Abstract

Introduction: It has been suggested that calculation of DIFFERENTIAL RENAL FUNCTION (DRF) using 99m Tc-DMSA may lead to overestimation of the function of an obstructed kidney. The aim of this study was to evaluate the effect of DIURETIC administration on the determination of DRF using 99m Tc-DMSA scintigraphy in patients with dilated pelvis.Methods: Thirty three patients, aged from 2 months to 66 years (19.27±20.83 years, 22 males, 11 females), in whom unilateral hydronephrosis had been documented by ultrasonography and DIURETIC RENOGRAPHY were included in the study. 99MTC-DMSA scintigraphy was performed in all patients 3 hours after tracer injection. Immediately after the standard study, furosemide was injected in all patients, and 30 min later anterior and posterior images were obtained. DRF was calculated for each patient and from each 99m Tc-DMSA study by using the geometric mean method.Results: We did not observe any significant difference in all patients between the DRF values obtained before and after DIURETIC administration (the DRF value of the affected kidney was thus taken into account)(P=0.35). When we compared DRF values obtained from standard and from DIURETIC DMSA studies, the mean of the differences was only 0.18% and the SD was only 1.09%. In 17 patients (group1), diuresis RENOGRAPHY revealed an obstructive curve pattern while 16 patients (group 2) had a nonobstructive dilated renogram curve pattern. There were again no significant differences between DRF values obtained before and after DIURETIC injection in each groupConclusion: In view of our study, DIURETIC administration seems to be an unnecessary intervention because it has no effect on the accuracy of DRF measurements using 99m Tc-DMSA scintigraphy in patients with a dilated collecting system whether it is obstructed or not.
