OBJECTIVE The aim of this study was to compare the renal function measured with either 99mTc-DTPA or 99mTc-EC dynamic scintigraphies with that measured using 99mTc-DMSA static scintigraphy. METHODS the values of relative renal function measured in 111 renal dynamic scintigraphies performed either with 99mTc-DTPA (55 studies) or with 99mTc-EC (56 studies) were compared with the relative functi...

OBJECTIVES To examine the value of an intravenous urogram (i.v.U) in patients with abnormal differential (99m)Tc dimercaptosuccinic acid (DMSA) uptake without scarring or ultrasound abnormality. STUDY DESIGN Forty patients (age 0-19 years) were identified over a two year period in whom the differential renal uptake was >10%, who had smooth renal outlines, and had no evidence of scarring. All ...

BACKGROUND Controversy persists as to the need for both MIBG and bone scanning in routine evaluation of neuroblastoma. AIM To compare the efficacy of I-131- metaiodobenzylguanidine (MIBG) scan against that of conventional Tc99m- methylene diphosphonate (MDP) bone scan for the detection of skeletal deposition of neuroblastoma. METHODS AND MATERIAL The study included 57 patients (36 boys, 21 ...

UNLABELLED Capabilities of color and power Doppler sonography (DS) were prospectively evaluated for diagnosis of acute pyelonephritis and for prediction of scarring by comparison with 99mTc-dimercaptosuccinic acid scintigraphy (DMSA). METHODS Fifty-seven children (mean age, 5 +/- 3 y) with acute pyelonephritis were investigated by biologic testing, DS (DS 1), and DMSA (DMSA 1). Patients who w...

Vesicoureteral reflux (VUR) is one of the most important causes of urinary tract infection and renal failure in children. It is a potentially self-limited disease. The aim of this study was to evaluate the clinical course and significant factors in children with primary VUR. The medical charts of 125 infants and children (27.2 % males, 72.8% females) with all grades of primary VUR were retrospe...

Radionuclide Tc99m DTPA (Diethylenetriaminepenta Acetic Acid) renal imaging is being used to assist in the evaluation of overall GFR, the intra-renal transit time, the cortical transit time, response to frusimide injection, diagnosis of ATN and rejection in renal transplant cases. A study was conducted at PINSTECH in order to prepare DTPA kit locally and evaluate the labeling efficiency as well...

Crossed renal ectopia is a rare urinary system anomaly which mostly is asymptomatic and is diagnosed incidentally. Urinary obstruction, infection, and neoplasia of the urinary system and nephrolithiasis are main complications of this anomaly. A 6-year-old boy admitted to the hospital with colicky abdominal pain and nausea. Abdominal examination revealed tenderness in right lower quadrant. Urine...

 ABSTRACT COVID-19 mainly affects respiratory and immune systems, but other organs like renal, cardiovascular, lung and nervous systems could also be involved in both acute and chronic settings (1, 2). There is a lot of studies that demonstrate an increasing number of long COVID-19 who continue to experience persistent symptoms weeks or even months after the initial disease. Reports suggest...

Introduction Vesicoureteral reflux is a common disorder in children but can result in kidney scarring following acute pyelonephritis. The gold standard diagnostic to detect renal scars in children is 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy. DMSA has a number of limitations including radiation exposure, need for sedation, and radiotracer supply shortages. Contrast-enhanced ultrasound (...
