title: A rare case of renal vein thrombosis due to urinary obstruction.
abstract: Renal vein thrombosis (RVT) is an uncommon condition in adults and may be caused by endothelial damage, stasis, or hypercoagulable states. RVT is commonly identified in patients with nephrotic syndrome or malignancy. We present the case of a 57-yearold man with no past medical history who presented with a 1-month history of abdominal pain, dysuria, and hematuria. Initial laboratory studies were consistent with acute kidney injury (AKI). Imaging revealed bladder distension, enlargement of the prostate, bilateral hydronephrosis, and left renal vein thrombosis extending into the inferior vena cava. His renal failure and presenting symptoms resolved with placement of a Foley catheter and ureteral stent. The patient was discharged on anticoagulation. Here, we report a rare case of RVT that appears to have occurred as a consequence of obstructive uropathy causing massive bladder distention resulting in compression of the renal vein.
