Background: To present a simple clinical scoring system that can be utilized in selecting women with overactive bladder symptoms who would benefit from further urodynamic assessment.
Materials and Methods: This was a retrospective study done at a tertiary centre. Filed data of 210 women with OAB symptoms who presented at urinary incontinence clinic were analyzed. Women were grouped into those with detrusor overactivity (DO) and those without DO according to filling cystometry. The variables which were independently associated with DO were used to create a score that can be used for selecting women for further urodynamics assessment.
Results: Women with DO had significantly higher incidence of nocturia (92% vs 62%, p <0.001) urgency (86% vs 66%, p=0.002) and frequency (76% vs 51%, p=0.001). The detrusor overactivity score was calculated by adding the value of the corresponding symptom as follows: nocturia = 3, urgency = 2, frequency = 1. The sensitivity and specificity were 83% and 52% respectively at a cut-off value of 4. Women with a score ≥4 are expected to have DO when assessed by further urodynamic studies.
Conclusion: Detrusor overactivity score can be utilized for selecting women with OAB symptoms who would benefit from performing further urodynamic assessment.
