Plain-English summary
A group of dogs with kidney stones (nephroureterolithiasis) underwent a special imaging test called diuretic renal scintigraphy to check for any blockages in their urinary tract. Most of the kidneys showed no obstruction, while a few indicated potential blockages. The test helped veterinarians determine which dogs might need further treatment for their kidney issues. Overall, this imaging technique proved helpful in identifying urinary tract problems, but additional tests may be needed for dogs with severely impaired kidney function.

Abstract
This study evaluated the results of diuretic renal scintigraphy in dogs with urolithiasis. Eighty-three kidneys with nephroureterolithiasis +/- renal pelvis/ureteral dilation were included in the study. Sixty-three kidneys showed a non-obstructive pattern, with a steep drop or gradual downward slope of renal time-activity curve (TAC). Excretion half-time of radiopharmaceutical (T(1/2)) was 3.99 (2.99 to 7.95) min. Three kidneys showed an obstructive pattern, with continuous rise of the TAC and median T(1/2) of -10.71 (-5.20 to -17.56) min. Fifteen kidneys had non-diagnostic studies characterized by flat TAC. Individual kidney glomerular filtration rate was <0.5 mL/min/kg body weight in most non-diagnostic studies. Diuretic renal scintigraphy appears to be a useful adjunct modality to rule out or confirm ureteral obstruction in dogs. Additional diagnostic procedures may be necessary to achieve a definitive diagnosis in cases of severely impaired renal function.
