Strictures of the female urethra are narrowings of the intima of the canal of a greater or less degree, which impede or prevent the passage of the urine by the natural course from the bladder. They are congenital or acquired, single or multiple, and may be classified as stenosis or obstructive, atresia or retentive, atresia, non-retentive, when the urethra becomes occluded from disuse associated with vesicovaginal fistula and atresia with urine discharged through the umbilicus via a patulous urachus. Various modifications of these varieties are found associated with malformation of the bladder.
Congenital atresiae are usually located at the neck of the bladder, or in the upper third of the urethra, but obliteration of the entire canal, or its absence, has been noted. Acquired cases, if traumatic, are situated at or near the site of the injury, while, if non-traumatic, they are found usually in the middle third of the
