Massive post-obstructive diuresis in a patient with Burkitt's lymphoma.

Burkitt’s lymphoma, which originates from B-cells, is commonly a disease of children, although it is also frequent amongst immunodeficient adults. It is the non-endemic form that affects adolescents and young adults, usually presenting with abdominal disease causing constipation, pain, nausea and vomiting [1]. This tumour, one of the very aggressive lymphomas, has the highest growth rate of all of them, and it responds well to chemotherapy. Acute renal failure occurs frequently in Burkitt’s lymphoma, and uric acid nephropathy is its most common cause. We report here on a case of Burkitt’s lymphoma with acute obstructive renal failure, the relief of which resulted in massive polyuria, reaching 90 l a day.
