Disorders of micturition: neuropharmacologic basis and results of drug therapy.

The clinical use of various pharmacologic agents in problems of micturition is based on the new concepts of intrinsic urethrovesical innervation, presence and regional predominance of autonomic neuroreceptors, and experimental evidence of the effects of various drugs on the bladder and the urethra. A new concept, relating to the processes that control bladder filling and emptying, is coming into being and replacing the traditional concept based on anatomic grounds alone. On the basis of the published data, and from personal experience both experimental and clinical, pharmacologic agents singly or in combination can be effectively and safely used in various problems of micturition such as incontinence (enuresis, stress incontinence in women, postprostatectomy, urgency incontinence), and functional outflow obstruction caused by neurologic or non-neurologic disease processes.
