[Unusual metastasis of renal carcinoma]. / Metastases inhabituelles du cancer du rein.

Renal carcinoma, the third most common urological cancer, induces presence of metastases in 75% of cases. The most affected sites for metastasis are the lungs, the lymphatic system, bones, the liver, adrenal glands and the brain with sometimes a cancer free period of several years prior to evolutionary recurrence of the disease. The aim of this literature review is to report on secondary uncommon renal localizations by underlining their clinical significance, as well as main characteristics, in order to provide guidelines for effective patient diagnosis and therapeutic management.

Organ procurement from donors deceased from cardiac death: a single-center efficiency assessment.

Organ donation after cardiac death has been used for kidney and liver procurement in France since 2006. Until recently, most teams relied on in situ cold perfusion to prepare the donor before organ retrieval. Our team has used since 2007 normothermic abdominal recirculation. While this technique is presumed to be more difficult to implement, it also ensures a lower rate of primary nonfunction when compared to in situ cold perfusion. We present the efficiency results of our organ donation after cardiac death program. After 3 years, we have been able to establish a program in which we use normothermic abdominal recirculation in 97% of donors after cardiac death. The yearly efficiency of this program is comparable to the national efficiency of organ procurement from conventional deceased donors in France.

Kidney transplantation in HIV-positive patients: report of our first 7 cases.

INTRODUCTION: Infection with human immunodeficiency virus (HIV) is associated with end-stage renal disease (ESRD). Although many teams initially were reluctant to offer kidney transplantation as a therapeutic option in HIV-positive patients with ESRD, new drug regimens introduced in the late 1990s have dramatically improved the life expectancy in these patients. OBJECTIVE: To report the results of the first 7 kidney transplantation procedures in HIV-positive patients at our institution. PATIENTS AND METHODS: Patients were selected to minimize the risks of HIV disease progression, opportunistic infections, and tumors. Protease-inhibitor therapies were suspended because of possible interaction with immunosuppression drugs. The induction regimen did not include lymphocyte-depleting drugs. After undergoing transplantation, patients were monitored by the transplantation and infectious disease teams. RESULTS: To date, all patients are alive with functioning grafts. We did not observe any episodes of acute rejection, and there were few adverse events. Drug tolerance was good for both immunosuppression and antiretroviral therapies. CONCLUSION: Kidney transplantation in HIV-positive patients with ESRD is warranted. Provided that patients are carefully selected, good results can be achieved with few adverse events, episodes of acute rejection, and drug interactions. Posttransplantation, these patients must be closely monitored by both the transplantation and infectious diseases teams to ensure optimal management.
