交感神经和副交感神经参与下尿路的自律神经调节对正常排尿是不可缺少的。正常排尿机能障碍时,不管是神经原性还是非神经原性均可造成尿失禁或产生梗阻性排尿困难。尿失禁的类型有遗尿症,多见于中高龄妇女的紧张性尿失禁、尿急和前列腺术后的尿失禁。造成排尿困难的原因多为尿道通过障碍的尿道阻力增大,此外,逼尿肌无力,收缩不充分,产生排尿困难,或者两个原因同时存在。关于正常膀胱机能的机制以往有两种理论:一是立足于解剖学的机械论基础,认为副交感神经起排尿的主要作用;二是认为膀 Sympathetic and parasympathetic involvement of the lower urinary tract autonomic regulation is essential for normal urination. Normal voiding dysfunction, whether neurogenic or non-neurogenic can cause urinary incontinence or obstruction dysuria. Types of urinary incontinence enuresis, more common in women of advanced tension incontinence, urinary urgency and urinary incontinence after prostate surgery. Difficult to urinate due to urinary tract obstruction due to increased urethral resistance, in addition, detrusor weakness, inadequate contraction, resulting in dysuria, or both exist. The mechanism of normal bladder function in the past, there are two theories: First, based on the mechanical basis of anatomy, that the parasympathetic main role in micturition; the second is that the bladder
