[Severe hemorrhagic cystitis following allogenic bone marrow transplantation].

The authors report the case of a 25-year-old woman with a history of acute lymphoblastic leukaemia in complete remission after being treated, three years previously, by chemotherapy, radiotherapy and allogeneic bone marrow transplantation, who was admitted to the urology department following an episode of haematuria with severe anaemia. This clinical case report illustrates the diagnostic and therapeutic approach adopted in relation to the severity of the haematuria, in which haemostatic surgery was only considered as a last resort.
