Introduction: The standard non-muscle invasive bladder cancer (NMIBC) endoscopic diagnosis suffers from the frequently unsatisfactory white light evaluation accuracy leading to residual lesions being left behind. Monopolar transurethral resection of bladder tumors (TURBT) is marked by a substantial morbidity rate requiring further amelioration.
Methods: Small size tumors (under 1 cm) are feasible for "en bloc" resection. Bipolar TURBT was defined as being able to challenge the gold-standard status of monopolar resection due to the reduced complication rates. Plasma-button vaporization was introduced as a promising large bladder tumors' ablation modality. Narrow band imaging (NBI) cystoscopy became an increasingly popular method of enhancing tumor detection.
Results: The "en bloc" resection of small size or thin pedicle tumors provides the conditions for avoiding tumoral tissue scattering. Bipolar resection is characterized by decreased perioperative bleeding risks and faster patient recovery. Plasma-button vaporization gained confirmation as an innovative approach, able to dispose large tumor bulks under complete control while minimizing the associated morbidity. NBI cystoscopy is a useful tool in identifying CIS lesions, small papillary tumors or extended margins of large tumor formations. As a cost-free technique, it may be extensively used both during the NMIBC initial diagnostic as well as during follow-up evaluation protocol.
Conclusions: Having in mind the various modalities of ameliorating the bladder cancer diagnostic and treatment, NMIBC management should be tailored in accordance with the particularities of each case.

Background & Purpose: Narrow Band Imaging (NBI), developed by Olympus Medical Systems, has played a role in diagnosing digestive tract lesions and cancers, diagnosing and characterizing bladder cancers during cystoscopy and in the diagnosis and management of Head and Neck cancers. We aim to explore the potential use of NBI in the diagnosis, management, and follow-up of sinonasal tumours.
Methods: We present a series of cases treated at our institution, where NBI played a crucial role in the diagnosis, surgical management, intraoperative decision-making, and follow-up.

Background: In the present study, we compared Narrow Band Imaging (NBI) and White Light Cystoscopy (WLC) in Non-muscle invasive bladder cancer (NMIBC) for detection and its impact on recurrence.
Materials And Methods: This prospective study was conducted in the department of Urology at a tertiary institution from August 2021 to April 2023. The main aim was to determine the benefit of addition of NBI during TURBT in NMIBC.

Diagnosing urothelial cancer (UCa) via invasive cystoscopy is painful, specifically in men, and can cause infection and bleeding. Because the UCa risk is higher for male patients, urinary non-invasive UCa biomarkers are highly desired to stratify men for invasive cystoscopy. We previously identified multiple DNA methylation sites in urine samples that detect UCa with a high sensitivity and specificity in men.

Background: This review aims to compare the efficacies of fluorescence cystoscopy, narrow-band imaging (NBI), and white light cystoscopy in the treatment and diagnosis of bladder cancer.
Methods: The authors searched PubMed, EMbase, Web of Science, and the Cochrane Library from January 1990 to April 2022. A total of 26 randomized controlled studies and 22 prospective single-arm studies were selected.
