CONTEXT AND OBJECTIVES The European Association of Urology Guideline Group for renal cell carcinoma (RCC) has prepared these guidelines to help clinicians assess the current evidence-based management of RCC and to incorporate the present recommendations into daily clinical practice. EVIDENCE ACQUISITION The recommendations provided in the current updated(More)
CONTEXT The European Association of Urology Guideline Panel for Renal Cell Carcinoma (RCC) has prepared evidence-based guidelines and recommendations for RCC management. OBJECTIVES To provide an update of the 2010 RCC guideline based on a standardised methodology that is robust, transparent, reproducible, and reliable. EVIDENCE ACQUISITION For the 2014(More)
CONTEXT The role of percutaneous renal tumour biopsy (RTB) remains controversial due to uncertainties regarding its diagnostic accuracy and safety. OBJECTIVE We performed a systematic review and meta-analysis to determine the safety and accuracy of percutaneous RTB for the diagnosis of malignancy, histologic tumour subtype, and grade. EVIDENCE(More)
Papillary renal cell carcinoma (RCC) is subclassified in type 1 displaying cells with scanty pale cytoplasm arranged in a single layer and in type 2 showing pseudostratified cells with eosinophilic cytoplasm. However, the existence of more variants of papillary RCC may be inferred by the recognition of few cases with different morphological features. We(More)
Tubulocystic renal carcinoma (TCRC) is a recently described neoplastic entity. To date, clinicopathological features on less than hundred cases of these rare tumours have been characterized exclusively in the pathological literature. Herein, we present five additional cases emphasizing clinical aspects on these rare renal neoplasms. Cases diagnosed as TCRC(More)
Hybrid oncocytic/chromophobe tumors (HOCT) of the kidney have been described in patients with Birt–Hogg–Dubé syndrome (BHD) and in association with renal oncocytosis without BHD. HOCT in patients without evidence of BHD or renal oncocytosis is exceedingly rare, and these cases have been poorly characterized. We have identified and studied 14 cases of HOCT(More)
BACKGROUND MicroRNAs (miRNAs), which are endogenously expressed regulatory noncoding RNAs, have an altered expression in tumor tissues. MiRNAs regulate cancer-related processes such as cell growth and tissue differentiation, and therefore, might function as oncogenes or tumor-suppressor genes. The aim of our study was to assess the expression of mir-20a,(More)
Sir, we report three cases of conventional renal cell carcinomas (CRCC) with granulomatous reaction occurring in the tumorous stroma. The patients were two women and one man aged from 73 years to 85 years (mean 78.3 years). All patients were treated only by nephrectomy. Tumours were well circumscribed, yellow to tan coloured with haemorrhagic foci. The size(More)
OBJECTIVES To assess the feasibility of partial nephrectomy (PN) without renal hilar clamping using the 80-W GreenLight (532 nm) laser with opening of the collecting system followed by its suture in a porcine model. METHODS We performed 12 open laser PNs in 6 farm pigs. We used the technique of incisional laser ablation of the lower pole of the right(More)
AIMS We present the largest series of an unclassified subtype of renal cell carcinoma, which seems to be a distinct morphological entity and which is sometimes designated as spindle and cuboidal renal cell carcinoma. METHODS AND RESULTS Eleven cases of spindle and cuboidal renal cell carcinoma were found among 7000 primary renal cell tumours in Pilsen's(More)
