OBJECTIVE In the literature, there are many reports comparing relative renal function calculated with Tc 99m DTPA and Tc 99m DMSA in adults and children. However, there is no consensus about the results. As there is indeterminacy in the reliability of Tc 99m DTPA for the calculation of the relative renal functions, we retrospectively designed a study to compare the relative renal functions meas...

INTRODUCTION Measurement of glomerular filtration rate (GFR) is critical for the diagnosis and stratification of chronic kidney disease (CKD). Recent studies have shown that cystatin C is superior to creatinine for the detection of impaired GFR, and several cystatin C-based equations for estimating GFR have been developed for this clinical application. We conducted the present study to assess t...

Nuclear medicine methods have important role in the evaluation of transplanted kidney. In this study 58 99mTc-DTPA scans were performed in 38 patients. This method has 90% sensitivity and 96% specificity. In the cases of normal transplanted kidneys, function correlation between doppler sonography and scanning was more than dysfunctioning kidneys.

BACKGROUND/AIM Ureteropelvic junction obstruction and vesicoureteral reflux are the most frequent entities identified on the basis of antenatal hydronephrosis. The aim of this study was to determine the incidence and pattern of abnormal renal scintigraphy findings in postnatal investigation of children with antenatal hydronephrosis. METHODS Twenty-four infants (19 boys and five girls) present...

The rate of clearance from the lung of the hydrophilic tracer molecule 99mTc DTPA was used to investigate the short-term effects on lung epithelial function when smokers switched to cigarettes with lower yields of tobacco smoke constituents. Two separate studies were performed. In the first study, subjects smoked conventional mid- and low-tar cigarettes. The second study used two specially manu...

Pulmonary clearance (Pcl) of aerosolized 99mTc-DTPA was studied in fourteen patients with primary ciliary dyskinesia (PCD), (median age 23.5 yrs, range 12-44 yrs) and nine normal individuals (median age 23 yrs, range 18-27 yrs). All had never smoked. Regional Pcl was studied for arbitrarily defined central and peripheral regions of the lung using a gamma camera method, whilst total Pcl was stud...

OBJECTIVE Dynamic renal scintigraphy complemented by late gravity assisted postvoid images to 60 minutes is a frequently used diagnostic test in the evaluation of hydrone¬phrosis. The objective of this study is to evaluate the effectiveness in acquiring images at 180 minutes to calculate the late output fraction (LOF) of 99mTc-DTPA in the diagnosis of ureteropelvic junction obstruction (UPJO). ...

The optimal management of children with antenatally diagnosed unilateral hydronephrotic kidneys is unclear. We have monitored renal function and drainage using 99mTc-DTPA renography in 77 children with such kidneys presenting at 1-14 mo of age with the aims of throwing light on the natural history of the condition and evaluating the response of the kidney to pyeloplasty. Since management was in...

FOR SEVERAL years an active program in human organ transplantation has been conducted at our institution (1-3), and since March 1962, 214 patients have received renal transplants. Two thirds of these transplanted kidneys are still functioning and most of these patients are living nearly normal lives. In addition, limited success has been achieved in liver transplantation (4-6). Of 14 recipients...
