New laser technique may improve bladder cancer surgery outcomes

This study compared two surgical techniques for removing early-stage bladder tumors: a new laser method (holmium laser en-bloc resection) and the standard approach (conventional transurethral resection). 100 adults with suspected non-muscle-invasive bladder cancer were randomly assigned to one of the two procedures. The goal was to see which method provides better quality tumor samples and fewer side effects like bleeding or bladder perforation.
