“…If one observes a funnel-shaped widening of the trigonum ( = positive answer) within 10 minutes after the intravenous injection of 10 to 15 mg of phentolamine mesylate (alpha-blocking agent), one may assume that the alpha-receptors at the trigonal level are a direct contributing factor responsible for the chronic retention. Over the past 8 years we have observed that this category of patient generally responds well to long-term oral alpha-adrenolytic treatment with phenoxybenzamine hydro chloride (Krane & Olssen, 1973;Mobley, 1976;Stockamp & Schreiter, 1975).…”

Abstract. The efficacy of alpha-adrenolytic treatment with oral phenoxybenzamine chloride (40 mg per day during three to four months) has been assessed both clinically and urodynamically among 249 patients with neurogenic bladder function. The results were significantly better in patients with autonomous (n = 95) than in the ones with automatic (n = 154) bladders (urethral sphincter spasticity and detrusor sphincter dyssynergia dominating the clinical picture in the latter event). A further striking difference was noticed when the data were analysed with regard to the patient's age, a far better therapeutic response being regularly recorded in subjects below age 35, while minimal and inconsistent improvements were observed in the older age group. No major side effects were encountered.Caution is however required in tetraplegics where phenoxybenzamine may aggravate orthostatic hypotension. On the other side the drug proves highly beneficial in these same patients in that it markedly lowers the incidence of dysreflexic states.

“…Die Idee, den Blasenauslaßwiderstand bei neurogen bedingter Blasenentleerungsstörung mittels Gabe eines Alphablockers zu senken, ist keine neue (Amark and Nergardh, 1991;de 62 Voogt and van der Sluis, 1976;Seiferth, 1976;Stockamp and Schreiter, 1975) …”

“…Alpha adrenergic blocking agents have been shown to be useful in the treatment of lower motor neuron bladder (Stockamp & Schreiter, 1975). In patients with lower motor neuron bladder and flaccid pelvic floor muscles the membranous urethra does not usually present an obstacle to voiding.…”

Abstract. The diagnostic methods and treatments of neurogenic bladders are reviewed from the spinal shock period to the final stage of bladder function. Emphasis is placed upon intermittent catheterisation and urodynamic investigations with discussion on the respective value of some pharmacological agents and transurethral operations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
