: The use of non-invasive techniques to predict the histological type of renal masses can avoid a renal mass biopsy, thus being of great clinical interest. The aim of our study was to assess if quantitative multiphasic multidetector computed tomography (MDCT) enhancement patterns of renal masses (malignant and benign) may be useful to enable lesion differentiation by their enhancement characteristics. : A total of 154 renal tumors were retrospectively analyzed with a four-phase MDCT protocol. We studied attenuation values using the values within the most avidly enhancing portion of the tumor (2D analysis) and within the whole tumor volume (3D analysis). A region of interest (ROI) was also placed in the adjacent uninvolved renal cortex to calculate the relative tumor enhancement ratio. : Significant differences were noted in enhancement and de-enhancement (diminution of attenuation measurements between the postcontrast phases) values by histology. The highest areas under the receiver operating characteristic curves (AUCs) of 0.976 (95% CI: 0.924-0.995) and 0.827 (95% CI: 0.752-0.887), respectively, were demonstrated between clear cell renal cell carcinoma (ccRCC) and papillary RCC (pRCC)/oncocytoma. The 3D analysis allowed the differentiation of ccRCC from chromophobe RCC (chrRCC) with a AUC of 0.643 (95% CI: 0.555-0.724). Wash-out values proved useful only for discrimination between ccRCC and oncocytoma (43.34 vs 64.10, < 0.001). However, the relative tumor enhancement ratio (corticomedullary (CM) and nephrographic phases) proved useful for discrimination between ccRCC, pRCC, and chrRCC, with the values from the CM phase having higher AUCs of 0.973 (95% CI: 0.929-0.993) and 0.799 (95% CI: 0.721-0.864), respectively. : Our observations point out that imaging features may contribute to providing prognostic information helpful in the management strategy of renal masses.

A 54-year-old man who had been on the kidney donor register for 32 years received a kidney from a 9-year-old boy who had died of fulminant myocarditis. The post-operative course was poor, and hemodialysis was still needed after surgery. A kidney biopsy one hour after surgery showed a neutrophil-predominant inflammatory cell infiltrate localized to the peritubular capillaries (PTC) and acute tubular necrosis of the proximal tubule.

Objectives: To evaluate the at-risk organs that require protection during percutaneous cryoablation (PCA) of renal tumours and the correlation with patient and target lesion characteristics, type of protective measure used and postoperative outcomes.
Materials And Methods: Single-centre retrospective review of patients with renal tumours who underwent PCA between 2008 and 2020. Final analysis included 374 tumours.

Background: Bilateral synchronous renal masses (BSRMs) are a rare finding, and the optimal treatment strategy remains undetermined. This study depicts the management of BSRM at eight European high-volume centers.
Methods: This is a retrospective analysis of prospective institutional databases collecting all patients presenting with clinical T1-2 N0 M0 BSRMs between 1993 and 2020 at 8 tertiary referral high-volume centers for renal cancer treatment in Europe.

Renal cell carcinoma (RCC) is one of the most common malignancies in the urinary system, and clear cell renal cell carcinoma (ccRCC) is the most common subtype. MYBL2 has been reported to be overexpressed in various tumors and associated with poor prognosis in patients, but its biological role in ccRCC remains unclear. In this study, we investigated the mRNA and protein expression levels of MYBL2 in ccRCC samples and evaluated the prognostic value of MYBL2 using TCGA dataset.
