Abstract
BackgroundSeveral approaches for urethral catheterization after the failure of initial urethral catheterization have been introduced. However, standard procedures regarding what should be done after failed conventional urethral catheterization have been not established. Therefore, we investigated the clinical efficacy of retrograde urethrography (RGU)-assisted urethral catheterization after failed conventional urethral catheterization.MethodsBetween July 2015 and July 2018, 136 patients who underwent RGU-assisted urethral catheterization after failed conventional urethral catheterization were included in this retrospective study. Patients’ clinical data, such as age, catheterization site, and previous history of urologic operations, were collected and assessed via chart review. Univariate and multivariate logistic regression analyses were performed to identify predictive factors for the failure of this procedure.ResultsOf the 136 patients, 94 (69.1%) experienced successful RGU-assisted urethral catheterization. Having a previous history of urologic operations, such as urethrotomy and transurethral prostatectomy, was identified as an independent predictive factor for the failure of RGU-assisted urethral catheterization (odds ratio = 9.453, 95% confidence interval = 2.703–33.063, p < 0.001).ConclusionsRGU-assisted urethral catheterization can be one of the modalities for providing successful catheterization after failed conventional urethral catheterization. We believe that RGU-assisted urethral catheterization can be an effective procedure if patients have no previous history of urologic operations, such as urethrotomy and transurethral prostatectomy.

Summary
Several approaches for urethral catheterization after the failure of initial urethral catheterization have been introduced. Standard procedures regarding what should be done after failed conventional urethral catheterization have been not established. We investigated the clinical efficacy of retrograde urethrography (RGU)-assisted urethral catheterization after failed conventional urethral catheterization. Urethral catheterization is one of the most common urologic procedures. For various reasons, this procedure is performed on about a quarter of inpatients [1]. Clinicians are sometimes faced with unexpected difficulties during urethral catheterization (DDUCs). DDUCs are not common, if this is not properly handled, Further, there are many factors that can cause failed catheterization [6]. Common causes of DDUCs for normal urethras include tight external sphincters caused by anxiety in patients and poor catheterization technique.
