Comparison Of Greenlight Laser Photoselective Vaporization And Thulium Laser Enucleation For Non-muscle-invasive Bladder Cancer

ObjectiveTo evaluate the safety and efficacy of Greenlight Laser Vaporization and Thulium Laser Enucleation for non-muscle-invasive bladder carncer(NMIBC).MethodsOne hundred and fifty 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.ResultsAll patients were successfully treated with Greenlight Laser Vaporization or Thulium Laser Enucleation.No significant difference was observed in operation time,the decrease of serum hemoglobin and catheterization 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 Group A and B.ConclusionsBoth 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.
