Chronic post-thrombotic obstruction of the inferior vena cava: both renal veins being the cause of painless gross hematuria from pelviureteral mucosal varices in normal functioning kidney.
A 31-year-old man presented with painless gross hematuria. His serum-creatinine level was within the normal range. Abdominopelvic CT showed an infrahepatic calcified fibrous cord, which was suggestive of inferior vena cava (IVC) remnant. Extensive venous collateralization around both kidneys and venous drainage of the extremities via the inferior epigastric and internal thoracic veins were shown. We report a case of chronic post-thrombotic obstruction of the IVC, involving both renal veins, which was believed to be the cause of painless gross hematuria from mucosal varices of the pelviureteral system in normal functioning kidney.
