Abstract In January 2019, the use of the UroVysion® urine test for surveillance of non-muscle invasive bladder cancer with carcinoma in situ (CIS) was approved in Japan. Clinical evidence of its use remains limited. Herein, we report the real-world clinical practice of the UroVysion test. Of 29 patients underwent at least one UroVysion test at our hospital from 2019 to 2022, only two (6.9%) tested positive without any visible tumor on the cystoscopy after the initial transurethral resection: a 77-year-old man with T1 high-grade tumor and concomitant CIS and a 76-year-old woman with CIS. The remaining 27 patients (93.1%) tested negative post-transurethral resection. This study was the first to report the Japanese real-world practice of the UroVysion test, demonstrating relatively low positive rate as compared to the previous reports from other countries. Further clinical evidence from other Japanese institutes needs to be accumulated to update the true value of this test. Clinical evidence of the UroVysion® urine test for surveillance of non-muscle invasive bladder cancer with carcinoma in situ remains limited. This study was the first to report the Japanese real-world practice of this test. Our findings will serve as a benchmark for future researches.
