Conventional creatinine clearances involving urine collections over 2, 4 and 24 hours and creatinine clearance predicted from plasma creatinine concentrations without urine collection were compared to glomerular filtration rate (GFR) estimated by 99mTc DTPA clearance in 171 patients with a wide range of GFR. All creatinine clearance methods involving urine collection had standard errors of the ...

Pulmonary permeability was assessed using the technique of 99mTc (technetium-99m) diethylene triamene pentacetic acid (DTPA) aerosol transfer in 10 patients who had antibodies to human immunodeficiency virus (HIV) and were non-smokers and in 20 HIV antibody positive smokers. Five patients had Pneumocystis carinii pneumonia (PCP) proved by transbronchial lung biopsy; four were non-smokers and on...

Although a role for the airway circulation in the clearance of inhaled particles is generally assumed, there is little information to confirm its importance. We studied the effects of decreased bronchial blood flow on the uptake of the soluble tracer technetium=99m-labeled diethylenetriamine pentaacetic acid (99mTc-DTPA) from subcarinal airways in sheep (n = 7). The bronchial artery was cannula...

A 53-year-old male was found to have hypertension caused by the significant secretion of renin from an atrophic left kidney. He had undergone extracorporeal shock-wave lithotripsy (ESWL) for left renal lithiasis 11 years previously. A renal dynamic study with 99mTc-diethylenetriaminepentaacetic acid (DTPA) indicated that the rate of renal excretion and uptake was decreased in the left kidney an...

A 45-year-old man presented with loin pain and burning micturation. He had a positive Bilharzial titre and impaired renal function. Ultrasonography (USG) revealed right hydroureteronephrosis and a thickened bladder wall with areas of calcification. A diuretic 99mTc – DTPA scan (technetium-99m diethylene triamine penta acetic acid) showed features of obstruction in both the kidneys. Cystoscopy s...

OBJECTIVE The purpose of this study was to develop a simpler method to measure severely reduced glomerular filtration rate (GFR) for patients with a GFR below 30 mL/min. METHOD The GFR was measured in 24 patients using both the 51Cr EDTA slope-intercept method (the conventional method) and 99mTc-DTPA with our proposed simpler GFRn method. RESULTS The correlation coefficient was 0.92 between...

BACKGROUND The clinical significance of MTT and PTT, determined by deconvolution of renographic curves, is arguable. Their usefulness in diagnosis of obstructive uro- and nephropathy, renovascular hypertension and monitoring of transplanted kidneys is pointed out, but susceptibility of deconvolution methods to errors resulting from "statistical noise" is also stressed. So far there are no repor...
