Sterile versus non-sterile gloves during cystoscopy: A randomized prospective single-blind study.

Abstract

The objective of this study is to evaluate the need for sterile gloves during cystoscopy by comparing the incidence of UTI symptoms between patients in whom the procedure is performed with non-sterile gloves with those performed with non-sterile gloves. This study had a randomized, prospective, single-blind design and included patients aged >20 years who underwent cystoscopy in either of two outpatient clinics between September 2015 and November 2021. The patients were allocated to a sterile group or a non-sterile group. Only the urologists were aware of whether or not the gloves were sterile. The patients were instructed to report any symptoms suggestive of UTI after cystoscopy. A total of 1258 patients were enrolled in the sterile group and 1376 in the non-sterile group. Symptoms of UTI were reported by six patients (0.48%) in the sterile group and six (0.44%) in the non-sterile group. The between-group difference was not statistically significant (p = 0.88). It is not necessary to use sterile gloves during routine cystoscopy.
