Die Harnröhrenenge und Blasenhalsstenose der Frau – Fakt oder Mythos – Was ist zu tun?

Abstract: Harnröhrenenge ▼ Anatomie der weiblichen HarnröhreDie Harnröhre der erwachsenen Frau hat eine Länge von 2,5-4 cm und kann an jeder Stelle stenosieren. Die Sphinkter-Aktivität wirkt auf der gesamten Länge, die Harnröhre besitzt 2 glatte Muskelschichten, eine äußere zirkuläre und eine innere longitudinale Schicht. Dieser glatte Muskel dünnt sich nach distal aus, speziell die äußere

Given the relative rarity of female urethral strictures with only small case series published, a statement regarding the superiority of one approach over the other is hardly possible.…”

“…It is a relatively uncommon reason of lower urinary tract symptoms (LUTS), causing storage symptoms (frequency, urgency, urge incontinence, nocturia) and voiding symptoms (decreased force of stream, hesitancy, incomplete emptying), although in this condition the variety of symptoms may be present simultaneously in several combinations. Although the true prevalence of PBNO is not clear and little is known about the etiology, previous urinary tract infections (UTIs), trauma, or prior surgeries of the urethra are suggested to play a role in the pathogenesis of the condition [2]. The diagnosis is based on urodynamic findings, characterized by relative high-pressure, low-flow voiding (cut points for the obstruction of 15 mL/s or less for maximum flow rate [Q max ] and greater than 20 cm H 2 O for detrusor pressure at maximum flow), as described by Nitti et al [3];, however, radiographic evidence of obstruction at the bladder neck with relaxation of the striated sphincter and no evidence of distal obstruction is also necessary [1].…”
