OBJECTIVES Urine based tumor markers have uncertain utility in diagnosis or surveillance of patients with bladder cancer while cytology is commonly used. We evaluated whether cytology provides additional diagnostic information in patients with a negative NMP22® BladderChek® test (BladderChek) and negative cystoscopy. MATERIALS AND METHODS We performed subset analyses of 2 large prospective mu...

Both flexible and rigid cysto-urethroscopy are routinely used in the surveillance of transitional cell bladder tumours. This study addressed the issue of patient selection for either rigid or flexible cystoscopy. What proportion of positive findings at flexible cystoscopy and negative findings at rigid cystoscopy are acceptable? Standards were set of 10% for the former and 50% for the latter an...

PURPOSE The current literature shows mixed results for the effectiveness of topical intraurethral lidocaine gel as local anesthesia during flexible cystoscopy. We performed a meta-analysis of randomized, controlled trials of the efficacy of 2% lidocaine vs plain gel for decreasing the pain that male patients incur during flexible cystoscopy. MATERIALS AND METHODS A search of the literature fr...

BACKGROUND The aim of this study was to evaluate the role of flexible cystoscopy in preventing malpositioning of the ureteral stent after laparoscopic ureterolithotomy in male patients. METHODS From April 2009 to June 2015, 97 male patients with stones >1.8 cm in the upper ureter underwent intracorporeal double-J stenting of the ureter after laparoscopic ureterolithotomy performed by four dif...

INTRODUCTION The aim of this study was to investigate the feasibility of out-patient flexible cystoscopy. PATIENTS AND METHODS Twenty-seven patients awaiting diagnostic or check cystoscopy in Leeds, UK were invited to undergo out-patient flexible cystoscopy using a CST-2000 Flexible Cystoscope (Vision Sciences; Natick, MA, USA) using the sterile single-use slide-on(trade mark) disposable endo...

INTRODUCTION A prospective study to evaluate the reliability of cystoscopy was performed with fluorescence (photodynamic diagnosis, PDD) compared with standard white light (WL) cystoscopy in patients with solitary carcinoma in situ (CIS), undergoing BCG treatment. MATERIALS AND METHODS Between February 2004 and March 2006, 49 patients suffering from CIS were enrolled in the study. Patients ag...
