Urethral Stricture (1)

What is the most common site for urethral stricture in men?

• Penile urethra

• Bulbar urethra

• Membranous urethra

• Prostatic urethra

• Fossa navicularis

The gold standard for evaluation of urethral stricture is:

• MRI pelvis

• Retrograde urethrogram

• Flexible cystoscopy

• Voiding cystourethrogram

• Uroflowmetry

The most common etiology of anterior urethral stricture worldwide is:

• Lichen sclerosus

• Trauma

• Iatrogenic

• Infection

• Idiopathic

A contraindication for visual internal urethrotomy (VIU) is:

• Bulbar stricture <1.5 cm

• Penile stricture 2 cm

• Membranous stricture

• Stricture with dense spongiofibrosis

• Single short bulbar stricture

Which instrument is used for optical internal urethrotomy?

• Sachse urethrotome

• Otis urethrotome

• Collin's knife

• Amplatz dilator

• Lithoclast

Optimal treatment for long segment (>2cm) penile urethral stricture is:

• DVIU

• Urethral dilation

• Anastomotic urethroplasty

• Buccal mucosal graft urethroplasty

• Perineal urethrostomy

The success rate of DVIU for short bulbar strictures is approximately:

• 95%

• 80%

• 65%

• 50%

• <30%

Which of the following is true regarding anastomotic urethroplasty?

• Best for penile strictures

• Can be used for all strictures >3 cm

• Is tension-free

• Avoids excision of spongiofibrosis

• Requires graft always

Best imaging modality to evaluate posterior urethral disruption after pelvic trauma:

• Cystoscopy

• CT urogram

• VCUG

• RUG + VCUG

• MRI

Which statement is true about urethral stents in stricture disease?

• Widely used in anterior urethra

• Have high long-term patency

• Ideal for traumatic strictures

• Not recommended routinely

• Used in pediatric patients
