Objectives:
To evaluate the efficacy and safety of 2 micron continuous wave laser resection of non-muscle-invasive bladder tumor (NMIBT) compared with holmium laser resection of bladder tumor (HoLRBT) and standard transurethral resection of bladder tumor (TURBT).
Methods:
Since April 2006 to August 2007, 97 patients with NMIBT were retrospectively collected in this study. All of them were classified into 3 groups, which were treated with 2 micron continuous wave laser resection, holmium laser resection and TURBT, respectively. The preoperative, intraoperative and postoperative clinical data were recorded and compared using SAS 6.12 statistical software.
Results:
There were no differences with the preoperative characteristics among the three groups, except the diameter of the tumors. The maximum diameter of the tumors in 2 micron laser group was larger than the other two groups (P < 0.05). Two micron laser group was associated with less hemoglobin decrease compared with TURBT group (P < 0.05). All of the patients were followed and the recurrence rate of the three groups indicated no statistical significance (P > 0.05).
Conclusions:
In conclusion, 2 micron continuous wave laser resection of non-muscle-invasive bladder tumor is a safe and reliable treatment. With the distinguished hemostasis, it is an available optional treatment.
