Bellini duct carcinoma is a very rare type of renal cell carcinoma (RCC), accounting for less than 1%. It arises from the distal nephron, more specifically from the collecting duct. Its morphological features are extremely variable, making its diagnosis difficult. We report the case of a 62-year old patient admitted with a painless progressive left flank swelling. CT scan showed a huge mass occupying the upper portion of the left kidney. The patient underwent radical nephrectomy. Anatomopathological examination showed collecting duct carcinoma of the kidney...

PURPOSE: Renal cancer surgery (RCS) can adversely impact long-term function and survival. We evaluate predictors of chronic kidney disease (CKD) at 5-years and non-renal cancer mortality (NRCM) 10-years after RCS. MATERIALS AND METHODS: We analyzed 4,283 patients undergoing RCS (1997-2008). Radical nephrectomy (RN) and partial nephrectomy (PN) were performed in 46%/54% of patients, respectively. Cumulative probability ordinal modeling was used to predict CKD status 5-years after surgery and multivariable logistic regression for predicting NRCM at 10-years...

OBJECTIVES: Obesity, typically defined as a body mass index (BMI)≥30kg/m(2), is an established risk factor for renal cell carcinoma (RCC) but is paradoxically linked to less advanced disease at diagnosis and improved outcomes. However, BMI has inherent flaws, and alternate obesity-defining metrics that emphasize abdominal fat are available. We investigated 3 obesity-defining metrics, to better examine the associations of abdominal fat vs. generalized obesity with renal tumor stage, grade, or R...

REVIEW

Increased early and incidental detection, improved surgical techniques and technological advancement mean that the management of renal mass lesions is constantly evolving. The treatment of choice for renal mass lesions has historically been radical nephrectomy. Partial nephrectomy is now recommended for localised renal masses, owing to favourable renal functional outcomes. Ablative renal surgery confers a significant risk of chronic kidney disease. There are few studies assessing long term outcomes of nephrectomy on renal outcomes, and virtually no studies assessing long term outcomes for less invasive therapies such as ablation...

PURPOSE: We sought to determine whether median household income (MHI) independently predicts surgical approach (partial vs. radical nephrectomy) and survival in patients with renal cell carcinoma. METHODS: The U.S. Surveillance Epidemiology and End Results Database (1988-2011) was queried to examine kidney cancer cases and linked to the Area Health Resources File. We correlated surgical approach and survival, both overall and cancer-specific, with tumor stage, age, race, sex, and income data...

Partial nephrectomy is the gold standard for the renal tumours less than 7 to 10cm whenever feasible in order to preserve renal function. The extension of nephron-sparing surgery using a mini-invasive approach is possible by robotic surgery. Radical nephrectomy is mandatory in the other situations and especially in case of locally advanced renal carcinoma. The place of cytoreductive nephrectomy in metastatic renal cell carcinoma is the purpose of the CARMENA trial. Tyrosine kinase inhibitors are currently the first line treatment; but in the near future new immunotherapy by checkpoints molecules could crucially change the treatment of metastatic renal cell carcinoma...

Radical nephrectomy is associated with a progressive decline in renal function. Clinical parameters in post-nephrectomy insufficiency were described but the impact of histopathologic vascular findings in the non-neoplastic kidney of nephrectomy specimen, has been poorly studied. Our aim was to evaluate whether the severity of atherosclerosis in non-neoplastic renal tissue predicts the evolution of glomerular filtration rate in patients undergoing total nephrectomy. Thirty-one non-donor patients with unilateral radical nephrectomy were included...
