[A SUMMARY OF THE FIRST DETAILED ANNUAL REPORT ON NATIONAL CLINICAL DATABASE UROLOGY DIVISION]

(Purpose) National Clinical Database (NCD) in the field of urology in Japan was launched for registration in April 2018. This is a Japanese language summary of the first report, which was published in the International Journal of Urology, which focuses on five surgical procedures that have been registered with detailed information. (Materials and methods) Annual trends of the five surgical procedures with detailed registration in the NCD, namely radical nephrectomy, partial nephrectomy, radical cystectomy, radical prostatectomy, and pyeloplasty, were compiled. (Results) A total of 149,417 patients who underwent the aforementioned five surgical procedures were registered in the NCD during the period covered by this report. The number of patients was 55,630 for radical nephrectomy/partial nephrectomy from April 2018 to December 2021, 83,653 for radical prostatectomy from April 2018 to December 2021, and 9,342 for radical prostatectomy from January 2020 to December 2021. In 2021, 7,416 partial nephrectomies, 7,739 radical nephrectomies, 22,692 radical prostatectomies, 4,677 radical cystectomies, and 792 pyeloplasties were performed. (Conclusion) The report revealed that robotic and laparoscopic procedures have replaced open surgery for all five procedures. Analysis of NCD data is useful for understanding temporal trends in major urological surgeries.
