Background The aim of the study is to compare the diagnostic value of models that based on a set of CT texture and non-texture features for differentiating clear cell renal cell carcinomas(ccRCCs) from non-clear cell renal cell carcinomas(non-ccRCCs). Methods A total of 197 pathologically proven renal tumors were divided into ccRCC(n = 143) and non-ccRCC (n = 54) groups. The 43 non-texture features and 296 texture features that extracted from the 3D volume tumor tissue were assessed for each tumor at both Non-contrast Phase, NCP; Corticomedullary Phase, CMP; Nephrographic Phase, NP and Excretory Phase, EP. Texture-score were calculated by the Least Absolute Shrinkage and Selection Operator (LASSO) to screen the most valuable texture features. Model 1 contains the three most distinctive non-texture features with p < 0.001, Model 2 contains texture scores, and Model 3 contains the above two types of features. Results The three models shown good discrimination of the ccRCC from non-ccRCC in NCP, CMP, NP, and EP. The area under receiver operating characteristic curve (AUC)values of the Model 1, Model 2, and Model 3 in differentiating the two groups were 0.748–0.823, 0.776–0.887 and 0.864–0.900, respectively. The difference in AUC between every two of the three Models was statistically significant (p < 0.001). Conclusions The predictive efficacy of ccRCC was significantly improved by combining non-texture features and texture features to construct a combined diagnostic model, which could provide a reliable basis for clinical treatment options.

“…Banno and collegues from Japan ( 4 ) present on page 26 an interesting study about computed tomography imaging characteristics of clear cell papillary renal cell carcinoma (CCP), a new subtype of Renal cell carcinoma (RCC) recognized in 2013. The authors studied 12 patients pathologically diagnosed with CCP RCC and concluded that the CT imaging characteristics of CCP RCCs could be categorized into either solid or cystic type.…”

since 1995 and started to work at the Int Braz J Urol in 1999 as a reviewer, invited by Professor Francisco J. B. Sampaio. During this time I have learned a lot from the latest editors and could witness the growth of our journal. Today, the journal is well established and can be considered one of the most respected journals in the urological community. For the first time, there was a contest for the choice of the editor of the Journal, where the candidates were evaluated by a select examining board composed of five teachers, including the last two editors of the Journal (Drs. Francisco Sampaio and Sidney Glina). With great honor I was chosen as the next editor for the next 4 years with a possibility of renewal. Currently, the Int Braz J Urol is well structured and has an impact of 1,046 on the JCR. Our main goal will be to achieve an increased impact. For this, we have implemented some changes: 1) Only articles submitted in the English language will be accepted; 2) We will end the section of clinical cases, 3) We will be extremely rigorous with the time of review of articles, 4) We will value ad-hoc reviewers and greatly increase the level of demand for articles to be accepted, 5) We will create two new sections: a) update in urology, where experts will comment on the main articles published in their sub-specialty in other journals and b) Expert opinion, where experts will make mini reviewes about your area; in this number Dr. Sandro Esteves made a very interesting review about infertiligy (1). With these changes we hope that by the end of our term in 2024 Int Braz J Urol will have an impact commensurate with its importance. This first number of Int Braz J Urol under my supervision presents original contributions with a lot of interesting papers in different fields: Prostate Cancer, Renal Stones, Renal Cell Carcinoma,

Clear cell papillary renal cell carcinoma (CCPRCC) is a newly classified renal cell carcinoma with a low degree of malignancy. Its imaging features have not been studied deeply. Therefore, we reviewed the imaging features of CCPRCC. Solid CCPRCC shows high echo or isoecho mass on conventional ultrasound. Contrast enhanced ultrasound shows “fast forward and slow backward, uneven high enhancement”. Computed tomography shows high enhancement and maximum enhancement in the cortical‐medullary phase. Magnetic resonance imaging shows slightly low T1WI and high T2WI. This article aims to improve the understanding of CCPRCC by clinical radiologists and promote the accurate.
