Why DTPA scan is done?

A renal DTPA scan is a nuclear medicine exam in which a small amount of radioactive material (radioisotope) is used to measure the function of the kidneys, to see how the left and right kidney work comparatively. This test allows any sites of blockage to be identified and detected.

What is captopril used for in nuclear medicine?

Use in Nuclear Medicine Captopril is used in conjunction with renal imaging (renogram) for the detection and characterization of the hemodynamic significance of renal artery stenosis in renovascular hypertension (1,2).

What is the difference between DMSA and DTPA scan?

A DMSA scan is usually static imaging, while other radiotracers like DTPA and MAG3 are usually used for dynamic imaging to assess renal excretion.

When do you need a DTPA scan?

Renal DTPA scan is a process for diagnosis and evaluation of kidney functioning. It involves intravenous administration of radiopharmaceutical material to assess the drainage pattern of kidneys and to find out if any area is not functioning properly.

What are ACE inhibitors examples?

Angiotensin-converting enzyme inhibitor (ACE inhibitors) drugs include Benazepril (Lotensin), Captopril (Capoten), Enalapril/Enalaprilat (Vasotec oral and injectable), Fosinopril (Monopril), Lisinopril (Zestril and Prinivil), Moexipril (Univasc), Perindopril (Aceon), Quinapril (Accupril), Ramipril (Altace), and …

What are diuretics drugs used for?

Diuretics, also called water pills, are a common treatment for high blood pressure. Find out how they work and when you might need them. Diuretics, sometimes called water pills, help rid your body of salt (sodium) and water. Most of these medicines help your kidneys release more sodium into your urine.

Why are ACE inhibitors contraindicated in renal artery stenosis?

Abstract. Angiotensin-converting enzyme inhibitors (ACEIs) are contraindicated in patients with bilateral renal artery stenosis due to risk of azotemia resulting from preferential efferent arteriolar vasodilation in the renal glomerulus due to inhibition of angiotensin II.

Do ACE inhibitors cause renal artery stenosis?

ACE inhibitors were developed in the 1970s and have revolutionised the management of renal and cardiac diseases. Unfortunately, as with most drugs, there are side-effects and contra-indications (including significant aortic and renal artery stenosis).

When should you suspect renovascular hypertension?

Suspect a renovascular cause if diastolic hypertension develops abruptly in a patient < 30 or > 50; if new or previously stable hypertension rapidly worsens within 6 months; or if hypertension is initially very severe, associated with worsening renal function, or highly refractory to drug treatment.

What is captopril Renography?

A captopril renal scan is used to evaluate for the presence of renal artery stenosis and renovascular hypertension. This captopril scan is performed in order to rule out renal artery stenosis in patients with high blood pressure.

How do you prepare for a renal scan?

scan because of the medicines used in each one. Both tests also can compare the amount of kidney function in the right and left kidneys. Preparing for the Scan Before coming to the hospital, read the explanation that follows and explain to your child what will happen during the test. For young children, use simple words and explain only shortly before the test. Children 4 years and under may require sedation for their procedure. You will be given certain

Does captopril cause hyperkalemia?

Hyperkalemia was seen in 30.6% of patients on irbesartan or losartan, 27.2% on captopril, 21.7% on fosinopril, 21.5% on lisinopril, and 16.5% on benazepril. One hundred seventy five patients were on combined ACEI and ARB.

What is a DTPA renal scan?

What is a DTPA scan? Renal DTPA scan is a process for diagnosis and evaluation of kidney functioning. It involves intravenous administration of radiopharmaceutical material to assess the drainage pattern of kidneys and to find out if any area is not functioning properly.

Can captopril cause orthostatic hypotension?

Postural, or orthostatic, hypotension is defined as a fall in blood pressure related to a change in position. Minoxidil and diltiazem dilate arterioles; therefore, they are not likely to cause postural hypotension. Prazosin, captopril, and losartan all reportedly can cause orthostatic hypotension.
