title: Detrusor activity at rest in patients with idiopathic detrusor hyperreflexia.
abstract: The detrusor activity of the bladder at rest was investigated in the supine position for one hour following instillation of 100 cc of saline in 8 patients with idiopathic hyperreflexia. During the investigation, 5 patients showed bladder hyperreflexia. In 4 cases the activity was accompanied by an increase in the anal sphincter activity, while 1 case showed decreasing sphincteric activity prior to contractions. An analysis of the distribution of the contractions revealed a predominant frequency. The frequency and the amplitude of the detrusor contractions were independent of the bladder volume. Low provocation prolonged cystometry might be a future method of studying bladder activity and bladder pharmacology.
