title: Case report. Unilateral renal vein thrombosis without proteinuria.
abstract: Unilateral renal vein thrombosis occurred in a patient who was found to have an adenocarcinoma and who had previously been subjected to trauma. Proteinuria was absent throughout the patient's entire clinical course, despite its well known association with renal vein thrombosis. However, other findings suggestive of renal vein thrombosis, including back pain and tenderness, hematuria and an enlarged kidney were present. It is clear that proteinuria need not be the only signal to occasion a search for renal thrombosis. This case probably constitutes the second report of absent proteinuria when thrombus forms within renal vein.
