Artificial Intelligence in Urologic Robotic Oncologic Surgery: A Narrative Review.

With the rapid increase in computer processing capacity over the past two decades, machine learning techniques have been applied in many sectors of daily life. Machine learning in therapeutic settings is also gaining popularity. We analysed current studies on machine learning in robotic urologic surgery. We searched PubMed/Medline and Google Scholar up to December 2023. Search terms included "urologic surgery", "artificial intelligence", "machine learning", "neural network", "automation", and "robotic surgery". Automatic preoperative imaging, intraoperative anatomy matching, and bleeding prediction has been a major focus. Early artificial intelligence (AI) therapeutic outcomes are promising. Robot-assisted surgery provides precise telemetry data and a cutting-edge viewing console to analyse and improve AI integration in surgery. Machine learning enhances surgical skill feedback, procedure effectiveness, surgical guidance, and postoperative prediction. Tension-sensors on robotic arms and augmented reality can improve surgery. This provides real-time organ motion monitoring, improving precision and accuracy. As datasets develop and electronic health records are used more and more, these technologies will become more effective and useful. AI in robotic surgery is intended to improve surgical training and experience. Both seek precision to improve surgical care. AI in ''master-slave'' robotic surgery offers the detailed, step-by-step examination of autonomous robotic treatments.

Ureteral stent related symptoms: A comparative study.

BACKGROUND: In urology, ureteral stents are used to treat obstructive diseases. Hematuria (54%), fever, discomfort, and lower urinary system symptoms are the predominant symptoms related to ureteral stent. AIM: This article links stent symptoms to double-j width and length, as well as patient's height, weight, and body mass index (BMI). Ureteric Stent Symptoms Questionnaire (USSQ) was used to measure ureteral stent symptoms at 1st and 4th week of stent in situ as well as the 4th week after pigtail removal. METHODS: A 200-patient prospective study, where patients were allocated into four groups following ureteral stent insertion depending on the stent characteristics. Those groups were: 4.8 Fr./26 cm (Group A), 4.8 Fr./28 cm (Group B), 6 Fr/26 cm (Group C), and 6 Fr/28 cm (Group D). RESULTS: Men comprised 53.5% of 200 patients. Participants had an average age of 49 ± 15.5 years, height of 175 ± 8.94 cm, and BMI of 23.8 ± 7.6 cm. The laboratory results were identical between groups. At the first and fourth week, groups had similar urine symptoms, pain severity, health status and occupational activities. The difference in pain location was statistically significant. Group A had 82.4% renal back pain in the first week, whereas Group B had 68.8%, Group C 31.3% and Group D 62.5 (p=0.04). At the fourth week, 64.7% of Group A patients reported kidney front pain, compared to 100% of Group B, 93.3% of Group C, and 100% of Group D (p=0.04). There was statistical significance in the sexual activity of the patients. 24.4% of Group C patients stopped sexual activity before stent installation, compared to 10.6%, 8.3%, and 6.4% of the other groups (p=0.03). A moderate percentage of patients had active sexual activity at week 4 (Group A: 7.8%, Group B: 5.8%, Group C: 8.2%, Group D: 4.1%), p=0.83. In multivariate analysis, urinary catheter group, age, weight, height, and BMI did not significantly affect urine index score (UIS), pain index score (PIS), general health (GH), quality of work (QW), and quality of sex (QS). CONCLUSIONS: Despite various attempts to establish the best ureteral stent, the effect of double-j stent physical features on stent-related symptoms remained unknown. No verdict is conceivable without adequate empirical data.

Emerging Trends in AI and Radiomics for Bladder, Kidney, and Prostate Cancer: A Critical Review.

This comprehensive review critically examines the transformative impact of artificial intelligence (AI) and radiomics in the diagnosis, prognosis, and management of bladder, kidney, and prostate cancers. These cutting-edge technologies are revolutionizing the landscape of cancer care, enhancing both precision and personalization in medical treatments. Our review provides an in-depth analysis of the latest advancements in AI and radiomics, with a specific focus on their roles in urological oncology. We discuss how AI and radiomics have notably improved the accuracy of diagnosis and staging in bladder cancer, especially through advanced imaging techniques like multiparametric MRI (mpMRI) and CT scans. These tools are pivotal in assessing muscle invasiveness and pathological grades, critical elements in formulating treatment plans. In the realm of kidney cancer, AI and radiomics aid in distinguishing between renal cell carcinoma (RCC) subtypes and grades. The integration of radiogenomics offers a comprehensive view of disease biology, leading to tailored therapeutic approaches. Prostate cancer diagnosis and management have also seen substantial benefits from these technologies. AI-enhanced MRI has significantly improved tumor detection and localization, thereby aiding in more effective treatment planning. The review also addresses the challenges in integrating AI and radiomics into clinical practice, such as the need for standardization, ensuring data quality, and overcoming the "black box" nature of AI. We emphasize the importance of multicentric collaborations and extensive studies to enhance the applicability and generalizability of these technologies in diverse clinical settings. In conclusion, AI and radiomics represent a major paradigm shift in oncology, offering more precise, personalized, and patient-centric approaches to cancer care. While their potential to improve diagnostic accuracy, patient outcomes, and our understanding of cancer biology is profound, challenges in clinical integration and application persist. We advocate for continued research and development in AI and radiomics, underscoring the need to address existing limitations to fully leverage their capabilities in the field of oncology.

Ureteral stents: A brief narrative review of the different polymeric types, their characteristics, and their connection to stent-related symptoms.

Background: In routine urological practice, pigtails are frequently utilized to relieve blockage. Early signs of pigtail problems include pain, lower urinary tract symptoms, pain, hematuria (54%) and fever. Seventy percent of patients experience irritable voiding symptoms, and 80% of patients or even more report pain interfering with everyday activities. Methods: This article's goal is to evaluate the various polymeric stents that are currently on the market. In addition, a review of their fundamental bioqualities is conducted, and a connection between their physical attributes (length, size, and composition) and stent-related issues is looked into. For this review, extensive Medline, PubMed, and literature research from 1987 to January 2023 was conducted. Lower urinary tract complaints, ureteral stents, "pigtail," "materials," "characteristics," or "properties" were the search terms employed. Results: The reviews and publications that are now accessible linking certain materials to stent-related symptoms offer contradictory conclusions, and the majority of research do not specify the precise properties of the materials utilized. The results of the studies on the relationship between stents length and diameter and symptoms connected to stents are likewise inconclusive, despite the fact that there are several studies on this topic in the literature. Conclusion: Numerous studies imply a connection between the various types and properties of the utilized stents and stent-related complaints. However, the available data did not fully support this claim, necessitating additional research.

Surgical techniques to preserve continence after robot-assisted radical prostatectomy.

Radical prostatectomy significantly impacts the inherent anatomy of the male pelvis and the functional mechanisms of urinary continence. Incontinence has a considerable negative influence on the quality of life of patients, as well as their social and psychological wellbeing. Numerous surgical techniques have been demonstrated to support the preservation of continence during robot-assisted radical prostatectomy (RARP). In this in-depth analysis, we give a general summary of the surgical techniques used in RARP and their impact on incontinence rates.

Radiation protection measures during endourological therapies.

Objective: The objective of this narrative review was to search the existing literature for studies reporting measures to minimize radiation use during endoscopic management of stone disease and present ways of reducing the exposure of both patients and operating room staff. Methods: A literature review in PubMed was performed to identify studies describing protocols or measures to reduce radiation received during endourological procedures from January 1970 to August 2022. Eligible studies were those that reported outcomes for ureteroscopy or percutaneous nephrolithotripsy regarding measures to minimize radiation doses used intraoperatively, performed either in real-life theatres or using phantoms. Both comparative and non-comparative studies were deemed eligible. Results: Protection can be achieved initially at the level of diagnosis and follow-up of patients, which should be done following an algorithm and choice of more conservative imaging methods. Certain protocols, which follow principles for minimized fluoroscopy use should be implemented and urologists as well as operating room staff should be continuously trained regarding radiation damage and protection measures. Wearing protective lead equipment remains a cornerstone for personnel protection, while configuration of the operating room and adjusting X-ray machine settings can also significantly reduce radiation energy. Conclusion: There are specific measures, which can be implemented to reduce radiation exposure. These include avoiding excessive use of computed tomography scans and X-rays during diagnosis and follow-up of urolithiasis patients. Intraoperative protocols with minimal fluoroscopy use can be employed. Staff training regarding dangers of radiation plays also a major role. Use and maintenance of protective equipment and setting up the operating room properly also serve towards this goal. Machine settings can be customized appropriately and finally continuously monitoring of exposure with dosimeters can be adopted.

Ureteral Stent-Related Symptoms and Pharmacotherapy: A Brief Narrative Review.

The purpose of this article is to review the effects of different types of pharmacotherapy on symptoms that affect the quality of a patient's life after stent insertion. A thorough Medline/PubMed nonsystematic review was conducted from 1987 to January 2023, using the terms: "pigtail" OR "ureteral stents" AND "lower urinary tracts symptoms" OR "LUTS" AND "pharmacotherapy" OR "drugs". Relevant studies conducted in humans and reported in English language were included. The available reviews and articles associating the use of drugs with stent-related symptoms (SRS) provide conflicting results. Most of them show a clear benefit of alpha blockers, particularly alfuzosin, on treating urinary SRS, and hence there is a strong recommendation for the use of alpha blockers for the treatment of SRS in the guidelines of the European Association of Urology. Anticholinergics and mirabegron have shown a significant benefit in dealing with irritative bladder symptoms. In contrast, the findings for combination therapies are contradictory, with some studies showing that combination therapy is no superior to monotherapy with regards to most of the subsets of the Ureteral Stent Symptom Questionnaire (USSQ), whereas others present a clear benefit of combination therapies, specifically silodosin and solifenacin, in treating stent-associated lower urinary tract symptoms (LUTS), in comparison with any other type of monotherapy or combination therapy. Many studies suggest that some categories of pharmacotherapy, such as alpha blockers, can alleviate SRS. However, there is conflicting evidence concerning most other types of medical treatment. Randomized trials with the largest number of patients are needed to investigate the effectiveness of novel approaches on SRS.

Acceptance of Artificial Intelligence in Supporting Cancer Patients.

ASCAPE Project is a study aiming to implement the advances of Artificial Intelligence (AI), to support prostate cancer survivors, regarding quality of life issues. The aim of the study is to determine characteristics of patients who accepted to join ASCAPE project. It results that participants of the study mainly originate from higher-educated societies that are better informed about the potential benefits of AI in medicine. Therefore, efforts should be focused on eliminating patients' reluctancy by better informing them on the potential benefits of AI.

Training ChatGPT Models in Assisting Urologists in Daily Practice.

Artificial Intelligence (AI) has shown the ability to enhance the accuracy and efficiency of physicians. ChatGPT is an AI chatbot that can interact with humans through text, over the internet. It is trained with machine learning algorithms, using large datasets. In this study, we compare the performance of using a ChatGPT API 3.5 Turbo model to a general model, in assisting urologists in obtaining accurate, valid medical information. The API was accessed through a Python script that was applied specifically for this study based on 2023 EAU guidelines in PDF format. This custom-trained model leads to providing doctors with more precise, prompt answers about specific urologic subjects, thus helping them, ultimately, providing better patient care.

Anthropometric characteristics and relationship with non-muscle invasive bladder cancer in Greece: A case-control study.

BACKGROUND: Risk factors like smoking, radiation, chronic infections and exposure to occupational chemicals are strongly associated with occurrence of bladder cancer. Association between increased body weight and bladder cancer has been controversial. The aim of this case-control study is to evaluate association of anthropometric characteristics on bladder cancer incidence in Greek population. METHODS: This case-control study was conducted at a tertiary hospital in Greece with cases being patients with bladder cancer diagnosed within the last 2 years and controls patients admitted to hospital for reason other than cancer and not related to common risk factors related to bladder cancer. Anthropometric characteristics like weight, height, body mass index, waist and hip circumference were measured. Analyses was done with R (Vienna, Austria). RESULTS: Comparison between groups showed that patients with bladder cancer had higher weight, BMI and waist circumference compared to controls. However, multivariate, binomial logistic regression showed that only age (OR 1.03, 95% CI: 1-1.05, p = 0.02), no use of smoke (OR 0.12, 95% CI: 0.07-0.23, p < 0.001) and occupation related to bladder cancer (OR 7.45, 95% CI: 2.53-27.93, p < 0.001) significantly predicted the incidence of bladder cancer. CONCLUSIONS: Bladder cancer incidence is strongly linked with specific risk factors such as smoking, occupation with exposure to chemicals and smoke, increasing age, radiation and chronic infections. Several studies have shown a weak association between anthropometric characteristics and bladder cancer, although most studies in European populations did not confirm these findings. Similarly in our case-control study in a Greek population, we found potential relationship between increased weight/BMI and waist circumference with bladder cancer, but the association disappeared in multivariate analysis.

Post Radical Prostatectomy Erectile Dysfunction. A Single Centre Experience.

INTRODUCTION: This study aims to determine the effects of radical retropubic prostatectomy on post-operative erectile function. MATERIALS & METHODS: A total of 50 patients were included in this study, diagnosed with localized prostate cancer, and underwent nerve-sparing radical retropubic prostatectomy. All patients completed the International Index of Erectile Function (IIEF-5) questionnaire pre-operatively and on the third, sixth, and twelfth post-operative month and completed a self-reporting of their satisfaction with their sexual performance. Patients with a history of severe heart disease, were on erectile dysfunction medication, or had a score of 7 or less on the IIEF-5 questionnaire, were excluded from the study. RESULTS: Pre-operatively it was observed that the lower the IIEF-5 score, the higher the biopsy Gleason score. Post-operatively, 16 patients stated that erectile function had returned to the pre-operative IIEF-5 category. In contrast, only 13 of them stated they were happy with their sexual performance on the self-reporting scale. The rest reported dissatisfaction despite returning to their pre-operative erectile function status. IIEF-5 scores were also different when compared amongst the four age groups, with scores indicating that younger age is related to higher IIEF-5 scores. At the 3-month follow-up, no statistically significant difference was observed between age groups. Finally, patients younger than 64 reported significantly less deterioration in post-operative erectile function. CONCLUSION: Post-radical prostatectomy erectile dysfunction remains one of the most pressing issues in prostate cancer therapy. A higher Gleason score has a more significant impact on pre-operative ED, and at the same time, the best post-operative ED results are observed in younger patients. Finally, patients need extensive follow-up, therapy, and pre-and post-operative psychological support to have the best possible erectile function.

CT of the urinary tract revisited.

Computed tomography (CT) of the abdomen is usually appropriate for the initial imaging of many urinary tract diseases, due to its wide availability, fast scanning and acquisition of thin slices and isotropic data, that allow the creation of multiplanar reformatted and three-dimensional reconstructed images of excellent anatomic details. Non-enhanced CT remains the standard imaging modality for assessing renal colic. The technique allows the detection of nearly all types of urinary calculi and the estimation of stone burden. CT is the primary diagnostic tool for the characterization of an indeterminate renal mass, including both cystic and solid tumors. It is also the modality of choice for staging a primary renal tumor. Urolithiasis and urinary tract malignancies represent the main urogenic causes of hematuria. CT urography (CTU) improves the visualization of both the upper and lower urinary tract and is recommended for the investigation of gross hematuria and microscopic hematuria, in patients with predisposing factors for urologic malignancies. CTU is highly accurate in the detection and staging of upper tract urothelial malignancies. CT represents the most commonly used technique for the detection and staging of bladder carcinoma and the diagnostic efficacy of CT staging improves with more advanced disease. Nevertheless, it has limited accuracy in differentiating non-muscle invasive bladder carcinoma from muscle-invasive bladder carcinoma. In this review, clinical indications and the optimal imaging technique for CT of the urinary tract is reviewed. The CT features of common urologic diseases, including ureterolithiasis, renal tumors and urothelial carcinomas are discussed.

Outcomes from treatment of metastatic renal-cell carcinoma following failure of first-line anti-VEGF/VEGFR therapy: real-life evidence on the change of the treatment paradigm.

Recently approved agents for post-vascular endothelial growth factor/post-vascular endothelial growth factor receptor (VEGF/VEGFR) inhibitors treatment of metastatic renal-cell carcinomas (mRCC), such as axitinib, nivolumab, and cabozantinib were shown to improve prognosis and substituted everolimus in this setting. We studied practice patterns, efficacy, and tolerability of these agents in a real-world series of Greek patients. We included patients with mRCC who received everolimus, axitinib, or nivolumab after progression on first-line anti-VEGF/VEGFRs therapy. Patients were stratified into three groups. Group A received nivolumab with or without cabozantinib at some point in their disease. Group B received axitinib but without nivolumab or cabozantinib. Group C received only everolimus among the four approved agents. Overall, 131 patients were included in the analysis. Everolimus and nivolumab were mainly used in the second line, while axitinib and cabozantinib were mostly used in the third and fourth lines. Median overall survival (OS) from first-line initiation was 8.7 [95% confidence interval (CI), 4-not reached], 3.6 (95% CI, 2-6), and 2.1 years (95% CI, 1.4-2.6) for Group A, B, and C, respectively ( P < 0.001). Median OS from the initiation of second-line therapy was 3.5, 2.7, and 1.3 years, respectively ( P < 0.001). There was no impact of first-line agent or treatment timing on survival. International Metastatic Renal Cell Carcinoma Database Consortium risk stratification was associated with OS. Toxicities observed were within expected frequencies. Grade ≥3 events were rare. Adoption of modern standards in everyday treatment of mRCC results in prolongation of survival. Real-world datasets are the new landmarks of survival for future research.

The effects of method of anaesthesia on the safety and effectiveness of Radical Retropubic Prostatectomy.

OBJECTIVE: The aim of this study is to determine if patients undergoing radical retropubic prostatectomy with localized prostate cancer under combined (epidural-spinal) anaesthesia have any benefit over patients undergoing the procedure under general anaesthesia. MATERIAL AND METHODS: Patients with clinically localised prostate cancer, scheduled for radical retropubic prostatectomy, were allocated to undergo the operation under either general anaesthesia (GA) or under combined (epidural-spinal) (CESA) anaesthesia. Several parameters were recorded both preoperatively (medical history, biometric data, PSA, biopsy Gleason score) and postoperatively (blood pressure, heart rate, haemoglobin levels, operation time and total hospital stay). In addition, mean arterial pressure, change in heart rate, total blood loss, blood transfusions, SAS score, intravenous fluid administration and operation time were also noted down intraoperatively. Patient pain levels and total satisfaction were evaluated using appropriate questionnaires. At the 12-month follow-up, biochemical recurrence using PSA levels and urinary continence status were evaluated. RESULTS: A total of 60 patients were included (30 in each group). Intraoperatively, mean MAP and heart rate change was higher in the GA group (MAP+7,46, HR+27) and mean SAS was higher in the CESA group (+0.93). The time needed for patients' recovery was faster (-3.5 min) and hospitalization was shorter for patients in the CESA group (-0.6 days). Intraoperative blood loss, time for induction and duration of operation were not significantly different. Mean postoperative drop of haemoglobin was greater in the GA group (+0.56) while blood transfusions, VAS pain scores and amount of intravenous fluids did not differ significantly between the two groups. No complications were reported. Patient satisfaction and urinary continence were comparable between the groups and there were no cases of biochemical recurrence. CONCLUSIONS: Radical retropubic prostatectomy can safely be performed under combined (spinal epidural anaesthesia, with possible benefits of lower blood loss, less post-operative complications and earlier discharge. Both procedures have equal oncological and functional outcomes at the 12-month follow-up.

Risk for Arterial Thromboembolic Events (ATEs) in Patients with Advanced Urinary Tract Cancer (aUTC) Treated with First-Line Chemotherapy: Single-Center, Observational Study.

Arterial thromboembolism has been associated with cancer or its treatment. Unlike venous thromboembolism, the incidence and risk factors have not been extensively studied. Here, we investigated the incidence of arterial thromboembolic events (ATEs) in an institutional series of advanced urinary tract cancer (aUTC) treated with cytotoxic chemotherapy. The ATE definition included peripheral arterial embolism/thrombosis, ischemic stroke and coronary events. A total of 354 aUTC patients were analyzed. Most patients (95.2%) received platinum-based chemotherapy. A total of 12 patients (3.4%) suffered an ATE within a median time of 3.6 months from the start of chemotherapy. The most frequent ATE was ischemic stroke (n = 7). Two ATEs were fatal. The 6-month and 24-month incidence were 2.1% (95% confidence interval [CI]: 0.9-4.1) and 3.6% (95% CI: 1.9-6.2), respectively. Perioperative chemotherapy increased the risk for ATE by 5.55-fold. Tumors other than UTC and pure non-transitional cell carcinoma histology were also independent risk factors. No association with the type of chemotherapy was found. Overall, ATEs occur in 4.6% of aUTC patients treated with chemotherapy and represent a clinically relevant manifestation. Perioperative chemotherapy significantly increases the risk for ATE. The role of prophylaxis in high-risk groups should be prospectively studied.

Using Association Rules in Antimicrobial Resistance in Stone Disease Patients.

Association rule mining is a very popular unsupervised machine learning technique for discovering patterns in large datasets. Patients with stone disease commonly suffer from urinary tract infections (UTI), complicated by the emergence of antimicrobial resistance (AMR), due to the excessive use of antibiotics. In this study, we explore the use of association rule mining in the AMR profile of patients suffering from stone disease.

Cluster Analysis Assessment in Proposing a Surgical Technique for Benign Prostatic Enlargement.

Benign prostatic enlargement (BPE) is a common disease in men over 50 years old. The phenotype of patients with BPE is heterogenous, regarding both baseline patient characteristics and disease-related parameters. Treatment can be either medical-conservative or surgical. A great variety of surgical techniques are available for surgical management, with three of the most common being monopolar transurethral resection of the prostate (mTUR-P), bipolar transurethral resection of the prostate (bTUR-P), and bipolar transurethral vaporization of the prostate (bTUVis). The selection of each one of these depends on surgeon reasoning, equipment availability, patient characteristics, and preferences. Since all of these techniques are available in our Urology Department, and surgeons are skilled to perform each one of them, we performed a clustering analysis according to patient pre-operative characteristics, using the k-means algorithm, to compare clustering-related technique assignment with the real-life technique used.

Using machine learning techniques to predict antimicrobial resistance in stone disease patients.

PURPOSE: Artificial intelligence is part of our daily life and machine learning techniques offer possibilities unknown until now in medicine. This study aims to offer an evaluation of the performance of machine learning (ML) techniques, for predicting bacterial resistance in a urology department. METHODS: Data were retrieved from laboratory information system (LIS) concerning 239 patients with urolithiasis hospitalized in the urology department of a tertiary hospital over a 1-year period (2019): age, gender, Gram stain (positive, negative), bacterial species, sample type, antibiotics and antimicrobial susceptibility. In our experiments, we compared several classifiers following a tenfold cross-validation approach on 2 different versions of our dataset; the first contained only information of Gram stain, while the second had knowledge of bacterial species. RESULTS: The best results in the balanced dataset containing Gram stain, achieve a weighted average receiver operator curve (ROC) area of 0.768 and F-measure of 0.708, using a multinomial logistic regression model with a ridge estimator. The corresponding results of the balanced dataset, that contained bacterial species, achieve a weighted average ROC area of 0.874 and F-measure of 0.783, with a bagging classifier. CONCLUSIONS: Artificial intelligence technology can be used for making predictions on antibiotic resistance patterns when knowing Gram staining with an accuracy of 77% and nearly 87% when identifying specific microorganisms. This knowledge can aid urologists prescribing the appropriate antibiotic 24-48 h before test results are known.

Artificial intelligence supporting cancer patients across Europe-The ASCAPE project.

INTRODUCTION: Breast and prostate cancer survivors can experience impaired quality of life (QoL) in several QoL domains. The current strategy to support cancer survivors with impaired QoL is suboptimal, leading to unmet patient needs. ASCAPE aims to provide personalized- and artificial intelligence (AI)-based predictions for QoL issues in breast- and prostate cancer patients as well as to suggest potential interventions to their physicians to offer a more modern and holistic approach on cancer rehabilitation. METHODS AND ANALYSES: An AI-based platform aiming to predict QoL issues and suggest appropriate interventions to clinicians will be built based on patient data gathered through medical records, questionnaires, apps, and wearables. This platform will be prospectively evaluated through a longitudinal study where breast and prostate cancer survivors from four different study sites across the Europe will be enrolled. The evaluation of the AI-based follow-up strategy through the ASCAPE platform will be based on patients' experience, engagement, and potential improvement in QoL during the study as well as on clinicians' view on how ASCAPE platform impacts their clinical practice and doctor-patient relationship, and their experience in using the platform. ETHICS AND DISSEMINATION: ASCAPE is the first research project that will prospectively investigate an AI-based approach for an individualized follow-up strategy for patients with breast- or prostate cancer focusing on patients' QoL issues. ASCAPE represents a paradigm shift both in terms of a more individualized approach for follow-up based on QoL issues, which is an unmet need for cancer survivors, and in terms of how to use Big Data in cancer care through democratizing the knowledge and the access to AI and Big Data related innovations. TRIAL REGISTRATION: Trial Registration on clinicaltrials.gov: NCT04879563.

Denonvilliers' Fascia: The Prostate Border to the Outside World.

The fascial structure around the prostate has been a controversial issue for several decades, but its role in radical prostatectomy is crucial to achieving successful nerve-sparing surgery. One of the fasciae surrounding the prostate is Denonvilliers' fascia, forming its posterior border with the rectum and enclosing along its layers several fibers of the neurovascular bundle. This review focuses on embryological and anatomical points of Denonvilliers' fascia, aiming to provide a summary for the operating general surgeons and urologists of this area.
