The efficacy of the new Bosniak classification v.2019 in benign lesions prediction within the higher Bosniak cysts classes.

Introduction: Identification of benign lesions among higher classes of renal Bosniak cysts who are vulnerable to active surveillance instead of surgical approach is still questionable. We aimed in this study to delineate the efficacy of the new Bosniak v2019 classification in benign lesions identification among those cases with higher Bosniak classes in comparison with the final histopathology.

Materials: In a retrospective review between 2010 and 2021 for patients diagnosed as higher classes Bosniak renal masses was done.

Role of AI and Radiomic Markers in Early Diagnosis of Renal Cancer and Clinical Outcome Prediction: A Brief Review.

Globally, renal cancer (RC) is the 10th most common cancer among men and women. The new era of artificial intelligence (AI) and radiomics have allowed the development of AI-based computer-aided diagnostic/prediction (AI-based CAD/CAP) systems, which have shown promise for the diagnosis of RC (i.e.

Objectives: To report the incidence, predictors, the impact of bladder perforation (BP), and our protocol of management in patients who underwent trans-urethral resection of bladder tumor (TURBT).

Methods: This is a retrospective study, between 2006 and 2020, on patients who underwent TURBT for non-muscle-invasive bladder cancer (NMIBC). Bladder perforation was defined as any full thickness resection of the bladder wall.

Role of multiparametric magnetic resonance imaging in the diagnosis and staging of urinary bladder cancer.

Objectives: To assess the role of multiparametric magnetic resonance imaging (mp-MRI) in the diagnosis and staging of urinary bladder cancer (BC).

Materials And Methods: Fifty patients diagnosed with bladder masses underwent mp-MRI study. The results of 3 image sets were analyzed and compared with the histopathological results as a reference standard: T2-weighted image (T2WI) plus dynamic contrast-enhanced (DCE), T2WI plus diffusion-weighted images (DWI), and mp-MRI, including T2WI plus DWI and DCE.

The sequence of intervention determines the risk of early postoperative acute kidney injury in infants with bilateral ureteropelvic junction obstruction.

Introduction And Objectives: The management of bilateral ureteropelvic junction obstruction (UPJO) is greatly debated. We aim to identify the risk of early postoperative acute kidney injury (AKI) in relation to the sequence of intervention in children with bilateral UPJO managed in a sequential manner.

Methods: A single center database was retrospectively reviewed for children ≤2 years who underwent bilateral pyeloplasty.

Bosniak classification version 2019: a prospective comparison of CT and MRI.

Objective: To assess the diagnostic accuracy and agreement of CT and MRI in terms of the Bosniak classification version 2019 (BCv2019).

Materials And Methods: A prospective multi-institutional study enrolled 63 patients with 67 complicated cystic renal masses (CRMs) discovered during ultrasound examination. All patients underwent CT and MRI scans and histopathology.

One-stage versus staged ureteroscopy and percutaneous nephrolithotomy for simultaneous ureteral and renal stones.

Objectives: This study is aimed to investigate the outcome of one-stage ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) for simultaneous ureteral and renal stones over 10years at a tertiary urology institute.

Materials And Methods: We retrospectively analyzed the data of patients who were operated on for simultaneous ureteral and renal stones from January 2011 to December 2020. Patients were divided into 2 groups: group A, who underwent one-stage URS and prone PCNL, and group B, who underwent staged procedures.

Optimization of shockwave lithotripsy use for single medium sized hard renal stone with stone density ≥ 1000 HU. A prospective study.

Purpose: To identify shock wave lithotripsy (SWL) success predictors in hard renal stones (average stone density ≥ 1000 HU).

Materials: We prospectively evaluated patients who underwent SWL for hard renal stones between April 2018 and December 2020. Radiological parameters were identified, e.

A Comprehensive Computer-Assisted Diagnosis System for Early Assessment of Renal Cancer Tumors.

Renal cell carcinoma (RCC) is the most common and a highly aggressive type of malignant renal tumor. In this manuscript, we aim to identify and integrate the optimal discriminating morphological, textural, and functional features that best describe the malignancy status of a given renal tumor. The integrated discriminating features may lead to the development of a novel comprehensive renal cancer computer-assisted diagnosis (RC-CAD) system with the ability to discriminate between benign and malignant renal tumors and specify the malignancy subtypes for optimal medical management.

Imaging of Bladder Cancer: Standard Applications and Future Trends.

The evolution in imaging has had an increasing role in the diagnosis, staging and follow up of bladder cancer. Conventional cystoscopy is crucial in the diagnosis of bladder cancer. However, a cystoscopic procedure cannot always depict carcinoma in situ (CIS) or differentiate benign from malignant tumors prior to biopsy.
