Abstract:
The female urethra is probably the most neglected organ in women. Female urethral stricture and primary bladder neck obstruction are rare clinical entities. Traditional and new surgical techniques have been described for the treatment of female urethral stricture. However, they are based on limited data. There is no consensus on best management. The techniques of urethroplasty all have a higher mean success rate (80-94%) than urethral dilatation (< 50%), albeit with shorter mean follow-up. Urethroplasty performed by experienced surgeons appears to be a feasible option in women who have failed urethral dilatation, although there is a lack of high-level evidence to recommend one technique over another.Primary bladder neck obstruction (PBNO) is a condition in which the bladder neck fails to open adequately during voiding. This leads to increased striated sphincter activity or obstruction of urinary flow without another anatomic cause being present, for example an obstruction caused by genitourinary prolapse in women. Watchful waiting, pharmacotherapy and surgical intervention are possible treatments.

Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
Urethra
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male...
