Urethral strictures
Introduction
A narrowing of the urethra
Caused by injury or disease including UTIs
.and other forms of urethritis
Above insult leads to scar tissue formation
which contracts hence reducing the caliber
.of the urethral lumen
End result is the resistance to antegrade
. flow of urine and semen
Causes
• Traumatic
• Iatrogenic :post instrumentation( including
  catheter ,urethral endoscopy)
• Post operative :open prostatectomy
  ,amputation of the penis.
• Congenital
• Malignancies
Presentation :
• Obstructive voiding symptoms ,urine
  retention(decreased force of stream
  incomplete bladder emptying ,dribbling
  ,intermittency)
• UTI s
Complications •
• Retention of urine
• Urethral diverticulum
• Peri urethral abcess
• Urethral fistulas
• Urethral calculi
• Hernia ,heamorrhoides and rectal
  prolapse.
Management •
Principles of treatment
Proper understanding of the relevant
anatomy
Accurate diagnosis
Skilled surgical technique
Making diagnosis

Suggestive history
Findings on physical exam
Radiographic technique
:Radiographic imaging

Contrast studies achieved by retrograde and
.antegrade cystourethrography
Ultrasonography : A transducer placed
. longitudinally along the penis
 Can evaluate
 Stricture length
Degree and depth of spongiofibrosis
 Endoscopic evaluation
Done using either rigid or flexible
cystourethorgraphy
Treatment

Note : no medical therapy exists for urethral
 stricture
:Surgical therapy
 Uretharal dilatation
 Internal urethrotomy
 Permanent utrethral stents
 Open reconstruction
 Primary repair
Tissue transfer ,repair techniques
Urethral dilatation

 The objective in patients with isolated strictures
 Drawbacks
It‘s a blind procedure hence false passages can
 be created
 recurrence rate
infection
 Internal urethrotomy
Stricture is incised under direct vision using endoscopic
. equipment
Objective is to incise the stricture and ensuring
epithelialization before wound contraction reduces the
.lumen caliber
Complications

  Recurrence of stricture
  Bleeding
.Extravasation of the irrigation fluid into the perispongial tissues
[
  Permanent urethral stents
  Placed endoscopically
.Designated to be incorporated into the wall to produce a patent lumen
Most useful in short strictures located in the bulbar urethra and in elderly
.patients
  Draw backs
If placed distal to the bulbous urethra it can cause pain while sitting or during
.intercourse
  Migration of the stent
.Contraindicated in patients with dense strictures or prior urethral reconstruction
Open reconstruction

 Primary repair
Hold standard against which other procedures are
.compared to
Involves complete excision of the strictures with
 .reanstomosis
 Technical points to be observed
 Complete excision of the areas of fibrosis
 Widely patent
 Tension free anastomosis
Young patients have an additional benefit of having
compliant tissues hence wide strictures can be safely
.excised and primary anastomosis done
Complications
                                                    •
Post operative chordae
 Penile shortening
 Ejaculatory dysfunction
 Decreased glans sensitivity
The repair is usually stented with a silicon catheter
and urine delivered using a suprapubic catheter
.as healing takes place
Tissue transfer

Technique •
Reserved for patients in whom multiple
.procedures have failed
Conducted as two stage procedure
Success depends on the blood supply of the
.local tissues at the site of placement
Graft is harvested from desired non hair
bearing location e.g. Buccal mucosa
 .,rectal or bladder
1st stage

Urethra is opened via a ventral midline
incision and the scarred urethra is excised
.completely
Dartos fascia is mobilized bilaterally and
.closed over the urethral bed
Desired skin is harvested and sutured to
. the dartos covered ventral urethral bed
.Catheter is placed for suturing
2nd stage

Takes place 6-9 months after the initial
.operation
Skin strip is mobilized along the urethra
.that will be used to fashion a neo urethra
. Dartos fascia is not interfered with
.Must be water tight closure
 .Catheter is left in site for stenting purposes
: Complications

. Post voiding dribbling
.Post operative diverticulum
.Skin retraction of the ventral skin of the penis
.Urethra cutaneous fistula
Above can be minimized by having the appropriate
.experience and surgical technique
Oral complications : pain ,persistent numbness
.,tightness or coarseness over donor site
Contra indications to surgery

.Active urinary tract infection
Must rule out malignancy ,endoscopic
.biopsy done in case of luminal mass
Prognosis

• Prospective randomized comparison of internal
  urethrotomy and dilatation showed no significant
  difference in efficacy when used as the initial
  treatment.
• Recurrence rate is directly proportional to the
  stricture length.
• Rate at 12 months
• 2cm         ------ 40%
• 2-4cm       -----50% increased to 75% at 48
  months.
• > 4cm        ------80%
Stents

. Long term success rate of 84% at 5 years
.And increased patient satisfaction
Excision with primary anastomosis

. Most successful •
• Tissue transfer graft have overall success rate of > 95% over one year however there
    is deterioration over time
• External location and degree of scarring
• Benign or malignant prostate obstruction

urology.Urethral strictures.(dr.ismaeel)

  • 2. Introduction A narrowing of the urethra Caused by injury or disease including UTIs .and other forms of urethritis Above insult leads to scar tissue formation which contracts hence reducing the caliber .of the urethral lumen End result is the resistance to antegrade . flow of urine and semen
  • 3. Causes • Traumatic • Iatrogenic :post instrumentation( including catheter ,urethral endoscopy) • Post operative :open prostatectomy ,amputation of the penis. • Congenital • Malignancies
  • 4. Presentation : • Obstructive voiding symptoms ,urine retention(decreased force of stream incomplete bladder emptying ,dribbling ,intermittency) • UTI s
  • 5. Complications • • Retention of urine • Urethral diverticulum • Peri urethral abcess • Urethral fistulas • Urethral calculi • Hernia ,heamorrhoides and rectal prolapse.
  • 6. Management • Principles of treatment Proper understanding of the relevant anatomy Accurate diagnosis Skilled surgical technique
  • 7. Making diagnosis Suggestive history Findings on physical exam Radiographic technique
  • 8. :Radiographic imaging Contrast studies achieved by retrograde and .antegrade cystourethrography Ultrasonography : A transducer placed . longitudinally along the penis Can evaluate Stricture length Degree and depth of spongiofibrosis Endoscopic evaluation Done using either rigid or flexible cystourethorgraphy
  • 9. Treatment Note : no medical therapy exists for urethral stricture :Surgical therapy Uretharal dilatation Internal urethrotomy Permanent utrethral stents Open reconstruction Primary repair Tissue transfer ,repair techniques
  • 10. Urethral dilatation The objective in patients with isolated strictures Drawbacks It‘s a blind procedure hence false passages can be created recurrence rate infection Internal urethrotomy Stricture is incised under direct vision using endoscopic . equipment Objective is to incise the stricture and ensuring epithelialization before wound contraction reduces the .lumen caliber
  • 11. Complications Recurrence of stricture Bleeding .Extravasation of the irrigation fluid into the perispongial tissues [ Permanent urethral stents Placed endoscopically .Designated to be incorporated into the wall to produce a patent lumen Most useful in short strictures located in the bulbar urethra and in elderly .patients Draw backs If placed distal to the bulbous urethra it can cause pain while sitting or during .intercourse Migration of the stent .Contraindicated in patients with dense strictures or prior urethral reconstruction
  • 12. Open reconstruction Primary repair Hold standard against which other procedures are .compared to Involves complete excision of the strictures with .reanstomosis Technical points to be observed Complete excision of the areas of fibrosis Widely patent Tension free anastomosis Young patients have an additional benefit of having compliant tissues hence wide strictures can be safely .excised and primary anastomosis done
  • 13. Complications • Post operative chordae Penile shortening Ejaculatory dysfunction Decreased glans sensitivity The repair is usually stented with a silicon catheter and urine delivered using a suprapubic catheter .as healing takes place
  • 14. Tissue transfer Technique • Reserved for patients in whom multiple .procedures have failed Conducted as two stage procedure Success depends on the blood supply of the .local tissues at the site of placement Graft is harvested from desired non hair bearing location e.g. Buccal mucosa .,rectal or bladder
  • 15. 1st stage Urethra is opened via a ventral midline incision and the scarred urethra is excised .completely Dartos fascia is mobilized bilaterally and .closed over the urethral bed Desired skin is harvested and sutured to . the dartos covered ventral urethral bed .Catheter is placed for suturing
  • 16. 2nd stage Takes place 6-9 months after the initial .operation Skin strip is mobilized along the urethra .that will be used to fashion a neo urethra . Dartos fascia is not interfered with .Must be water tight closure .Catheter is left in site for stenting purposes
  • 17. : Complications . Post voiding dribbling .Post operative diverticulum .Skin retraction of the ventral skin of the penis .Urethra cutaneous fistula Above can be minimized by having the appropriate .experience and surgical technique Oral complications : pain ,persistent numbness .,tightness or coarseness over donor site
  • 18. Contra indications to surgery .Active urinary tract infection Must rule out malignancy ,endoscopic .biopsy done in case of luminal mass
  • 19. Prognosis • Prospective randomized comparison of internal urethrotomy and dilatation showed no significant difference in efficacy when used as the initial treatment. • Recurrence rate is directly proportional to the stricture length. • Rate at 12 months • 2cm ------ 40% • 2-4cm -----50% increased to 75% at 48 months. • > 4cm ------80%
  • 20. Stents . Long term success rate of 84% at 5 years .And increased patient satisfaction
  • 21. Excision with primary anastomosis . Most successful • • Tissue transfer graft have overall success rate of > 95% over one year however there is deterioration over time • External location and degree of scarring • Benign or malignant prostate obstruction • Post operative bladder neck contraction. • Complications • Chronic prostatitis • Chronic UTI • Epidydimal • Diverticula • Urethrocutaneous fistula • Peri urethral abscess. • Urethral carcinoma • Vesical stones from stasis • Ascending pyelonephritis. • Renal failure
  • 22. Circumcision .Is the surgical removal of some or all of the foreskin • • Indications : young boy • Social • Religion • Therapeutic: • Phimosis • Infection: balanitis ,balanoposthitis ,posthitis • Xeroderma balanitis obliterans • Paraphimosis tight phrenulum • UTI • Adults • Inability to retract foresking • Tight frenulum • Balanitis • Before radiotherapy
  • 23. Timing varies • • Technique • Plastibel • Open as in adult • Complications • Bleeding • Infection • Meatal ulcer • Meatal stenosis • Pain • Psychological trauma • Lose of glans sensitivity • An ulcerated meatus in the circumcised meatus is a frequent sumptom . • The ammonical diaper is the cause of this lesion. • Benefits
  • 24. Foreskin 50% at 1 year retractable 90% at 3 years 99% at 17 years Whitish ring of indurated skin.
  • 25. Phimosis • The foreskin can not be fully retracted over the glans penis . • Normal separation after 3 years • Non-retractability • Pathology :acquired • • .Balanitis xertica obliterans • Scarring • Balanitis • Repeated catheterization • Foreceful retraction • Untreated diabetic • Presentation • Pain during urination. • Obvious ballooning of foresking with urination.
  • 26. /RX • Betamethason 4-6 weeks Betamethason dipropionate 0.05% for 2 weeks Operation Circumcision
  • 27. Paraphimosis • The foreskin becomes trapped behind the glans penis and can not be reduced . • Treated as medical emergency if • -persists for several hours • -signs of lack of blood flow. • It can result in gangrene. • Caused by • -during penile exam • -penile cleaning • -urethral catheterization • -Cystoscopy
  • 28. :Treatment • Manual • Dorsal slit Circumcision •
  • 29. Ulceration of the urethral meatus • Is quite common in circumcised boys. • Delayed up to 2 years from circumcision. • Lack of protective prepuce • Friction • Ammonical dermatitis • Frenular artery ligation • Ulcer form a scab • Process cause fibrosis • Acquired pin hole meatus • follow up hypospedias repair . • phimosis • sparing or dribbling • chronic retention • renal impairment
  • 30. treatment • medical • local measures to soften the scab and alkalinization of urine . • Meatotomy
