Value of selective reversible sacral nerve blockade in the diagnosis and treatment of the urge syndrome.

Interstitial cystitis, neurogenic disturbances of bladder emptying resulting from incomplete supranuclear lesions and idiopathic detrusor hyperreflexia are clinically always associated with frequency, nocturia, urgency or urgency incontinence (urge syndrome). These disturbances of bladder emptying are difficult to distinguish, even urodynamically. With selective sacral nerve blockade, it is possible to differentiate between forms urodynamically using a nerve-blocking anesthetic. Reversible selective sacral nerve blockade is also the treatment for idiopathic detrusor hyperreflexia.
