Abstract

OBJECTIVE
The purpose of this study is to evaluate other anomalies associated with the fetal renal dysgenesis and prognosis. METHODS: Level II sonography were reviewed in the pregnant women who had been diagnosed with fetal renal dysgenesis antenatally from March 1998 to February 2005. Diagnosis was comfirmed by the autopsy or the postnatal studies including sonographic and radiologic evaluation. RESULTS: Thirty fetuses had a fetal renal dysgenesis. There were 2 cases of polycystic kidney, 4 cases of bilateral renal agenesis, 4 cases of unilateral renal agenesis, 3 cases of bilateral multicystic dysplastic kidney and 17 cases of unilateral multicystic dysplastic kidney. The common associated anomalies were congenital heart disease (7 cases), single umbilical artery (5 cases), imperforate anus (2 cases) and tracheo-esophageal fistula (2 cases). Hypospadia and scoliosis with hemivertebra were also noted. CONCLUSION: The most common anomaly associated with renal dysgenesis was congenital heart diseases. If fetal renal dysgenesis is detected antenatally, fetal echocardiography should be performed.
