Supplementary Material for: Management of Anterior Urethral Strictures in Adults: A Survey of Contemporary Practice in Germany

<i>Introduction:</i> Treatment methods of anterior urethral strictures in adults have undergone considerable changes in the recent past. Our goal was to determine national practice patterns among German urologists and to compare results with the results of prior international surveys. <i>Methods:</i>We conducted a survey on the management of urethral strictures among German urologists. <i>Results:</i> Eight hundred forty-five urologists, representing about 14.6% of German urologists, answered the survey. Most common procedures were direct vision internal urethrotomy (DVIU; 87.2%), blind internal urethrotomy (57.5%), dilatation (56.3%), ventral buccal mucosa graft urethroplasty (31.6%) and excision and primary anastomosis (28.9%). In case of a 3.5-cm bulbar stricture and in the case of a 1-cm bulbar stricture after 2 failed DVIUs, a consecutive urethroplasty was significantly more often favoured compared to transurethral treatment options (44.9 vs. 21.3% and 59.4 vs. 8.3%, both <i>p</i> < 0.001). <i>Conclusion:</i> Open urethral reconstruction reveals to be a more common method in practice nowadays. Adherence to recommended treatment algorithms improved in comparison to prior surveys.
