A second transurethral resection (TUR) has been recommended by guidelines for high-grade non-muscle-invasive bladder cancer (NMIBC). However, the impact of surgical quality and post-TUR intra-vesical instillation therapy on oncologic outcome still remains unclear for newly diagnosed NMIBC. We conducted a retrospective cohort study for the patients who underwent extensive TUR followed by appropriate intra-vesical therapy for newly diagnosed NMIBC to assess their oncological outcomes. ⋯ While the present study has several limitations, including single-arm and retrospective nature, a single but extensive TUR combined with adjuvant intravesical treatment may have acceptable oncological outcomes in NMIBC patients.
