Abstract
Background: Diuretic renography using 99mTc-mercaptoacetyltriglycine (99mTc-MAG3) is a relatively non-invasive technique and has been increasingly used as a reliable technique for the evaluation of kidney function in a wide range of kidney disorders. Methods: In this retrospective study, we retrieved the medical records of patients referred to the Radiology Department of Radiology, King Abdulaziz Specialist Hospital, Taif, Saudi Arabia, with suspected kidney disease and underwent 99mTc-MAG3 diuretic renography during January 2020 to November 2021. Results: The medical records of 260 patients were retrieved. Most of the patients had either suspected obstructive (n = 80; 30.7 %) or non-obstructive hydronephrosis (n = 60; 23.1 %). The left kidney was affected in more than half of the patients (n = 155; 59.6 %). In terms of split kidney functions, the right kidney had a median function of 50.9 (38.5–75.5); overall, 39 patients (69.6%) had good right kidney function. The left kidney had a median function of 49.4 (24.5–61.5); overall, 33 patients (58.9%) had good left kidney function. Conclusion: Radioisotope renography is useful for assessing kidney functions in real-life settings. The present study’s results indicate that radioisotope renography using 99mTc-MAG3 is helpful in the visual interpretation of kidney failure, obstructive uropathy and kidney stenosis.
