Submucosa dilation assisted laser resection of bladder tumor for the treatment of solitary non-muscle invasive bladder cancer: initial experience / 中华泌尿外科杂志

ABSTRACT

ObjectiveTo evaluate the safety and efficacy of submucosa dilation assisted laser resection of bladder tumor for the treatment of solitary non-muscle invasive bladder cancer. MethodsA total of 12 patients with solitary non-muscle invasive bladder tumor were treated with the procedure of submucosa dilation assisted laser resection under total intravenous anesthesia or epidural anesthesia.lntravesical instillation chemotherapy was performed according to CUA 2007 guidelines.Patients were followed up for 4 - 36 months after the operation. ResultsThe diameter range of the tumors was 0.5 - 2.3 cm with the clinical stage Ta - T1 and low pathology grade.Submucosa dilation assisted laser resection of bladder tumor was successfully performed on all patients.The average operation time was 25 min (range,20 -45 min ),and the catheter time was 3 d ( range,1 -4 d).The mean volume of bleeding was less than 5 ml,no patient required blood transfusion.No complications such as obturator nerve reflex,bladder perforation and over-hydration occurred.No recurrence occurred during the follow-up. ConclusionsSubmucosa dilation assisted laser resection of bladder tumor could be an effective,safe,and excellent alternative procedure for the treatment of solitary non-muscle invasive bladder cancer,with few complications and a low recurrence rate.More studies and long-term follow-up should be warranted to ultimately evaluate this procedure.
