The use of uroflowmetry to diagnose recurrent stricture after urethral reconstructive surgery

Abstract

on the other side. Should this case be considered pT2c? In this particular example what should be a minimum extent for a case to be considered bilateral? During the consensus conference there was no consensus regarding definition of index tumor, and the minimum size for a second tumor to be considered for the whole case to be classified as pT2c.Overview of the literature indicates that current pathological T2 substaging criteria lack clinical relevance and the majority of conference attendees wished to discontinue pT2 substaging. Therefore, the consensus was that reporting of pathological T2 substages should, at present, be optional. Purpose: The ability of uroflowmetry to diagnose recurrent stricture disease after urethroplasty has not been fully investigated. Materials and Methods: Our routine post-urethroplasty monitoring includes retrograde urethrogram and voiding cystourethrogram at 3 and 12 months, in addition to uroflowmetry at 3-month intervals for a year. All uroflowmetry data, including maximum flow rate, voided volume and voiding curve shape, as well as retrograde urethrogram/voiding cystourethrogram and voiding symptom data are stored in a prospectively maintained urethroplasty database that was analyzed for patients with postoperative retrograde urethrogram/voiding cystourethrogram and satisfactory uroflowmetry in the same period.

Patient-Reported Outcome Measures in Urethral Reconstruction

“…It has never been validated as a stand-alone tool for recurrence screening; however, when these voiding curves were combined with patient-reported symptoms, it has demonstrated 51% sensitivity, 98% specificity, 90% positive predictive value, and 86% negative predictive value. [9] Morey et al were first to use the American Urological Association Symptom Score (AUA-SS) in correlation with uroflowmetry and retrograde urethrogram findings to predict recurrence of USD. [10] In a prospective report, Heyns et al has combined uroflow with AUA-SS and demonstrated 68% specificity for initial diagnosis of USD but its role in the postoperative setting is unknown.…”
