Sir.—I am writing in reference to the article by Emanuel and Aronson, which appeared in the August issue of the Journal (128:204,1974). Six of the seven patients referred to with hematuria and renal vein thrombosis were treated with nephrectomy. The series includes a review from 1950 to 1967 and does not conform to the present philosophy of care of patients with renal vein thrombosis. Subsequent to this time period, a nonsurgical approach to renal vein thrombosis has been followed—the results being as satisfactory as those reported with nephrectomy in terms of survival and more satisfactory in terms of renal function.1
Controversy may still exist regarding the treatment of patients with bilateral renal vein thrombosis; however, it is my impression that these patients, too, do better without the benefit of surgical intervention.
