A 22-year-old woman was admitted to Osaka University Hospital with complaints of gross hematuria and subfever. Laboratory data showed no particular changes except for mild anemia and hematuria. The incomplete duplex of the right upper urinary tract and marked scalopping of the left ureter were noted on excretory urography. Cystoscopic examination revealed bleeding from the left ureteral orifice, but the clear urine was obtained from the renal pelvis by catheterization. Selective left renal angiography demonstrated normal renal arterial network but dilated vein running around the left ureter was detected on venous phase. At the time of operation the left ureter was surrounded by tortuous dilated vein which seemed draining a segment of the kidney. This vein was resected with successful result in disapperance of hematuria. Postoperative IVP showed the ureter turned to the normal appearance. Previously reported cases were reviewed and the possible causes of the lesion were discussed including vascular malformation.
