Bladder training for urinary tract symptoms in PD: A randomized controlled trial
Abstract
OBJECTIVE
To assess the feasibility and efficacy of bladder training for troublesome lower urinary tract symptoms (LUTS) in Parkinson disease (PD).
METHODS
In this single-center, single-blinded, randomized controlled trial, participants with a history of PD and LUTS were randomized to a 12-week bladder training program (BT) or conservative advice (CA). Outcome measures included a 3-day volume frequency diary, International Consultation on Incontinence Questionnaire (ICIQ)-Overactive Bladder Module, and ICIQ-Quality of Life Module. Co-primary endpoints were (1) patient perception of change and (2) change in number of urgency episodes at 12 weeks. Secondary endpoints included change in ICIQ scores, number of micturitions, and volume voided.
RESULTS
Thirty-eight participants were randomized (18 to CA, 20 to BT). Both CA and BT were associated with significant improvements in volume voided, number of micturitions, symptom severity scores, and measures of quality of life (all p < 0.05). At 12 weeks, compared to CA, BT was associated with significant superiority on patient perception of improvement (p = 0.001), significantly greater reductions in number of voids in 24 hours (mean decrease 2.3 ± 0.8 voids vs 0.3 ± 0.5 [p < 0.05]), and greater reductions in interference with daily life (2.1 ± 0.8 point improvement vs 0.3 ± 0.7 point deterioration [p < 0.05]). BT was not associated with change in urgency episodes (mean change 2.4 ± 1.5 urgency episodes vs 3.5 ± 1.5 [p NS]). At 20…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
