title: Bilateral Maternal Pelvic Kidneys Presenting as a Tumor Previa: Sonographic Diagnosis and Obstetric Management.
abstract: Renal ectopia occurs when the kidney fails to ascend normally to the retroperitoneal renal fossa. Bilateral cases have also been reported but are very rare. Pregnancy and labor with maternal renal ectopia provides a unique challenge to the obstetricians attempting to prevent damage to the kidneys during labor and allow safe delivery. We describe a case of congenital bilateral pelvic kidneys assessed and diagnosed by 3D sonography as "tumor previa" and managed accordingly.
