Pelvic fracture urethral injury (PFUI) is disruption of the posterior/bulbomembranous urethra caused by severe pelvic trauma. The patient may have blood at the urethral opening and be unable to pass urine. Acute treatment prioritises life-threatening injuries and safe bladder drainage; a suprapubic catheter or carefully performed urethral drainage may be used, and early endoscopic realignment can be considered when feasible. Complete disruptions commonly heal as an obliterative scar. Definitive treatment is usually delayed perineal anastomotic urethroplasty after recovery from the pelvic injury.

What happens to the urethra in a pelvic fracture?

Pelvic-ring movement can stretch or tear the urethra where the mobile bulbar urethra meets the fixed membranous segment. In severe injuries the two urethral ends separate, with a pelvic haematoma and later fibrosis filling the gap.

Symptoms and signs in the acute injury

• Blood at the urethral opening.
• Inability to urinate.
• Pelvic fracture on trauma imaging.
• Perineal or scrotal bruising.
• Difficulty passing a catheter.

What should happen before repeated catheter attempts?

When PFUI is suspected, urethral assessment should be performed by an experienced team. EAU trauma guidance supports flexible cystoscopy and/or retrograde urethrography. If catheter passage is difficult, force should not be used; suprapubic drainage is an accepted alternative.

Initial management options

Why wait before definitive urethroplasty?

After roughly three months, the pelvic haematoma has largely resolved, scar tissue has matured and the patient is usually able to tolerate reconstructive positioning. The prostate and urethral ends are easier to define. This makes a precise tension-free repair more predictable than operating through acute injured tissue.

How is PFUI mapped before surgery?

A combined RGU and MCU/VCUG defines the distal urethra, proximal urethra and apparent distraction gap. Antegrade cystoscopy through the suprapubic tract can assess the bladder neck and proximal urethra, and can identify stones, fistulae or false passages. The radiographic “gap length” is useful but does not by itself determine the exact operative manoeuvres.

What is delayed anastomotic urethroplasty?

Through a perineal incision, the scarred segment is excised until healthy urethral mucosa is reached on both sides. The ends are then joined without tension. Progressive manoeuvres can shorten the route when the gap is long. Most cases can be repaired through the perineum; complex redo cases or associated bladder-neck/rectal problems may need additional approaches.

What are the major long-term issues?

• Recurrent posterior urethral stenosis.
• Erectile dysfunction related mainly to the pelvic injury.
• Urinary incontinence if the bladder neck or sphincter is damaged.
• Bladder stones or catheter problems during prolonged suprapubic drainage.
• False passages from repeated endoscopic attempts.

Why repeated “core-through” procedures are a problem

A completely obliterated PFUI should not be treated by repeatedly trying to cut from one side toward the other. This can create false passages toward the rectum or bladder and makes later reconstruction harder. Short non-obliterative recurrence after a previous successful repair is a different situation and may occasionally be treated endoscopically.

What determines the difficulty of delayed PFUI reconstruction

The apparent gap length is only one part of pelvic fracture urethral injury. Surgical difficulty also depends on displacement of the prostate, scar density, false passages from previous instrumentation, bladder-neck competence and whether the urethral ends can be mobilised into a tension-free alignment.

Most delayed repairs are performed through the perineum. Progressive manoeuvres – greater urethral mobilisation, corporal separation, inferior pubectomy or rerouting in selected cases – are used only when simpler exposure does not provide a tension-free anastomosis. The operation is therefore tailored to the actual scar gap rather than chosen from the X-ray alone.

Erectile dysfunction after PFUI: trauma and surgery must be separated

Erectile dysfunction is common after severe pelvic fracture because the original trauma can injure nerves and blood vessels before urethral reconstruction is ever performed. Baseline erectile function should therefore be documented before delayed urethroplasty whenever possible.

The purpose of reconstruction is to restore a stable urinary channel while preserving continence and sexual function as far as the injury allows. Persistent erectile problems after recovery can be evaluated separately; they should not automatically be attributed to the urethroplasty itself.

What to bring for consultation

• Trauma CT and pelvic-fracture records.
• RGU + MCU/VCUG images.
• Any antegrade/retrograde cystoscopy findings.
• Dates and details of suprapubic catheter changes.
• Records of early realignment or previous endoscopic procedures.
• Baseline and current erectile function and continence.

The usual timeline after pelvic fracture urethral injury

Pelvic fracture urethral injury is often only one part of a major trauma admission. In the emergency phase, survival, haemorrhage control and associated abdominal/orthopaedic injuries come first. Bladder drainage is then established, frequently by a suprapubic catheter when urethral disruption is suspected or a catheter cannot be placed safely.

Some centres attempt early endoscopic realignment in selected stable patients. Realignment can shorten the later scar in some cases, but it does not guarantee that a stricture will be avoided. If obstruction develops, repeated endoscopic procedures should not delay definitive reconstruction indefinitely.

For delayed urethroplasty, the surgeon generally waits until the pelvic injury has stabilised, inflammation has settled and the patient can tolerate positioning and reconstruction. RGU plus MCU/VCUG are used to define the mature distraction defect. A suprapubic tract can also permit antegrade cystoscopy to assess the bladder neck, stones and proximal urethra. This staged timeline explains why “nothing is being done to the urethra” for a period after trauma: allowing anatomy to mature can make the eventual reconstruction more accurate and safer.

If the first treatment does not prevent a stricture

Whether the urethra was managed initially by suprapubic diversion alone or by early realignment, later narrowing is possible. A man who begins to void after realignment can still develop progressive stenosis, so follow-up of stream and residual urine matters.

A short non-obliterative narrowing after realignment may occasionally be treated endoscopically, but repeated urethrotomy for a dense distraction scar can create false passages and delay definitive repair. Once a mature obstructing defect is established, delayed anastomotic urethroplasty is generally the durable reconstructive option.

Associated pelvic injuries may influence timing: the patient must be able to tolerate lithotomy positioning and the fracture/fixation must be stable enough for perineal surgery. The reconstructive timeline is coordinated with orthopaedic and trauma recovery rather than decided from the urethra in isolation.

The reconstructive objective after pelvic fracture

The aim of delayed repair is to restore a dependable urethral channel while preserving the continence mechanism and avoiding repeated endoscopic procedures through dense pelvic fibrosis. The repair is usually approached through the perineum; the scar is excised and the healthy bulbar urethra is mobilised toward the prostatic apex.

If simple mobilisation does not provide a tension-free join, progressive manoeuvres can create additional reach. The exact sequence depends on the defect and the surgeon’s experience. These are reconstructive decisions made during exposure, which is why the measured gap on a preoperative image does not perfectly predict operative difficulty.

After healing, urinary flow and continence are reassessed separately. A patent anastomosis can coexist with stress incontinence or erectile dysfunction related to the original injury, and those problems may need their own treatment.
