OBJECTIVE To determine clinical or pathologic features associated with ipsilateral recurrence after NSS performed for renal cell carcinoma (RCC). DESIGN, SETTING, AND PARTICIPANTS We analysed 809 NSS procedures performed at(More)
BACKGROUND Although high throughput technologies for gene profiling are reliable tools, sample/tissue heterogeneity limits their outcomes when applied to identify molecular markers. Indeed, inter-sample differences in cell composition contribute to scatter the data, preventing detection of small but relevant changes in gene expression level. To date,(More)
OBJECTIVES The common subtypes of renal tumors are conventional or clear cell carcinoma, papillary carcinoma, chromophobe carcinoma and oncocytoma. Each subtype has its distinct histogenesis and clinical evolution. DNA ploidy is viewed as a marker of gross genomic aberrations. The aim of this study is to evaluate the DNA ploidy in the common subtypes of(More)
PURPOSE To report the feasibility and the safety of a surgeon-controlled robotic endoscope holder in laparoscopic surgery. PATIENTS AND METHODS From March 2010 to September 2010, 20 patients were enrolled prospectively to undergo a laparoscopic procedure using an innovative robotic endoscope holder. Two surgeons performed six adrenalectomies, four(More)
