A urethral stricture is a scar formation, which impedes the anterior urethra lumen. A urethral stricture is either Congenital Acquired Everything that damages the Harnröhrenepithel or the corpus spongiosum can cause acquired stricture. Common causes include trauma sexually transmitted diseases such as gonorrhea unknown causes (idiopathic strictures) trauma, the most common cause, injuries caused by spreading or occasionally an iatrogenic injury (z. B. after traumatic catheterization or endoscopy) may be caused. Less common causes include lichen sclerosis urethritis (usually chronic or untreated) symptoms and discomfort, it may be that the symptoms only develop when the urethral lumen is decreased significantly. Strictures can cause a double stream of urine, obstructive voiding symptoms (eg. B. weak urinary stream, urinary retention, incomplete emptying), or recurrent urinary tract infections (including prostatitis). A urethral diverticulum may develop, sometimes by an abscess and, rarely, a fistula with extravasation of urine accompanied into the scrotum and perineum. Diagnosis Retrograde Urethrography or cystoscopy urethral stricture is suspected, as a rule, when the urethral catheterization is difficult. You should also be considered in men with gradual onset of obstructive symptoms or recurrent urinary tract infections into account, particularly if they have risk factors or are young. The diagnosis of urethral stricture is usually confirmed by retrograde Urethrography or cystoscopy. Therapy dilation or internal urethrotomy self-catheterisation Open urethroplasty The treatment is determined by the shape of the urethral stricture. Often, a dilation or endoscopy (internal urethrotomy) is performed. However, a dilation and endoscopy should be avoided in certain forms of strictures (z. B. complex strictures, such as very long-lasting or recurrent strictures or strictures that persist despite initial treatment). A daily self-catheterization may be indicated. It may be indicated an open urethroplasty if the stricture is localized and causes recurrent problems.
