In my kidney ultrasound the result is normal size of kidneys with bilateral diffuse parenchymal disease,normal sonogram of the urinary bladder.

In my kidney ultrasound the result is normal size of kidneys with bilateral diffuse parenchymal disease,normal sonogram of the urinary bladder.

Not sure: what the question is, but there are numerous potential causes for abnormal appearing kidneys on ultrasound. Best to speak with your doctor about the results. The results have to be interpreted in the context of your entire clinical picture, the appearance on ultrasound is entirely nonspecific. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

What are the signs of a kidney stone on ultrasound?

What are the signs of a kidney stone on ultrasound?

Bright spots: Kidney stones show up on ultrasound as bright echogenic foci (white spots) within the substance of the kidney. If the stones are larger than 3 or 4 mm there will be a darker area behind the stone representing an acoustical shadow. Obstruction of the kidney by a stone will cause dilatation of the kidney's collecting system which will appear as black fluid spaces within the kidney. ...Read more

What is a punctate calculus in the lower pole of the kidney?

What is a punctate calculus in the lower pole of the kidney?

A tiny kidney stone: A punctate calculus refers to a very small kidney stone, generally 1-2 mm in size picked up on a CT scan as this is the most sensitive imaging study. A stone of this size should be passable if it decides to move down the ureter. I would recommend excellent fluid intake of 70-80 ounces daily and orange juice and lemonade daily. Your doctor should also monitor this stone periodically for growth. ...Read more

What does mild caliectasis of kidney mean? And stasis of urine in right proximal ureter?

What does mild caliectasis of kidney mean? And stasis of urine in right proximal ureter?

Dilatation: Caliectasis is a dilatation of the kidneys' urine collecting tubes within the kidney itself. It can reflect some degree of obstruction, infection, or reflux of urine from the bladder to the kidney. Stasis of urine in the upper ureter has a similar list or possible causes. ...Read more

What is the reason of formation kidney stone?

What is the reason of formation kidney stone?

Metabolic issue.: Kidney stones are initiated by metabolic derangements in the handling of urinary oxalate, uric acid or calcium, for example. These derangements can be hereditary, and they allow for crystals of these substances to form. These crystals serve as a nidus for stone creation. ...Read more

What is the cause of kidney stones?

What is the cause of kidney stones?

Many causes: In women the most common cause is not drinking enough water. In men, the most common is too much calcium in the urine and there are several causes for this. Find an expert in the metabolic evaluation of kidney stones, usually an endocrinologist, or go to a major medical center with a stone clinic. We can prevent over 90% of recurrences with proper evaluation and treatment of the underlying cause. ...Read more

Why stone is formed in the kidney?

Why stone is formed in the kidney?

Nephrolithiasis: There are many different types of stones including calcium oxalate (mono & dihydrate), calcium phosphate, struvite, cystine, indinvir, matrix and uric acid stones, to name a few. However, the types of stone is not the whole answer. A complete stone risk analysis also includes specific serum and urine studies. In general, stone for from concentrated urine leading to crystallization then to stones. ...Read more

I have creatinine serum of 1.64, bun 15 and bun to creatinine ratio of 9. An ultrasound of the kidneys revealed no stones or blockage. Is kidney damage confirmed?

I have creatinine serum of 1.64, bun 15 and bun to creatinine ratio of 9. An ultrasound of the kidneys revealed no stones or blockage. Is kidney damage confirmed?

Need more info: A 24 hr urine collection to calculate creatinine clearance would be most accurate in this situation. A level of 1.6 implies a possible decrease in kidney function, but creatinine alone is insufficient to determine absolute renal function. Age, sex, race and muscle mass can have an effect on creatinine. A nephrologist can monitor this and give guidance as to how to preserve remaining function. ...Read more

What are signs of a kidney stone being stuck in your kidney?

What are signs of a kidney stone being stuck in your kidney?

If stones grow to sufficient size they can cause obstruction of the ureter. Ureteral obstruction can cause pain, vomiting, blood in urine., the pain typically comes and goes in waves lasting 20 to 30 minutes. ...Read more

What is a questionable punctate calcific density in the kidney, CT report says that. Also what is a 1.2 CM probable cyst in the lower pole of kidney?

What is a questionable punctate calcific density in the kidney, CT report says that. Also what is a 1.2 CM probable cyst in the lower pole of kidney?

Kidney abnormalities: "calcific densities" in the kidneys usually represent calcifications or stones, depending on any other associated findings they may have mentioned. Sometimes kidney tumorsay calcify, but they would have mentioned any finding concerning for this. Cysts are very common, and if they meet certain well defined criteria (bozniak classification), they are usually benign and need no further follow up. ...Read more

Hi, My wife is in her 28th week of pregnancy and recent scan shows problem with the fetus kidneys. One of the kidney has multiple cysts and other kidney shows dilation. The reports says:

The fetal right kidney measures 52mm in length, shows dilation of p

Cystic kidneys: Sounds like either ARPKD ( Autosomal recessive polycystic kidney disease) or renal dysplasia due to obstructive uropathy. Both these conditions are compatible with life depending upon fetal lung maturity. Believe it or not-- you need normal kidneys for lungsto develop in utero. In any case my best advice to you would be to consult with a Pediatric Nephrologist, before the birth of the baby. ...Read more

Ct of abdomen- granular high attenuation material in both kidneys. Multiple stones in each kidney. Uniform attenuation in liver. What does this mean?

Ct of abdomen- granular high attenuation material in both kidneys. Multiple stones in each kidney. Uniform attenuation in liver. What does this mean?

Hard to be sure...: The description "granular high attenuation in kidneys" is not descriptive enough to know what the radiologist definitely meant. They should have put their interpretation of this finding in the impression. It may be related to the kidney stones they mention. Make sure you clarify with your doc. The phrase "uniform attenuation in the liver" is another way of saying nothing abnormal seen in liver. ...Read more

My scan result shows 3.4mm calyceal calculus in the middle calyx of right kidney...what to do doctor..

Nothing: Nonobstructing renal calculi are common. Nothing much to do unless you become symptomatic (pain, hematuria, infection) which could mean that the calcification is now likely causing an obstruction and needs removal, or lithotripsy ...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.
