Photodynamic diagnosis (PDD) improves the detection of non-muscle-invasive bladder cancer (NMIBC). However, white-light (WL) cystoscopy remains the technique routinely used in urological clinics. A more cost-effective but equally performant alternative to PDD may encompass the use of an intense tumoritropic dye in combination with WL cystoscopy. Using a preclinical setting, we investigated the ...

Colovesical fistulae typically present with pneumaturia and/or fecaluria. Diverticulitis, inflammatory bowel disease, and malignancies of the colon are the commonest causes. The fistulous tract and adjacent organs are best demonstrated by contrast-enhanced CT scan with rectal contrast or MRI. Biopsy at cystoscopy/colonoscopy is necessary for complete evaluation and treatment planning.

Computed tomography (CT) based virtual cystoscopy (VC) has been studied as a potential tool for screening bladder cancer. It is accurate in localizing tumor of size larger than 1 cm and less expensive, as compared to fiberoptic cystoscopy. However, it is invasive and difficult to perform due to using Foley catheter for bladder insufflating with air. In a previous work, we investigated a magneti...

Background: Reducing temperature of topically applied lignocaine gel for maximal anesthesia during cystoscopy in conscious patients have yielded mixed results. This prospective randomised controlled study was undertaken to compare pain mitigating effect at 4°C versus room rigid male patients. Methods: The consists 126 consecutive (n=126) who were randomly assigned into two groups: Group 1 (cont...

OBJECTIVE To evaluate the efficacy of narrow band imaging (NBI) cystoscopy associated with bipolar plasma vaporization (BPV) in cases of large nonmuscle-invasive bladder tumors (NMIBTs) compared with white light cystoscopy (WLC) and monopolar transurethral resection of bladder tumors (TURBTs). METHODS A total of 220 cases with ≥ 1 bladder tumor >3 cm determined by abdominal ultrasonography, c...

PURPOSE The analgetic efficacy of intraurethral instillation of anesthetic jelly in rigid cystoscopic examination for men is not clearly confirmed. This study evaluated the usefulness of intraurethral instillation of anesthetic jelly by questionnaires regarding the pain and uncomfortable feelings during and after the cystoscopic examination. MATERIALS AND METHODS A total of 62 men were enroll...

OBJECTIVE To assess the use of urologic investigations among traumatic spinal cord injury (TSCI) patients. METHODS This is a retrospective cohort study from Ontario, Canada. We included all adult TSCI patients injured between 2002 and 2012. The primary outcome was the frequency of urodynamic testing, renal imaging, and cystoscopy. Primary exposure was the year of injury. The impact of age, se...

PURPOSE The aim of this study was to evaluate the efficacy and safety of hexaminolevulinate fluorescence cystoscopy in the diagnosis of bladder cancer. MATERIALS AND METHODS In a prospective design, we included patients who had a bladder lesion suggesting bladder cancer. Patients with massive hematuria, urethral Foley catheter insertion, chronic retention state, or urinary tract infection wer...
