What can be the reasons of cortical thinning and scarring in kidney? Can surgery be responsible for it?

Kidney stones: You had surgery for stones in your kidney. Sometimes the stone causes blockage of urine and this build up of waste products increases the pressure in kidney leading to scar and thining. The surgery attempts to clear up the blockage. ...Read more

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

Why the area of focal cortical thickens in midpolar region of left kidney. What can be the result & how can it be treated?

Why the area of focal cortical thickens in midpolar region of left kidney. What can be the result & how can it be treated?

Dromedary hump?: A common cause of focal kidney thickening of the left kidney is a normal anatomic variant called a dromedary hump. However, suspicious areas that might represent tumor or areas of infection often need a ct scan with contrast or ultrasound with intravenous contrast to make sure a more serious problem is not present. ...Read more

What are symptoms with kidney cortical thinning?

Not necessarily any: Kidney cortex contain nephrons or tiny filters ; is outer part of kidney. Can be result of hydronephrosis ; is swelling of entire kidney due to obstruction, congenital or acquired form stone or tumor. Symptoms can be flank or upper abdominal pain, blood in urine, also nausea ;/or vomiting.

Don't worry...: Largely, confirmed simple renal cyst on us requires no further follow-up, but in practice, repeating us every 2-3 yrs for 1-2 times to serve reassurance remains a common practice. Remember: despite medical advance, all care today is still based on indirect evidence resulting from continual collection and analysis of available, existing experience. So, what stated is just like that. More? Talk... ...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

How to treat or remove cortical cysts of kidneys?

How to treat or remove cortical cysts of kidneys?

May not be needed: Treatment of renal cysts often depends upon appearance on imaging studies, in particular CT scans. With a CT scan without and with contrast, one can tell if there are any parts of renal cystic lesions that enhance, or pick up dye and "light up". Other characteristics, such as calcium associated with cyst walls or septations can be suspicious. Round cysts are likely benign. Talk to a urologist. ...Read more

What is small sized kidneys with parenchymal desease and cortical cyst?

What is small sized kidneys with parenchymal desease and cortical cyst?

Nephrologist: Small sized kidneys means kidneys appear smaller on ultrasound images. This must be evaluated in relation to the body size, age and renal function. On kidney ultrasound, kidney appearance is usually compared to liver, if kidneys appears more enhanced, it usually represents parenchymal disease which may be due to many causes like diabetes, hypertension etc. You must discuss with nephrologist. ...Read more

What is small sized kidneys with parenchymal disease and cortical cysts?

What is small sized kidneys with parenchymal disease and cortical cysts?

Cystic Disease: Typically small sized kidneys can be congenital (born like that), or in many instances as your kidney function gets worse the kidney scars and get smaller- there are exceptions to this as diabetes kidney disease, HIV related kidney disease, infiltrative diseases (lymphoma) etc can be large. If you have small kidneys as well as cysts- this could be related to underlying disease- complicated answer. ...Read more

Cortical echo genicity is mildly increased in both kidney. Serum cretinine is 151.Is the kidney is damaging.?

Cortical echo genicity is mildly increased in both kidney. Serum cretinine is 151.Is the kidney is damaging.?

Some: Cortical echogenecity means you may have chronic kidney disease. However, what actually matters is serum creatinine if it is 1.51 mg/dl as I presume from your message "151", then your kidney function is about 60-70% if you are an average 70-80kg male, little worse for a woman with same info i.e. 50-60%. ...Read more

Ultrasound results showed Cortical Cysts on rt. Kidney. New development as I've had many tests on my kidneys. Is this a concern?

Cyst or cysts?: The answer depends on the number of cysts (mainly) as well as its / their size, location, characteristic (s), etc. Use HealthTap Prime to upload pictures of the kidney to get a better understanding. In general, a single "solitary" cyst isn't worrisome - anyone can get 1. However, if multiple develop, or if there is a family history of aneurysms & the like, then this could prompt concern & screening ...Read more

Cysts: Renal cysts are present in nearly 50% of the population over 50 y/o. They have a classification system that estimates the likelihood of them being benign called the bozniac classification. Size is less relevant than wall thickness or complexity of the cyst. ...Read more

Kidney ultrasound show increased cortical echogenicity (right >left) with mild loss of corticomedullary differantiation. Advice: kft correlation. Mean?

Correlate blood test: Increased cortical echogenicity with mild corticomedullary differentiation, usually means medical renal disease. Kft probably means kidney function tests. These are blood tests such as serum creatinine, bun, and GFR (glomerular filtration rate). ...Read more

My 5 years male child has 2 small scars on left kidney. Rt is not functional due to PUV at birth time. All tests are normal now. Pls advice for future?

Renal Scarring: Posterior Urethral Valves can cause congenital damage and destruction to the kidneys. Your child's condition was managed at birth by fulguration procedure. With one functioning kidney remaining (albeit scarred) and normal blood tests currently, your child should receive yearly routine physical exams with special attention to his kidney function, overall growth pattern, and sports participation. ...Read more

Does traditional kidney stone surgery leave a scar?

Does traditional kidney stone surgery leave a scar?

Possibly: If by "traditional", you mean the need to surgically cut out stones from the kidney, ureter, or bladder then yes. These operations are rare in the western world nowadays, but they can be done via minimally invasive methods to minimize scarring. However, nearly all stones can be managed with external lithotripsy (noninvasive), endoscopically (no scar) or percutaneously (small scar) these days. ...Read more

I have been told my daughter who is 9 has scars on her kidneys. What causes this? Related to her urine infections?

Variable causes: When urinary tract infections climb up to the kidney they can injure and scar the sensitive tissue. Once injured, these can scar and this will show up on a variety of kidney studies. There are also separate infectious, metabolic and genetic conditions that can produce kidney scaring. ...Read more

R-kidney 8.2 cms, l-k 9.0 cms, 7mm calculus at lower polar of r-k, moderate hydronephrosis and parenchymal scars l+r kidneys, ureters dilated. Serious?

R-kidney 8.2 cms, l-k 9.0 cms, 7mm calculus at lower polar of r-k, moderate hydronephrosis and parenchymal scars l+r kidneys, ureters dilated. Serious?

Serious...yes: The hydronephrosis part is what makes this serious. The stone is basically plugging the urine outlet and the kidney is suffering. You need to see a urologist and have lithotripsy to break up the stone. At 7 mm it is unlikely to pass on its own. Otherwise you may loose function in that kidney and since you already have some scarring, your kidney function reserve is dwindling. ...Read more
