However, the technique harbors some serious disadvantages facilitating tumor recurrence. Recently, the use of lasers to treat bladder tumors is emerging. Here, we reported a novel tumor en bloc enucleation technique with a front-firing Green-light KTP laser and present our initial clinical experience. Methods From March through July 2013, a total of 35 patients with NMIBC underwent transurethral resection with our modified technique using 30 W front-firing Green-light KTP laser in our hospital. En bloc enucleation was applied on all of the tumors. Preoperative and intraoperative data were prospectively collected. The follow-up included urine analysis, ultrasonography and cystoscopy every 3 months. Results All patients were treated successfully with front-firing Green-light KTP laser enucleation of bladder tumors under spinal anesthesia in one session, with no bladder haemorrhage, obturator nerve reflex or vesicle perforation. The mean (range) tumor diameter was 1.8 (0.3-3) cm. Mean operative and enucleation times were 21 (12-38) and 12 (4-23) min, respectively. Mean serum hemoglobin decrease was 1.1 (0.1-2.4) mg/dl. Mean catheter time was 2.0 (1.0-3) days and mean postoperative hospital stay was 2.5 (1.5-4) days. The entire lamina propria and detrusor muscle was well preserved in all specimens, and the stage of bladder cancers was 18 Ta, 14 T1 and 3 T2a after pathohistological examination. No tumor recurrence was observed after 3 months follow-up. Conclusions The modified technique using front-firing Green-light KTP laser to en bloc enucleate bladder tumor is effective and safe when treating NMIBC under local anesthesia. Moreover, it improves the accurate valuation of tumor stage and prediction of postoperative prognosis. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e563-e564 Advertisement Copyright & Permissions© 2014MetricsAuthor Information Da-lin He More articles by this author Jin-hai Fan More articles by this author Kai-jie Wu More articles by this author Da-peng Wu More articles by this author Xin-yang Wang More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
