Urethral calibration or measurement of the urethral diameter may be useful in women with irritative voiding symptoms (urgency, frequency, dysuria and post-void fullness) who are being evaluated for urinary incontinence. Some of these women may be found to have voiding dysfunction, the urethral syndrome or sensory urge incontinence. These disorders in women are usually associated with functional rather than physical obstruction. Hole (1972) showed that the urethral caliber in women with the urethral syndrome was no different from that of controls. However, it is important to rule out true urethral stenosis as a cause of obstructive voiding or detrusor overactivity. Relative urethral stenosis associated with atrophic urethritis or the urethral syndrome is not uncommon. Women who have urethral stenosis and suffer from voiding dysfunction, urge incontinence or the urethral syndrome may benefit from dilatation.
