健康个体的正常下尿路功能由三级神经中枢控制和调节,包括高级中枢(大脑)、次级中枢(脑桥)和初级中枢(骶髓)。由骶髓内的初级排尿中枢以及由骶髓发出的骶神经根和盆神经及阴部神经构成的神经通路,也称为骶神经反射弧,是下尿路功能最基本的控制和调节系统,其在排尿功能中的重要性越来越受到重视~([1-3])。在骶神经反射弧中,骶神经根囊肿引起的膀胱尿道功能障碍在文献中虽有报道,但还远未得到应有的重视~([4-10])。我们在近年来的临床实践中积累的病例
Normal lower urinary tract function in healthy individuals is controlled and regulated by the tertiary nervous center, including the superior central (brain), secondary (pons) and primary (sacral) nucleus. The primary urinary tract from the sacral canal and the sacral nerve roots and pelvic nerve and genitals nerve issued by the sacral sac constitute the neural pathway, also known as the sacral nerve reflex arc, is the most basic urinary tract function control and regulation system, which The importance of urinary function in the more and more attention ~ ([1-3]). In the sacral reflex arc, sacral nerve root cysts caused by bladder and urinary tract dysfunction in the literature although reported, but far from being given due attention ~ ([4-10]). The cases we have accumulated in clinical practice in recent years
