Objective To determine whether¯exible cystoscopy with a prototype slim¯exible instrument is less uncomfortable than¯exible cystoscopy using a standard exible cystoscope. Patients and methods In all, 200 men scheduled to undergo¯exible cystoscopy for the follow-up of transitional cell carcinoma of the bladder were randomized in equal groups to¯exible cystoscopy using the standard instrument or using the prototype slimscope. Each patient had 11 mL of 2% lignocaine gel instilled intraurethrally 5 min before the procedure. At the end of the procedure the patient was asked to complete a 100-mm non-graphical visual analogue scale to rate how uncomfortable the procedure was. Results The slim-scope was very signi®cantly less uncomfortable than the conventional instrument (ANOVA P<0.001). The ease of use and views of the bladder were similar to those obtained with the conventional cystoscope. Conclusion The slim-scope offers a signi®cant bene®t in patient comfort, with little loss of image quality or ease of use.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
