Grade groups at diagnosis in African Caribbean men with prostate cancer: Results of a comparative study.

Background: There are no comparative data on pathological predictors at diagnosis, between African Caribbean and Caucasian men with prostate cancer (PCa), in equal-access centers. The objective of this study was to evaluate the grade groups of an African Caribbean cohort, newly diagnosed with PCa on prostate biopsy, compared with a Caucasian French Metropolitan cohort.

Methods: A retrospective, a comparative study was conducted between 2008 and 2016 between the University Hospital of Martinique in the French Caribbean West Indies, and the Saint Joseph Hospital in Paris.

Sexual steroids in serum and prostatic tissue of human non-cancerous prostate (STERPROSER trial).

Background: The specific involvement of the sex steroids in the growth of the prostatic tissue remains unclear. Sex steroid concentrations in plasma and in fresh surgical samples of benign central prostate were correlated to prostate volume.

Methods: Monocentric prospective study performed between September 2014 and January 2017.

Partial nephrectomy for renal tumors in solitary kidneys: postoperative renal function dynamics.

Objective: To describe renal functional outcomes after partial nephrectomy (PN) for a tumor in a solitary kidney using the estimated glomerular filtration rate eGFR (MDRD equation).

Patients And Methods: A retrospective review of 103 cases of PN in a solitary kidney at Memorial Sloan-Kettering Cancer Center from December 1989 to July 2010 was conducted. The postoperative eGFR measurements were broken into three timeframes: 1-10 days after PN, 10 days-8 weeks after PN, and 4-12 months after PN.

Risk stratification of metastatic recurrence in invasive upper urinary tract carcinoma after radical nephroureterectomy without lymphadenectomy.

Purpose: To assess the risk factors of metastasis relapse in pT2-3 upper tract urothelial carcinomas (UTUCs) treated by radical nephroureterectomy (RNU) without lymphadenectomy (LN).

Methods: A multicentric retrospective study was performed for pT2-3 pNx UTUCs treated by RNU between 1995 and 2010. The following criteria were retrieved: age, gender, American Society of Anaesthesiologists physical status, surgical approach, preoperative hydronephrosis, stage, grade, tumor location, surgical margin, lymphovascular invasion (LVI) status and outcomes.

The impact of lymph node status and features on oncological outcomes in urothelial carcinoma of the upper urinary tract (UTUC) treated by nephroureterectomy.

Purpose: Prognostic impact of lymphadenectomy during radical nephroureterectomy (RNU) for urothelial carcinoma of the upper urinary tract (UTUC) is controversial. Our aim was to assess the impact of lymph node status (LNS) on survival in patients treated by RNU.

Methods: In our multi-institutional, retrospective database, 714 patients with non-metastatic UTUC had undergone RNU between 1995 and 2010.

Environmental impact of minimally invasive surgery in the United States: an estimate of the carbon dioxide footprint.

Purpose: To attempt to quantitate the carbon footprint of minimally invasive surgery (MIS) through approximated scope 1 to 3 CO(2) emissions to identify its potential role in global warming.

Patients And Methods: To estimate national usage, we determined the number of inpatient and outpatient MIS procedures using International Classification of Diseases, ninth revision-clinical modification codes for all MIS procedures in a 2009 sample collected in national databases. Need for surgery was considered essential, and therefore traditional open surgery was used as the comparator.

Systematic classification and prediction of complications after nephrectomy in patients with metastatic renal cell carcinoma (RCC).

Unlabelled: Study Type - Harm (case series) Level of Evidence 4. What's known on the subject? and What does the study add? Radical nephrectomy for patients with metastatic renal cell carcinoma results in greater rates of morbidity than for those with less advanced disease. This study systematically characterizes complications associated with nephrectomy for metastatic RCC and identifies patient and disease characteristics that are associated with a greater risk of developing complications.

Selective arterial embolization for pseudoaneurysms and arteriovenous fistula of renal artery branches following partial nephrectomy.

Purpose: We describe the presentation, endovascular management and functional outcomes of 15 patients with renal arterial pseudoaneurysm following open and laparoscopic partial nephrectomy.

Materials And Methods: An institutional review board approved, Health Insurance Portability and Accountability Act compliant retrospective review of a prospectively maintained database revealed that 7 of 1,160 patients who underwent open partial nephrectomy and 8 of 301 treated with laparoscopic partial nephrectomy were diagnosed with a pseudoaneurysm of a renal artery branch between 2003 and 2010. Some cases were associated with arteriovenous fistula.

Small cell carcinoma of the upper urinary tract (UUT-SCC): report of a rare entity and systematic review of the literature.

Background: Primary small cell carcinoma of the upper urinary tract (UUT-SCC) is an extremely uncommon disease. The current knowledge of these rare tumors is mainly based on case reports or small series.

Methods: We reported two cases and performed a systematic literature search from 1970 to 2010 for articles on UUT-SCC.
