Abstract
An old consensus from WHO experts recommended the term “stricture” be used for the anterior urethra in cases with intrinsic corpus spongiosum fibrosis (spongiofibrosis) while the urethra remains in continuity. Conversely, they recommended the terms “stenosis” for the posterior urethra, and especially the term “sphincter stenosis” for simple continuity strictures of the membranous urethra (such as those from TURP or secondary to inflammations) or for those occurring after radical prostatectomy and urethra-vesical anastomosis, in order to emphasize that the distal urethral sphincter mechanism has not been destroyed although its function might be generally impaired to a variable extent. When there are more serious injuries of the posterior urethra (such as those arising from a pelvic fracture), the term “PFUDD” (pelvic fracture urethral distraction defects) was preferred [1].
