It is classically described that there are three sites in the ureter where a kidney stone will commonly become stuck: where the ureter meets the renal pelvis; where the iliac blood vessels cross the ureters; and where the ureters enter the urinary bladder, [9] however a retrospective case study, which is a primary source, of where stones lodged ...
The vas deferens consists of an external adventitial sheath containing blood vessels and nerves, a muscular middle layer composed of three layers of smooth muscle (with a circular muscle layer interposed between two longitudinal muscle layers), and an internal mucosal lining consisting of pseudostratified columnar epithelium (which bears the ...
The external iliac vein is crossed by the ureter and internal iliac artery which both extend towards the middle. In males it is crossed by the vas deferens and in females the round ligament and ovarian vessels cross it. Psoas major lies to its side, except where the artery intervenes. [4] The external iliac vein may have one valve, but often ...
The ureters cross the pelvic brim near the bifurcation of the iliac arteries (which they run over). This "pelviureteric junction" is a common site for the impaction of kidney stones (the other being the uteterovesical valve). The ureters run posteriorly on the lateral walls of the pelvis.
Both common iliac arteries are accompanied along their course by the two common iliac veins, which lie posteriorly and to the right. Their terminal bifurcation is crossed anteriorly by the ureters. [1] This is significant, as the bifurcation of the common iliac artery is the second point of ureteric constriction. [1]
Vesical arteries are variable in number. They supply the bladder and terminal ureter. The two most prominent are the superior vesical artery and the inferior vesical artery. [1] The superior vesical artery comes off of the internal iliac artery and sometimes the umbilical artery. [2] The inferior vesical artery comes off of the internal iliac ...
The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. The vesicular branches of the internal iliac arteries supply the bladder. [1] It is a short, thick vessel, smaller than the external iliac artery, and about 3 to 4 cm in length.
Relation of arteries and veins to ureters, view from the back of a male (the ovarian veins substitute for the internal spermatic veins in females [1]) Ovarian vein syndrome is a rare (possibly not uncommon, certainly under-diagnosed) condition in which dilation of the ovarian vein compresses the ureter (the tube that brings the urine from the ...
