Urological Outcome of Posterior Urethroplasty in Patients in Assuit University
The management of posterior urethral disruption secondary to blunt pelvic injury remains
 controversial. While many groups have recommended early realignment of urethral distraction
 injuries, Classic reports advocate a suprapubic cystostomy at the time of injury with
 delayed, perineal approach urethral re- construction 4 to 6 months after injury . Timing of
 the intervention typically is classified as :

 1. -Immediate treatment: when it takes place less than 48 hours after injury,

 2. -Delayed primary treatment : after 2 to 14 days, and

 3. -Deferred treatment : 3 months or more after injury.
It is important to make a distinction between posterior urethral stricture and a pelvic
 fracture urethral distraction defect. Urethral stricture indicate a narrowing of the urethral
 continuity due to either instrumentation or partial urethral tears. In urethral distraction
 defects there is a gap between the membranous urethra and the bulbar urethral end. A
 distraction injury also involve all or any portion of the membranous urethra.

 Immediate open repair of posterior urethral injuries is usually associated with a higher
 incidence of strictures, re-stenosis, incontinence and impotence. Difficulty in identifying
 structures and planes as a result of hematoma formation and edema also hamper adequate
 mobilization and subsequent surgical apposition.

 Contemporary urethral realignment employs actual realignment by fluoroscopic and endoscopic
 guidance of flexible cystoscopes that keep the urethral ends in the same cephalocaudad axis,
 followed by Seldinger technique catheter placement. The urethral catheter, which is usually
 maintained for 4 to 6 weeks, acts as a guide that allows the distracted urethral ends to come
 together as the pelvic hematoma slowly resorbs.

 In the unstable or multisystem trauma patient, realignment often is delayed a few days to
 weeks (typically 2 to 14 days). the patient is managed by damage control and resuscitated in
 the intensive care unit while the urine is diverted by suprapubic tube placement first. Once
 the patient is stable, delayed urethral realignment is performed. Endourologic and radiologic
 techniques for realignment, theoretically, should not affect potency or urinary continence
 because no manipulation occurs of the periprostatic tissues or neurovascular bundles.

 Types of surgical repair employed in posterior urethral distraction defect are 1) anastomotic
 urethroplasty, 2) Buccal mucosal urethroplasty, 3)Scrotal or penile island and 4) Johansen's
 urethroplasty. We aim to compare the outcomes of different management approachs for patients
 with posterior urethral distraction injuries after pelvic fractures in Assiut University
 Hospitals.

 Aim of the work To evaluate outcomes of posterior urethroplasty in patients with pelvic
 fractures and posterior urethral distraction defect according to different patient
 characteristics (Age, prior manipulation), type of injury (type of fracture, gap length) and
 time of intervention.
The inclusion criteria are:

 All patients with pelvic fracture and urethral distraction injury (PFUDDI) except patients
 with any of the exclusion criteria.

 The exclusion criteria are:

 1. Bladder neck injury

 2. Rectal injury

 3. Urethrorectal injury

 4. Spinal cord injury

 5. Associated anterior urethral strictures
