Kidney (Definition)

The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more

I have a cyst on my right kidney that has increased in size. Would that cause my back to hurt and be nauseous? Also is it normal to have a lesion on

Here are some...: Cyst (s) in kidneys may happen to some 50% of people after age > 50. Most are benign - simple cyst, and may slowly grow in size. These cysts would not cause pain or nausea, but their related rare sudden internal bleeding or infection may induce pain with nausea. How to handle sickness?

Is a kidney lesion something to worry about?

Is a kidney lesion something to worry about?

Depends.: Some lesions are benign, some malignant, and many unknown until treatment or a biopsy is performed. Many tumors, cysts, or kidney stones that are benign do not need treatment, and may be observed. Some benign lesions can enlarge in size to later cause problems, and require treatment though they are not cancerous. And malignant lesions should be treated by an experienced urologist. ...Read more

I Was Diagnosed with a hyodense lesion on my right kidney. Is This Serious?

Lesion right kidney: This finding requires further characterization. If this was an ultrasound finding, then the choice is to do no further testing, vs repeat ultrasound in 4-6 months, vs undergo MRI with Gadolinium. This may be a simple cyst. Harmless. It may be a complex cyst, which is uncertain until further characterized by MRI. ...Read more

What does "kidney lesion most likely cyst but cannot definitively say since scan was unenhanced" mean?

What does "kidney lesion most likely cyst but cannot definitively say since scan was unenhanced" mean?

No contrast: A ct scan can be done with IV contrast, oral contrast, both or no contrast. The contrast that goes through the blood stream causes certain areas of our body to enhance while other solid areas may not. Differentiating between a solid tumor or mass from a benign cyst or a malignant appearing cystic tumor can be clarified by what areas enhance with contrast and which do not. Your study had none. ...Read more

What test are needed for a kidney lesion to make sure it isn't cancer.

What test are needed for a kidney lesion to make sure it isn't cancer.

Depends: A radiologist may be able to certify it as benign based on images (benign cysts are extremely common), or may do some dye studies. You have a right to find out from your physician what's the appropriate workup for your mass, and whether biopsy or some other means of getting tissue is in order. ...Read more

"Incidental low attenuation lesion" found in kidney. 7mm in size. What does "low attenuation" mean?

"Incidental low attenuation lesion" found in kidney. 7mm in size. What does "low attenuation" mean?

Low attenuation: Means it absorbs less xrays. Usually this means that it is something less dense than adjacent tissue. For example, a fluid filled structure (such as a cyst) has lower attenuation than a solid mass. In the kidney, an incidental low attenuation lesion usually indicates a benign cyst. This can be confirmed with an ultrasound. ...Read more

Was told I have a cyst, or a lesion on my right kidney, I been having pains in that area, what should I do?

Kidney: A simple cyst on the kidney is of no concern. A lesion could be any abnormal finding, including a cyst. The important distinction would be if the radiologist called it a mass. Discuss details with your doctor. You can get some blood and urine tests as well. Further imaging like a ct scan can also evaluate for stones and ureteral problems. ...Read more

It depends: A Lesion in the kidney can be a benign cyst, which are common. But it can also be a solid lesion.

MRI shows 6mm lesion on kidney and reads "may demonstrate minimal partial internal septation"? What is the significance of the word "minimal? "

MRI shows 6mm lesion on kidney and reads "may demonstrate minimal partial internal septation"? What is the significance of the word "minimal? "

Radiology hedge.: Renal cysts range from simple to complex. Simple cysts are common and are of no concern whatsoever (Grade 1). Complex cysts have solid regions which are usually an indicator of cancer (Grade 5). By using the word "minimal septation" the radiologist is giving the cyst a Grade 2, which is more likely benign than not. Chances are very good that this is nothing to worry about. ...Read more

Here are some. ..: I wouldn't jump into the ship of overwhelming worry over this finding as described. Instead, make sure the finding is correlated with your clinical scenario over time to discern what could be the underlying cause if identifiable. On the other hand, the report may be a slight "normal" variation with no clinical significance at all. So, ask Doc for logical interpretation and follow-up before jumping ...Read more

6mm renal lesion: Hello~ you have a STABLE SMALL renal mass. Anything under 4cm is considered small, and the smaller the more chance of it being benign. The commonest mass is a cyst. They are benign. Yours is "septate" so its solid. Solid masses > chance of malignancy. You should see a Nephrologist to follow this. But its probably benign thanks ...Read more

Probably most common is so called multicystic kidney displasia, birth defect where part of, or entire kidney is made up of a bunch of cysts. Opposite kidney is usually normal and child will have a normal life. May have a simple cyst, may have a complex cyst which is usually benign. Can be an obstructed calyx or blocked part of duplex kidney. Ask dr. ...Read more

The doctor said that my baby had a cystic lesion on her kidney. What can be done? Is this serious?

Not necessarily: Cystic renal lesions range from simply cysts (spherical sac of fluid such as water) to more complex cystic masses such as cancer. If basic imaging was done and it isn't clear whether it is a simply cyst, it may be best to conduct further imaging such as a CT or MRI (with contrast). Hope this helps. Good luck! ...Read more

Need another scan for kidney then colonoscopy then surgery called da vinci surgery? I'm nervous says compex cystic lesion neoplasm cannot be excluded

CT scan findings: You are being evaluated, aka "worked up" for the cystic mass. Surgery has been recommended. Being anxious during this time is normal. Risk/benefit analysis of your case with your surgery team. Open, laprascopic and robotic are techniques, how your surgeon performs your surgery. Robotic is newer but not necessarily better. Talk to your regular doc, possible second opinion, be well. Pathology. ...Read more

See your doctor: That finding could be a kidney stone, complex cyst, scar tissue or a tumor. Evaluation with a CAT scan or MRI may be needed. Tumors and complex cysts can mean early cancers that can be cured by removing the kidney. However, most abnormal findings in the kidneys are not cancers. See your doctor for complete evaluation. ...Read more

Can there be a cyst and a exophytic solid mass lesion on a kidney? Are the thge same? Does the solid mass indicate cancer?

Need followup: Renal cysts are common. The majority are benign. Cysts can also be assoicated with malignancies and some malignancies have cystic areas. A solid exophytic mass may be more worrisome.
YOu need a further workup and you may need a biopsy or surrgical resection to know for sure. Discuss imaging and surgical options with your doctors. ...Read more

My lumbar MRI shows hyper intense lesion measuring 2.5 CM in right kidney probably related to a cyst. What should I do?

My lumbar MRI shows hyper intense lesion measuring 2.5 CM in right kidney probably related to a cyst. What should I do?

Seen answer: It’s not uncommon for one imaging examination to detect an “incidentaloma” – an unrelated observation in the obtained images. Talk to your dr. / radiologist – they may want to confirm this observation with a renal ultrasound or possibly a repeat MRI – if it is a renal cyst, these are common, and usually not of clinical consequence. ...Read more
