ABSTRACT
OBJECTIVES:
The aim of our study was to evaluate the efficacy and safety of a newly introduced endoscopic technique in the treatment of non-muscle invasive bladder cancer (NMIBC), the bipolar plasma vaporization of bladder tumors (BPV-BT). MATERIALS ANDMETHODS:
Between May and November 2009, 72 consecutive patients presenting papillary bladder tumors over 1 cm underwent BPV-BT and a 3 months follow-up. Initial biopsy followed by plasma vaporization of the tumor and biopsies of the tumoral bed were performed in all cases. The follow-up protocol included abdominal ultrasonography, urinary cytology and cystoscopy at 3 months.RESULTS:
BPV-BT was successfully performed in all cases. Multiple tumors were found in 45.9% and tumors over 3 cm in 33.3% of the cases. The mean tumoral volume was 10.5 ml. The mean operative time was 16 minutes, the mean hemoglobin decrease was 0.4 g/dl, the mean catheterization period was 2.3 days and the mean hospital stay was 3.4 days. There was no major intra- or postoperative complications. The pathological exam diagnosed 58.3% pTa, 30.6% pT1 and 11.1% pT2 cases. No tumoral base biopsies were positive for malignancy. The recurrence rate was 15.6% for the NMIBC patients, 13.3% for patients with single tumor under 3 cm and 16.3% in cases of single tumors over 3 cm or multiple tumors. Orthotopic recurrent tumors were encountered in 3.1% of the cases.CONCLUSIONS:
BPV-BT seems to represent a promising endoscopic treatment alternative for NMIBC patients, with good efficacy, reduced morbidity, fast postoperative recovery and satisfactory follow-up parameters.
