Effects of radiofrequency ablation on individual renal function: assessment by technetium-99m mercaptoacetyltriglycine renal scintigraphy.
We quantitatively evaluated total and individual renal function by technetium-99m mercaptoacetyltriglycine (Tc-99m MAG3) renal scintigraphy before and after radiofrequency ablation (RFA) of renal tumors. Eleven patients who underwent Tc-99m MAG3 renal scintigraphy 1 week before and after RFA were evaluated (7 men and 4 women; age range: 23-83 years; mean age: 60.6 years). Five patients had soli...
متن کاملCreatinine clearance in renal disease. A reappraisal.
To determine the validity of endogenous creatinine clearance as a measure of glomerular filtration rate in patients with renal disease 308 simultaneous determinations of inulin clearance and endogenous creatinine clearance were reviewed and analysed. The ratio of creatinine clearance/inulin clearance increased progressively with the decline in inulin clearance, while the finding of a normal end...
متن کاملEstimation of Creatinine Clearance in Patients with Unstable Renal Function
Measurement of creatinine clearance (CCr) has long been a problem in sick patients, largely because of the need to collect a carefully timed urine specimen to determine it. However, a number of years ago, several methods were developed to estimate CCr without a urine specimen [1-4]. However, all these approaches only considered the situation where serum creatinine was stable. Because of this, a...
متن کاملAssessment of renal function by inulin clearance: comparison with creatinine clearance as determined by enzymatic methods.
We compared creatinine clearances determined by enzymatic (Kodak Ektachem 700 single-slide, Boehringer Mannheim creatinine PAP) and nonenzymatic (Jaffé, HPLC) methods with glomerular filtration rate measured by inulin clearance in patients with varying degrees of renal function. The Kodak enzymatic assay gave values for creatinine 2 to 3 mg/L higher than the other methods. This resulted in sign...
متن کاملA camera based calculation of 99mTc-MAG3 clearance using conjugate views method [Persian]
Background: Measurement of absolute or differential renal function using radiotracers plays an important role in the clinical management of various renal diseases. Gamma camera quantitative methods in approximation of renal clearance may potentially be as accurate as plasma clearance methods. However some critical factors such as kidney depth and background counts are still troublesome in...
