Diet modification: You can have your urine analyzed for kidney stone risk factors. My usual recommendations are 1) increase plain water to at least 2 liters a day 2) decrease sodium intake 3) decrease animal protein intake 4) add a teaspoon of real lemon juice to diet daily. ...Read moreSee 1 more doctor answer
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
Yes frequently: Small stones can easily be missed, by any ultrasound machine especially by office ultrasound machines. Spiral ct scan is the most reliable imaging tool for small kidney stones. Flank pain & microscopic blood in urine are frequently good clues to presence of stones. Good news is that small kidney stones usually pass spontaneously & require no intervention. ...Read more
Yes: Ultrasound may not see the stone well but may see swelling in the tube (ureter) where a stone has clogged up the drain. A cat scan (ct) is usually the preferred test to better see the stones. But, unlike ultrasound exposes you to some radiation. ...Read more
Depends: For renal stones (in kidney), ultrasound is usually adequate. Can also see dilation of the kidney when stone is blocking the outflow tube (ureter). For better clear picture and to see ureteral stones which are closer to bladder, ct scan is better. However, all ctscans must be considered carefully given the radiation exposure to the patient which ultrasound does not have. ...Read more
My fiancee got a kidney stone of 6mm in size according to the ultrasound, is it possible to pass it without surgery?
Ureteral stone: The size of the stone does not correlate well to the intensity of the pain. The nearly unbearable pain of "ureteral colic" is from spasm of the muscular ureter. Although likely to pass on its own within a few days, a 3mm stone sometimes will get stuck and fail to progress. A 6mm stone, less likely usually after 5 days, i recommend having the stone extracted with a ureteroscope as an outpatient. ...Read moreSee 1 more doctor answer
I recently had an ultrasound of my right kidney where a kidney stone was found along with a 3mm bright echo was found. Should i be concerned?
Probably not...: Increased use of us or ct to evaluate body pain had led to finding small asymptomatic stone or mass in kidneys, lungs, liver, etc. Which is incidental and poses substantial dilemma on how to handle these subclinical findings. For kidney stone of 3 mm, i would leave it alone if you have no stone-related symptoms., but followed yearly with a x-ray film (kub). More detailing, work with urologist. ...Read more
Is it possible to have kidney stones, but not have any evidence of them in urine samples or ultrasounds?
Yes: These stones may be too small see on ultrasound and a routine urinalysis may easily miss stones as well. The best test for diagnosing the majority of stones in the urinary tract is a ct scan without contrast. This will detect the majority of kidney stones but a few may be missed occasionally. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Seriously- renal stones are the result of postive and negatively charged particles in urine binding together and precipitating as solids- most frequently as calcium- oxalate. This happens most often when the urine is concentrated- ie when you are dehydrated. And trying to pass these stones from the kidney to the bladder is incredibly painful. ...Read more
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
