—Dr Gordon appropriately emphasizes the importance of selective renal vein venography. We should have mentioned that, at the time the patient was seen, repeated attempts were made to enter the right renal vein, but the large clot extending around the superior to the vein prevented successful catheterization. The left renal vein was successfully entered, but retrograde flow could not be seen beyond the orifice.Dr Gordon is also correct in pointing out that the left renal vein, described as occluded following streptokinase infusion, was at least partially, if not totally, patent. Any confusion that has arisen because of this error is regrettable.We also would like to mention that, at the time our article was written, we were unaware of any previous reports on the use of thrombolytic therapy for renal vein thrombosis. We now know of its unsuccessful use in two previous reports.1,2 The significance of
