What is aberrant renal?
Aberrant renal arteries are common in fused kidneys.

Can you live with a horseshoe kidney?

What problems can a pelvic kidney cause?

What is a dromedary hump in kidney?
Dromedary hump is a prominent focal bulge on the lateral border of the left kidney caused by splenic impression, which can mimic renal neoplasm. It is a benign anatomic variant and exhibits the same imaging characteristics as adjacent renal cortex with normal blood flow pattern on Doppler sonography.
Is Lobulated kidney bad?
Persistent fetal lobulation of kidney is a rare anatomic variant and can pose pitfalls in diagnostic imaging. It can mimic a renal neoplasm and sometimes even diagnosed on subsequent surgery and histology as a wrong radiological diagnosis.
Is Lobulated kidney normal?
Persistent fetal lobulation is a normal variant seen occasionally in adult kidneys. It occurs when there is incomplete fusion of the developing renal lobules. Embryologically, the kidneys originate as distinct lobules that fuse as they develop and grow.
What is ureteric kink?
Kinking arises as a consequence of the ureter adjusting length when the kidney descends. Kinking is seen at the area where the ureter is relatively mobile, that is, where it runs in the perirenal space. The boundary of the perirenal portion of the ureter can be determined approximately by finding the level of the CP.
What are polar arteries?
Inferior renal polar arteries are usually single and arise from the aorta (95.5% of cases), or the renal artery (1.4% of cases). They have also been reported arising from a suprarenal, common iliac, or superior mesenteric artery. … An inferior renal polar artery may give rise to a gonadal artery.

Can kidneys repair themselves?
It was thought that kidney cells didn’t reproduce much once the organ was fully formed, but new research shows that the kidneys are regenerating and repairing themselves throughout life. Contrary to long-held beliefs, a new study shows that kidneys have the capacity to regenerate themselves.
Why do kidneys fail?
Kidneys can become damaged from a physical injury or a disease like diabetes, high blood pressure, or other disorders. High blood pressure and diabetes are the two most common causes of kidney failure. Kidney failure does not happen overnight. It is the end result of a gradual loss of kidney function.
