For the 2010 International Consultation on Urethral Strictures, all available published data relating to the evaluation and follow-up of patients with anterior urethral stricture or posterior urethral stenosis were reviewed and evaluated. Selected manuscripts were classified by Level of Evidence using previously established criteria. Consensus was achieved through group discussion, and formal recommendations were established and graded on the basis of levels of evidence and expert opinion. Retrograde urethrography remains the de facto standard for the evaluation of patients with urethral stricture. It can readily be combined with voiding cystourethrography to achieve a synergistic evaluation of the entire urethra, and this approach is currently recommended as the optimal method for pretreatment staging. Cystoscopy is recommended as the most specific procedure for the diagnosis of urethral stricture and is a useful adjunct in the staging of anterior urethral stricture, particularly to confirm abnormal or equivocal findings on imaging studies. Cystoscopy is also an important modality for assessing the bladder neck and posterior urethra in the setting of a pelvic fracture-related urethral injury. Although urethrography and cystoscopy remain the principle forms of assessment of the patient with urethral stricture, additional adjuncts include uroflowmetry, symptom scores, quality of life assessments, ultrasonography, computed tomography, and magnetic resonance imaging. These modalities might be helpful to further evaluate patients in select circumstances or provide a less invasive approach to monitoring outcomes after surgical treatment. Further research is needed to establish consensus opinion as to the definition of success after urethroplasty and to develop standardized patient outcome measures.
