Introduction:Diethylenetriaminepentaacetic acid (DTPA) is a chelating agent used as a radiopharmaceutical compound, 99mTc-DTPA, for renography. Doxorubicin (DOX) on the other hand is an effective chemotherapy drug used to treat a variety of solid malignancies.  Both 99mTc-DTPA and DOX may be used in close succession in patients undergoing DOX based chemoth...

urinary tract infection (uti) may lead to irreversible changes in renal parenchyma. early diagnosis using scintigraphy with technetium-99 m -labeled dimercaptosuccinic acid (dmsa) scan and early treatment may decrease or prevent development of renal parenchymal lesions. the aim of this study was to assess the occurrence of renal parenchymal lesion in children admitted with a first-time symptoma...

Biocompatible gold nanoparticles (AuNPs) are particularly interesting for photo-thermal therapy (PTT) of cancer treatment because their ability to convert light into heating efficiently. Nevertheless, the random accumulation AuNPs in tissues, mainly determined by retention time bloodstream, is one main limiting factors use PTT applications. For this reason, efficient targeting and monitoring se...

Giant renal calculus is rarely seen in urologic practice. A 69-year-old woman who had right giant renal calculus with poorly functioning opposite kidney is presented. She was with a history of right pyelolithotomy for large renal calculus 10 years back. Ultrasonography(USG), uncontrast computed tomography ( CT ), plain abdominal X-ray ( KUB ) and intraveneous urography ( IVU ) revealed a giant ...

99m The use of Tc-DTPA is for brain imaging renal flow study, and glomerular filtration rate measurement. Following intravenous injection, 99mTc-DTPA is rapidly cleared from the blood by glomerular filtration. Renal retention is 7% of the injected dose at 1 h and 95% is excreted within 24 h. It is neither secreted nor reabsorbed by the tubules and has negligible biliary excretion and eliminatio...

Objective: Congenital hydronephrosis is a common prenatally diagnosed anomaly associated with an incidence of approximately 0.5-1% in newborns. The purpose of this study was to clarify the value of 99 m diethylenetriamine pentaacetic acid (99mTc-DTPA) in the assessment of renal function impairment of pediatric hydronephrosis. Methods: A total of 48 children with unilateral ureteropelvic junctio...

abstract background: screening for patients at risk of renal scarring is a challenge in children with acute pyelonephritis (apn). diuretic tc-99m mercaptoacetyltriglycine (mag3) scintigraphy with zero time injection of furosemide (mag3-f0) was observed to display focal parenchymal disorders. the advantages of mag3 include: lower radiation dose and short duration of the test. the aim of this stu...

urinary tract infection (uti) is a common disease in childhood specially in female. in this study 50 patients with stablished diagnosis of uti were evaluated by both renal scan with tc-99m dmsa and renal sonography. the study revealed that most urinary tract infections are in children, female sex between 5-9 years of age. therefore the most important complications (renal scarring) are also comm...

BACKGROUND AND PURPOSE Diethylenetriamine penta acetic acid (99mTc-DTPA), a substance which indicates glomerular filtration, is distributed equally in blood and tissue after a bolus intravenously injection. Ambulatory Renal Monitor (ARM) is a portable and non invasive device which monitors extracorporeally the clearance of intravenously injected 99mTc-DTPA. We examined correlation between half-...
