Introduction

The purpose of this study was to evaluate the safety and short-term outcome of laser en bloc enucleation using the The RevoLix(TM) 2??m continuous wave (CW) laser in the treatment of nonmuscle-invasive bladder cancer (NMIBC).

Methods

From October 2015 to March 2016, 28 patients (19 males and 9 females) with a single papillary NMIBC were selected for 2 ?m CW laser en bloc enucleation. The mean tumor diameter was 1.8 cm (range 0.5-4.0 cm). We used glass rinsing bottle to obtain the en bloc tumor. Peri-operative data and oncological results were retrospectively collected.

Results

All surgeries were successfully completed. There was no major complication such as bladder hemorrhage, vesicle perforation, or obturator nerve reflex occurrence during the operation. Mean operative time was 26.7 minutes (range 16-37 minutes). No significant intraoperative or postoperative bleeding occurred in all cases. The stages of bladder cancer included 15 Ta and 13 T1. With the 6 to 12 months follow-up, no tumor recurrence was observed.

Conclusions

The 2??m CW laser en bloc enucleation is a safe and effective option for the treatment of NMIBC. All the different intravesical sites of the NMIBC can be enucleated with 2??m CW laser. Moreover, it may improve the accurate valuation of tumor stage. Although the long-term outcomes are still unknown, the short-term oncological outcomes are satisfactory.
