“…[166][167][168][169] Similarly, several randomized trials have evaluated narrow band imaging (NBI) and demonstrated improved cancer detection rate compared to WLC. [170][171][172][173] Both NBI and PDD have shown increased tumour detection and decreased recurrences compared to WLC TUR. However, impact on long-term recurrences and progression has not been demonstrated.…”

This initiative was undertaken in response to concerns regarding the variation in management and in outcomes of patients with bladder cancer throughout centres and geographical areas in Canada. Population-based data have also revealed that real-life survival is lower than expected based on data from clinical trials and/or academic centres. To address these perceived shortcomings and attempt to streamline and unify treatment approaches to bladder cancer in Canada, a multidisciplinary panel of expert clinicians was convened last fall for a two-day working group consensus meeting. The panelists included urologic oncologists, medical oncologists, radiation oncologists, patient representatives, a genitourinary pathologist, and an enterostomal therapy nurse. The following recommendations and summaries of supporting evidence represent the results of the presentations, debates, and discussions. Methodology

“…No differences in clinical outcomes were appreciated between resection methods. In the study by Geavlete et al [9], the patients with NMIBC underwent resection using narrow band imaging cystoscopy and bipolar cautery. The control group underwent resection using traditional white light cystoscopy and monopolar cautery.…”

“…Using the results of a study carried out by Geavlete et al [9], which compared monopolar and bipolar treatment efficacy in NMIBC, the sample size required for the measurement of each group was calculated to be 106 subjects with 0.95 power value and 0.05 error. To achieve this, we estimated that we would need to recruit 120 patients per arm.…”

Objective: We aimed to compare the safety and efficacy of monopolar and bipolar transurethral resection (TUR) of bladder tumors (TURBTs). Material and Methods: A total of 240 patients who underwent TURBT were prospectively included in the study from May 2011 to May 2014. All patients with suspected bladder tumors were eligible for study inclusion. Those who refused consent and those undergoing routine restaging TURBT were excluded from analysis. Patients were divided on the basis of the monopolar arm and the bipolar arm. Study outcomes included the incidence of bladder perforation and obturator jerk, decrease in hemoglobin and sodium levels, rates of re-coagulation and blood transfusion, TUR syndrome, and operation time. Results: The mean age of the patients was 62 ± 13.7 years. The incidence of obturator jerk and bladder perforation was greater in the bipolar arm. However, with a decrease in the hemoglobin and sodium levels, rates of re-coagulation and blood transfusion were greater in the monopolar arm. Statistical analysis did not show significant differences with regard to study outcomes between the groups. There was no case of TUR syndrome in the 2 arms. The residual tumors' rate was similar between the 2 groups. Conclusions: Our results showed that efficacy and safety of the monopolar and bipolar methods seems to be comparable in patients with bladder tumors.

“…In der Nachresektion fanden sich nach NBI und bipolarer Resektion im Vergleich zur Weißlichtzystoskopie und monopolaren Resektion insgesamt weniger Residualtumoren (6,3% vs. 17,5%) sowie auch weniger Residualtumoren am primären Resektionsgebiet (4,2% vs. 13,4%). Nach einem Jahr lag die Rezidivrate bei 7,9% in der NBI-Gruppe im Vergleich zu 17,8% in der Weißlichtgruppe [11]. …”

Narrow band imaging (NBI) is an optical diagnostic procedure which utilizes the narrowing of the wavelength of visible light in the range between 415 and 550 nm. The NBI is mostly used for the diagnostics of inflammation or tumors of the gastrointestinal tract. The first investigations for diagnostics of bladder cancer using NBI date from 2008. Currently data on resection, follow-up and recurrence behavior of bladder cancer are available. In all publications NBI was tested against white light. A randomized study comparing NBI with photodynamic diagnostics has not yet been carried out. In this article current study results on the application of NBI for bladder cancer will be presented.
