To evaluate whether diuretic agent administration on MR urography has an effect on renal length and to determine whether the increase in length can be used for the assessment of the renal function.

This retrospective study included 20 children (12 male, 8 female, age range 1-13 years). We measured the renal length changes due to diuretic injection on MR urographic studies and correlate these measurements with split renal function, which was calculated by nuclear scintigraphy. We used Wilcoxon Signed Ranks test to evaluate if the increase in length after diuretic injection is statistically significant. Spearman test was used to compare diuretic induced renal length changes with split renal functions.

We found that the increase in renal length after diuretic administration is statistically significant (p<0.05). The mean lengths for right kidneys before and after diuretic injection are 77,64 mm and 83,35 mm respectively. For the left side, these values are 80,39 mm and 87,86 mm.

We can estimate the functioning renal parenchyma on MR urography by assessing the renal length changes following diuretic injection.

Renal function may be estimated by comparing the length of the kidney before and after diuretic agent administration.
