输尿管 Ureter

(重定向自Ureteropelvic junction)

输尿管拉丁语:Ureter)是位于腹膜外位的细长肌性管道,左右各一,约平第2腰椎上缘起自肾盂末端,终于膀胱。长约20~30厘米,平均管径0.5~1.0厘米,最窄处口径只有0.2~0.3厘米。输尿管的主要作用是将肾脏所排泄的尿液排入膀胱。

输尿管可分为上、中、下三段,也可称为腹段、盆段、膀胱段(壁内段)。输尿管的腹段始于肾盂下端,在腹后壁腹膜的深面,经腰大肌前面下行至其中点附近,与睾丸血管(男性)或卵巢血管交叉,通常血管在其前方走行,达小骨盆入口处。在此处,左输尿管越过左髂总动脉末端前方;右输尿管则经过右髂外动脉起始部的前方。

Ureter 输尿管

(重定向自Ureteropelvic junction)

In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. In the adult, the ureters are usually 25–30 cm (10–12 in) long and ~3–4 mm in diameter. Histologically, the ureter contains transitional epithelium and an additional smooth muscle layer in the more distal one-third to assist with peristalsis.
