AIMS: To estimate the effect of plantar-flexion on the wave amplitude of involuntary detrusor contraction and the severity of urinary urgency during filling cystometry in patients with detrusor overactivity (DO).
METHODS: Twenty-two consecutive patients with DO were enrolled. During urodynamics, the mean peak detrusor pressures of each contraction were documented and compared. At the beginning of the 2nd or 3rd wave, patients were asked to perform continuous plantar-flexion by pushing their tiptoes against the floor. Following each wave, patients were asked to grade the severity of the urgency by a visual analogue scale (VAS).
RESULTS: The mean peak detrusor pressure without plantar-flexion was 58 cmH2O (95% CI: 46.3-69.7) compared to 31 cmH2O (95% CI: 23.1-38.9) with plantar-flexion (P < 0.001). All patients reported a reduced degree of urgency during plantar-flexion reflected in a significant reduction in mean VAS score from 9.3 (95% CI: 9-9.5) to 4.7 (95% CI: 3.9-5.4; P < 0.0001).
CONCLUSIONS: Self-performed plantar-flexion maneuver might reduce the severity of urinary urgency and the magnitude of overactive detrusor contractions, which may have a role in the conservative therapy of detrusor overactivity.
