Abstract
Introduction: Urinary obstructive disease is one of the most common disorders in urinary system. Dilatation which is detected by sonography, is a key finding in obstruction in most of the cases, also could be found following surgery, lithotripsy and vesico–urethral reflux. Radioistope diuretic washout renography is a useful method to differentiate mechanical and non mechanical obstruction. Materials & Methods: 20 patients were studied with diuretic renography. They were hydrated and emptied their bladders before study. 99mTc–DTPA was injected in supine position for each patient. Images were obtained in 1 min time interval. Then 40 mg furosmide was injected at minute 16th intravenously and sequential imaging were continued for another 20 minutes. Subsequently time activity curves and images were analyzed. Results: Among 20 patients, 8 had urinary stones, 9 uretro-pelvic junction stenosis, 2 posterior urethral valve and one case with single kidney. Results showed 13 mechanical and 7 non – mechanical obstruction. Sensitivity of the procedure was 85%. Conclusion: This study revealed that diuretic radionuclide renography is a sensitive and simple method for diagnosis of urinary obstruction.
