer in 676 (21.7%), renal cancer in 374 (12.0%), prostate cancer in 268 (8.6%), and urolithiasis in 263 (8.4%). The total number of surgeries in the three years was 1,931. The numbers of transurethral surgeries and laparoscopic surgeries, including robotic surgeries, were 1,063 (55.0%) and 396 (20.5%), respectively. The numbers of inpatients and surgery have been increasing year by year. Medical resources are limited and need to be distributed more efficiently.
