Accurate diagnosis of detrusor areflexia using combined uroflowmetry and abdominal wall electromyography.

Twenty-three patients who previously demonstrated no detrusor contraction during cystometry were evaluated using a combined uroflowmetry and abdominal wall electromyography. Ten patients voided without abdominal straining (normal detrusor reflexia), 11 could not void without abdominal straining (detrusor areflexia, detrusor weakness, or bladder outlet obstruction), and 2 had equivocal findings with the method.
