Abstract
- PURPOSE
The aim of this study was to determine the role of renal ultrasonography in neonates with isolated preauricular tags.
METHODS
We performed a retrospective study of 10,997 newborn infants delivered from January 1995 to June 2003 in Wonkwang University Hospital. Nineteen newborns born with isolated preauricular tags were assessed for renal anomalies by performing renal ultrasonography within one week after birth. The study group was compared with a control group of 25 healthy neonates without preauricular tags during the same period, also using renal ultrasonography.
RESULTS
Preauricular tags were detected in 19 of 10,997(0.17%) neonates; 57.9% were found on the right side. Renal anomalies in neonates with isolated preauricular tags were detected in four infants (21.1%); this incidence was higher, but was not significant, compared with the control group. Types of anomalies were mild hydronephrosis of grade 1(3 cases) and 2(1 case) which were normalized within one year.
CONCLUSION
Routine renal ultrasonography is not recommended for newborn infant with isolated preauricular tags.
