“…Test results below 20 cm H,O pressure in 3 patients with clinically severe neurogenic paralysis of 3, 6 and 10 years duration were ascribed to myogenic degeneration: one had 1000 ml residual urine while in the other two the capacity was of this order with a residual urine amounting to one-half. Also, as known from other studies (Kirwin & Hawes, 1934;Plum, 1960), a single overdistension may impair the myogenic properties, as was seen in one patient whose test result was previously almost constant but was lowzred (from 18 to 13 cm H,O pressure) when a test was performed 2 hours after a single spontaneous overdistension (1000 ml) had been relieved. When the history is suspect for previous, recent or chronic muscular damage, reservations should be taken in evaluation of the test result.…”

Neurogenic Bladder Diagnosed Pharmacologically on the Basis of Denervation Supersensitivity

A test described by Lapides et al. 1962 for diagnosis of neurogenic bladder, based on denervation supersenisitivity of detrusor to cholinergic stimulation, is critically reviewed. The "localized stretch response of bladder muscle" to instillation of fluid described by these authors seems to be an artifact. In a modified method developed by the author the denervation test consists of a continual reading of the intravesical pressure response to subcutaneous administration of 0.25 mg carbachol (equivalent to 2.5 mg bethanechol) after the bladder has previously been filled with 100 ml saline and allowed to accomodate. The maximum rise in pressure (cm H,O) following the chemical stimulation, above the basal pressure prior to this, constitutes the test result. By this technique 197 tests were performed in 64 patients.
