Left renal vein hypertension is a most uncommon and rarely a well-docu
mented cause of gross hematuria. We report a case of lateralizing, gro
ss hematuria, resulting from left renal vein hypertension in an indivi
dual with a history of a prior Whipple procedure. The diagnosis was su
spected at the time of renal angiography and proven by renal venograph
y. Complete rapid resolution of the hematuria and hypertension was ach
ieved following placement of a left renal vein stent.
