We present a patient with left-sided obstructed megaureter secondary to neuropathic bladder. He was referred for technetium-99m dimercaptosuccinic acid ((99m)Tc-DMSA) renal cortical scintigraphy to evaluate renal cortical function. Images obtained 4 hr after injection showed significant activity in the dilated left ureter. When the ureter is visualized on DMSA scan, obstructive megaureter shoul...

There are different scoring systems available for determining the grade of breast cancer malignancy. Breast cancer tumors have been described for grades 1-3 using the modified Nottingham-Bloom-Richardson grading system. Determining the grade is very important for the clinicians to choose the best treatment options. Technetium-99m methoxy isobutyl isonitrile ((99m)Tc-MIBI) and pentavalent (99m)T...

OBJECTIVE To determine total lead body burden by the Lead mobilization test (LMT) by measuring 4 hours urinary lead excretion in the lead exposed as compared to unexposed industrial workers after administration of 10 mg/Kg of dimercaptosuccinic acid and correlate it with blood lead levels, at Wah district Rawalpindi. METHODS Total 149 males consisting of 87 lead exposed workers and 62 control...

BACKGROUND The degree of inflammatory reaction and leucocyte trafficking during acute pyelonephritis has been related to the risk of developing renal parenchymal scarring. Adhesion molecules play a central role in leucocyte recruitment during inflammation. AIMS (1) To determine whether circulating and urinary concentrations of E-selectin and intercellular adhesion molecule 1 (ICAM-1) were abn...

The spontaneous and chelator mediated excretion of mercury in urine was investigated in male subjects occupationally exposed to mercury vapour (alkaline battery and chloralkali plants) who did not exhibit any sign of kidney damage. The time course of the spontaneous elimination of mercury in urine was examined in seven workers (age 22-40) who had been removed from exposure to mercury vapour (av...

UNLABELLED Balancing image quality with radiation dose is a goal with every diagnostic procedure requiring radiation. Our institution compared the dosing of (99m)Tc-labeled succimer, commonly referred to as dimercaptosuccinic acid ((99m)Tc-DMSA), to pediatric patients using 2 methods of calculation, body surface area (BSA, the method we used from 2009 to 2010) and body weight (BW, the method we...

INTRODUCTION. Urinary tract infection is the most common serious bacterial infection in children. The aim of this study was to compare the value of different laboratory and imaging techniques in detecting renal involvement in acute pyelonephritis. MATERIALS AND METHODS. In a cross-sectional study of patients 1 month to 14 years of age diagnosed with urinary tract infection were examined with sy...

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 ...
