尿动力学概论

Р尿动力学是泌尿外科学的一个分支学科,它主要依据流体力学和电生理学的基本原理和方法,检测尿路各部压力、流率及生物电活动,从而了解尿路排送尿液的功能和机制,以及排尿障碍性疾病的病理生理学变化。Р概要Р解剖与病理生理?发展概况?尿流率测定?充盈性膀胱压力测定?压力流率同步检查(排尿期膀胱测压)?尿道压力图测定?肌电图检查?影像尿动力学检查?盆底肌电刺激Р泌尿系统解剖РNeural control of the lower urinary tractРPelvic parasympathetic nerves (盆副交感神经)?arise at the sacral level of the spinal cord, excite the bladder, and relax the urethra. ? --- voiding (排尿)?Lumbar sympathetic nerves (腰交感神经)?inhibit the bladder body and excite the bladder base and urethra. ?--- continence (控尿)?Pudendal nerves (阴部神经)?excite the external urethral sphincter. ?---continence (控尿)Р下尿路神经支配Р储尿期反射Р排尿期反射Р膀胱的功能Р1?储尿器官?排尿的“泵”?弹性和粘弹性Р膀胱出口Р组成: 膀胱颈? 前列腺(男性)? 外括约肌? 盆底肌?功能: 尿控?
