V8-12: En bloc thulium laser resection of bladder tumors: indications, surgical tips, and 3-yr oncologic outcomes
Video
INTRODUCTION
To describe surgical tips of en bloc bladder tumor resection with thulium laser and to report perioperative and oncologic outcomes of a single-center series.
METHODS
Data about 146 patients who underwent this technique were collected. The video highlights surgical tips of this technique in 4 different clinical scenarios. Perioperative outcomes and 3-yr oncologic outcomes were reported._x000D_
RESULTS
Mean operative time was 26.6 minutes, mean hospital stay was 1.6 days. The overall complication rate was 5%. No grade 3 Clavien complication occurred. Obturator reflex was never observed. 3-yr recurrence free survival rate for Ta low grade tumors and papillary urothelial neoplasms of low malignant potential was 78.5%. The 3-yr recurrence free survival rate for T1 high grade tumors with a negative ReTURB was 80%.
CONCLUSION
Preliminary results suggest that en bloc thulium laser resection of bladder tumors is a safe and oncologically effective technique. Thulium laser allows surgeon to perform resection without obturator reflex and to spare ureteral orifices, making tumors laterally located and those involving the ureteral orifice the best targets for this technique.
