[Comparison between scintigraphy, B-mode, and power Doppler sonography in acute pyelonephritis in children].
OBJECTIVE
Comparing Power Doppler imaging versus technetium-dimercapto-succinic-acid (Tc-DMSA) scintigraphy in acute pyelonephritis of childhood.


METHODS



METHODS
First episode of urinary tract infection, clinical and biological findings suggesting an upper lesion, absence of urological malformation or obstruction, absence of reflux (or vesico-ureteral reflux inferior to grade 3). Number of patients: 49, length of the study: 26 months (from November 95 to January 98).


METHODS
Tc99m-DMSA scintigraphy (after five days), B mode and Power Doppler imaging (on the day of admission or the following day). Systematic cystography (day 5 to day 30).


RESULTS
In terms of positive diagnosis, scintigraphy was superior to Power Doppler, and the latter was superior to B mode ultrasonography. Sensitivity (scintigraphy being the gold standard) was equal for both B mode and Power DopplerUS imaging, but combined Power Doppler and B mode US provided improved results.


CONCLUSIONS
Currently, the results with Power Doppler imaging are insufficient to replace DMSA scintigraphy. However, Power Doppler is a good complement to B mode US.
