Evaluation of Renal Function using Renal Scintigraphy

Abstract

This study was carried out in order to evaluate renal function using renal scintigraphy with the creatinine clearance used as a reference The sample of this study included 50 patients with result of GFR using renal scintigraphy and creatinine clearance, the main objective was to evaluate renal function using renal scintigraphy and creatinine clearance.99mTc-DTPA were administered to the patient intravenously and gamma camera is used to detect the count and then GFR was calculated , serum creatinine test result was used to calculate an estimation for GFR using a mathematical formula that involve the patient age and BMI in order to get an accurate estimation. The results showed that the renal scintigraphy GFR and the creatinine clearance results have strong linear correlation with correlation coefficient of 0.88. It also showed that the GFR is inversely associated with the patient age and BMI with correlation coefficient of 0.75 and .74 respectively. In conclusion nuclear medicine renography is an accurate and reliable test that makes it the test of choice for all the patients with renal function diseases.It is recommended for the urologists to consider using renography in order to have a satisfactory picture of renal function. Also recommended for future researchers to have a larger sample for making stander GFR according to patient’s age and body mass.
