Kidney Horseshoe Kidney and the Mesenteric Artery!

Hi,

I was reading First Aid Embryology section and under the renal development i think pg.140 (FA 2012) it has stated that horseshoe kidney is stabilized or put in place by the inferior mesenteric artery but, in Dr.Goljan's audio lectures he has mentioned that it is the superior mesenteric artery that keeps the horseshoe kidney in place. The inferior mesenteric artery makes more sense though right? Could anyone please clarify this point?

Thank you so much.

I believe the textbook can be trusted more than his audios.
He has the correct explanation in RR on page.398, stating its the inferior mesenteric artery.

Thank you mizzy! I just made a note of it in the book and FA and highlighted it. That is surprising, maybe he meant to say the inferior but just blurted out superior?

There are a few mistakes in there, but regarding the horseshoe kidney, he actually said the right answer. ..
Are you listening to the day 4 lecture, 6th recording "hepatobiliary-pancreas",
thats where he started his kidney lecture from. I have the transcript which has his recording typed word to word, and this is what he said in the lecture:
"Horseshoe kidney-joined at the lower poles. Will ask what is restricting the movement of the kidney? IMA-it traps the kidney."--He actually said inferior. lol
..ermm..I guess follow along the transcript and RR textbook.

use common sense, if u know the embryology of kidney u can understand that development starts in pelvis and after that ascending of kidneys to their exxact position occurs. if lower poles of kidneys are united and during ascending of kidneys which artery is to come first on their way to stop ascending. obviously it'll be IMA.
