What is diuretic renography?
Diuretic renography involves the administration of a loop diuretic (eg, 0.5 mg/kg of furosemide) prior to radionuclide renal scanning or during IVP, while the latter involves percutaneous insertion of a catheter into the dilated renal pelvis, followed by fluid perfusion into the pelvis at a rate of 10 mL/min.
How is a renogram performed?
A Nuclear Medicine Renogram is performed using a special radioactive material that, when injected into the blood stream shows the kidney blood supply and filtering action of the kidneys. Nuclear Medicine scans are performed using very small amounts of radioactive material.
What is a renogram used for?
A renogram is a nuclear medicine test of the kidneys. It can be used to see how well each kidney is working and whether urine passes on into the bladder without obstruction.
What is a DMSA scan?
What Is A DMSA Renal (Kidney) Scan? The DMSA renal scan is a nuclear medicine test that gives doctors detailed pictures of the kidneys. DMSA (dimercapto succinic acid) is a short-lived radioisotope that goes directly to the kidneys once inside the body and only stays radioactive for a few hours.
How is hydronephrosis treated in the kidneys?
Once hydronephrosis is detected through laboratory tests and imaging studies, immediate treatment must be provided to the patient to prevent or minimize damage to the kidney. Treatment usually consists of: Removing the excess urine from the kidney:This is typically done through a procedure known as a nephrostomy.
What is a renal scan / isotope renogram / renal scintigraphy?
What is Renal Scan / Isotope Renogram / Renal Scintigraphy? Renal Isotope Scan or an Isotope Renogram is a diagnostic procedure done by nuclear medicine specialists using a radioactive tracer to study the structure and function of the kidneys.
When to use a diuretic before a renogram?
Diuretic Renogram – Some patients may also receive diuretics like furosemide before the procedure. Diuretics are used in cases of hydronephrosis or dilatation of the upper urinary tract. They help determine if an obstruction is responsible for the pathology.
What kind of tests are done for hydronephrosis?
After a diagnosis of hydronephrosis is made, the doctor will perform urine and blood tests to see if an infection is present. Antibiotics—prescribed for up to seven days—are usually administered.
