RESUMO
INTRODUCTION: Systematic evaluations focusing on the perception of body image and social support in relation to quality of life (QoL) outcomes in patients RC with UD are currently lacking. This study investigated the relationship between body image perception, social support, and QoL in bladder cancer patients who underwent radical cystectomy (RC) with urinary diversion (UD). METHODS: A cross-sectional survey was conducted using validated general oncology tools to assess QoL in relation to newly implemented tools assessing body image perception and social support. Body image perception was assessed with the Self-Image Scale, and social support was assessed using the Illness-Specific Social Support Scale. Logistic regression models were used to analyze factors associated with QoL and body image respectively. RESULTS: The survey revealed a significant association of body image perception with QoL, as well as social support with body image perception. This is the first study to systematically evaluate these psychosocial factors in the context of QoL for RC patients, highlighting their critical role in patient-reported outcomes. CONCLUSION: Body image perception and social support are important psychosociological factors that affect QoL of bladder cancer patients post-RC. Targeted psychosocial interventions could be promising for improving QoL patients post-RC.
RESUMO
Introduction: Before holmium laser enucleation of the prostate (HoLEP), many patients have undergone short-term prostate biopsy (PB) to rule out the presence of prostate cancer. The aim of this study is to determine whether a short-term PB before HoLEP has an impact on the perioperative outcomes or complications of HoLEP. Methods: In total, 734 consecutive patients treated with HoLEP at a tertiary care university hospital between January 2021 and July 2023 were retrospectively enrolled. Patients who had PB within 6 months before HoLEP were matched to patients who underwent PB more than 6 months or had no PB before HoLEP using propensity score matching (PSM) based on age, prostate volume (PV), prostate-specific antigen (PSA), preoperative urinary tract infection (UTI), and surgeon. Perioperative parameters, such as operation time (OT), enucleation efficiency (EF), as well as complications according to the Satava classification, the Clavien-Dindo classification (CDC), and the Comprehensive Complication Index (CCI) were evaluated. Results: In total, 206 patients were matched. Age, PV, PSA, as well as the presence of a preoperative UTI and surgeons did not differ significantly between both groups after PSM. There were no significant differences in mean OT (75 vs. 81 minutes, p = 0.28) and EF (2.13 vs. 2.13 g/min, p = 0.99). No differences were noted regarding intraoperative (16 vs. 25, p = 0.16) or postoperative complications graded by CDC (p = 0.53) and CCI (p = 0.92). Conclusion: PB within 6 months preoperatively before HoLEP showed no effect on perioperative outcomes or intra- and postoperative complications.

BACKGROUND: Urinary bladder tamponade is a urological emergency that is part of the clinical routine of every urologist and requires immediate and adequate diagnosis and therapy. OBJECTIVES: Presentation of the clinical picture of urinary bladder tamponade including etiology, diagnostics, and therapy as well as formulation of recommendations for action for clinical routine. MATERIALS AND METHODS: Structured presentation of the diagnosis and therapy of urinary bladder tamponade with practical recommendations for action based on a current literature search and a clinical case study. RESULTS: Urinary bladder tamponade is a usually painful filling of the urinary bladder with blood clots as part of gross hematuria. The central pillars of diagnostics are anamnesis, targeted physical examination, and sonography. Therapy involves the rapid insertion of a flushing catheter with manual evacuation of the tamponade. A flushing catheter with at least 20 French should be used here. CONCLUSION: Timely diagnosis and prompt treatment are crucial. This usually includes transurethral catheter insertion with manual evacuation. If the tamponade is unsuccessfully removed, further measures such as endoscopic evacuation or, as a last resort, sectio alta or radical cystectomy are available.

INTRODUCTION AND OBJECTIVES: Challenging percutaneous renal punctures to gain access to the kidney requiring guidance by cross-sectional imaging. To test the feasibility of robotic-assisted CT-guided punctures (RP) and compare them with manual laser-guided punctures (MP) with Uro Dyna-CT (Siemens Healthcare Solutions, Erlangen, Germany). MATERIAL AND METHODS: The silicon kidney phantom contained target lesions of three sizes. RP were performed using a robotic assistance system (guidoo, BEC GmbH, Pfullingen, Germany) with a robotic arm (LBR med R800, KUKA AG, Augsburg, Germany) and a navigation software with a cone-beam-CT Artis zeego (Siemens Healthcare GmbH, Erlangen, Germany). MP were performed using the syngo iGuide Uro-Dyna Artis Zee Ceiling CT (Siemens Healthcare Solutions). Three urologists with varying experience performed 20 punctures each. Success rate, puncture accuracy, puncture planning time (PPT), and needle placement time (NPT) were measured and compared with ANOVA and Chi-Square Test. RESULTS: One hundred eighteen punctures with a success rate of 100% for RP and 78% for MP were included. Puncture accuracy was significantly higher for RP. PPT (RP: 238 ± 90s, MP: 104 ± 21s) and NPT (RP: 128 ± 40s, MP: 81 ± 18s) were significantly longer for RP. The outcome variables did not differ significantly with regard to levels of investigators' experience. CONCLUSION: The accuracy of RP was superior to that of MP. This study paves the way for first in-human application of this robotic puncture system.

BACKGROUND: Shared decision-making is the gold standard for good clinical practice, and thus, psychometric instruments have been established to assess patients' generic preference for participation (e.g., the Autonomy Preference Index, API). However, patients' preferences may vary depending on the specific disease and with respect to the specific decision context. With a modified preference index (API-Uro), we assessed patients' specific participation preference in preference-sensitive decisions pertaining to urological cancer treatments and compared this with their generic participation preference. METHODS: In Study 1, we recruited (N = 469) urological outpatients (43.1% urooncological) at a large university hospital. Participation preference was assessed with generic measures (API and API case vignettes) and with the disease-specific API-Uro (urooncological case vignettes describing medical decisions of variable difficulty). A polychoric exploratory factor analysis was used to establish factorial validity and reduce items. In Study 2, we collected data from N = 204 bladder cancer patients in a multicenter study to validate the factorial structure with confirmatory factor analysis. Differences between the participation preference for different decision contexts were analyzed. RESULTS: Study 1: Scores on the specific urooncological case vignettes (API-Uro) correlated with the generic measure (r = .44) but also provided incremental information. Among the disease-specific vignettes of the API-Uro, there were two factors with good internal consistency (α ≥ .8): treatment versus diagnostic decisions. Patients desired more participation for treatment decisions (77.8%) than for diagnostic decisions (22%), χ2(1) = 245.1, p ≤ .001. Study 2: Replicated the correlation of the API-Uro with the API (r = .39) and its factorial structure (SRMR = .08; CFI = .974). Bladder cancer patients also desired more participation for treatment decisions (57.4%) than for diagnostic decisions (13.3%), χ²(1) =84, p ≤ .001. CONCLUSIONS: The desire to participate varies between treatment versus diagnostic decisions among urological patients. This underscores the importance of assessing participation preference for specific contexts. Overall, the new API-Uro has good psychometric properties and is well suited to assess patients' preferences. In routine care, measures of participation preference for specific decision contexts may provide incremental, allowing clinicians to better address their patients' individual needs.

INTRODUCTION: First external validation of the Bladder Complexity Score (BCS) for predicting complex transurethral resection of bladder tumours (TURBT). METHODS: For BCS calculation, TURBTs performed at our institution between January 2018 and December 2019 were reviewed for the presence of preoperative characteristics listed in the Bladder Complexity Checklist (BCC). Receiver operating characteristics (ROC) analysis was used for BCS validation. To establish a modified BCS (mBCS) with maximum area under the curve (AUC), multivariable logistic regression (MLR) analysis was performed with all BCC-characteristics for different definitions of complex TURBT. RESULTS: 723 TURBTs were included in statistical analyses. Cohort's mean BCS was 11.2 ± 2.4 points (range: 5.5-22 points). In ROC analysis, BCS could not predict complex TURBT (AUC 0.573 [95% CI: 0.517-0.628]). MLR identified tumour size (OR 2.662, p < 0.001), and tumour number > 10 (OR 6.390, p = 0.032) as sole predictors for the modified endpoint of complex TURBT defined as a procedure meeting > 1 criterion: incomplete resection, surgery > 1 h, intraoperative complication, postoperative complications Clavien-Dindo ≥ III. mBCS increased the prediction to an AUC of 0.770 (95% CI: 0.667-0.874). CONCLUSION: In this first external validation, BCS remained an insufficient predictor of complex TURBT. mBCS requires reduced parameters, is more predictive and easier to apply in clinical practice.

INTRODUCTION: Certain sociodemographic characteristics (e.g., older age) have previously been identified as barriers to patients' participation preference in shared decision-making (SDM). We aim to demonstrate that this relationship is mediated by the perceived power imbalance that manifests itself in patients' negative attitudes and beliefs about their role in decision-making. METHODS: We recruited a large sample (N = 434) of outpatients with a range of urological diagnoses (42.2% urooncological). Before the medical consultation at a university hospital, patients completed the Patients' Attitudes and Beliefs Scale and the Autonomy Preference Index. We evaluated attitudes as a mediator between sociodemographic factors and participation preference in a path model. RESULTS: We replicated associations between relevant sociodemographic factors and participation preference. Importantly, attitudes and beliefs about one's own role as a patient mediated this relationship. The mediation path model explained a substantial proportion of the variance in participation preference (27.8%). Participation preferences and attitudes did not differ for oncological and nononcological patients. CONCLUSION: Patients' attitudes and beliefs about their role determine whether they are willing to participate in medical decision-making. Thus, inviting patients to participate in SDM should encompass an assessment of their attitudes and beliefs. Importantly, negative attitudes may be accessible to change. Unlike stable sociodemographic characteristics, such values are promising targets for interventions to foster more active participation in SDM. PATIENT OR PUBLIC CONTRIBUTION: This study was part of a larger project on implementing SDM in urological practice. Several stakeholders were involved in the design, planning and conduction of this study, for example, three authors are practising urologists, and three are psychologists with experience in patient care. In addition, the survey was piloted with patients, and their feedback was integrated into the questionnaire. The data presented in this study is based on patients' responses. Results may help to empower our patients.

INTRODUCTION: This study aimed to assess patient compliance with a newly established electronic patient-reported outcome measure (ePROM) system after urologic surgery and to identify influencing factors. METHODS: Digital surveys were provided to patients undergoing cystectomy, radical or partial nephrectomy, or transurethral resection of bladder tumor via a newly established ePROM system. Participants received a baseline survey preoperatively and several follow-up surveys postoperatively. Multivariable regression analysis was performed to identify factors predicting compliance. RESULTS: Of N = 435 eligible patients, n = 338 completed the baseline survey (78.0%). Patients who did not participate were significantly more likely male (p = 0.004) and older than 70 years (p = 0.005). Overall, 206/337 patients (61.3%) completed the survey at 1-month, 167/312 (53.5%) at 3-month, and 142/276 (51.4%) at 6-month follow-up. Lower baseline quality of life (odds ratio: 2.27; p = 0.004) was a significant predictor for dropout at 1-month follow-up. Low educational level was significantly associated with low compliance at 3- (OR: 1.92; p = 0.01) and 6-month follow-up (OR: 2.88; p < 0.001). CONCLUSION: Acceptable compliance rates can be achieved with ePROMs following urologic surgery. Several factors influence compliance and should be considered when setting-up ePROM surveys.

PURPOSE: Advances in therapy of metastatic castration-refractory prostate cancer (mCRPC) resulted in more therapeutic options and led to a higher need of predictive/prognostic biomarkers. Systemic inflammatory biomarkers could provide the basis for personalized treatment selection. This study aimed to assess the modified Glasgow Prognostic Score (mGPS), the neutrophile-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR) and the systemic immune-inflammation index (SII) in men with mCRPC under docetaxel. METHODS: Patients with mCRPC and taxane chemotherapy at a tertiary care centre between 2010 and 2019 were screened retrospectively. The biomarkers mGPS, NLR, PLR and SII were assessed and analyzed for biochemical/radiologic response and survival. RESULTS: We included 118 patients. Of these, 73 (61.9%) had received docetaxel as first-line, 31 (26.2%) as second-line and 14 (11.9%) as third-line treatment. For biochemical response, mGPS (odds ratio (OR) 0.54, p = 0.04) and PLR (OR 0.63, p = 0.04) were independent predictors in multivariable analysis. SII was significant in first-line cohort only (OR 0.29, p = 0.02). No inflammatory marker was predictive for radiologic response. In multivariable analysis, mGPS and NLR (hazard ratio (HR) 1.71 and 1.12, both p < 0.01) showed significant association with OS in total cohort and mGPS in the first-line cohort (HR 2.23, p < 0.01). Haemoglobin (Hb) and alkaline phosphatase (AP) showed several significant associations regarding 1 year, 3 year, OS and biochemical/radiologic response. CONCLUSIONS: Pre-treatment mGPS seems a promising prognostic biomarker. A combination of mGPS, NLR and further routine markers (e.g., Hb and AP) could yield optimized stratification for treatment selection. Further prospective and multicentric assessment is needed.

Objective: To evaluate perioperative parameters, clinical outcomes, and the learning curve of holmium laser enucleation of the prostate (HoLEP) in surgeons with experience in thulium laser enucleation of the prostate (ThuLEP). Materials and Methods: The learning curves for HoLEP of the first 50 consecutive patients of two surgeons experienced in ThuLEP were analyzed. In addition, demographic parameters, clinical outcomes, and adverse events (AEs) were evaluated. Results: Mean operation time was 70.9 ± 29.7 minutes (standard deviation) (Surgeon 1) and 74.4 ± 35.4 minutes (Surgeon 2), the mean enucleation efficiency was 1.5 ± 0.6 g/min (Surgeon 1) and 1.5 ± 0.7 g/min (Surgeon 2). The hemoglobin loss was 0.9 ± 0.8 and 0.8 ± 0.8 g/dL. For both surgeons, there was a significant learning curve in enucleation efficiency within the first 50 cases (Surgeon 1: p = 0.034, Surgeon 2: p = 0.006, both: p = 0.0003, Spearman's ρ = 0.351). Both surgeons started with an enucleation efficiency of around 1 g/min in their first 10 cases. No significant correlation between hemoglobin loss and experience could be found (p = 0.823, ρ = 0.025). While there was no significant learning curve for morcellation efficiency (p = 0.785, ρ = 0.028), a significant progress was found for one of the two surgeons regarding laser energy efficiency (p = 0.014). The overall incidence of all grade treatment-related AEs was low at 10.0%, and extremely low for significant complications with Clavien-Dindo Grade >II at 1%. Conclusions: In our analysis, switching to HoLEP is uncomplicated and safe for experienced ThuLEP surgeons. The enucleation efficiency was high from the beginning, but a learning curve was present for both surgeons. No learning curve was noticeable in hemoglobin loss and the incidence of complications, both of which were low throughout the study.

BACKGROUND/AIM: To assess the baseline inflammatory markers modified Glasgow Prognostic Score (mGPS), systemic immune-inflammation index (SII), and neutrophile-to-lymphocyte ratio (NLR) as pragmatic tools for predicting response to chemohormonal therapy (docetaxel plus ADT) and prognosis in men with metastatic hormone-sensitive prostate cancer (mHSPC). PATIENTS AND METHODS: Male patients who received docetaxel at a tertiary university care center between 2014 and 2019 were screened for completion of 6 cycles. NLR, SII, mGPS, overall survival (OS), three-year survival, and radiologic response were assessed. Complete response (CR), partial response (PR), and stable disease (SD) were analyzed alone and in combination. RESULTS: Thirty-six mHSPC-patients were included. In thirty patients, baseline mGPS was assessed and was either 0 (n=22) or 2 (n=8). In Cochran-Armitage Trend Test, mGPS showed significant association with the combined radiologic endpoint of "CR, PR, or SD" (p=0.01), three-year survival (p=0.02), and OS (p<0.01). Next to prostate-specific antigen (PSA) (HR per 100 units 1.16, 95%CI=1.04-1.30, p<0.01), NLR (HR=1.31, 95%CI=1.03-1.66, p=0.03), and mGPS (2 vs. 0, HR=6.53, 95%CI=1.6-27.0, p<0.01) at baseline showed significant association with OS in univariable cox regression. However, mGPS remained the only independent predictor for OS in multivariable cox regression (p<0.01) and for the combined radiologic endpoint of "CR, PR or SD" (p=0.01) in multivariable logistic regression. SII showed no statistical relevance. CONCLUSION: Baseline mGPS seems to be a pragmatic tool for clinical decision-making in patients with mHSPC in daily routine.

OBJECTIVE: Patient-centered care and shared decision making (SDM) are generally recognized as the gold standard for medical consultations, especially for preference-sensitive decisions. However, little is known about psychological patient characteristics that influence patient-reported preferences. We set out to explore the role of personality and anxiety for a preference-sensitive decision in bladder cancer patients (choice of urinary diversion, UD) and to determine if anxiety predicts patients' participation preferences. METHODS: We recruited a sample of bladder cancer patients (N = 180, primarily male, retired) who awaited a medical consultation on radical cystectomy and their choice of UD. We asked patients to fill in a set of self-report questionnaires before this consultation, including measures of treatment preference, personality (BFI-10), anxiety (STAI), and participation preference (API and API-Uro), as well as sociodemographic characteristics. RESULTS: Most patients (79%) indicated a clear preference for one of the treatment options (44% continent UD, 34% incontinent UD). Patients who reported more conscientiousness were more likely to prefer more complex methods (continent UD). The majority (62%) preferred to delegate decision making to healthcare professionals. A substantial number of patients reported elevated anxiety (32%), and more anxiety was predictive of higher participation preference, specifically for uro-oncological decisions (ß = 0.207, p < 0.01). CONCLUSIONS: Our findings provide insight into the role of psychological patient characteristics for SDM. Aspects of personality such as conscientiousness influence treatment preferences. Anxiety contributes to patients' motivation to be involved in pertinent decisions. Thus, personality and negative affect should be considered to improve SDM.

PURPOSE: To analyze and share our experience with ultra-mini-PCNL using the urological Dyna-CT in small infants. METHODS: A retrospective analysis was performed on all infants younger than 3 years of age who underwent ultra-mini-PCNL at our institution since 2016. Operating time, fluoroscopy time, dose area product (DAP), stone-free status, intra- and postoperative complications and the duration of hospital stay were analyzed. RESULTS: A total of nine interventions conducted on eight children were evaluated. The mean age of infants was 22.8 ± 11.9 months. The mean operation time and the mean fluoroscopy time were 119.2 ± 51.8 min, and 190.4 ± 93.8 s, respectively. The mean DAP was 11.4 ± 6.9 µGym2 and the stone clearance at 3 months was 87.5%. No major postoperative complications were assessed, and no transfusion was given. The mean hospital stay was 4 (IQR 3-6) days. CONCLUSION: Ultra-mini-PCNL utilizing the urological Dyna-CT can safely and effectively be performed in small infants with kidney stones. In this setting, the urological Dyna-CT allows for a very low radiation exposure.

BACKGROUND: Thulium laser enucleation of the prostate (ThuLEP) is an established treatment option for benign prostatic enlargement (BPE), but long-term outcomes have not yet been reported. OBJECTIVE: To prove the durability of ThuLEP by investigating its long-term efficacy and morbidity. DESIGN, SETTING, AND PARTICIPANTS: All patients who underwent ThuLEP at a German tertiary referral center between 2009 and 2021 were retrospectively followed up for reinterventions for persistence or regrowth of prostate adenoma (ReIP) or long-term complications (ReIC). INTERVENTION: ThuLEP. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We calculated the cumulative incidence for ReIP and ReIC at 10 yr. Univariate and multivariate Cox regression models were constructed to identify predictors of ReIP and ReIC. RESULTS AND LIMITATIONS: Overall, 1097 patients underwent ThuLEP. The median overall follow-up was 6.0 yr (interquartile range [IQR] 2.4-9.2). For one-third of patients (n = 369), median follow-up of 10 yr (IQR 9.1-11.2) was available. A total of 42 patients (3.8%) underwent ReIP after a median of 2 yr (IQR 0.3-4.9). The rate of long-term ReIC was 2.6% (n = 29) and the median time to ReIC was 0.5 yr (IQR 0.3-1.7). The most frequent ReIC was urethrotomy (n = 16, 1.5%). The cumulative incidence of ReIP and ReIC at 10 yr was estimated at 5.6% and 3.4%, respectively. Enucleation weight ≥60 g was a significant predictor of ReIP (hazard ratio 1.2, p = 0.014). The retrospective study design and the lack of functional outcomes are the main limitations. CONCLUSIONS: ThuLEP is a durably effective and safe procedure with low reintervention rates within 12 yr. PATIENT SUMMARY: This study investigated long-term outcomes of thulium laser enucleation of the prostate for benign enlargement of the prostate (BPE). Low rates of repeat treatment for BPE recurrence or for other complications were observed. Our results show the safety and efficacy of this treatment over a period of 12 years.

INTRODUCTION: The methods employed to document cystoscopic findings in bladder cancer patients lack accuracy and are subject to observer variability. We propose a novel endoimaging system and an online documentation platform to provide post-procedural 3D bladder reconstructions for improved diagnosis, management and follow-up. MATERIAL AND METHODS: The RaVeNNA4pi consortium is comprised of five industrial partners, two university hospitals and two technical institutes. These are grouped into hardware, software and clinical partners according to their professional expertise. The envisaged endoimaging system consists of an innovative cystoscope that generates 3D bladder reconstructions allowing users to remotely access a cloud-based centralized database to visualize individualized 3D bladder models from previous cystoscopies archived in DICOM format. RESULTS: Preliminary investigations successfully tracked the endoscope's rotational and translational movements. The structure-from-motion pipeline was tested in a bladder phantom and satisfactorily demonstrated 3D reconstructions of the processing sequence. AI-based semantic image segmentation achieved a 0.67 dice-score-coefficient over all classes. An online-platform allows physicians and patients to digitally visualize endoscopic findings by navigating a 3D bladder model. CONCLUSIONS: Our work demonstrates the current developments of a novel endoimaging system equipped with the potential to generate 3D bladder reconstructions from cystoscopy videos and AI-assisted automated detection of bladder tumors.

CONTEXT: Decision aids (DAs) aim to support patients in the process of shared decision-making for complex treatment decisions. To improve patient-centered care in uro-oncology, it is essential to evaluate the availability and quality of existing DAs. OBJECTIVE: To assess the quality of existing DAs for patients across the most prevalent uro-oncological entities. EVIDENCE ACQUISITION: This study was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. A systematic literature search (MedLine, Cochrane Library, Web of Science Core Collection, and CCMed) was conducted to identify DAs for treatment decisions for patients with prostate, renal, or bladder cancer. All studies reporting on the development or evaluation of DAs were included. The DAs were examined based on the International Patient Decision Aid Standards (IPDAS) and the evaluation studies were compared in accordance with Standards for Universal reporting of a patient Decision Aid Evaluations (SUNDAE). EVIDENCE SYNTHESIS: The literature search identified 1995 potentially relevant publications. Thirty-two studies reporting on 25 DAs met the inclusion criteria. Twenty-two DAs address prostate cancer, two renal tumor, and one bladder cancer. In the majority of DAs (n = 20), patients can enter individual data. A few (n = 6) DAs allow for personalization using a risk-adapted presentation of treatment options. The percentage of IPDAS criteria met in DAs ranged between 50% and 100% (median 87.5%), and the studies' adherence to the SUNDAE checklist was between 62% and 96% (median 86.6%). Evaluation studies suggest that interventions are likely efficacious. However, a preliminary meta-analysis revealed no significant difference between "DA" and "usual care" for decisional conflict or decisional regret. CONCLUSIONS: This review highlights that a number of well-developed DAs exist in urology. However, there is a need for specific instruments targeting kidney and bladder cancer. Personalization of tools and adherence to international standards of DAs should be further improved. PATIENT SUMMARY: The majority of uro-oncological decision aids target prostate cancer, whereas fewer address kidney or bladder cancer. The quality of the existing instruments is high, but can be increased further to better address specific needs of individual patients.

PURPOSE: To assess the efficacy of prophylaxis for urinary tract infections (UTI) in a two-year follow-up in women with StroVac compared to a therapy with Nitrofurantoin over three months. MATERIALS AND METHODS: All patients with documented recurrent urinary tract infections (rUTI) were offered vaccination with StroVac or therapy with three months Nitrofurantoin 100 mg once daily for three months at patient's choice. Only patients with a follow-up of at least 24 months were included. All episodes with signs of UTI were documented and urine culture was performed. Success was defined as one or none UTI per 12 months, documented by urine culture. StroVac booster injection was offered 12 months after primary vaccination at patient's choice. RESULTS: 173 patients were included in this study, 124 in the StroVac group, 49 chose Nitrofuratoin. In the first 12 months, 86.8% of patients in the StroVac group and 91.8% in Nitrofurantoin group were successful (p = 0.22). Side effects were noted in 2.3% in the StroVac group causing discontinuation of therapy, whereas in the Nitrofurantoin group 18.4% stopped medication premature, mostly due to mild diarrhoea. In the second year 79.3% of patients in the StroVac group were still successful, most of them had undergone booster injection. In contrast, in the Nitrofurantoin group only 59.2% of patients were still successful (p = 0.03). CONCLUSION: StroVac is an effective and lasting non-antibiotic prophylaxis for rUTI, easy to administer with low rates of adverse events and should be offered to patients with rUTI.

PURPOSE: This study aims to determine the degree of shared decision-making (SDM) from urological patients' perspective and to identify possible predictors. METHODS: Overall, 469 urological patients of a university outpatient clinic were recruited for this prospective study. Before a medical consultation, clinical and sociodemographic information, and patients' emotional distress were assessed by questionnaires. After the consultation, patients completed the SDM-Questionnaire-9 (SDM-Q-9). The SDM-Q-9 scores of relevant subgroups were compared. Logistic regression was used to identify patients at risk for experiencing low involvement (SDM-Q-9 total score ≤ 66) in SDM. RESULTS: Data from 372 patients were available for statistical analyses. The SDM-Q-9 mean total score was 77.8 ± 20.6. The majority of patients (n = 271, 73%) experienced a high degree of involvement (SDM-Q-9 total score > 66). The mean score per SDM-Q-9 item was in the upper range (3.9 ± 1.4 out of 5). The most poorly rated item was "My doctor wanted to know how I want to be involved in decision-making" (3.5 ± 1.6). Immigration status (OR 3.7, p = 0.049), and nonscheduled hospital registration (OR 2.1, p = 0.047) were significant predictors for less perceived involvement. Comorbidity, oncological status, and emotional distress did not significantly predict perceived participation. CONCLUSION: In a university hospital setting, most urological patients feel adequately involved in SDM. Nevertheless, urologists should routinely ask for patients' participation preference. Patients without a scheduled appointment and patients who immigrated may need more support to feel involved in SDM.

BACKGROUND: Real-time multispectral imaging (rMSI) simultaneously provides white light (WL), photodynamic diagnosis (PDD) images, and a real-time fusion of both. It may improve the detection of bladder tumors. However, rMSI has not been used for transurethral biopsy or resection so far. The aim of this ex vivo study was to test the feasibility of bladder tumor biopsies using the rMSI system and compare it to a conventional endoscopic system. METHODS: A 3D printed rigid bladder phantom was equipped with small and flat (5 mm × 1 mm) mock-bladder-tumors made of silicone and fluorescent Qdots655 (Thermo Fisher Scientific, Germany). Urologists (n=15) were asked to perform a rigid cystoscopy and biopsy of all identified lesions (n=6) using a prototype rMSI system and the Image1 S system (Karl Storz, Tuttlingen). Success rate and completion time were measured. The image quality of both systems and the usability of the rMSI system according to the system usability scale (SUS) were evaluated with a task-specific questionnaire. RESULTS: Tumor detection and biopsy rate were 100% (90/90) for the rMSI system and 98.9% (89/90) for the Image1 S system (P=0.3). The biopsy completion time did not differ significantly between the systems (P=0.48). Differentiation between healthy and suspect mucosa with the rMSI system was rated as comparable to the Image1 S system by 53% of surgeons and as better by 33% of the surgeons. The median SUS score for the rMSI system was 87.5%. CONCLUSIONS: Accurate transurethral biopsies are feasible with the rMSI system. Furthermore, the rMSI system has an excellent SUS. This study paves the way to the first in-human transurethral resections of bladder tumors (TUR-B) using rMSI technology.
