DMSA scintigraphy is an imaging technique that relies on the detection of small amounts of radiation after injection of radioactive material. Because the dose of radioactive material is small, the risk of causing damage to cells is low. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed. Radioactive material is injected into a vein in the person’s arm and travels through the body to the kidneys. Special cameras and computers are used to create images of the radioactive material as it passes through the kidneys. The radioactive material makes the parts of the kidney that are infected or scarred stand out on the image. DMSA scintigraphy is used to show the severity of kidney infection or kidney damage, such as scarring. | DMSA scintigraphy is an imaging technique that relies on the detection of small amounts of radiation after injection of radioactive material.

Other Diagnostic Studies
Voiding cystourethrogram (VCUG)
A VCUG is an x-ray image of the bladder and urethra taken while the bladder is full and during urination, also called voiding. The procedure is performed in an outpatient center or hospital by an x-ray technician supervised by a radiologist, who then interprets the images. Anesthesia is not needed, but sedation may be used for some people. The bladder and urethra are filled with contrast medium to make the structures clearly visible on the x-ray images. The x-ray machine captures images of the contrast medium while the bladder is full and when the person urinates. This test can show abnormalities of the inside of the urethra and bladder and is usually used to detect VUR in children.
Dimercaptosuccinic acid (DMSA) scintigraphy
DMSA scintigraphy is an imaging technique that relies on the detection of small amounts of radiation after injection of radioactive material. Because the dose of radioactive material is small, the risk of causing damage to cells is low. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed. Radioactive material is injected into a vein in the person’s arm and travels through the body to the kidneys. Special cameras and computers are used to create images of the radioactive material as it passes through the kidneys. The radioactive material makes the parts of the kidney that are infected or scarred stand out on the image. DMSA scintigraphy is used to show the severity of kidney infection or kidney damage, such as scarring.
Histopathological Exam
Xanthoranulomatous Pyelonephritis is usually confused with a malignancy and surgery is performed. The histopathological examination of the resected specimen confirms xanthogranulomatous pyelonephritis which is not a very common phenomenon.[1]
