Distal Urethral Stenosis in a Girl (Differential Diagnosis Voiding Disorder)
VCUG in a 7-year-old girl with recurrent urinary tract infection and voiding disorder. The urethra is dilated with a sudden change of the calibre at its distal end.
The diagnosis is stenosis of the urethral orifice in a girl. In general and specifically, urethral stenosis does not occur frequently in girls.
The cause is an increase in the collagenic connective tissue of the posterior urethral lip and a close connection to the anterior border of the hymen. The diagnosis may be
comfirmed by calibration with Hegar's dilators during cystoscopy; the dilators may also be used for bouginage of the stenosis.
