In light of recently published international guidelines concerning the diagnosis, treatment, and aftercare of urethral strictures and stenoses, the objective of this study was to synthesize an overview of guideline recommendations provided by the American Urological Association (AUA, 2023), the Société Internationale d'Urologie (SIU, 2010), and the European Association of Urology (EAU, 2023). The recommendations offered by these three associations, as well as the guidelines addressing urethral trauma from the EAU, AUA, and the Urological Society of India (USI), were assessed in terms of their guidance on posterior urethral stenosis. On the whole, the recommendations from the various guidelines exhibit considerable alignment.
