3 randomized controlled trials (RCTs) comparing CBI (saline or water) vs. perioperative chemotherapy detected no differences in the modalities to prevent NMIBC recurrence. Dr. Sengupta et al. then performed in vitro investigation of cell viability when exposed to common bladder irrigants (water, saline, glycine). Water led to rapid cell lysis, with no detectable cells remaining by 10-20 minutes, compared to saline and glycine which were associated with a slower loss in cell viability. This promising data needs in vivo characterization in terms of efficacy as well as cost and tolerability compared to perioperative chemotherapy.
