A lot of congenital anomalies are detected in fetus and newborn through the use of prenatal and postnatal ultrasonography. This study aimed to assess the renal duplication incidences in neonates and provide solutions that would help in managing these patients. From January 1, 2001 to December 31, 2010, we retrospectively analyzed 113 patients with neonatal duplication of the renal collecting system who were diagnosed prenatally and confirmed postnatally kidney ultrasonography at single center. In this case, the duplication of the renal collecting system is the most common congenital malformation of the urinary tract with an incidence of 0.12%, which is lower than the general incidence of 1%. Out of the total 113 patients, the incomplete duplication kidney findings were 85 patients (75%) and complete duplication kidney findings were 18 patients (15.9%). As to whether they had other congenital anomalies, 13 out of 85 patients had incomplete duplication of the kidney and all of 18 patient had complete duplication of kidney. In our study, if there are no accompanying complications, we suggest that observing ultrasonography is sufficient without other evaluation to detect whether they are complete or incomplete.
