Several single-center studies have investigated whether narrow-band imaging (NBI) cystoscopy is more effective in detecting primary and recurrent non-muscle invasive bladder cancer (NMIBC) compared with white-light imaging (WLI) cystoscopy. In this study, we further evaluated the diagnostic value of NBI cystoscopy compared with WLI cystoscopy for primary NMIBC in a multi-center study. Suspected...

PURPOSE To examine the value of surveillance urethro-cystoscopy in patients with neurogenic lower urinary tract dysfunction (NLUTD) in regard to the conflicting literature as it is generally agreed that patients with NLUTD are at increased risk for bladder cancer. MATERIALS AND METHODS In a cross-sectional study, a consecutive series of 129 patients (50 females, 79 males, mean age 51, range 1...

OBJECTIVE To demonstrate the various applications of CT-virtual endoscopy, for the assessment of urinary tract abnormalities. MATERIALS AND METHODS Sixty-three patients were evaluated by CT-virtual endoscopy (49 CT-cystoscopy; 14 CT-pyeloureteroscopy). CT-cystoscopy was obtained for follow-up of bladder tumor (n=21), radiologic suspicion (n=12) or radiologic evidence of urinary tract lesion (...

OBJECTIVES 1) To determine whether fluorescence cystoscopy after intravesical administration of 5-aminolevulinic acid (5-ALA) is more sensitive in detection of dysplasia and bladder cancer when compared with conventional cystoscopy. 2) To determine the safety of using 5-ALA. MATERIALS AND METHODS A 3% 5-ALA solution was instilled intravesically before cystoscopy in 41 patients. The 5-ALA-indu...

For patients with non-muscle invasive bladder cancer, cystoscopy and transurethral resection/vaporization of the bladder tumor plays an integral role in the treatment of a given patient's bladder cancer. Although considered the current gold standard for tumor detection, traditional or white light cystoscopy has been shown to have its limitations visualizing both small papillary tumors and/or ca...

PURPOSE We assessed the impact that improved detection of nonmuscle invasive bladder cancer with hexaminolevulinate fluorescence cystoscopy may have on early recurrence rates. MATERIALS AND METHODS This prospective, randomized study enrolled 814 patients suspected of having bladder cancer at increased risk for recurrence. All patients underwent white light cystoscopy and mapping of lesions, f...

The aim of this study was to describe the clinical features and long-term outcome of the patients who were treated at our institution for idiopathic urethrorrhagia. The data of 10 male patients, who underwent cystoscopy between October 2010 and March 2013 due to urethrorrhagia, were evaluated retrospectively. Ten male patients aged between 8 and 16 years at first submission. Four patients (40%)...

Bladder cancer (Bca) is one of the most common tumors in urinary system. Cystoscopy biopsy a gold standard for diagnosis Bca clinic. However, cystoscopy invasive, costly and invasive process causing pain patients. Because cells are closely contact with urine, exosomes can pass through base membrane transport microRNA (miRNAs) to so detection exosome-derived miRNAs urine expected be new non-inva...
