Horseshoe kidney with surplus renal vessels: A case report in Thai cadaver.

ABSTRACT

A horseshoe kidney (HK) was discovered in an 84-year-old Thai male cadaver during routine dissection. Inferior poles of the kidneys fused to form a parenchymatous isthmus and constituted a HK. The HK located anterior to the abdominal aorta and the inferior vena cava at a level lower than the normal kidney. Both renal hila directed anteriorly and ureters which drained from each pelvis descended anterior to the isthmus to enter the urinary bladder. Eight renal arteries and five renal veins were observed. In this case the bulky isthmus, anatomical abnormalities, and a variable blood supply were found in association with the HK. It is important to be aware of this anomalous existence in clinical practice, especially during kidney surgeries, kidney transplants, or surgical and endovascular procedures on the aorta.
