Abstract
- Recently, with the advent of prenatal ultrasonography, renal tumors in the neonatal period are diagnosed with increasing frequency. Detected most solid masses in the neonatal kidney will mostly be proven to be a congenital mesoblastic nephroma but a Wilms' tumor in the neonate is quite uncommon. We found a solid mass in the fetal left kidney at 39th week of gestation by prenatal ultrasonography. The infant, a healthy male in external appearance was delivered by Cesarean section at 40th week of gestation. At one day of age, we confirmed a left renal mass with ultrasonography and this neonate underwent left nephrectomy at nine days of age. The tumor was pathologically diagnosed as stage 1 with favorable histology of Wilms' tumor. Chemotherapy was performed postoperatively according to the EE-regimen of National Wilms' Tumor Studies (NWTS)-4 for 24 weeks. Now the patients is in good condition with no recurrence after postoperative 17 months.
