Congenital anomalies now account for a large percentage of infant deaths.1 Clinically significant congenital anomalies of the genitourinary tract are relatively common. A study from Buffalo, NY, in 1988 demonstrated that 1.37% of unselected, otherwise healthy infants will have a urinary tract anomaly seen on ultrasonography that may require operative repair.2 The first clinical manifestation of many genitourinary anomalies is a urinary tract infection (UTI) during infancy, which presents as fever, vomiting, or irritability.3 Even when detected early, these anomalies can sometimes result in significant early morbidity or death. This is demonstrated by the following case report.
