<b><i>Introduction:</i></b> The thulium laser resection of bladder tumors (TmLRBT) was increasingly used in the treatment of non-muscle-invasive bladder cancer (NMIBC) recently, and here we report the relevant outcomes of our institution to evaluate its efficacy and safety. <b><i>Methods:</i></b> We retrospectively collected the data of NMIBC patients who underwent either TmLRBT or transurethral resection of bladder tumor (TURBT). The baseline characteristics and perioperative outcomes were compared in these 2 groups. <b><i>Results:</i></b> The TmLRBT had a higher rate of detrusor identification than TURBT (97.4 vs. 87.6%, <i>p</i> = 0.001). After screening, 134 patients who underwent TmLRBT and 152 patients who received TURBT were enrolled in the analysis, and their baseline characteristics were similar. During the TURBT, 24 (15.8%) obturator nerve reflexes and 9 (5.9%) bladder perforations occurred, while none happened during the TmLRBT. After surgery, TmLRBT patients had fewer postoperative gross hematuria (38.1 vs. 96.7%, <i>p</i> &#x3c; 0.001) and postoperative irrigation (27.6 vs. 92.7%, <i>p</i> &#x3c; 0.001), and its irrigation duration was significantly shorter (2.3 vs. 3.3 day, <i>p</i> &#x3c; 0.001). During the follow-up, no significant difference in the recurrence rate was detected (<i>p</i> = 0.315). <b><i>Conclusions:</i></b> TmLRBT is a safer technique than conventional TURBT in the treatment of NMIBC, and it could offer better specimens for pathologic assessment while the cancer control was not compromised.

Background: Thulium laser resection of bladder tumors (TmLRBT) is recently considered as a common treatment option for non-muscle-invasive bladder cancers (NMIBC), but whether it is superior to Transurethral resection of bladder tumors (TURBT) are still undetermined.Materials and Methods: We retrospectively screened our institution database to identify patients who were treated by conventional TURBT or TmLRBT for NMIBC and followed by intravesical bacillus Calmette-Guérin (BCG) immunotherapy. The preoperative characteristics, perioperative outcomes, and recurrence-free survival were compared to assess the safety and efficacy of the two procedures.Results: Eventually, 90 patients who underwent TmLRBT (n = 37) or TURBT (n = 53) followed by intravesical BCG immunotherapy were included. Two groups were similar in baseline characteristics except for the smaller tumor size of the TmLRBT group(1.7 cm vs. 2.2 cm; P = 0.036). Obturator nerve reflex occurred in eight patients in the TURBT group and 3 of them suffered from bladder perforation while none happened in the TmLRBT group. The TmLRBT also had a shorter irrigation duration. In the multivariate Cox regression, the TmLRBT was related to less recurrence risk (HR: 0.268; 95% CI, 0.095–0.759; P = 0.013).Conclusion: Our results suggested that TmLRBT is safer than conventional TURBT with fewer perioperative complications, and it offers better cancer control, therefore might be a superior option for NMIBC patients with intermediate and high recurrence risk.
