Anastomotic urethroplasty

Although the commonest forms of injury are instrumental or other iatrogenic injuries, most of which are internal, these usually cause long strictures of ≥ 2 cm, for which AU is not usually appropriate. The typical injury of the bulbar urethra causing a stricture for which AU is appropriate is a fall-astride injury which crushes the bulbar urethra against the underside of the pubic symphysis. In most instances, this causes fibrotic obliteration of a short segment of the bulbar urethra, but can sometimes cause complete loss of continuity and significant loss of length of the bulbar urethra.
