Current Issues in the Diagnosis and Management of Wilms' Tumor
October 01, 1996
Dr. Paulino has written an excellent review of our present knowledge of Wilms' tumor. Not everyone would agree, however, that ultrasound has replaced the intravenous pyelogram (IVP). The National Wilms' Tumor Study Group (NWTSG) recommends IVP together with real-time ultrasonography as the preoperative imaging studies for the abdomen. The former is used to establish the presence of a functioning opposite kidney and of any congenital abnormality. The latter identifies the presence and status of inferior vena cava thrombi.
