Question 1

can a septated kidney cyst somehow become non-septated and no longer complex? could the u/s be showing something that looks like separation but isn't?

Accepted Answer

These are common: The kidney is a bunch of tubes. They can get blocked, injured, plugged and can deform. The kidney can scar, can grow back some parts somewhat (and have injuries, scars, stones, infections, etc.). So..deformities are common and they change over time. BUT kidney cancer grows and is solid and irregular. 
U/S are grainy and can't get the same angle. Picture changes/thing changes/kidney changes.

Question 2

what does multiple septated cyst on kidney mean?

Accepted Answer

Multiple walls: Complex cysts, vs. Simple cysts, share common walls with other cysts, have solid components in the walls, or calcifications.

A multiseptated cyst has multiple walls inside.

The radiologist will opine if features look suspicious and either recommend a repeat ultrasound in 6 months, or a ct to further clarify.

Question 3

how soon does a kidney cyst develop?

Accepted Answer

Anytime: Kidney cyst can already be present at birth, develop in childhood or as an adult. A simple kidney cyst is very common, in fact present in up to 1 in every 3 humans ; usually require no treatment unless they become symptomatic.

Question 4

what are the symptoms of a kidney cyst?

Accepted Answer

None: Usually no symptoms at all. Incidental finding in ultrasound. When they are very large may feel some discomfort in the flank area.

Question 5

will a complex kidney cyst go away on its own?

Accepted Answer

Surveillance: Complex kidney cyst should be followed by serial ultrasounds.Most of the cysts remain unchanged, however  some may either increase or decrease in size. Complex cysts must be followed by serial imaging.

Question 6

can a kidney cyst with septations ever disappear / dissolve?

Accepted Answer

No,...: Oftentimes, your described cyst with septations is an incidental finding and causes no discomfort and risk to you. Such cyst will stay with you forever and grow over time with its wide variation of evolution. If necessary, timely periodic renal US or CT may be required to see if there is a high suspicion for neoplasm, As to how to handle such, ask your radiologist or urologist for timely detail.

Question 7

can a very large (6.5) *benign* right side kidney cyst- later cause pain or any symptoms for concern?

Accepted Answer

Renal cyst : What wa stage cyst size, was in mm or cms. Either way a small cyst. Most of these don't cause issue.

Question 8

left kidney cyst 22mm?

Accepted Answer

Likely benign: While likely benign it is best to consult with your doctor to make sure it is not part of a more complex mass and to establish follow up imaging and referral to urologist if necessary.

Question 9

is a "low density lesion" a simple kidney cyst?

Accepted Answer

: No. The radiology report should include more detail and a diagnosis.

Question 10

can a simple kidney cyst change to a complex malignant cyst?

Accepted Answer

No.: Simple cysts are common and at your age 1 or 2 found in your kidneys are not worrisome. A simple cyst is not cancerous but if injury to that cyst leads to small bleeding within it, it can look "complex", meaning it is not easily distinguished from something more concerning such as cancer.  These cysts warrant closer monitoring.  Hope this helps!
