Renal scan in 73 year old female. The patient was injected with 10.0 mCi of technetium 99m MAG3 and time activity curves were generated. There is severely diminished perfusion to the left kidney which is mildly to moderately atrophic with hydronephrosis. Perfusion to the right kidney is fairly normal. The time to peak activity is 4 minutes for the right kidney and 5 minutes for the left kidney. The differential perfusion is 92% on the right and 8% on the left. There is rapid function and excretion of the right kidney with a T1/2 measurement of 5 minutes. The left renal curve continually increases during the exam with an extrapolated T1/2 measurement of 37 minutes. Findings consistent with obstructive uropathy on the left side with hydronephrosis and severely diminished perfusion and function. Normal examination of the right kidney. | |
