Low Grade

Based on the unmet clinical need to reduce invasiveness of treatment of low grade NMIBC, the investigators conduct this prospective, open label, single arm and single center phase II trial. The investigators aim to use drug screens in PDOs to guide neoadjuvant intravesical instillation therapy with either Epirubicin, Mitomycin C, Gemcitabine or Docetaxel to achieve chemoresection NMIBC.
