OBJECTIVE To describe the value of flexible cystoscopy versus conventional urethrography (retrograde urethrography and cystourethrography) in diagnosing pelvic fracture urethral distraction defects (PFUDDs). PATIENTS AND METHODS Between May 2010 and June 2011, 120 male patients with PFUDDs were evaluated. In this study, all patients underwent conventional urethrography after admission. Flexib...

OBJECTIVE To evaluate and analyse the efficacy of computed tomography (CT) virtual cystoscopy in comparison to conventional cystoscopy for the follow-up of patients with non-muscle-invasive bladder cancer. PATIENTS AND METHODS The study was done over 3 years, from April 2010 to June 2013, and included 30 patients who all had non-muscle-invasive transitional cell carcinoma (Ta, T1). The patien...

Hexaminolevulinate HCl is a diagnostic imaging agent used with blue light during cystoscopy to help detect non-muscle-invasive bladder cancer. Blue light cystoscopy performed using hexaminolevulinate HCl has been found to detect more papillary non-muscle-invasive bladder tumors than cystoscopy performed using standard white light. Because bladder instillation and retention requirements of hexam...

In the past three decades, the use of smart methods in medical diagnostic systems has attracted the attention of many researchers. However, no smart activity has been provided in the field of medical image processing for diagnosis of bladder cancer through cystoscopy images despite the high prevalence in the world. In this paper, a multilayer neural network was applied to clas...

CONTEXT At least 50% of patients with a history of bladder cancer have recurrences, so rigorous surveillance is necessary. Cystoscopy is standard but can fail to detect some bladder cancers, so a urine test is frequently part of the evaluation. OBJECTIVE To investigate whether a point-of-care proteomic test that measures the nuclear matrix protein NMP22 in voided urine could improve detection...

A healthy 54 year old man was investigated for haematuria. In spite of a proven urinary tract infection a cystoscopy was carried out with no antibiotic therapy. As a result he developed systemic infection leading to two independent, and potentially fatal, complications: vertebral osteomyelitis and a mycotic false aneurysm.

Background: Bladder urothelial carcinoma has high recurrence rate so patients with bladder urothelial carcinoma have to be monitored thoroughly for disease recurrence, this makes bladder cancer one of the most expensive cancer types for the health care system. Voided urine cytology is the most commonly used noninvasive follow-up diagnostic tool. The purpose of this study was to assess the role ...

INTRODUCTION Several studies, including the recently published phase III study by Stenzl and colleagues have demonstrated that hexaminolevulinate hydrochloride, when used with blue light fluorescence cystoscopy, improves detection of non-muscle invasive bladder tumors compared to white light cystoscopy and transurethral resection of bladder tumors (TURB) alone. MATERIALS AND METHODS The objec...

BACKGROUND Fluorescence photodynamic diagnosis (PDD) cystoscopy is gaining credence in the diagnosis and surveillance of bladder cancer. It combines normal white light cystoscopy with periodic blue light examination of the bladder pre-instilled with a tumour selective porphyrin, hexa-aminolevulinic acid (hexa-ALA).1 This method detects areas of fluorescent tissue suggestive of tumour or carcino...

Narrow band imaging (NBI) is a newly developed technology aiming to provide additional endoscopic information for patients with bladder cancer. This review focuses on the diagnostic accuracy and treatment outcome using NBI cystoscopy for the treatment of non-muscle invasive bladder cancer. Current results showed improved sensitivity of NBI cystoscopy compared to conventional white light cystosc...
