Functional scan..: Renal scan is usually ordered to evaluate arterial flow to the kidneys as well as cortical concentration and excretion of tracer. Lasix (furosemide) renal scan is used to rule out obstruction. Dmsa renal scan can be used to evaluate for pyelonephritis / scarring. ...Read more

What is it like to have a renal scan?

What is it like to have a renal scan?

Very reasonable test: The patient is positioned on table with nuclear camera usually positioned underneath. Via a vein the radiotracer usually Technetium 99m MAG3 is injected in a bolus while continuous imaging is being performed of the kidneys and bladder Sometimes lasix (furosemide) a diuretic is injected following the first phase of study to see if kidney might be obstructed. It generally is very easy low radiation test. ...Read more

Renal scan vs ivp. Why and how do they differ?

Renal scan vs ivp. Why and how do they differ?

Nuclear & US scans: Intravenous pyelogram gives much better anatomic detail than either us or nuclear scan, now mostly replaced by ct & ultrasound. Mag3 nuclear scan best to quantitate obstruction & relative function. Dmsa nuclear scan best to demonstrate kidney scars & areas of diminished or absent function. Ultrasound scan uses no radiation, good for screening for hydronephrosis, kidney cysts, tumors & stones. ...Read more

What does a renal scan with lasik mean?

I'm not sure: Did you mean retinal scan? Or renal scan with Lasix (furosemide) (the water pill)? If this is about eye surgery, then it is possible that you were told to have your retina checked prior to having lasser vision correction. Otherwise, you may have been set up for evaluatio of your kidneys. ...Read more

Recently found out that kidney enlarged due to hydronephrosis size of 18.8cm x 9.1cm x 10.4cm then renal scan no function is there a way to recover?

Recently found out that kidney enlarged due to hydronephrosis size of 18.8cm x 9.1cm x 10.4cm  then renal scan no function is there a way to recover?

Hydronephrosis: A kidney that is completely obstructed may show porr to no function on renal scan. The kidney should be drained with a stent or nephrostomy tube and the renal scan repeated after 4 weeks with the drain in place. If there is still ni function, then removal may be indicated. Discuss this with your urologist as soon as possible. ...Read more

Help! I have pain during renal scan with Lasix (furosemide) wash?

Help! I have pain during renal scan with Lasix (furosemide) wash?

Possible obstruction: I do not know findings of renal scan. Some people develop pain with diuresis from lasix (furosemide) because of sudden distension of collecting system. This may mean there is obstruction to collecting system or ueter and the sudden increased volume not handled well. Sometimes this occurs in obstructed kidneys following beer ingestion, another diuretic. Pain a lot of times when supine at night. ...Read more

Lab variability.: It's hard to put these numbers into context as you've added variance between labs. You'd need to have a few values drawn at the same lab to see what consistency (or not) your numbers have. The variability across labs makes these values difficult to reliably interpret. ...Read more

Having sharp pains under left rib, went for renal scan showed nothing but my CRP level is sitting at 43. Doctor doesn't know what it could be?

Having sharp pains under left rib, went for renal scan showed nothing but my CRP level is sitting at 43. Doctor doesn't know what it could be?

Need more info: This is not a site in which to attempt to establish a diagnosis, but would suggest that if you have had two abdominal surgeries in less than one year that your doctor should be looking assiduously for an intra-abdominal source of the pain, and a renal scan covers only the kidney. You might want to discuss this with them and if not satisfied consider getting a second opinion. Best wishes. ...Read more

I recently had a renal scan and after urinating an getting back on the table i couldn't see the left one only the right why? I have a stent already

Complicated Answer: Renal scans help determine blood flow, function and excretion from the kidneys. When there is not a kidney seen at the end of the study it could mean it was never seen(bad) or that it has completely emptied (good). With a stent i assume there was blockage. A renal scan is confusing to look at, since the left sided kidney is the left kidney. Your doctor will explain your findings in detail. ...Read more

38 year old female, I have had urinary reflux on left side all my life. Recent CT revealed Hydro in left kidney. Renal scan was normal, and follow up MRI showed a "pocket" in my left ureter. What should the next step be?

38 year old female, I have had urinary reflux on left side all my life.  Recent CT revealed Hydro in left kidney. Renal scan was normal, and follow up MRI showed a "pocket" in my left ureter.  What should the next step be?

Talk to Urologist: Talk to a Urologist. He/she may recommend uroflow studies to see if the reflux from the pocket is causing the hydronephrosis. They can also suggest treatments (surgery) to fix the problem, if necessary. But surgery is not without risk, which the Urologist should explain to you. Alternatively, talk to your primary or use HealthTap Prime to get referred to a knowledgeable physician. Good Luck! ...Read more

What can a kidney scan show?

Function, scars, obs: Renal scans can be very helpful to give differential kidney function. They can give us information about renal scars from previous infections and help us differentiate if a kidney is obstructed or not. The degree of obstruction can be determined with a scan. There are different nuclear scan isotopes and history of the problem will dictate which one is needed to answer the questi hope this help. ...Read more

What does a kidney scan usually involve?

What does a kidney scan usually involve?

Nuclear vs us: A nuclear medicine scan of kidneys involves intravenous injection of isotope that is extracted from blood stream by kidneys either for determination of function, scarring, or obstruction of kidneys.Different isotopes such as Tc99m MAG3 for excretion and Tc99m DMSA for scarring are used.Kidneys for anatomic imaging can utilize renal ultrasound. Nuclear medicine is for function. ...Read more

How much is involved during a kidney scan?

How much is involved during a kidney scan?

See below: If you mean a ct [computorised tomography] scan of the kidney, it may involve giving a dye intravenously which may be required for outlining structures within the kidney.It can also be done without the dye. The dye may cause disturbances to your kidney function which in most cases is reversible.Your doctor and radiologist determine if the dye is required. You may have to fast before the test. ...Read more
