호두까기 증후군에서 정맥신우조영술로 진단된 요관주위 정맥류

Renal pelvic and periureteral varices are rare cause of hematuria. On the intravenous pyelography, periureteral varices show a scalloped corkscrew-like appearance to the ureter without evidence of proximal obstruction. The cause of these varices includes renal vein thrombosis, obstruction of the inferior vena cava, congenital anomalies of the inferior vena cava or renal veins, infection, malignancy and nutcracker syndrome. We report a case of Periureteral Varices Diagnosed by Intravenous Pyelography caused by nutcracker syndrome.
