To assess whether a change in clinical diagnosis and management following ambulatory urodynamic studies result in symptomatic improvement of patients.

84 consecutive patients having ambulatory urodynamic assessment between 1st January 2015 and 31st December 2015 were reviewed. 38 patients were excluded where follow-up data were not available. The urinary symptoms before and at a minimum of 6 months following ambulatory urodynamics were assessed in 46 patients of median age 53.0 years. Both storage and voiding symptoms were assessed (as listed in the table).  Statistical analysis was performed by Mann Whitney U Test for Non-Parametric Data. P<0.05 was considered statistically significant.

Change in primary urodynamic diagnosis occurred in 30 (67%), change in clinical diagnosis in 29 (64%) and change in management in 28 (62%) patients. This resulted in significant improvement in urinary symptoms of: day frequency; night frequency; urgency; urge urinary incontinence; stress urinary incontinence; urinary incontinence of unknown cause; poor flow; and strain void (Table).

Ambulatory urodynamic assessment correctly identified the true cause of an individual's urinary symptoms. This led to a significant improvement in urinary symptoms six months after changing management and treating the true urodynamic cause of the urinary dysfunction.

The urodynamic and clinical diagnosis was changed in a two-thirds of patients following ambulatory urodynamics and resulted in significant improvement in urinary symptoms.
