TY  - JOUR
AB  - Bladder neck descent (BND) has been implicated in the pathophysiology of stress incontinence and prolapse. The aim of this study was to evaluate a novel 2D technique for the evaluation of BND, the Urethral Descent Assessment Technique (UDAT). UDAT involves measuring BND during dynamic manoeuvres in live 2D ultrasound, by using the geometrical properties of parallel lines. The internal urethral meatus and distal end of the urethra are used as reference points. Y1 is the urethral height at rest (also the urethral length when the urethra is straight). Y2 is the urethral height on Valsalva. Y1 and Y2 are parallel lines. Y1–Y2 = BND. A horizontal line (X) connecting Y1 and Y2 is the forward movement of the bladder neck.Y1 mean 30.4 mm (95% CI ± 1.36 mm). Y2 mean 24.2 mm (95% CI ± 2.58 mm). X mean 12.1 mm (95% CI ± 1.66 mm). BND mean 6.2 mm (95% CI ± 1.47 mm). Bland–Altman plots and linear regression showed that UDAT is repeatable and reliable.
