Abstract
Aims
The aim of this study was to evaluate whether ambulatory urodynamic monitoring (AUM) may reflect patient perception of bladder condition and treatment benefit in patients with overactive bladder (OAB).
Methods
A total of 33 women and 7 men 23 to 72 years old who were undergoing AUM were included in this study. At baseline, patients were asked to complete the following information in the micturition chart for 3 consecutive days. Patients were given anticholinergics once daily for the 2 weeks. Two weeks after the treatment, all patients received an identical repeat study.
Results
Most parameters of AUM, micturition chart and patient perception were improved 2 weeks after treatment. However, when Spearman correlation coefficients were performed, all AUM parameters did not correlate with patient perception of bladder condition after treatment although some AUM parameters regarding incontinence were associated with patient perception of bladder condition at baseline. In addition, when patients were divided as the βno or some benefitβ group (nβ=β25) and the βmuch benefitβ group (nβ=β15), all AUM parameters except total voided volume (Pβ=β0.004) were not significantly different in the two groups.
Conclusions
Because patients with pelvic floor dysfunction have widely varying expectations from treatment, the patient's goal for treatment is highly subjective. Our findings suggest that AUM does not take into account the patient perception of disease severity, and correlations between the patient view of treatment outcome and objective measures are poor. Therefore, strategies for assessing OAB should incorporate selfβperceived disease condition. Neurourol. Urodynam. 26:789β793, 2007. Β© 2007 WileyβLiss, Inc.
