Abstract Objectives: This study aimed to develop an artificial intelligence (AI)-based image recognition system using the nnU-Net adaptive neural network to assist clinicians in detecting magnetic resonance imaging (MRI)-invisible prostate cancer. The motivation stems from the diagnostic challenges, especially when MRI findings are inconclusive (Prostate Imaging Reporting and Data System [PI-RADS] score ≤ 3). Methods: We retrospectively included 150 patients who underwent systematic prostate biopsy at Beijing Friendship Hospital between January 2013 and January 2023. All were pathologically confirmed to have clinically significant prostate cancer, despite negative findings on preoperative MRI. A total of 1475 MRI… More >

Abstract Background: Radiogenomics offers a non-invasive approach to correlate imaging features with tumor molecular profiles. This study aims to identify computed tomography (CT) imaging characteristics associated with positive NIPA-like domain containing 4 (NIPAL4) expression in clear cell renal cell carcinoma (ccRCC) and to develop a radiogenomic predictive model to support personalized risk stratification. Methods: A retrospective analysis was conducted on 241 ccRCC patients from The Cancer Genome Atlas (TCGA) and The Cancer Imaging Archive (TCIA) databases. Clinical, pathological, and CT features were compared between NIPAL4-positive and NIPAL4-negative groups. A penalized logistic regression model was built to… More >

Abstract Background: Aquablation is a robotic-assisted, water jet-based transurethral therapy for benign prostatic hyperplasia (BPH). Concerns about postoperative hematuria led to the practice of limited transurethral resection (TUR) with cauterization. This study aimed to assess the impact of tranexamic acid (TXA) on hematuria outcomes when combined with limited TUR after Aquablation. Methods: We retrospectively analyzed men undergoing Aquablation at our institution (October 2020–July 2024). Demographic, prostate, surgical, and hematuria outcomes were extracted from electronic medical records. Kruskal-Wallis test compared medians. Results: Of 131 patients, 113 (86%) had limited TUR; 31 (27%) received 1 g TXA perioperatively. TXA… More >

Abstract Late-onset hypogonadism (LOH), characterized by the intersection of aging and androgen deficiency, impacts the health of approximately 2%−39% of middle-aged and elderly men, underscoring the need for comprehensive research. Animal models, serving as analogs of human diseases, are indispensable for investigating disease mechanisms and facilitating drug development. However, the diverse array of animal models utilized for LOH research has led to a lack of standardized modeling approaches and evaluation systems, potentially impeding progress in understanding the pathogenesis and therapeutic development. In this paper, we summarize and compile the characteristics, methods, and evaluation systems of rodent More >

Abstract Background: Spontaneous rupture of the urinary bladder (SRUB) is a rare condition characterized by bladder rupture without any trauma or previous instrumentation. Diagnosing SRUB can be challenging, leading to potential delays in treatment and significant morbidity. Case description: We present a case of a 75-year-old male with a complex medical history, including atrial fibrillation, systemic lupus erythematosus, antiphospholipid syndrome, and chronic anticoagulation, who developed sudden onset gross hematuria and abdominal pain following bilateral internal iliac artery angioembolization for a spontaneous pelvic hematoma in the setting of supratherapeutic anticoagulation. Extraperitoneal bladder perforation was confirmed by CT cystogram.… More >

Abstract Overview: Freehand transperineal prostate biopsy (TPPB) needle guides are designed to maintain a parallel alignment between the co-axial introducer needle and the ultrasound (US) transducer. However, this parallel alignment necessitates transducer angulations within the patient’s rectum for sampling anterior or posterior regions of the prostate, which introduces several problems both for the patient and the operator. This article introduces a technique using a TPPB needle guide system with a novel angle-adjustment feature, which minimizes intrarectal transducer movements. Objectives: Freehand TPPB typically requires anterior or posterior angulation of the ultrasound (US) transducer, which leads to prostate More >

Abstract Background: Studies have indicated an association between inflammatory factors (IFs) in the blood and the development of bladder cancer (BC). This study aimed to explore the correlation and clinical significance of IFs with the pathological grading of BC. Methods: A retrospective analysis was conducted on the preoperative blood routine results, postoperative pathological findings, and baseline information of 163 patients. Patients were divided into high-grade and low-grade groups based on pathological grading. Group comparisons and logistic regression analyses were performed using R software version 4.1.3 to explore the relationships between IFs and BC pathological grading. Results: The… More >
