Relative renal accumulation of Tc-99m penicillamine as an index of differential renal function: concise communication
Abstract:
The relative renal accumulation of technetium-99m penicillamine (TPEN) was evaluated as an index of differential renal function. Using a scintillation camera interfaced to a computer, renal uptake of TPEN was determined for each kidney by subtracting the renal activity at 10 min from that at 25 min. This percentage of TPEN activity in the left kidney was compared with the percentage of total creatinine clearance contributed by the left kidney in six patients with ureteral obstruction and nephrostomy drainage. The two measurements agreed extremely well, with a correlation coefficient of 0.98. The relative renal uptake of TPEN and similar cortex imaging agents such as Tc-99m dimercaptosuccinic acid can probably be used to assess differential renal function.

Renal Drug Clearance: Overview
Renal clearance can be calculated using different methods. One approach is to divide the urinary drug excretion rate by the plasma drug concentration. This method directly measures renal clearance, indicating the kidneys' efficiency in...
Renal Drug Clearance: Comparison Between Renal Excretion Methods
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...
Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
