The initial dynamic images (a) as well as the prevoid (b) postvoid (c) and delayed (d) 3 h images of 99mTc-ethylene dicysteine diuretic renography in the patient showing no tracer clearance from both the kidneys with absence of visualization of tracer in either ureters or urinary bladder. The renogram (e) also showed an uprising curve for both kidneys

Uprising renograms of both kidneys indicate urinary obstruction [Figure 1].
Emergency noncontrast computed tomography (kidneys, ureters, and bladder) showing bilateral hydronephrosis (a) and renal calculi in the both distal ureters (b and c; arrows) suggesting acute ureteric obstruction. Double J stenting was done in both ureters which can be seen in the postintervention X-ray image (d)

An emergency double J stenting was done in both ureters, which relieved patients symptoms followed by normalization of urinary output [Figure 2].
Repeat 99mTc-ethylene dicysteine diuretic renography done 4 days after the procedure showing normal cortical function and drainage as suggested from the dynamic (a), prevoid (b), postvoid (c), delayed (d) images and the renogram curves (e)

A repeat 99mTc-EC diuretic renography done (with urinary catheter in situ) 4 days after the procedure showed normal cortical function and drainage from the left kidney and slow drainage from the right kidney [Figure 3] as suggested from the dynamic (a), prevoid (b), postvoid (c), delayed (d) images, and the renogram curves (e).
