Minimally Invasive Methods for Bulbar Urethral Strictures: A Survey of Members of the American Urological Association

ObjectiveTo determine current practice patterns, we mailed a questionnaire regarding urethral stricture evaluation, treatment, and follow-up to members of the American Urological Association (AUA). The minimally invasive methods used for treating and evaluating anterior urethral strictures vary widely among clinicians.MethodsA nationwide survey of practicing members of the AUA was performed by mailed questionnaires. Surveys were mailed to 1262 Urologists, randomly selected from all 50 states. Four-hundred thirty-one urologists (34%) completed the questionnaire and formed the basis for our analysis.ResultsMost urologists (63%) treat 6-20 urethral strictures per year. The most common minimally invasive procedures used for managing anterior urethral strictures were dilation (92.8%), cold-knife optical internal urethrotomy (85.6%), endourethral stent (23.4%), laser urethrotomy (19%), and periurethral steroid injection after urethrotomy (7.9%). Most urologists will perform urethrotomy on bulbar strictures up to 2 cm (68.7%) and leave a Foley catheter in place for 1 week or less (86.5%). Technical method of urethrotomy is commonly 1 cut at 12 o'clock (86.3%) or radial cuts (12.1%). Recommended follow-up diagnostic tests after urethrotomy included flow rate (62.9%) and, to a lesser degree (with roughly one-third each), cystoscopy, urethral calibration, and the International Prostate Symptom Score (IPSS). Other tests, such as ultrasonography or urethrography were rarely used.ConclusionOur survey provides information regarding current minimally invasive management and follow-up practice strategies recommended by members of the AUA for anterior urethral strictures. Many common practices in the treatment of anterior urethral stricture disease are not supported in the literature.
