Abstract
BACKGROUND: The quality of transurethral resection of bladder tumor (TURBT) markedly varies among surgeons and may have a considerable impact on treatment outcomes. The importance of a surgical checklist for TURBT has been suggested in order to standardize the procedure and improve surgical and oncological outcomes. In the present study, we verified the usefulness of a checklist for managing patients with non-muscle-invasive bladder cancer (NMIBC). METHODS: This retrospective study included 201 NMIBC patients diagnosed with Ta, T1, or Tis between October 2011 and February 2021. After September 2016, TURBT was performed with a checklist. We analyzed the intravesical recurrence-free survival (RFS) rate and the presence or absence of the detrusor muscle in resected specimens before and after the introduction of the checklist. Survival rates were compared using the Log-rank test. A multivariate analysis with Cox proportional hazards modeling was performed to verify risk factors for intravesical recurrence. RESULTS: Ninety-nine patients who underwent TURBT with the checklist (checklist group) were compared with 102 patients who underwent TURBT without the checklist (non-checklist group). When the analysis was narrowed down to 9 critical items, we observed a mean number of 9 documented items per operative report (98.0% completion) after implementation of the checklist. Two-year intravesical RFS rates in the checklist and non-checklist groups were 76.7 and 69.5%, respectively (p = 0.1059). The Cox proportional multivariate analysis showed that the rate of intravesical recurrence was slightly lower in the checklist group (hazard ratio 0.7376, 95% CI 0.4064-1.3388, P = 0.3170). CONCLUSION: The introduction of a checklist is recommended for the standardization of TURBT and increasing the quality of operative reporting, and it may also improve oncological outcomes.
