What is the predictive value of urodynamics to reproduce clinical findings of urinary frequency, urge urinary incontinence, and/or stress urinary incontinence?

INTRODUCTION AND HYPOTHESIS

The aim of this study was to determine the predictive value of urodynamics to reproduce clinical findings of urinary frequency (UF), urge urinary incontinence (UUI), and/or stress urinary incontinence (SUI).

METHODS

We retrospectively reviewed the data of patients diagnosed with UF, UUI, and/or SUI and subsequently underwent urodynamics. Urodynamic findings were correlated with clinical findings to determine the predictive value of urodynamics.

RESULTS

A total of 537 patients (366 females and 171 males) met study criteria. Two hundred seventy-eight patients had symptoms of UUI; 59% demonstrated detrusor overactivity on urodynamics. Three hundred eight patients had SUI on history and physical examination; 45% had urodynamic stress incontinence. A low maximum cystometric capacity (<200 ml) was not significantly associated with urinary frequency (p = 0.4).

CONCLUSIONS

Urodynamics has a low predictive value to reproduce clinical findings of UF, UUI, and/or SUI. Many patients with evidence of UF, UUI, and/or SUI on history and/or physical examination do not demonstrate supporting urodynamic evidence.
