Anuric renal failure due to encasement of the ureters by lymphoma--ureteric obstruction without dilatation

Abstract

A case of anuric renal failure due to encasement of the ureters by tumour is described in a patient with advanced non-Hodgkin's lymphoma. In this patient as well as in two previously reported cases, the IVP showed delayed pyelogram and increasingly dense nephrogram on delayed films with little or no dilatation of the collecting systems. These radiographic features in a patient with extensive intra-abdominal tumour should strongly suggest the possibility of this unusual form of obstructive uropathy. Correct diagnosis in these cases may enable the administration of effective palliative treatment for the renal failure.
