Overview
Other diagnostic studies for pyelonephritis include voiding cystourethrogram, dimercaptosuccinic acid scintigraphy, and histopathological exam.
Other Diagnostic Studies
Dimercaptosuccinic acid (DMSA) scintigraphy
DMSA scintigraphy is based on the identification of radiation in minute quantities after injecting a radioactive material. Since the radioactive material is used in a minute quantity, there is less risk of cell damage. It can be performed in an outpatient or inpatient setting by qualified personnel. This investigation can be carried out in the absence of anesthesia. Radioactive substance injected an arm vein reaches the kidneys. Attached cameras create images of the path taken by the radioactive substance. The effected parts of the kidney become prominent. DMSA scintigraphy shows the extent of kidney involvement. Cortical Scintigraphy is preferred for the diagnosis of acute pyelonephritis in children.[1][2][3]
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. Microscopic examination after performing biopsy shows the inflammatory mass composed of lipid-laden macrophages and chronic inflammatory cells.[4]
