The function of the ureter is to transport urine from the renal pelvis toward the bladder and to protect the renal parenchyma from distally generated backflow and back pressure. The ureter manifests peristaltic activity and can adapt its mechanical characteristics to diuresis amount. The changes in ureteral function resulting from obstruction are dependent on the degree and duration of obstruction. Even the rate of urine flow, the mechanical and anatomic properties of the ureter, the nature of disease process and the age of the patient influence the response of the ureter to obstruction. It is the purpose of this report to correlate the anatomic and physiologic properties of the ureter with normal and pathologic clinical situations.
输尿管的功能是将尿液从肾盂输送至膀胱，并保护肾实质免受远端产生的反流和反压影响。输尿管呈现蠕动活动，并且能够根据尿量调整其机械特性。梗阻导致的输尿管功能变化取决于梗阻的程度和持续时间。甚至尿流速率、输尿管的机械和解剖特性、疾病进程的性质以及患者年龄都会影响输尿管对梗阻的反应。本报告的目的是将输尿管的解剖和生理特性与正常和病理临床情况相关联。
