title: Inferior vena cava compression due to massive hydronephrosis from bladder outlet obstruction.
abstract: A 71-year-old man presented with acute urinary retention due to benign prostatic hyperplasia and was found to have computed tomography-documented mechanical obstruction of the inferior vena cava (IVC) due to massive hydronephrosis. Obstruction of IVC flow promptly resolved after bladder decompression.
