Additional radiological examination of the patient. a Enhanced computed tomography showed renal artery (white arrow), tortuous dilated vessel in left renal hilum (green arrow), and early enhanced renal vein (blue arrow). b Enhanced computed tomography showed early enhanced left renal vein with ostial stenosis (blue arrow). c Enhanced computed tomography showed dilated lumbar vein (yellow arrow). d Enhanced computed tomography showed enhanced left varicocele (red arrow). e Digital subtraction angiography showed lumbar vein (yellow arrow), light contrast in the left gonadal vein (red arrow) after selective embolization of the segmental renal artery, and dilation of the left renal vein ostia (blue arrow)
