In a prospective study 77 infants (35 boys) with a mean age of 5.23 months were studied to determine the value of sonography for detection of renal parenchymal involvement in urinary tract infection (UTI). Sonography was performed during UTI and about one month later. UTI was classified as upper and lower UTI according to the clinical and laboratory findings; radiological investigations (voiding cystoureterography = MCU) were performed in all infants. 40 infants were classified to have upper UTI. There was a high sensitivity (80%) and specificity (97%) for detection of renal involvement by sonography. Incidence for vesicoureteral reflux (VUR) was significantly higher in infants with repeated pathological findings on sonography. In contrast, no VUR was detected on MCU in all 12 infants with normal findings in both sonographic examinations. Yet, sonography without catheterization could not detect VUR in all infants with radiologically confirmed reflux. Our results show, that sonography is of definite value in infants with UTI, but cannot replace radiological work up.

D012680	Sensitivity and Specificity	Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)	Specificity,Sensitivity,Specificity and Sensitivity
D014463	Ultrasonography	The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.
