Real-world performance of Uromonitor® in urothelial bladder cancer detection: a multicentric trial.

OBJECTIVES: To compare Uromonitor® (U-Monitor Lda, Porto, Portugal), a multitarget DNA assay that detects mutated proto-oncogenes (telomerase reverse transcriptase [TERT], fibroblast growth factor receptor 3 [FGFR-3], Kirsten rat sarcoma viral oncogene homologue [KRAS]), with urine cytology in the urine-based diagnosis of urothelial carcinoma of the bladder (UCB) within a multicentre real-world setting. PATIENTS AND METHODS: This multicentre, prospective, double-blind study was conducted across four German urological centres from 2019 to 2024. We evaluated the diagnostic performance of Uromonitor compared to urine cytology in a cohort of patients with UCB and in healthy controls within a real-world setting. Sensitivity, specificity, positive-predictive value (PPV), negative-predictive value (NPV), and accuracy of the tests were measured, in addition to multivariate analyses to assess the ability of individual proto-oncogene mutations in detecting UCB. The biometric sample size was designed to achieve a 10% difference in sensitivity. RESULTS: Patients with UCB comprised 63.7% (339/532) of the study group. Uromonitor showed a sensitivity, specificity, PPV, NPV, accuracy, and an area-under-the-curve of 49.3%, 93.3%, 92.8%, 51.1%, 65.2%, and 0.713%, respectively. These metrics did not demonstrate statistical superiority over urine cytology in terms of sensitivity (44.6%; P = 0.316). Moreover, the comparison of additional test parameters, as well as the comparison within various sensitivity analyses, yielded no significant disparity between the two urinary tests. Multivariate logistic regression underscored the significant predictive value of a positive Uromonitor for detecting UCB (odds ratio [OR] 9.03; P < 0.001). Furthermore, mutations in TERT and FGFR-3 were independently associated with high odds of UCB detection (OR 13.30 and 7.04, respectively), while KRAS mutations did not exhibit predictive capability. CONCLUSION: Despite its innovative approach, Uromonitor fell short of confirming the superior results anticipated from previous studies in this real-world setting. The search for an optimal urine-based biomarker for detecting and monitoring UCB remains ongoing. Results from this study highlight the complexity of developing non-invasive diagnostic tools and emphasise the importance of continued research efforts to refine these technologies.

Integrating tumor and healthy epithelium in a micro-physiology multi-compartment approach to study renal cell carcinoma pathophysiology.

The advent of micro-physiological systems (MPS) in biomedical research has enabled the introduction of more complex and relevant physiological into in vitro models. The recreation of complex morphological features in three-dimensional environments can recapitulate otherwise absent dynamic interactions in conventional models. In this study we developed an advanced in vitro Renal Cell Carcinoma (RCC) that mimics the interplay between healthy and malignant renal tissue. Based on the TissUse Humimic platform our model combines healthy renal proximal tubule epithelial cells (RPTEC) and RCC. Co-culturing reconstructed RPTEC tubules with RCC spheroids in a closed micro-perfused circuit resulted in significant phenotypical changes to the tubules. Expression of immune factors revealed that interleukin-8 (IL-8) and tumor necrosis factor-alfa (TNF-α) were upregulated in the non-malignant cells while neutrophil gelatinase-associated lipocalin (NGAL) was downregulated in both RCC and RPTEC. Metabolic analysis showed that RCC prompted a shift in the energy production of RPTEC tubules, inducing glycolysis, in a metabolic adaptation that likely supports RCC growth and immunogenicity. In contrast, RCC maintained stable metabolic activity, emphasizing their resilience to external factors. RNA-seq and biological process analysis of primary RTPTEC tubules demonstrated that the 3D tubular architecture and MPS conditions reverted cells to a predominant oxidative phosphorylate state, a departure from the glycolytic metabolism observed in 2D culture. This dynamic RCC co-culture model, approximates the physiology of healthy renal tubules to that of RCC, providing new insights into tumor-host interactions. Our approach can show that an RCC-MPS can expand the complexity and scope of pathophysiology and biomarker studies in kidney cancer research.

Urine-Based Biomarker Test Uromonitor® in the Detection and Disease Monitoring of Non-Muscle-Invasive Bladder Cancer-A Systematic Review and Meta-Analysis of Diagnostic Test Performance.

Optimal urine-based diagnostic tests (UBDT) minimize unnecessary follow-up cystoscopies in patients with non-muscle-invasive bladder-cancer (NMIBC), while accurately detecting high-grade bladder-cancer without false-negative results. Such UBDTs have not been comprehensively described upon a broad, validated dataset, resulting in cautious guideline recommendations. Uromonitor®, a urine-based DNA-assay detecting hotspot alterations in TERT, FGFR3, and KRAS, shows promising initial results. However, a systematic review merging all available data is lacking. Studies investigating the diagnostic performance of Uromonitor® in NMIBC until November 2023 were identified in PubMed, Embase, Web-of-Science, Cochrane, Scopus, and medRxiv databases. Within aggregated analyses, test performance and area under the curve/AUC were calculated. This project fully implemented the PRISMA statement. Four qualifying studies comprised a total of 1190 urinary tests (bladder-cancer prevalence: 14.9%). Based on comprehensive analyses, sensitivity, specificity, positive-predictive value/PPV, negative-predictive value/NPV, and test accuracy of Uromonitor® were 80.2%, 96.9%, 82.1%, 96.6%, and 94.5%, respectively, with an AUC of 0.886 (95%-CI: 0.851-0.921). In a meta-analysis of two studies comparing test performance with urinary cytology, Uromonitor® significantly outperformed urinary cytology in sensitivity, PPV, and test accuracy, while no significant differences were observed for specificity and NPV. This systematic review supports the use of Uromonitor® considering its favorable diagnostic performance. In a cohort of 1000 patients with a bladder-cancer prevalence of ~15%, this UBDT would avert 825 unnecessary cystoscopies (true-negatives) while missing 30 bladder-cancer cases (false-negatives). Due to currently limited aggregated data from only four studies with heterogeneous quality, confirmatory studies are needed.

The landscape of penile cancer research in Germany and Austria: a survey among professors in academic centers holding chair positions and results of a literature search.

BACKGROUND: Research on penile cancer (PeCa) is predominantly conducted in countries with centralized treatment of PeCa-patients. In Germany and Austria (G + A), no state-regulated centralization is established, and no information is available on how PeCa-research is organized. METHODS: Current research competence in PeCa was assessed by a 36-item questionnaire sent to all chairholders of urological academic centers in G + A. Based on PubMed records, all scientific PeCa-articles of 2012-2022 from G + A were identified. Current research trends were assessed by dividing the literature search into two periods (P1: 2012-2017, P2: 2018-2022). A bibliometric analysis was supplemented. RESULTS: Response rate of the questionnaire was 75%, a median of 13 (IQR: 9-26) PeCa-patients/center was observed in 2021. Retrospective case series were conducted by 38.9% of participating clinics, while involvement in randomized-controlled trials was stated in 8.3% and in basic/fundamental research in 19.4%. 77.8% declared an interest in future multicenter projects. 205 PeCa-articles were identified [median impact factor: 2.77 (IQR: 0.90-4.37)]. Compared to P1, P2 showed a significant increase in the median annual publication count (29 (IQR: 13-17) vs. 15 (IQR: 19-29), p < 0.001), in multicenter studies (79.1% vs. 63.6%, p = 0.018), and in multinational studies (53% vs. 28.9%, p < 0.001); the proportion of basic/fundamental research articles significantly declined (16.5% vs. 28.9%, p = 0.041). Four of the top-5 institutions publishing PeCa-articles are academic centers. Bibliometric analyses revealed author networks, primary research areas in PeCa, and dominant journals for publications. CONCLUSIONS: Given the lack of centralization in G + A, this analysis highlights the need for research coordination within multicenter PeCa-projects. The decline in basic/fundamental research should be effectively addressed by the allocation of funded research projects.

Impact of Peritoneal Interposition Flap on Patients Undergoing Robot-assisted Radical Prostatectomy and Pelvic Lymph Node Dissection: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

CONTEXT: Symptomatic lymphocele (sLC) occurs at a frequency of 2-10% after robot-assisted radical prostatectomy (RARP) with pelvic lymph node dissection (PLND). Construction of bilateral peritoneal interposition flaps (PIFs) subsequent to completion of RARP + PLND has been introduced to reduce the risk of lymphocele, and was initially evaluated on the basis of retrospective studies. OBJECTIVE: To conduct a systematic review and meta-analysis of only randomized controlled trials (RCTs) evaluating the impact of PIF on the rate of sLC (primary endpoint) and of overall lymphocele (oLC) and Clavien-Dindo grade ≥3 complications (secondary endpoints) to provide the best available evidence. EVIDENCE ACQUISITION: In accordance with the Preferred Reporting Items for Meta-Analyses statement for observational studies in epidemiology, a systematic literature search using the MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), and EMBASE databases up to February 3, 2023 was performed to identify RCTs. The risk of bias (RoB) was assessed using the revised Cochrane RoB tool for randomized trials. Meta-analysis used random-effect models to examine the impact of PIF on the primary and secondary endpoints. EVIDENCE SYNTHESIS: Four RCTs comparing outcomes for patients undergoing RARP + PLND with or without PIF were identified: PIANOFORTE, PerFix, ProLy, and PLUS. PIF was associated with odds ratios of 0.46 (95% confidence interval [CI] 0.23-0.93) for sLC, 0.51 (95% CI 0.38-0.68) for oLC, and 0.41 (95% CI 0.21-0.83) for Clavien-Dindo grade ≥3 complications. Functional impairment resulting from PIF construction was not observed. Heterogeneity was low to moderate, and RoB was low. CONCLUSIONS: PIF should be performed in patients undergoing RARP and simultaneous PLND to prevent or reduce postoperative sLC. PATIENT SUMMARY: A significant proportion of patients undergoing prostate cancer surgery have regional lymph nodes removed. This part of the surgery is associated with a risk of postoperative lymph collections (lymphocele). The risk of lymphocele can be halved via a complication-free surgical modification called a peritoneal interposition flap.

Patient Benefits of Radical Prostatectomy in Certified Prostate Cancer Centers: Comparative Results from the Multicenter IMPROVE Study.

INTRODUCTION: We investigated differences in treatment outcomes following radical prostatectomy (RP) between certified centers (CCs) and noncertified centers (nCCs) within the IMPROVE study group. METHODS: A validated survey assessing various factors, including stress urinary incontinence (SUI) and decision regret (DR), was administered to 950 patients who underwent RP across 19 hospitals (12 CCs and 7 nCCs) at a median follow-up of 15 months after RP (interquartile range: 11-20). The response rate was 74%, with 703 patients participating, including 480 (68%) from CCs. Multivariate binary regression models were used to analyze differences between CCs and nCCs regarding the following binary endpoints: nerve-sparing (NS), positive surgical margins (PSM), SUI (defined as >1 safety pad), complications based on the Clavien-Dindo classification (grade ≥1, grade ≥3) and DR (>15 points indicating critical DR). RESULTS: Considering the multivariate analysis, the rate of NS surgery was lower in CCs than in nCCs (OR = 0.52; p = 0.004). No significant differences were observed in the PSM rate (OR = 1.67; p = 0.051), SUI (OR = 1.03; p = 0.919), and DR (OR = 1.00; p = 0.990). SUI (OR 0.39; p < 0.001) and DR (OR 0.62; p = 0.026) were reported significantly less frequently by patients treated with robotic-assisted RP, which was significantly more often performed in CCs than in nCCs (68.3% vs. 18%; p < 0.001). The total complication rate was 45% lower in CCs (OR = 0.55; p = 0.004), although the number of complications requiring intervention (Clavien-Dindo classification ≥3) did not differ significantly between CCs and nCCs (OR = 2.52; p = 0.051). CONCLUSION: Within the IMPROVE study group, similarly favorable outcomes after RP were found in both CCs and nCCs, which, however, cannot be transferred to the general treatment landscape of PCA in Germany. Of note, robotic-assisted RP was more often performed in CCs and associated with less SUI and DR, while open prostatectomy was the treatment of choice in low-volume nCCs. Future prospective and region wide studies should also investigate the surgeon caseload and experience as well as a spillover effect of the certification process on nCCs.

Centralizing Penile Cancer Care in Germany and Austria: Just a Dream or a Fast-Approaching Reality? Results of a Survey Study among Urological Department Chairs and Modeling of Real Treatment Numbers of Penile Cancer Patients.

INTRODUCTION: In countries characterized by a centralization of therapy management, patients with penile cancer (PeCa) have shown improvements in guideline adherence and ultimately, improved carcinoma-specific survival. Germany and Austria (G + A) have no state-regulated centralization of PeCa management, and the perspectives of urological university department chairs (UUDCs) in these countries, who act as drivers of professional and political developments, on this topic are currently unknown. METHODS: Surveys containing 36 response options, including specific questions regarding perspectives on PeCa centralization, were sent to the 48 UUDC in G + A in January 2023. In addition to analyzing the responses, closely following the CROSS checklist, a modeling of the real healthcare situation of in-house PeCa patients in G + A was conducted. RESULTS: The response rate was 75% (36/48). 94% and 89% of the UUDCs considered PeCa centralization meaningful and feasible in the medium term, respectively. Among the UUDCs, 72% estimated centralization within university hospitals as appropriate, while 28% favored a geographically oriented approach. Additionally, 97% of the UUDCs emphasized the importance of bridging the gap until implementation of centralization by establishing PeCa second-opinion portals. No country-specific differences were observed. The median number of in-house PeCa cases at the university hospitals in G + A was 13 (interquartile range: 9-26). A significant positive correlation was observed between the annual number of in-house PeCa cases at a given university hospital and the perspective of the UUDCs that centralization as meaningful by its UUDC (0.024). Under assumptions permissible for modeling, the average number of in-house PeCa cases in academic hospitals in G + A was approximately 30 times higher than in nonacademic hospitals. CONCLUSION: This study provides the first data on the perspectives of UUDCs in G + A concerning centralization of PeCa therapy management. Even without state-regulated centralization in G + A, there is currently a clear focusing of PeCa treatments in university hospitals. Further necessary steps toward a structured PeCa centralization are discussed in this manuscript.

Patient's Desire and Real Availability Concerning Supportive Measures Accompanying Radical Prostatectomy: Differences between Certified Prostate Cancer Centers and Non-Certified Centers Based on Patient-Reported Outcomes within the Cross-Sectional Study Improve.

Certification as a prostate cancer center requires the offer of several supportive measures to patients undergoing radical prostatectomy (RP). However, it remains unclear how patients estimate the relevance of these measures and whether the availability of these measures differs between certified prostate cancer centers (CERTs) and non-certified centers (NCERTs). In 20 German urologic centers, a survey comprising questions on the relevance of 15 supportive measures was sent to 1000 patients at a median of 15 months after RP. Additionally, patients were asked to rate the availability of these measures using a four-item Likert scale. The aim of this study was to compare these ratings between CERTs and NCERTs. The response rate was 75.0%. In total, 480 patients underwent surgery in CERTs, and 270 in NCERTs. Patients rated 6/15 supportive measures as very relevant: preoperative medical counselling concerning treatment options, a preoperative briefing answering last questions, preoperative pelvic floor exercises (PFEs), postoperative PFEs, postoperative social support, and postoperative rehabilitation addressing physical fitness recovery. These ratings showed no significant difference between CERTs and NCERTs (p = 0.133-0.676). In addition, 4/9 of the remaining criteria were rated as more detailed by patients in CERTs. IMPROVE represents the first study worldwide to evaluate a patient-reported assessment of the supportive measures accompanying RP. Pertinent offers vary marginally between CERTs and NCERTs.

[Are there any volume-related effects on treatment options for patients with penile cancer? Results of a survey among university hospitals in Germany and Austria]. / Gibt es fallzahlabhängige Effekte auf Behandlungsangebote für Patienten mit einem Peniskarzinom? Ergebnisse einer Umfrage an Universitätsklinika in Deutschland und Österreich.

BACKGROUND: Currently, 959 men in Germany and 67 in Austria are diagnosed with penile cancer each year, with an increase of approximately 20% in the last decade [RKI 2021, Statcube.at 2023]. Despite the rising incidence, the number of cases per hospital remains low. The median annual number of penile cancer cases at university hospitals in the DACH region was 7 patients (IQR 5-10) in 2017 [E-PROPS group 2021]. The compromised institutional expertise due to low case numbers is compounded with inadequate adherence to penile cancer guidelines, as shown in several studies. The centralization, which is rigorously implemented in countries such as the UK, enabled a significant increase in organ-preserving primary tumor surgery and stage-adapted lymphadenectomies, as well as improved patient survival in cases of penile cancer, resulting in a claim for a similar centralization in Germany and Austria. The aim of this study was to determine the current effects of case volume on penile cancer related treatment options at university hospitals in Germany and Austria. MATERIALS AND METHODS: In January 2023, a survey was sent to the heads of 48 urological university hospitals in Germany and Austria, including questions regarding case volume in 2021 (total number of inpatient and penile cancer cases), treatment options for primary tumors and inguinal lymphadenectomy (ILAE), the availability of a designated penile cancer surgeon, and the professional responsibility for systemic therapies in penile cancer. Correlations and differences related to case volume were statistically analyzed without adjustments. RESULTS: The response rate was 75% (n=36/48). In total, 626 penile cancer patients were treated at the 36 responding university hospitals in 2021, representing approximately 60% of the expected incidence in Germany and Austria. The annual median total number of cases was 2807 (IQR 1937-3653), and for penile cancer, it was 13 (IQR 9-26). There was no significant correlation between the total inpatient and penile cancer caseloads (p=0.34). The number of organ-preserving therapy procedures for the primary tumor, the availability of modern ILAE procedures, the presence of a designated penile cancer surgeon, and the responsibility for systemic therapies were not significantly influenced by the total inpatient or penile cancer case volume of the treating hospitals, regardless of whether the case volumes were dichotomized at the median or upper quartile. No significant differences between Germany and Austria were observed. CONCLUSION: Despite a significant increase in the annual number of penile cancer cases at university hospitals in Germany and Austria compared to 2017, we found no case volume-related effects on structural quality with respect to penile cancer therapy. In the light of the proven benefits of centralization, we interpret this result as an argument for the necessity of establishing nationally organized penile cancer centers with even higher case volumes compared to the status quo, in light of the proven benefits of centralization.

Diagnosis of female urethral diverticulum using pelvic floor ultrasound and comparison with voiding cystourethrogram (imaging study).

INTRODUCTION AND HYPOTHESIS: The purpose of this study was to evaluate the sensitivity and specificity of pelvic floor ultrasound (PFUS) in the diagnostic work-up of female urethral diverticulum (UD) and to compare results of PFUS with voiding cystourethrogram (VCUG). METHODS: We retrospectively reviewed our database of patients, who received VCUG and PFUS for the diagnosis of UD. A total of 196 consecutive female patients with a minimum of one symptom, such as a lower urinary tract symptom (LUTS), postmicturition dribble, dyspareunia and recurrent urinary tract infection (UTI) who underwent initial diagnostics with VCUG and PFUS were selected. Diagnostic performance of both procedures, which included size, complexity, echogenicity. and content were compared. RESULTS: Recurrent UTI and LUTS were the most common symptoms, which were present in 165 (84%) and 163 patients (83%) respectively. Final diagnosis of UD was based on PFUS and VCUG findings in 69 (35%) and 58 (30%) cases respectively. Based on our study cohort, the sensitivity of PFUS in detecting UD was significantly higher than that of VCUG: 94% (IQR: 89-97) versus 78% (IQR: 73-85, p<0.01), with a trend toward higher specificity: 100% (IQR: 94-100) versus 84% (IQR: 78-84, p=0.05). Enabling direct UD visualisation, PFUS was associated with a positive predictive value (PPV) of 100% (IQR: 97-100) and a negative predictive value (NPV) of 88% (IQR: 78-95), whereas VCUG had an inferior accuracy with a PPV of 84 (IQR: 80-84) and a NPV of 68 (IQR: 62-79). CONCLUSIONS: In clinical practice, VCUG has a lower sensitivity than PFUS. Based on these results, we recommend the usage of dynamic PFUS as part of a non-invasive work-up.

Patients Regret Their Choice of Therapy Significantly Less Frequently after Robot-Assisted Radical Prostatectomy as Opposed to Open Radical Prostatectomy: Patient-Reported Results of the Multicenter Cross-Sectional IMPROVE Study.

Patient's regret (PatR) concerning the choice of therapy represents a crucial endpoint for treatment evaluation after radical prostatectomy (RP) for prostate cancer (PCA). This study aims to compare PatR following robot-assisted (RARP) and open surgical approach (ORP). A survey comprising perioperative-functional criteria was sent to 1000 patients in 20 German centers at a median of 15 months after RP. Surgery-related items were collected from participating centers. To calculate PatR differences between approaches, a multivariate regressive base model (MVBM) was established incorporating surgical approach and demographic, center-specific, and tumor-specific criteria not primarily affected by surgical approach. An extended model (MVEM) was further adjusted by variables potentially affected by surgical approach. PatR was based on five validated questions ranging 0−100 (cutoff >15 defined as critical PatR). The response rate was 75.0%. After exclusion of patients with laparoscopic RP or stage M1b/c, the study cohort comprised 277/365 ORP/RARP patients. ORP/RARP patients had a median PatR of 15/10 (p < 0.001) and 46.2%/28.1% had a PatR >15, respectively (p < 0.001). Based on the MVBM, RARP patients showed PatR >15 relative 46.8% less frequently (p < 0.001). Consensual decision making regarding surgical approach independently reduced PatR. With the MVEM, the independent impact of both surgical approach and of consensual decision making was confirmed. This study involving centers of different care levels showed significantly lower PatR following RARP.

In Vitro Characterization of Renal Drug Transporter Activity in Kidney Cancer.

The activity of drug transporters is central to the secretory function of the kidneys and a defining feature of renal proximal tubule epithelial cells (RPTECs). The expression, regulation, and function of these membrane-bound proteins is well understood under normal renal physiological conditions. However, the impact of drug transporters on the pathophysiology of kidney cancer is still elusive. In the present study, we employed different renal cell carcinoma (RCC) cell lines and a prototypical non-malignant RPTEC cell line to characterize the activity, expression, and potential regulatory mechanisms of relevant renal drug transporters in RCC in vitro. An analysis of the uptake and efflux activity, the expression of drug transporters, and the evaluation of cisplatin cytotoxicity under the effects of methylation or epidermal growth factor receptor (EGFR) inhibition showed that the RCC cells retained substantial drug transport activity. In RCC cells, P-glycoprotein was localized in the nucleus and its pharmacological inhibition enhanced cisplatin toxicity in non-malignant RPTECs. On the other hand, methylation inhibition enhanced cisplatin toxicity by upregulating the organic cation uptake activity in RCC cells. Differential effects of methylation and EGFR were observed in transporter expression, showing regulatory heterogeneity in these cells. Interestingly, the non-malignant RPTEC cell line that was used lacked the machinery responsible for organic cation transport, which reiterates the functional losses that renal cells undergo in vitro.

[Impact of the experience of urological senior physicians in Germany on professional and personal aspects]. / Welchen Einfluss hat die Dauer der Oberarzttätigkeit auf die Berufsausübung und Zufriedenheit urologischer OberärztInnen in Deutschland?

BACKGROUND: Urological senior physicians in Germany are a heterogeneous group with various clinical priorities and career objectives. To date, there are no reliable data concerning the impact of the time span for which senior physicians have been holding their position on professional, personal and position-linked aspects. MATERIAL AND METHODS: The objective of this study was a comparative analysis of perspectives, private and professional settings, specific job-related activities and individual professional goals of urological senior physicians in Germany based on their experience in this position assessed as number of years (dichotomised at 8 years as senior physician). As part of a cross-sectional study, a 55-item web-based questionnaire was designed, which was sent via a link to members of a mailing list of the German Society of Urology. The survey was available for urological senior physicians between February and April 2019. Group differences were evaluated using multivariate regression models. RESULTS: 107 of 192 evaluable questionnaires were completed by senior physicians holding this position for less than 8 years (< 8y senior physicians), 85 were completed by senior physicians holding this position for at least 8 years (≥ 8y senior physicians). < 8y senior physicians worked significantly more often at university hospitals (42.1 % vs. 18.8 %, p = 0.002). Overall, 82.4 % of ≥ 8y senior physicians assessed themselves autonomously safe in performing open surgery, compared to 39.3 % among < 8y senior physicians (p < 0.001). No significant differences concerning the self-assessment were found for endourological procedures (94.1 % vs. 87.9 %) and for the overall lower-rated self-assessment concerning laparoscopy (29.4 % vs. 20.6 %) and robotic surgery (14.1 % vs. 10.3 %). Despite the high management responsibility associated with their position, only about one third of participants (34.8 %) had received specific postgraduate education preparing them for managing and executive tasks. CONCLUSION: This study shows significant differences among senior physicians regarding surgical skills depending on the time span they hold their position. Moreover, there is considerable dissatisfaction regarding the development of leadership skills and the preparation for managing tasks. In order to ensure availability of senior staff members for the field of urology in the future, it is important to consider their professional needs and to overcome existing shortcomings by education programs within well-orchestrated human resources development strategies.

[Knowledge of German-speaking urologists regarding the association between penile cancer and human papilloma virus: results of a survey of the European PROspective Penile Cancer Study (E-PROPS)]. / Kenntnisse von deutschsprachigen Urologen zur Häufigkeit der Assoziation des Peniskarzinoms mit dem Humanen Papillomavirus ­ Survey-Ergebnisse der European PROspective Penile Cancer Study (E-PROPS).

BACKGROUND: A recent meta-analysis showed that penile cancer (PeC) is associated with the human papilloma virus (HPV) in 50 % of patients in Europe. It is unknown whether urologists are aware of the impact of viral carcinogenesis. METHODS: A (German-language) survey comprising 14 items was created and sent to urologists of 45 clinical centres in Germany (n = 34), Austria (n = 8), Switzerland (n = 2) and Italy/South Tyrol (n = 1) once in Q3/2018. According to a predefined quality standard, a total of 557 surveys were eligible for final data analysis (response rate: 85.7 %). Among other questions, urologists were asked to state the frequency of HPV-associated PeC in Europe. 4 potential answers were provided: (A)-"< 25 %", (B)-"25 - 50 %", (C)-"> 50 - 75 %", (D)-"level of association unknown". For the final calculation, a tolerance of ±â€Š50 % was considered acceptable, so B and C were deemed correct answers. Based on a bootstrap-adjusted multivariate logistic regression model, criteria independently predicting a correct answer were identified. RESULTS: Categories A-D were selected in 19.2 % (n = 107), 48.8 % (n = 272), 12.9 % (n = 72) and 19 % (n = 106), respectively, representing a rate of 61.8 % of urologists (n = 344) reaching the endpoint (B + C). Autonomous performance of chemotherapy for PeC by urologists within the given centre (OR 1.55, p[Bootstrap] = 0.036) and the centre's number of urological beds (OR 1.02, p[Bootstrap] = 0.025) were the only parameters showing a significant independent impact on the endpoint. In contrast, the status of a university centre (p = 0.143), a leading position of the responding urologist (p = 0.375) and the number of PeC patients treated per year and centre (p = 0.571) did not significantly predict a correct answer. CONCLUSIONS: Our results demonstrate insufficient knowledge on the association of PeC and HPV among German-speaking urologists.
