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 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 ...
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 ...
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]
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 artery. [3] [4] The inferior vesical artery is a pelvic branch of the internal iliac artery in men; and in women it branches from the vaginal artery. [5]
The bladder receives blood by the vesical arteries and drained into a network of vesical veins. [11] The superior vesical artery supplies blood to the upper part of the bladder. The lower part of the bladder is supplied by the inferior vesical artery, both of which are branches of the internal iliac arteries. [11]
Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet.

Within the spermatic cord, the vas deferens is situated posterior (and parallel to) the vessels of the spermatic cord. [3]: 1297 The vas deferens traverses the inguinal canal to reach the pelvic cavity; it enters the pelvic cavity lateral to the inferior epigastric vessels. At the deep inguinal ring, the vas deferens diverges from the ...
