Split Renal Function Using 99mTc-DTPA Versus 99mTc-DMSA in Kidney Patients of Wide Age Ranges.

Overview

To evaluate split renal function using Tc-99m DTPA versus Tc-99m DMSA.

Split renal function (SPR) is a determination of the relative contribution of each of the two kidneys . It gives a useful information in several conditions such as evaluating unilateral renal disorders, assessing individual kidney function before and after intervention, and before live donor nephrectomy. Different radiopharmaceuticals such as technetium-99m dimercaptosuccinic acid (99mTc-DMSA), technetium-99m diethylenetriaminepentaaceticacid (99mTc-DTPA), technetium-99m mercaptoacetyltriglycine (99mTc-MAG3), Iodine 131 orthoiodohippurate and more recently technetium-99 m ethylenedicysteine (99mTc-EC) were used, However, 99mTc-DMSA as a static renal agent is considered the most reliable method to measure relative renal function and the most appropriate tracer for renal cortical imaging . In some papers, it is emphasized that relative renal function calculated with 99mTc-DTPA is as reliable as 99mTc-DMSA .‬ The investigators design the study to evaluate the difference in estimation of split renal function using the available two radiopharmaceuticals: Tc-99m DTPA and Tc-99m DMSA.
