Abstract
PURPOSE To develop a CT-based radiomic signature to predict biochemical recurrence (BCR) in prostate cancer patients after sRT guided by positron-emission tomography targeting prostate-specific membrane antigen (PSMA-PET). MATERIAL AND METHODS Consecutive patients, who underwent 68Ga-PSMA11-PET/CT-guided sRT from three high-volume centers in Germany, were included in this retrospective multicenter study. Patients had PET-positive local recurrences and were treated with intensity-modulated sRT. Radiomic features were extracted from volumes of interests on CT guided by focal PSMA-PET uptakes. After preprocessing, clinical, radiomics, and combined clinical-radiomic models were developed combining different feature reduction techniques and Cox proportional hazard models within a nested cross validation approach. RESULTS Among 99 patients, median interval until BCR was the radiomic models outperformed clinical models and combined clinical-radiomic models for prediction of BCR with a C-index of 0.71 compared to 0.53 and 0.63 in the test sets, respectively. In contrast to the other models, the radiomic model achieved significantly improved patient stratification in Kaplan-Meier analysis. The radiomic and clinical-radiomic model achieved a significantly better time-dependent net reclassification improvement index (0.392 and 0.762, respectively) compared to the clinical model. Decision curve analysis demonstrated a clinical net benefit for both models. Mean intensity was the most predictive radiomic feature. CONCLUSION This is the first study to develop a PSMA-PET-guided CT-based radiomic model to predict BCR after sRT. The radiomic models outperformed clinical models and might contribute to guide personalized treatment decisions.

Abstract
Computed tomography (CT) is used to diagnose urolithiasis, a prevalent condition. In order to establish the strongest foundation for the quantifiability of urolithiasis, this study aims to develop semi-automated urolithiasis segmentation methods for CT images that differ in terms of surface-partial-volume correction and adaptive thresholding. It also examines the diagnostic accuracy of these methods in terms of volume and maximum stone diameter. One hundred and one uroliths were positioned in an anthropomorphic phantom and prospectively examined in CT. Four different segmentation methods were developed and used to segment the uroliths semi-automatically based on CT images. Volume and maximum diameter were calculated from the segmentations. Volume and maximum diameter of the uroliths were measured independently by three urologists by means of electronic calipers. The average value of the urologists´ measurements was used as a reference standard. Statistical analysis was performed with multivariate Bartlett's test. Volume and maximum diameter were in very good agreement with the reference measurements (r>0.99) and the diagnostic accuracy of all segmentation methods used was very high. Regarding the diagnostic accuracy no difference could be detected between the different segmentation methods tested (p>0.55). All four segmentation methods allow for accurate characterization of urolithiasis in CT with respect to volume and maximum diameter of uroliths. Thus, a simple thresholding approach with an absolute value may suffice for robust determination of volume and maximum diameter in urolithiasis.

Abstract
Background Direct-to-consumer (DTC) online prescription platforms (OPP) for sexual health represent a potential paradigm shift in the diagnosis and treatment for sexual dysfunctions in the way men seek care. Knowledge of patients' risk profile using these platforms is limited. Aim To assess risk profiles of patients reaching out to health care professionals through their DTC. Methods Anonymized data originally collected between February 2021 to May 2022 by a DTC platform in the men's health care space were retrospectively analyzed. Data included the content of patient requests through a communication function, as well as the corresponding responses by the attending physician on staff. Each request was then assessed by two independent urologists and categorized by the level of the risk profile as well as the need to refer the patient to further medical evaluation. Results Of 585 patient requests, 531 (90.8%) were classified as low risk. In the high-risk group, 32 patients were recommended to schedule an urgent appointment at a specialist. Only three patients (0.5%) were advised to seek emergency care. The overall referral rate for both risk groups was 52.3%. The requests of 279 patients (47.7%) were assessed as digitally treatable. Almost all patients who were digitally treatable were low risk. Side effects accounted for only 9.6% of all requests in the low-risk group, compared with 46.3% in the high-risk group. Conclusion Overall, low-risk levels in the requests of patients using a DTC platform were reported, with almost half of them suitable to be solved digitally, whereas the other half required referral to an in-person specialist.

Abstract
Due to demographic change associated with an increase in patient numbers as well as the existing shortage of medical personnel, the German healthcare system will face a major challenge in patient care. In order to maintain high-quality patient care at a high level, the digitisation of urology should be driven forward promptly and forcefully as digital applications such as online appointment scheduling, video consultations, digital health applications (DiGAs) and others could significantly improve treatment efficiency. The long-planned introduction of the electronic patient record (ePA) will hopefully accelerate this process, and medical online platforms could also become a permanent part of new treatment methods, which could emerge from the urgently needed structural change towards more digital medicine, including questionnaire-based telemedicine. This transformation, which, already today, is urgently needed in the healthcare system, must be demanded and promoted by service providers, but also by policymakers and administration, in order to achieve the positive development of digitisation in (urological) medicine.

Abstract
BACKGROUND Standards for reporting surgical adverse events (AEs) vary widely within the scientific literature. Failure to adequately capture AEs hinders efforts to measure the safety of healthcare delivery and improve the quality of care. The aim of the present study is to assess the prevalence and typology of perioperative AE reporting guidelines among surgery and anesthesiology journals. MATERIALS AND METHODS In November 2021, three independent reviewers queried journal lists from the SCImago Journal & Country Rank (SJR) portal (www.scimagojr.com), a bibliometric indicator database for surgery and anesthesiology academic journals. Journal characteristics were summarized using SCImago, a bibliometric indicator database extracted from Scopus journal data. Quartile 1 (Q1) was considered the top quartile and Q4 bottom quartile based on the journal impact factor. Journal author guidelines were collected to determine whether AE reporting recommendations were included and, if so, the preferred reporting procedures. RESULTS Of 1409 journals queried, 655 (46.5%) recommended surgical AE reporting. Journals most likely to recommend AE reporting were: by category surgery (59.1%), urology (53.3%), and anesthesia (52.3%); in top SJR quartiles (i.e. more influential); by region, based in Western Europe (49.8%), North America (49.3%), and the Middle East (48.3%). CONCLUSIONS Surgery and anesthesiology journals do not consistently require or provide recommendations on perioperative AE reporting. Journal guidelines regarding AE reporting should be standardized and are needed to improve the quality of surgical AE reporting with the ultimate goal of improving patient morbidity and mortality.

Abstract
The systemic treatment of advanced prostate cancer (PCa) has undergone an absolute revolution in the past decade. Numerous new substances have been approved for all stages of advanced disease and treatment has been increasingly intensified. The focus continues to be on substances with an effect on the androgen receptor axis. In this review, approved treatment options for metastatic hormone-sensitive PCa (mHSPC), non-metastatic castration-refractory PCa (nmCRPC) and metastatic castration-refractory PCa (mCRPC) are summarized. A special focus is on novel hormone therapeutic agents. Based on recent trial data, potential triple combinations for mHSPC as well as treatment sequence options and novel targeted agents for mCRPC are also highlighted.

Abstract
BACKGROUND Multiparametric MRI (MpMRI) improves the detection of aggressive prostate cancer (PCa) subtypes. As cases of active surveillance (AS) increase and tumor progression triggers definitive treatment, we evaluated whether an AI-driven algorithm can detect clinically significant PCa (csPCa) in patients under AS. METHODS Consecutive patients under AS who received mpMRI (PI-RADSv2.1 protocol) and subsequent MR-guided ultrasound fusion (targeted and extensive systematic) biopsy between 2017 and 2020 were retrospectively analyzed. Diagnostic performance of an automated clinically certified AI-driven algorithm was evaluated on both lesion and patient level regarding the detection of csPCa. RESULTS Analysis of 56 patients resulted in 93 target lesions. Patient level sensitivity and specificity of the AI algorithm was 92.5%/31% for the detection of ISUP ≥ 1 and 96.4%/25% for the detection of ISUP ≥ 2, respectively. The only case of csPCa missed by the AI harbored only 1/47 Gleason 7a core (systematic biopsy; previous and subsequent biopsies rendered non-csPCa). CONCLUSIONS AI-augmented lesion detection and PI-RADS scoring is a robust tool to detect progression to clinically significant PCa in patients under AS. Integration in the clinical workflow can serve as reassurance for the reader and streamline reporting, hence improve efficiency and diagnostic confidence. This article is protected by copyright.

Abstract
INTRODUCTION Holmium laser enucleation of the prostate (HoLEP) has become popular worldwide for the surgical treatment of benign prostate hyperplasia. Holmium laser is considered an ideal transurethral thermomechanical device for enucleating the prostate. Although there is evidence on Ho:YAG laser-related heat generation, the studies mainly investigated ex vivo temperature generation during holmium laser lithotripsy. In this in vivo study, we aimed to assess for the first time the real-time heat generated during HoLEP. METHODS Fifteen HoLEP procedures were included. The study was conducted over a time period of 16 months. To investigate the temperature generation, a preoperatively inserted rectal temperature probe and a temperature sensor within a suprapubic bladder catheter were used to record the temperature change during enucleation and coagulation. RESULTS The mean values of the temperature change during the laser enucleation and coagulation were -0.35 ± 0.203 K (IQR: 0.23) and +0.14 ± 0.259 K (IQR: 0.3), respectively, in rectal measurements. Temperature differences during laser use and coagulation were <+1 K and <+5 K, respectively, in bladder measurements. We measured no temperature >37.1°C during the procedures and no temperature values considered harmful to the human body. CONCLUSION Sufficient irrigation flow rates and irrigation monitoring during HoLEP are obligatory. To prevent a high and uncontrolled temperature rise, the surgeon or operating room staff should pay attention to the irrigation's continuity.

Abstract
BACKGROUND As a local treatment for prostate cancer (PCa), robot-assisted radical prostatectomy (RARP) may have a quality of life (QoL) benefit over open surgery. Recent analyses revealed substantial between-country differences in the function and symptom scale scores for the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), which is typically used to assess patient-reported QoL. Such differences could have implications for multinational studies in PCa. OBJECTIVE To examine whether nationality is significantly associated with patient-reported QoL. DESIGN, SETTING, AND PARTICIPANTS The study cohort comprised Dutch and German patients with PCa treated with RARP in a single high-volume prostate center from 2006 to 2018. Analyses were restricted to patients who were preoperatively continent with at least one follow-up time point. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS QoL was measured in terms of the global Quality of Life (QL) scale score and the overall summary score for the EORTC QLQ-C30. Linear mixed models for repeated-measures multivariable analyses (MVAs) were used to examine the association between nationality and both the global QL score and the summary score. MVAs were further adjusted for QLQ-C30 baseline values, age, Charlson comorbidity index, preoperative prostate-specific antigen, surgical expertise, pathological tumor and nodal stage, Gleason grade, degree of nerve-sparing, surgical margin status, 30-d Clavien-Dindo grade complications, urinary continence recovery, and biochemical recurrence/postoperative radiotherapy. RESULTS AND LIMITATIONS For Dutch (n = 1938) versus German (n = 6410) men, the mean baseline scores were 82.8 versus 71.9 for the global QL scale score and 93.4 versus 89.7 for the QLQ-C30 summary score. Urinary continence recovery (QL: +8.9, 95% confidence interval [CI] 8.1-9.8; p < 0001) and Dutch nationality (QL: +6.9, 95% CI 6.1-7.6; p < 0001) were the strongest positive contributors to the global QL and summary scores, respectively. The main limitation is the retrospective study design. In addition, our Dutch cohort may not be representative of the general Dutch population and reporting bias cannot be ruled out. CONCLUSIONS Our findings provide observational evidence under specific conditions involving the same setting for patients of two different nationalities suggesting that cross-national patient-reported QoL differences appear to be real and may need to be taken into consideration in multinational studies. PATIENT SUMMARY We observed differences in the quality-of-life scores reported by Dutch and German patients with prostate cancer after they underwent robot-assisted removal of the prostate. These findings should be taken into consideration in cross-national studies.

Abstract
311 Background: The decision of performing prostate biopsy in men with equivocal findings in prostate magnetic resonance imaging (MRI) is challenging as they have a low but still relevant risk of harboring significant prostate cancer (sPC). Objective: To identify clinical predictors of sPC in men with equivocal findings in prostate MRI. Secondly, we aimed to analyze the hypothetical effect of incorporating prostate-specific antigen density (PSAD) into biopsy decision. Methods: We analysed a retrospective multinational cohort from 10 academic centers comprising 1476 men who underwent combined prostate biopsy (MRI-targeted plus systematic) between 02/2012 – 04/2021 due to an equivocal lesion found in prostate MRI (Prostate Imaging Reporting and Data System 3). Primary outcome was the detection of sPC (ISUP ≥ 2) in combined biopsy. Regression analysis was performed to identify predictors for this outcome. Descriptive statistics were applied to evaluate the hypothetical effect of involving PSAD into biopsy decision. Results: 273/1476 (18.5%) men were diagnosed with sPC by combined biopsy. MRI-targeted biopsy diagnosed less sPC as compared to combined strategy: 183/1476 (12.4%) vs. 273/1476 (18.5%), p<0.01. Regression analysis confirmed age (OR 1.10 [95% CI: 1.05 – 1.15]; p < 0.001), prior negative biopsy (OR 0.46 [0.24 – 0.89]; p = 0.022) and PSAD (p<0.001) as independent predictors for sPC. Applying a PSAD cut-off of 0.15 for biopsy decision, 817/1398 (58.4%) of the biopsy procedures would have been avoided at the cost of missing sPC in 91 (6.5%) men. Limitations were the retrospective design, heterogeneity of the study cohort due to the long inclusion period and a missing central revision of MRI. Conclusions: Age, previous biopsy status and PSAD were found independent predictors of sPC in men with equivocal prostate MRI. Implementation of PSAD into biopsy decision can avoid a large proportion of unnecessary biopsies. Clinical parameters such as PSAD need validation in a prospective setting.

Abstract
Current treatment for patients with metastatic hormone-sensitive prostate cancer (mHSPC) delays disease progression and improves survival, but resistance is inevitable. Additional therapies that prolong survival are needed. Androgen deprivation therapy (ADT) combined with next-generation hormonal agents, such as enzalutamide, is standard-of-care for men with mHSPC. Emerging evidence suggests potential synergism between enzalutamide and the PD-1 inhibitor pembrolizumab in prostate cancer. The phase III randomized, placebo-controlled, double-blind KEYNOTE-991 trial will investigate the efficacy and safety of pembrolizumab versus placebo in combination with enzalutamide when initiating ADT in participants with mHSPC naive to next-generation hormonal agents. Approximately 1232 patients will be randomly assigned 1:1 to receive pembrolizumab 200 mg every 3 weeks or placebo every 3 weeks, both with enzalutamide 160 mg once daily and ADT. Dual primary end points are overall survival and radiographic progression-free survival. Secondary end points include time to first subsequent therapy, time to symptomatic skeletal related event, objective response rate and safety and tolerability. Clinical Trial Registration: NCT04191096 (ClinicalTrials.gov).

Abstract
BACKGROUND Penile curvature is the most debilitating symptom of Peyronie's disease (PD); the evaluation of the degree of angulation is essential for planning treatment strategy. However, the most used method of penile at-home autophotography (AHP) is associated with some potential pitfalls and discrepancies compared with different assessment methods. OBJECTIVE To compare the degree of penile curvature quantified by AHP and in-office intracavernosal alprostadil injection (ICI) prior to therapy. DESIGN, SETTING, AND PARTICIPANTS Data from 55 PD patients of a single tertiary referral center were analyzed. All patients provided standardized AHP of the erect phallus. Clinic-based assessment included ICI with curvature measurement and completion of the International Index of Erectile Function (IIEF-15). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The Wilcoxon and/or chi-square test was used to compare the degree of curvature obtained using AHP and ICI, and to evaluate whether erectile dysfunction was a predictor of a relevant difference of >10° in curvature assessment between AHP and ICI. RESULTS AND LIMITATIONS Our study showed a significant (p < 0.001) difference in the degree of penile curvature between AHP (48° [38°; 55°]) and ICI (50° [40°; 65°]). Patients suffering from erectile dysfunction tend to have a higher difference in the degree of penile curvature between AHP and ICI than patients with good erectile function (p < 0.001). Our study is not devoid of limitations. First, we did not use Peyronie's Disease Questionnaire, as suggested by the European Association of Urology guidelines. Second, we did not evaluate inter- and intraobserver variations in the measurements. CONCLUSIONS AHP tends to underestimate the extent of penile curvature compared to ICI. Erectile dysfunction is an independent predictor of measurement differences of >10° between AHP and ICI. PATIENT SUMMARY It is necessary to evaluate the degree of penile curvature in Peyronie's disease prior to therapy decision. The at-home self-photography underestimates the real degree of penile curvature compared with an erection by in-office penile drug injection. Especially men suffering from erectile dysfunction carry the risk of a high difference in the measured degree of penile curvature, with a potential impact on the further treatment.

Abstract
CONTEXT Several sexual side effects, including erectile, ejaculatory, and orgasmic dysfunction, were reported with the majority of surgical procedures for benign prostatic obstruction (BPO). OBJECTIVE To systematically review current evidence regarding the impact of benign prostatic hyperplasia (BPH) surgery on sexual function. EVIDENCE ACQUISITION A comprehensive bibliographic search on the MEDLINE, Cochrane Library, Embase, Web of Science, and Google Scholar databases was conducted in July 2021. The population, intervention, comparator, and outcome (PICO) model was used to define study eligibility. Studies were Included if they assessed patients with BPO and related lower urinary tract symptoms (P) undergoing BPH surgery (I) with or without a comparison between surgical treatments (C) evaluating the impact on sexual function (O). Retrospective and prospective primary studies were included. A pooled analysis was conducted on studies including the postoperative assessment of International Index of Erectile Function (IIEF)-5, Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD; Function and/or Bother), or retrograde ejaculation (RE) rate (PROSPERO database ID: CRD42020177907). EVIDENCE SYNTHESIS A total of 151 studies investigating 20 531 patients were included. Forty-eight randomized controlled trials evaluating 5045 individuals were eligible for the meta-analysis. In most studies (122, 80.8%), only erectile and/or ejaculatory function was evaluated. A substantial number of articles (67, 44.4%) also used nonvalidated tools to evaluate erectile and/or ejaculatory function. The pooled analysis showed no statistically significant changes in IIEF-5 score compared with baseline for the transurethral resection of the prostate (TURP; weighted mean difference [WMD] 0.76 pts; 95% confidence interval [CI] -0.1, 1.62; p = 0.08), laser procedure (WMD 0.33 pts; 95% CI -0.1, 0.77; p = 0.13), and minimally invasive treatment (WMD -1.37 pts; 95% CI -3.19, 0.44; p = 0.14) groups. A statistically significantly higher rate of RE was found after TURP (risk ratio [RR] 13.31; 95% CI 8.37, 21.17; p < 0.00001), other electrosurgical procedures (RR 34.77; 95% CI 10.58, 127.82; p < 0.00001), and the entire laser group (RR 17.37; 95% CI 5.93, 50.81; p < 0.00001). No statistically significant increase in RE rate was described after most of the minimally invasive procedures (p > 0.05). The pooled analysis of MSHQ-EjD scores was possible only for prostatic urethral lift, showing no statistically significant difference between baseline and post-treatment MSHQ-EjD Function scores (WMD -0.80 pts; 95% CI -2.41, 0.81; p = 0.33), but postoperative MSHQ-EjD Bother scores were significantly higher (WMD 0.76 pts; 95% CI 0.22, 1.30; p = 0.006). CONCLUSIONS Erectile function appears to be unaffected by most surgical procedures for BPO. RE is a very common adverse event of BPH surgery, although emerging minimally invasive surgical procedures could be associated with a lower risk. PATIENT SUMMARY Benign prostatic hyperplasia surgery can have an impact on sexual function, mainly involving ejaculatory function.

Individualized Decision Making in Transperineal Prostate Biopsy: Should All Men Undergo an Additional Systematic Biopsy? Cancers (Basel) 2022; 14:cancers14215230. [PMID: 36358650 PMCID: PMC9657738 DOI: 10.3390/cancers14215230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Revised: 10/17/2022] [Accepted: 10/21/2022] [Indexed: 11/25/2022] Open
Abstract
Background: In prostate cancer (PC) diagnosis, additional systematic biopsy (SB) is recommended to complement MRI-targeted biopsy (TB) to address the limited sensitivity of TB alone. The combination of TB+SB is beneficial for diagnosing additional significant PC (sPC) but harmful in terms of the additional diagnosis of indolent PC (iPC), morbidity, and resource expenditures. We aimed to investigate the benefit of additional SB and to identify predictors for this outcome. Methods: We analyzed the frequency of upgrading to sPC by additional SB in a retrospective single-center cohort of 1043 men. Regression analysis (RA) was performed to identify predictors for this outcome. Reclassification rates of ISUP grade groups between prostate biopsy and a subsequent radical prostatectomy were assessed. Results: Additional SB led to upgrading to sPC in 98/1043 men (9.4%) and to the additional diagnosis of iPC in 71/1043 (6.8%). In RA, men harboring a PI-RADS 2-4 lesion were more likely to have TB results upgraded by SB (p < 0.01) compared to PI-RADS 5 men. When analyzing reclassification rates, additional SB reduced the upgrading to sPC from 43/214 (20.1%) to 8/214 (3.7%). In the PI-RADS 5 subgroup, this difference decreased: 4/87 (4.7%) with TB only vs. 1/87 (1.2%) with TB+SB. Conclusion: Men with a PI-RADS 5 lesion may obviate additional SB.

Abstract
INTRODUCTION The Prostate Imaging Reporting and Data System (PI-RADS) standardises reporting of prostate MRI for the detection of clinically significant prostate cancer. We provide the protocol of a planned living systematic review and meta-analysis for (1) diagnostic accuracy (sensitivity and specificity), (2) cancer detection rates of assessment categories and (3) inter-reader agreement. METHODS AND ANALYSIS Retrospective and prospective studies reporting on at least one of the outcomes of interest are included. Each step that requires literature evaluation and data extraction is performed by two independent reviewers. Since PI-RADS is intended as a living document itself, a 12-month update cycle of the systematic review and meta-analysis is planned.This protocol is in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Protocols statement. The search strategies including databases, study eligibility criteria, index and reference test definitions, outcome definitions and data analysis processes are detailed. A full list of extracted data items is provided.Summary estimates of sensitivity and specificity (for PI-RADS ≥3 and PI-RADS ≥4 considered positive) are derived with bivariate binomial models. Summary estimates of cancer detection rates are calculated with random intercept logistic regression models for single proportions. Summary estimates of inter-reader agreement are derived with random effects models. ETHICS AND DISSEMINATION No original patient data are collected, ethical review board approval, therefore, is not necessary. Results are published in peer-reviewed, open-access scientific journals. We make the collected data accessible as supplemental material to guarantee transparency of results. PROSPERO REGISTRATION NUMBER CRD42022343931.

Abstract
The recommendations on carrying out a multiparametric magnetic resonance imaging (mpMRI) for the primary diagnostics and during active surveillance of prostate cancer, include as a consequence an image-guided sampling from conspicuous areas. In doing so, the information on the localization provided by mpMRI is used for a targeted biopsy of the area suspected of being a tumor. The targeted sampling is mainly performed under sonographic control and after fusion of MRI and ultrasound but can also be (mostly in special cases) carried out directly in the MRI scanner. In an ultrasound-guided biopsy, it is vital to coregister the MR images with the ultrasound images (segmentation of the contour of the prostate and registration of suspect findings). This coregistration can either be carried out cognitively (transfer by the person performing the biopsy alone) or software based. Each method shows specific advantages and disadvantages in the prioritization between diagnostic accuracy and resource expenditure.

Abstract
Purpose This study aims to evaluate the association of the maximum standardized uptake value (SUVmax) in positron-emission tomography targeting prostate-specific membrane antigen (PSMA-PET) prior to salvage radiotherapy (sRT) on biochemical recurrence free survival (BRFS) in a large multicenter cohort. Methods Patients who underwent 68 Ga-PSMA11-PET prior to sRT were enrolled in four high-volume centers in this retrospective multicenter study. Only patients with PET-positive local recurrence (LR) and/or nodal recurrence (NR) within the pelvis were included. Patients were treated with intensity-modulated-sRT to the prostatic fossa and elective lymphatics in case of nodal disease. Dose escalation was delivered to PET-positive LR and NR. Androgen deprivation therapy was administered at the discretion of the treating physician. LR and NR were manually delineated and SUVmax was extracted for LR and NR. Cox-regression was performed to analyze the impact of clinical parameters and the SUVmax-derived values on BRFS. Results Two hundred thirty-five patients with a median follow-up (FU) of 24 months were included in the final cohort. Two-year and 4-year BRFS for all patients were 68% and 56%. The presence of LR was associated with favorable BRFS (p = 0.016). Presence of NR was associated with unfavorable BRFS (p = 0.007). While there was a trend for SUVmax values ≥ median (p = 0.071), SUVmax values ≥ 75% quartile in LR were significantly associated with unfavorable BRFS (p = 0.022, HR: 2.1, 95%CI 1.1–4.6). SUVmax value in NR was not significantly associated with BRFS. SUVmax in LR stayed significant in multivariate analysis (p = 0.030). Sensitivity analysis with patients for who had a FU of > 12 months (n = 197) confirmed these results. Conclusion The non-invasive biomarker SUVmax can prognosticate outcome in patients undergoing sRT and recurrence confined to the prostatic fossa in PSMA-PET. Its addition might contribute to improve risk stratification of patients with recurrent PCa and to guide personalized treatment decisions in terms of treatment intensification or de-intensification.

Abstract
Despite decades of research and successful improvements in diagnosis and therapy, prostate cancer (PC) remains a major challenge. In recent years, it has become clear that PC stem cells (PCSCs) are the driving force in tumorigenesis, relapse, metastasis, and therapeutic resistance of PC. In this minireview, we discuss the impact of PCSCs in the clinical practice. Moreover, new therapeutic approaches to combat PCSCs are presented with the aim to achieve an improved outcome for patients with PC.

Abstract
CONTEXT Urinary incontinence (UI) is a common condition in elderly men causing a severe worsening of quality of life, and a significant cost for both patients and health systems. OBJECTIVE To report a practical, evidence-based, guideline on definitions, pathophysiology, diagnostic workup, and treatment options for men with different forms of UI. EVIDENCE ACQUISITION A comprehensive literature search, limited to studies representing high levels of evidence and published in the English language, was performed. Databases searched included Medline, EMBASE, and the Cochrane Libraries. A level of evidence and a grade of recommendation were assigned. EVIDENCE SYNTHESIS UI can be classified into stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence. A detailed description of the pathophysiology and diagnostic workup has been reported. Simple clinical interventions, behavioural and physical modifications, and pharmacological treatments comprise the initial management for all kinds of UI. Surgery for SUI includes bulking agents, male sling, and compression devices. Surgery for UUI includes bladder wall injection of botulinum toxin A, sacral nerve stimulation, and cystoplasty/urinary diversion. CONCLUSIONS This 2022 European Association of Urology guideline summary provides updated information on definition, pathophysiology, diagnosis, and treatment of male UI. PATIENT SUMMARY Male urinary incontinence comprises a broad subject area, much of which has been covered for the first time in the literature in a single manuscript. The European Association of Urology Non-neurogenic Male Lower Urinary Tract Symptoms Guideline Panel has released this new guidance, with the aim to provide updated information for urologists to be able to follow diagnostic and therapeutic indications for optimising patient care.
