Cystometric variations during postural changes and functional electrical stimulation of the pelvic floor muscles

Postural changes did not affect the cystometric curves of bladder function that were hyperreflexic, flaccid or secondary to bladder wall changes (fibrosis and inflammation). However, postural changes did affect normal curves in some patients with a history of micsturition disorders and resulted in detrusor instability when the patient was standing or walking. Functional electrical stimulation of the pelvic floor muscles during the cystometrogram inhibited detrusor instability of these patients in all positions. Use of postural changes and functional electrical stimulation of the pelvic floor muscles during the cystometrogram inhibited detrusor instability of these patients in all positions. Use of postural changes and functional electrical stimulation of the pelvic floor muscles is suggested to determine actual bladder function and to exclude possible artifacts in the curve.
