Objective: The aim is to assess the rate of coexistence of renal and cardiac anomalies in children with isolated preauricular tags and to determine whether routine evaluation for such associated malformations is warranted. Methods: All children presented to the outpatients clinic with the complaint of isolated preauricular tag were prospectively included in the study between the years 1995-2004. Syndromic children were excluded. Urinary tract ultrasonography (USG) and cardiac evaluation were employed in all. Results: The study included 46 children. The median age was 36 months (range, 2 months to 10 years), excluding four newborn. There were 30 (65%) males and 16 (35%) females. USG examination revealed two (4%) patients with pelvicalyceal dilatation, one of which resolved spontaneously. The other patient proved to have a ureteropelvic junction obstruction and underwent corrective surgery. Cardiac evaluation yielded an atrial septal defect in one (2%) child. Another one had Wolf-Parkinson-White Syndrome which is not a congenital cardiac malformation but rather a pre-excitation syndrome. Conclusion: The present study supports the data favoring routine use of USG to evaluate UT in children with isolated preauricular tags. However, more prospective studies incorporating larger sample sizes are needed before offering routine cardiac evaluation in these children.
