Absence of a renal sinus echo complex in the ectopic kidney of a child: a normal finding.
The typical urographic and anatomic appearance of the extrarenal pelvicalyceal system of the normal ectopic kidney has been thoroughly described. We report the ultrasonographic correlate of this distinct configuration. The normal central renal sinus echo complex was absent in two thirds of the ectopic kidneys in this series. In the remaining one third, the sinus echo complex was eccentric.
