Which of the following is true about Horseshoe kidney?
High-Yield Explanation
The lower poles of the two kidneys (or sometimes the upper poles) may be fused. The connecting isthmus may lie either in front of, or behind, the aoa and inferior venacava. The ureters pass anterior to the isthmus. The inferior mesenteric aery also passes anterior to the isthmus which limits the ascent of the horseshoe kidney.
