Comparison of GreenLight Laser Photoselective Vaporization and Thulium Laser Enucleation for Nonmuscle Invasive Bladder Cancer.
OBJECTIVE
To evaluate the safety and efficacy of GreenLight laser vaporization and thulium laser enucleation for nonmuscle invasive bladder cancer (NMIBC).


PATIENTS AND METHODS
A total of 150 patients of NMIBC who underwent either GreenLight laser vaporization (Group A, n = 78) or thulium laser enucleation (Group B, n = 72) were analyzed, respectively. The preoperative, intraoperative, and postoperative clinical data were recorded and compared in the two groups.


RESULTS
All patients were successfully treated with GreenLight laser vaporization or thulium laser enucleation. No significant difference was observed in operation time, catheterization time, and postoperative hospital stay time between them. No complications such as obturator nerve reflex, bladder perforation, overhydration, or intraoperative or postoperative bleeding occurred in all patients. The patients were followed up for 12 months; during the period the recurrence rate was 10.26% (8/78) and 9.72% (7/72), respectively, between Groups A and B.


CONCLUSIONS
Both GreenLight laser vaporization and thulium laser enucleation are effective and safe treatments for patients with NMIBC. Long-term clinical trials are necessary to increase the current scientific evidence base.
