Most kidney cysts (fluid filled mass) are classified as “simple” and are very common. They are generally benign, and found incidentally during an ultrasound, CT or other scan performed for some other reason. Most often these simple cysts can be left alone with no worries. Rarely, a simple kidney cyst can enlarge enough to cause pain, and these can be treated by needle drainage or more permanently with surgery (usually laparoscopy with small incisions.) Some kidney cysts are classified as “complicated” and might have more worrisome or malignant features that warrant more comprehensive exams and treatments including surgery. Very rare are multi-cystic and poly-cystic kidneys that can in worst cases cause kidney failure requiring dialysis or kidney transplant.

What causes malrotated kidney?
Before birth, the kidneys normally pass through a complex series of developmental steps when they change position and orientation. Malrotated kidneys occur when these steps do not occur in the usual way so the kidney ends up in an abnormal position, orientation, or both. Malrotated kidneys are generally easily diagnosed by sonogram.
Often, kidney malrotation is found in an otherwise healthy infant or child, sometimes noticed on a prenatal (before birth) sonogram, and may not have any impact on health. In adults, kidney malrotation might be noticed when a person has body imaging for a completely different reason.
In some cases, a malrotated kidney can be associated with some functional problems in the way urine drains to the bladder and with vesicoureteral reflux (when some urine flows backwards through the urinary system). These problems may lead to urinary tract infections (UTI), which could be the only sign of the condition. More rarely, malrotated kidneys may be part of more complex combinations of congenital (birth) defects.
Additional testing or imaging might be recommended when a malrotated kidney is noticed in a baby, especially after a UTI.
What is ischemic nephropathy?
Johns Hopkins Medicine answered
Ischemic, which comes from the Greek word ischemia, means restriction of blood supply. Nephropathy is damage to the kidneys. Thus, ischemic nephropathy is dysfunction of the kidneys due to compromised blood flow in the arteries.
