[Pharmacologic treatment of urinary dysfunctions].

After reviewing the nervous control of the lower urinary tract, the author defines the action of various drugs on the bladder, bladder neck, urethra (smooth and striated sphincter). The drugs are classified according to their stimulant or blocking effect on the sympathetic and parasympathetic nervous systems and alpha and betadrenergic receptors. Drugs acting on smooth and striated muscle fibres are then studied and the iatrogenic adverse effects of these drugs are mentioned.
