[Detrusor ischemia. linical effects].

Three basic theories of the development of an overactive bladder that have experimental and clinical evidences have been described, including neurogenic, myogenic, and urothelial. Based on the results of the literature analysis, the authors suggested the existence of detrusor ischemic disease as a result of compressive impairment of its blood flow due to incomplete or short-term relaxation under overactivity or hydraulic compression of the vessels by excessive urine volume in case of hypoactive bladder.
