Introduction: Despite considerable therapeutic advances in the last 20 years, metastatic cancers remain a major cause of death. We previously identified prominin-2 (PROM2) as a biomarker predictive of distant metastases and decreased survival, thus providing a promising bio-target. In this translational study, we set out to decipher the biological roles of PROM2 during the metastatic process and resistance to cell death, in particular for metastatic melanoma.

Compared to primary tumors, there are still limited genomic data that has been obtained from metastatic samples.
Methods: We aimed to characterize metastatic ccRCC by way of whole-genome analyses of metastatic formalin-fixed samples, using OncoScan technology.
Radical cystectomy with urinary deviation is performed increasingly in France. Ileal conduit ureteral diversion (ICUD), described by Bricker and widely used after this type of radical resection, leads to substantial anatomic modifications that are potential danger zones during subsequent gastro-intestinal or urinary tract operations. Injury to the urinary diversion apparatus can lead to disastrous complications in these patients who are often elderly and frail.

The symptomatology is characterized by the appearance of pain, perineal edema and an induration of the root of the penis, which do not concern the distal part of the penis or the glans. MRI is the best complementary examination.

HLRCC results from heterozygous germline mutations in the tumour suppressor fumarate hydratase (FH) gene.
Methods: As part of the French National Cancer Institute (INCa) 'Inherited predispositions to kidney cancer' network, sequence analysis and a functional study of FH were preformed in 56 families with clinically proven or suspected HLRCC and in 23 patients with isolated PRCCII (5 familial and 18 sporadic).
The authors report the case of a patient aged of 27 years who presented in the past a testicular torsion with loss of the ipsilateral testis and fixation of the contralateral one. Ten years later, he presented with pain on the remaining testis, which evolved to necrosis, and led to a second orchidectomy. In retrospective, it appears that the assumption that the testis had been adequately fixed ten years earlier led to the loss of the remaining testis.

Cutaneous and uterine leiomyomas are the most common clinical manifestations of HLRCC, whereas only approximately 20% of the families display renal cell cancer (RCC). The number of RCC cases in these families varies from one to five.

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.
Background: Immunosuppressive therapy has many side effects among which is an increased infectious risk for the recipient. Transmission of pathogens from the graft to the recipient has not been well evaluated; there are no guidelines regarding the need for microbiological tests on the graft prior to transplantation. We routinely performed such tests to evaluate the risk and determine whether a patient should receive preemptive antibiotic therapy after transplantation.

Materials And Methods: The case files of 1825 neurological patients followed in our department between 2000 and 2006 were retrospectively reviewed. The following data were recorded in patients with bladder tumour: age, gender smoking, aetiology of the neurological disease, voiding mode, history of neurogenic bladder, mode of discovery, histological type, grade, TNM stage, treatment and outcome.

Subject: This article reports preliminary findings relating to the use of a new preservation solution, the Solution de Conservation des Organes et des Tissus (SCOT), in renal transplantation. This fourth-generation solution combines an extracellular-like composition with 20 kDa polyethylene-glycol, known for its cell-protection capacity and immunocamouflage properties.
Methods: We have reported preliminary data obtained in 29 transplantations (25 cadaveric donors and 4 living related donors) between December 2004 and November 2005.
Introduction: Creation of a vascular access (VA) for haemodialysis is a surgical procedure which comprises a failure rate related to the quality of the vessels and the operator's experience. The authors report the first 2 years of a young urologist's experience with this procedure in a local hospital in collaboration with the nephrology team.
Patients And Methods: Patients undergoing creation of VA were divided into 2 chronological groups.
The presence of urinary tract obstruction affects the proximal urinary tract by altering renal filtration and excretion functions, resulting in accumulation of electrolytes. Many pathophysiological mechanisms are also involved during obstruction and may be expressed secondarily. For example, relief of obstruction, which restores free flow of urine, is accompanied by marked diuresis and electrolyte disorders.

Although the patient presented a vesico-vaginal fistula, the presence of air in the bladder wall and only in the bladder lumen, confirmed the diagnosis of emphysematous cystitis. Despite intensive care and surgery with colostomy and Mikulicz drainage associated with urinary diversion (transparietal bladder catheter on one side and cutaneous ureterostomy on the other side), the patient died on day 10 in a context of sepsis.
