    Relationship of ureter and iliac artery

    Advertisements



    Can you tell me ureter crosses over common iliac artery or external iliac artery?
    Thank you!

    pic...

    hope that this helps....


    the ureter crosses over the common iliac artery... the common iliac artery divides into the external and iliac after the ureter crosses over it.. and then it travels towards the backside of the bladder which it appears to be traveling alongside of the internal iliac artery...

    But one Qbank question said the answer like this:file:///C:/Documents%20and%20Settings/aa/%D7%C0%C3%E6/USMLEstep1/ureter&iliacartery.gif
    That mean: Ureter crosses external iliac artery.

    I checked other sources... the ureter crosses at the end of the common Iliac artery or at the bifurcation where it crosses over the external iliac artery then goes to the backside of the bladder.... I'm assuming that either answer can be right... what do you think?

    Here is the link to one of the pages that I found the information... http://education.yahoo.com/reference...subject?id=254;

    I think ureter crosses over external iliac artery is correct one.

    that's a good picture.. but understand the path of the ureter,.. and follow it backwards from that picture, and it appears that it actually crosses at the bifurcation or near to it.... plus.. if it's not "concrete" USMLE won't post it as a question... if they do, they have to choose one or the other... but can't post both as answers... if they do, there will be challenges...

    In that Qbank question, choices are beginning of external iliac artery or internal iliac artery, and some other choices. In my mind, ureter crosses over common iliac artery (external iliac seems too far away for me), and HY Anatomy also said so, but I am wrong.

    in my opinion.. the answer choice should be the bifurcation of the common iliac artery OR external iliac artery, and once it crosses over, it then follows more medial pathway where it continues along with the internal iliac artery becoming narrow and traverses the bladder on the backside...

    My advice to you: don't fret about it.. if the question comes up on the actual exam, look at the answer choices and choose; It will be one of three choices as discussed here; If it does not, there are million more to choose from, and much more High yield...

    Good luck to you... )

    It definitely passes ant. to the very beginning of the ext. iliac a., NOT OVER THE COMMON ILIAC A. by any means,
    in other words it passed just after the bifurcation, so between these choices:
    a) external iliac a.
    b) common iliac a.
    b
    these are my references:
    1. Any valid Anatomy Atlas such as Sobota, Gray's
    2. Kaplan DVD, Anatomy: Abdomen & Pelvic
    wish u all luck....
