Prostate, urology

Greater personalization of cancer medicine continues to shape therapy development and patient selection accordingly. The treatment of prostate cancer has evolved considerably since the discovery of androgen deprivation therapy. The comprehensive profiling of the prostate cancer genome has mapped the targetable molecular landscape of the disease and identified opportunities for the implementation of novel and combination therapies. In this review, we provide an overview of the molecular biology of prostate cancer and tools developed to aid prognostication and prediction of therapy benefit...

BACKGROUND AND OBJECTIVE: The European Association of Urology (EAU)-European Association of Nuclear Medicine (EANM)-European Society for Radiotherapy and Oncology (ESTRO)-European Society of Urogenital Radiology (ESUR)-International Society of Urological Pathology (ISUP)-International Society of Geriatric Oncology (SIOG) guidelines provide recommendations for the management of clinically localised prostate cancer (PCa). This paper aims to present a summary of the 2024 version of the EAU-EANM-ESTRO-ESUR-ISUP-SIOG guidelines on the screening, diagnosis, and treatment of clinically localised PCa...

Objective To construct a Convolutional Neural Network (CNN) model that can recognize and delineate anatomic structures on intraoperative video frames of robot-assisted radical prostatectomy (RARP) and to use these annotations to predict the surgical urethral length (SUL). Background Urethral dissection during RARP impacts patient urinary incontinence (UI) outcomes, and requires extensive training. Large differences exist between incontinence outcomes of different urologists and hospitals. Also, surgeon experience and education are critical towards optimal outcomes...

• Objective To prospectively assess early post-TUPS (transurethral prostate surgery) urinalysis changes and bacteriuria with its clinical relevance. • Methods Patients with BPO enrolled for TUPS were prospectively assessed. Patients were assessed at 2, 4, 8, 12, and 24-weeks postoperatively by DVAS (dysuria-visual-analogue-scale), IPSS-QOL, uroflow, and PVR. Routine urinalysis was performed before discharge and at all visits. MSUC (midstream urine culture) was performed before discharge, 4 and 12-weeks postoperatively...

INTRODUCTION: Natural Language Processing (NLP)-based data extraction from electronic health records (EHRs) holds significant potential to simplify clinical management and aid research. This review aims to evaluate the current landscape of NLP-based data extraction in prostate cancer (PCa) management. MATERIALS AND METHODS: We conducted a literature search of PubMed and Google Scholar databases using the keywords: "Natural Language Processing," "Prostate Cancer," "data extraction," and "EHR...

PURPOSE: Robot-assisted radical prostatectomy (RARP) is a common surgical procedure for the treatment of prostate cancer. Although beneficial, it can lead to intraoperative hypoxia due to high-pressure pneumoperitoneum and Trendelenburg position. This study explored the use of oxygen reserve index (ORi) to monitor and predict hypoxia during RARP. METHODS: A retrospective analysis was conducted on 329 patients who underwent RARP at the Seoul National University Bundang Hospital between July 2021 and March 2023...

BACKGROUND: Intraoperative complications (ICs) are invariably underreported in urological surgery despite the recent endorsement of new classification systems. We aimed to provide a detailed overview of ICs during Retzius-sparing robot-assisted radical prostatectomy (RS-RARP). METHODS: We prospectively collected data from 1891 patients who underwent RS-RARP at a single high-volume European center from January 2010 to December 2022. ICs were collected based on surgery reports and categorized according to the Intraoperative Adverse Incident Classification (EAUiaiC)...

OBJECTIVES: To evaluate the International Society of Urological Pathology (ISUP) 5-tier grade grouping (GG) system of prostate cancers as well as previously proposed optimizations. PATIENTS AND METHODS: The PROCURE biobank is a prospective cohort study of patients with localized prostate cancer who underwent radical prostatectomy in Quebec province between 2005 and 2013. Surgical specimens were graded by experienced genitourinary pathologists using 2019 ISUP criteria...

Enzalutamide is an oral androgen receptor signaling inhibitor utilized in the treatment of men with prostate cancer. It is a moderate inducer of the cytochrome P450 (CYP) enzymes CYP2C9 and CYP2C19, and a strong inducer of CYP3A4. It was also shown to be a mild inhibitor of the efflux transporter P-glycoprotein in patients with prostate cancer. Enzalutamide is primarily metabolized by CYP3A4 and CYP2C8. The risk of enzalutamide drug interactions arises primarily when it is coadministered with other drugs that interact with these CYPs, including CYP3A4...

BACKGROUND: Certain widely used pathological outcome prediction models that were developed in tertiary centers tend to overpredict outcomes in the community setting; thus, the Michigan Urological-Surgery Improvement Collaborative (MUSIC) model was developed in general urology practice to address this issue. Additionally, the development of these models involved a relatively small proportion of Black men, potentially compromising the accuracy of predictions in this patient group. We tested the validity of the MUSIC and three widely used nomograms to compare their overall and race-stratified predictive performance...

The Holmium:YAG laser has been the gold standard for laser lithotripsy over the past three decades and, since the late 1990s, also for prostate enucleation. Pulsed thulium fibre lasers (TFL) demonstrated their efficacy in in-vitro experiments and were introduced to the market a few years ago. Initial clinical results for TFL in lithotripsy and enucleation are very promising. In addition to TFL, a pulsed Thulium:YAG solid-state laser has been introduced, but clinical data for this laser are currently limited...

PURPOSE: Second malignancy is a rare but potentially lethal event after prostate brachytherapy, but data remain scarce on its long-term risk. The objective of this study is to estimate the number of pelvic second malignancies following brachytherapy compared to prostatectomy (RP). MATERIALS AND METHODS: Retrospective review of patients treated with low dose 125 I brachytherapy and prostatectomy in British Columbia from 1999 to 2010. Kaplan Meier (KM) estimates for pelvic (bladder and rectum), invasive pelvic, any second malignancy and death from any second malignancy were assessed...

OBJECTIVE: To explore the mediating effect of coping style between illness perception and fear of cancer recurrence in patients undergoing radical prostatectomy. METHODS: A questionnaire survey was carried out in 254 eligible patients who underwent radical prostatectomy in the urology department of two comprehensive tertiary hospitals in Wenzhou City from June 2022 to December 2022. The questionnaires include the general data questionnaire, brief illness perception questionnaire (BIPQ), Medical Coping Modes Questionnaire (MCMQ) and Fear of Progression Questionnaire-Short Form (FoP-Q-SF)...

OBJECTIVES: This study investigated the effects of prostate surgery on storage symptoms in male patients with lower urinary tract symptoms (LUTS) from benign prostatic enlargement (BPE). This study aimed to identify patient characteristics associated with improved, unchanged, and deteriorated post-surgical storage symptoms and to identify the risk factors for non-improvement or deterioration. METHODS: A retrospective analysis of 586 prostate surgeries performed between 2016 and 2022 at Yokosuka Kyosai Hospital was conducted on patients with LUTS and at least one storage symptom preoperatively...

OBJECTIVE: To assess the re-intervention rates of new surgical benign prostatic hyperplasia (BPH) interventions, as the clinical durability of new surgical interventions for BPH is not widely known. METHODS: A critical review of new surgical BPH therapies namely 'UroLift®', 'Aquablation', 'Rezum', 'prostatic artery embolisation (PAE)' and 'temporary implantable nitinol device (iTIND)' was performed on PubMed, the Cochrane Library, and Embase databases between May 2010 and December 2022 according to the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) statement...

BACKGROUND: While transurethral resection of the prostate (TURP) is the standard-of-care, Holmium laser enucleation of the prostate (HoLEP) is widely accepted as a size-independent method for surgical treatment of patients with lower urinary tract symptoms (LUTS) secondary to bladder outlet obstruction (BOO). However, in an ageing society an increasing number of patients presents with BOO due to locally advanced prostate cancer. There is currently no guidelines recommendation as to the enucleation or resection technique...

Polypharmacy exacerbates lower urinary tract symptoms (LUTS). Japan exhibits a higher prevalence of concomitant medication use in drug therapy than other countries. Previous age- and sex-specific reports exist; however, none include patients of all ages. Therefore, this retrospective study determined the impact of polypharmacy and its associated risk factors on LUTS exacerbation in outpatients with urological conditions. We included patients receiving medication who visited the Department of Urology at the Gifu Municipal Hospital (Gifu, Japan) between January, 2018 and December, 2018...

OBJECTIVES:  We conducted a focus group to assess the attitudes of primary care physicians (PCPs) toward prostate-specific antigen (PSA)-screening algorithms, perceptions of using decision support tools, and features that would make such tools feasible to implement. METHODS:  A multidisciplinary team (primary care, urology, behavioral sciences, bioinformatics) developed the decision support tool that was presented to a focus group of 10 PCPs who also filled out a survey...
