Genital gender-affirming surgery trends in Germany: Total population data with 19,600 cases from 2006 to 2022.

PURPOSE: To delineate the current trends regarding gender-affirming surgeries (GAS) in Germany. METHODS: Analysis of German hospital quality reports from 2006 to 2022 was conducted using the reimbursement.info tool. The German procedure classification (OPS) codes 5-646.0 for masculinizing- and 5-646.1 for feminizing surgery were assessed to identify GAS. Linear regression models were utilized for the analysis and depiction of current trends. RESULTS: A total of 19,632 gender-affirming procedures were performed during the study period with an exponential increase over the years. Masculinizing surgeries increased from 246 in 2006 to 1291 cases in 2022 (increase by 424%; p < 0.001). The highest annual increase of 37.2% in numbers was from 2018 to 2019 (from 1235 to 1694 cases). Feminizing surgeries increased from 180 cases in 2006 to 799 procedures in 2022 (increase by 343%; p < 0.001). The cases increased most between 2015 and 2016 from 277 to 502 cases (81.2%). The number of hospitals offering these surgeries expanded from 24 in 2006 to 29 in 2022 (21% increase; p < 0.001). CONCLUSION: This study demonstrates an exponential growth in numbers feminizing and masculinizing of GAS performed each year in Germany. Furthermore, a discernible trend emerges with a propensity for concentration of procedures within selected high-caseload centers across Germany.

[Knowledge about human papillomaviruses among students in Germany-a cross-sectional study with a need for action]. / Wissen über humane Papillomaviren unter Studierenden in Deutschland: eine Querschnittstudie belegt dringenden Handlungsbedarf.

BACKGROUND AND OBJECTIVES: The human papillomavirus (HPV) is one of the most common viruses transmitted through intimate contact, causing many benign and malignant diseases. Vaccination protects against these diseases. Despite the HPV vaccination being recommended by the Standing Committee on Vaccination (STIKO), knowledge and vaccination rates in Germany are very low. Therefore, the aim of the study was to assess the HPV knowledge among German students. MATERIALS AND METHODS: Between 06/2019 and 01/2024, a nationwide online survey on HPV knowledge among students in Germany was distributed via the respective student councils. The survey included two aspects: 1) basic characteristics of the participants and 2) knowledge questions about HPV (e.g., transmission routes, effectiveness, and side effects of vaccination, knowledge about the HPV subtypes). Data collection was anonymous. RESULTS: A total of 459 students took part in the study. Of these, 335 (72.98%) were female, 122 (26.57%) were male, and 2 (0.45%) did not specify their gender. The average age of the students was 24.02 years, and most of the participants were in their 6th (23.31%/107) semester. In all, 75.82% (348) of the participants were medical students followed by law students with 19.61% (90) participants. The most represented study location was Aachen, with 270 (58.82%) participants. Only about half (48.80%/223) of the students knew that approximately 8000 new cancer cases in Germany are HPV-associated annually. Regarding the HPV vaccination, more than a third (35.82%/163) of participants did not know that it also protects against genital warts, while 21.93% (100) did not know that boys can also benefit from the HPV vaccination and that it does not only improve HPV protection of girls against cervical cancer. CONCLUSION: Despite several years of HPV vaccination recommendation by the Standing Committee on Vaccination (STIKO), knowledge about HPV among college students still remains very low. Further prevention and educational efforts are needed to address HPV knowledge gaps, with the additional goal of improving HPV vaccination rates.

Urologist communication is a primary factor leading to erectile dysfunction treatment postprostatectomy.

BACKGROUND: Studies have shown insufficient utilization of care for patients with erectile dysfunction (ED) after radical prostatectomy (RP). AIM: The aim of this study was to evaluate variables associated with barriers to seeking and receiving ED treatment. METHODS: In this multicenter prospective cross-sectional study, the functional outcomes of 936 patients were assessed 10 to 15 years after RP. A total of 525 patients with ED or incontinence were asked about their treatment experiences or lack thereof. The data were analyzed using the chi-square test, t test, and multivariate logistic analyses. OUTCOMES: Patients answered validated questionnaires regarding information sources, communication with their partner and urologist, and barriers to ED treatment. RESULTS: Of the 525 patients, 80 were not available to survey. A total of 304 patients answered the survey (response: 68.0%). A total of 246 patients had ED and were included in this study. The mean age at surgery was 64.4 ± 6.1 years, and the mean age at the time of this survey was 77.1 ± 6.2 years. The mean follow-up duration was 12.7 ± 1.5 years. Forty-six percent (n = 114 of 246) of the patients had never received ED treatment. The most important conversation partners regarding the ED were the partner (69% [n = 169 of 246]) and the urologist (48% [n = 118 of 246]). Patients who never received ED treatment were less likely to have conversations with their urologist (34% vs 60%; P < .001), had less support (51% vs 68%; P = .01), and had less interest in sex from their partner (20% vs 40%; P = .001). Communication with other groups (general practitioners, other physicians, family, friends, and the Internet) had no influence on ED treatment utilization. The most relevant barrier to receiving ED treatment was the belief that treatment would not help (65%). No interest in sex from their partner (odds ratio, 3.9) and no conversation with their urologist about ED (odds ratio, 2.9) were found to be independent predictors of not receiving ED treatment. CLINICAL IMPLICATIONS: Urologists should have enhanced awareness of how to approach patients directly about their ED and actively offer them treatment options. STRENGTHS AND LIMITATIONS: These results should be further validated in a multicenter, prospective study. Response bias may have affected the results. Furthermore, the current cohort was relatively old. CONCLUSION: This study revealed that no interest in sex from one's partner and insufficient communication with a urologist were relevant barriers to insufficient utilization of ED treatment after RP.

Declining utilization of urodynamic studies in urological care in Germany: time to say goodbye?

INTRODUCTION: The number of urodynamic studies (UDS) has been declining steadily in recent decades, yet the reasons behind this trend remain poorly understood. This study aims to investigate the structural aspects of UDS in urology and explore the factors contributing to this decline. MATERIAL & METHODS: We surveyed all urological departments performing UDS as well as a representative sample of private practices in Germany in 2023. We examined structural situation, waiting times, capacities and limitations of UDS. All invasive urodynamic examinations were defined as UDS. RESULTS: In 2019, 259/474 (55%) urological departments in Germany performed UDS. 206/259 (80%) urological departments responded to the survey. 163/200 (82%) urological departments stated that their capacities were exhausted, a main reason being lack of medical and nursing staff. 54.8% urological departments performed more than 50% of their UDS for referring physicians. Urological departments with a low number of UDS/year (≤ 100) showed a shorter waiting time (up to 4 weeks: 49% vs. 30%; p = 0.01), reduced UDS capacities (55% vs. 12%; p < 0.001) and these capacities were often not fully utilized (25% vs. 9%; p = 0.007). 122/280 (44%) office urologists responded to the survey. 18/122 (15%) office urologists performed UDS. Main reasons for not offering UDS were lack of personnel and low reimbursement. CONCLUSION: In German urological departments, UDS capacities are consistently fully utilized, primarily due to staffing shortages. This trend towards centralization prompts questions about the role of UDS in urologists' training.

Treatment trends for undescended testis and impact of guideline changes a medical health care analysis of orchidopexy and cryptorchidism in Germany between 2006 und 2020.

BACKGROUND: The last decades revealed new scientific knowledge regarding the fertility and potential malignancy of undescended testis AQ2(UDT). Accordingly, many guidelines changed their recommendation concerning timing of therapy, with the goal of an earlier time of surgery. METHODS: We analyzed the number of new diagnosis and performed surgeries in predefined age groups provided by the obligatory annual reports of German hospitals in the reimbursement.INFO"-tool between 2006 and 2020. RESULTS: Overall, 124,741 cases were analyzed. We showed a slight increase in performed surgeries in the first year by 2% per year with a main increase till 2011, a constant number of surgeries between first and 4th year and a decrease of surgeries between 5 and 14th year of living with a main decrease till 2009 by 3% per year. CONCLUSION: Even if our results illustrate an increasing adaption of the guideline's recommendation, there is still a significant number of patients who receive later treatment. More research about the reasons and circumstances for the latter is needed.

Pilot study for bladder cancer detection with volatile organic compounds using ion mobility spectrometry: a novel urine-based approach.

PURPOSE: Despite many efforts, no reliable urinary marker system has so far shown the potential to substitute cystoscopy. Measuring volatile organic compounds (VOCs) from urine is a promising alternative. VOCs are metabolic products which can be measured from the headspace of urine samples. Previous studies confirmed that the urine of bladder tumor patients has a different VOC profile than healthy controls. In this pilot study, the feasibility of discriminating VOCs from urine of bladder cancer patients from that of healthy control subjects was investigated. Aim of this study was to investigate whether VOC-based diagnosis of bladder cancer from urine samples is feasible using multicapillary column ion mobility spectrometry (MCC/IMS) and to identify potential molecular correlates to the relevant analytes. METHODS: Headspace measurements of urine samples of 30 patients with confirmed transitional cell carcinoma (TCC) and 30 healthy controls were performed using MCC/IMS. In the results of the measurements, peaks showing significant differences between both groups were identified and implemented into a decision tree with respect to achieve group separation. Molecular correlates were predicted using a pre-defined dataset. RESULTS: Eight peaks with significantly differing intensity were identified, 5 of which were highly significant. Using a six-step decision tree, MCC/IMS showed a sensitivity of 90% and specificity of 100% in group separation. CONCLUSION: VOC-based detection of bladder cancer is feasible. MCC/IMS is a suitable method for urine-based diagnosis and should be further validated. The molecular characteristics and metabolic background of the analytes require further workup.

[Structural health care reality in the surgical treatment of male stress incontinence in Germany]. / Strukturelle Versorgungssituation der operativen Therapie bei männlicher Belastungsinkontinenz in Deutschland.

BACKGROUND: Stress urinary incontinence in men is predominantly iatrogenic after radical prostatectomy or transurethral interventions. Current studies show that there is a deficit in the availability of surgical therapy not only in Germany. The aim of this study is to investigate in more detail the structural health care situation of surgical treatment of male stress incontinence in Germany. MATERIALS AND METHODS: The evaluation of the surgical therapy of male stress incontinence in Germany is based on the OPS (Operationen- und Prozedurenschlüssel-German procedural classification) codes from hospital quality reports from 2011-2019. RESULTS: From 2012-2019, the number of male incontinence surgeries declined from 2191 to 1445. The number of departments performing incontinence surgeries decreased from 275 to 244. In the multivariate analysis, a high number (≥ 50) of radical prostatectomies/year (RPE/year) is an independent predictor of a high-volume centre (≥ 10 procedures/year; odds ratio [OR] 6.4 [2.3-17.6]; p < 0.001). The most significant decrease was in sling surgery (from 1091 to 410; p < 0.001). Here, the number of cases decreased especially in departments that implanted a high number of slings (≥ 10 slings/year; -69%; -62.4 ± 15.5 surgeries/year; p = 0.007). In addition, the number of departments implanting slings decreased over the investigated time period (from 34 to 10; p < 0.001). This particularly affected departments that also had a low number of RPE/year (from 9 to 0; -100%). CONCLUSION: The situation of surgical treatment of male stress urinary incontinence in Germany shows a clear decline in sling implantation, especially in small departments. On the one hand, this reflects the increasingly differentiated indications for sling implantation. On the other hand, it raises the suspicion that a gap in care has developed, as the decline was not compensated for by other surgical therapies.

Multicenter evaluation of complex urinary diversion for renal transplantation: outcomes of complex surgical solutions.

PURPOSE: An abnormal lower urinary tract poses significant challenges for transplant surgeons. Besides the ureteral anastomosis to an ileal conduit, there are diverse complex reconstructive solutions. Due to its rarity, standardization and teaching of complex urinary diversion is extremely difficult. METHODS: The indications and outcomes of complex urinary diversions after kidney transplantation (KT) were retrospectively investigated at eight urologic transplant centers including a current follow-up. RESULTS: Of 37 patients with 21 (56%) males, vesicoureteral reflux (24%), spina bifida (22%), and glomerulonephritis (12%) were the most common causes of terminal renal failure. In 30 (81%) patients, urinary diversion was performed before KT, at a median of 107.5 (range, 10; 545) months before. Transplantations were held at a median patient age of 43 (10; 68) years, including six (16%) living donations. Urinary diversion was modified during 12 (32%) transplantations. After KT, the ileal conduit was the most common incontinent urinary diversion in 25 (67%) patients; a Mainz pouch I and bladder augmentation were the most frequent continent diversions (each n = 3). At a median follow-up of 120 months (range 0; 444), 12 (32%) patients had a graft failure with a 5-year graft survival of 79% (95%CI 61; 90). The median overall survival was 227 months (168; 286) and the 5-year overall survival 89% (69.3; 96.4). CONCLUSION: The mid-term kidney transplant function with complex urinary diversion appears to be comparable to transplants with regular urinary diversions. Hence, complex urinary diversion should always be considered as a surgical option, even during transplantation, if necessary.

Online decision aid for patients with prostate cancer evaluated by 11 290 patients and 91 urologists in Germany.

OBJECTIVE: To evaluate the nationwide online decision aid 'Entscheidungshilfe Prostatakrebs' (established in 2016, >11.000 users and 60 new users/week) for patients with non-metastatic prostate cancer (PCa), from the perspective of patients and urologists. PATIENTS AND METHODS: To provide personalised information, the tool collects most of the International Consortium for Health Outcomes Measurement standard set, personal preferences, psychological features, and a validated rating of the tool. To evaluate urologists' opinions, we developed a structured two-page questionnaire. All data were collected anonymously. RESULTS: From June 2016 to December 2020, 11 290 patients used the PCa decision aid. Their median (interquartile range [IQR]) age was 67 (61-72) years. The median (IQR) time from initial diagnosis to using the tool was 4 (3-7) weeks. In all, 87.7% of users reported high satisfaction. In a multivariable model, predictors for considering observation were higher knowledge, using the decision aid alone, lower oncological risk, normal erectile function, and respective personal preferences. Of 194 urologists, 91 (47%) had implemented the decision aid in their clinical practice. The urologists' mean (SD) satisfaction score (1 'very good'; 6 'unsatisfactory') with it was 1.45 (0.55), and 92% recommended it. Half of the urologists reported time savings. CONCLUSION: Patients and urologists report a very high level of acceptance and satisfaction with this online tool. It offers advantages in shared decision-making and time efficiency. The usage of the decision aid might improve the adoption of active surveillance and watchful waiting when indicated.

VOC-based detection of prostate cancer using an electronic nose and ion mobility spectrometry: A novel urine-based approach.

BACKGROUND: Many diseases leave behind specific metabolites which can be detected from breath and urine as volatile organic compounds (VOC). Our group previously described VOC-based methods for the detection of bladder cancer and urinary tract infections. This study investigated whether prostate cancer can be diagnosed from VOCs in urine headspace. METHODS: For this pilot study, mid-stream urine samples were collected from 56 patients with histologically confirmed prostate cancer. A control group was formed with 53 healthy male volunteers matched for age who had recently undergone a negative screening by prostate-specific antigen (PSA) and digital rectal exam. Headspace measurements were performed with the electronic nose Cyranose 320TM. Statistical comparison was performed using principal component analysis, calculating Mahalanobis distance, and linear discriminant analysis. Further measurements were carried out with ion mobility spectrometry (IMS) to compare detection accuracy and to identify potential individual analytes. Bonferroni correction was applied for multiple testing. RESULTS: The electronic nose yielded a sensitivity of 77% and specificity of 62%. Mahalanobis distance was 0.964, which is indicative of limited group separation. IMS identified a total of 38 individual analytical peaks, two of which showed significant differences between groups (p < 0.05). To discriminate between tumor and controls, a decision tree with nine steps was generated. This model led to a sensitivity of 98% and specificity of 100%. CONCLUSIONS: VOC-based detection of prostate cancer seems feasible in principle. While the first results with an electronic nose show some limitations, the approach can compete with other urine-based marker systems. However, it seems less reliable than PSA testing. IMS is more accurate than the electronic nose with promising sensitivity and specificity, which warrants further research. The individual relevant metabolites identified by IMS should further be characterized using gas chromatography/mass spectrometry to facilitate potential targeted rapid testing.

Development and outcomes of surgical and urological kidney transplantation programs in Germany: a total population analysis from 2006 to 2021.

PURPOSE: Kidney transplantation (KT) is the most frequently performed organ transplantation. In Germany, KT is performed in urology and surgery departments with unknown consequences of this parallel structure. The aim of the study was to compare the development and outcome of KT in urology and surgery departments. METHODS: On an institutional level, we analyzed the annual caseload from 2006 to 2021 with the reimbursement. INFO tool based on hospitals' quality reports (Reimbursement Institute, Hürth, Germany). For outcome comparison we extracted raw data from the transplantation centers' quality reports (Deutsche Stiftung Organtransplantation, DSO). RESULTS: A total of 23,599 cases (17,781 deceased donor and 5,818 living donor KTs) were included. The total number of KTs decreased from 1851 in 2006 to 1701 in 2021 (- 8%; p = 0.12). The total number of urological KTs decreased from 592 cases in 2006 to 395 cases in 2021 (- 33.3%; p = 0.01). Further analysis revealed no significant differences between intra- and postoperative complications and graft quality at one year for deceased donor KTs (DDKT) although differences in immediate renal function and graft quality at discharge could be observed. There were no significant differences in immediate renal function and graft quality at discharge for living donor KTs (LDKT) between the specialties. CONCLUSION: KTs performed in urology departments declined between 2006 and 2021. Nevertheless, intra- and postoperative complications as well as long-term function did not differ between surgical and urological KT programs. Hence, an interdisciplinary approach, especially considering the upcoming challenges in KT as, e.g., robot-assisted surgery seems reasonable.

Old for young kidney transplantation: a responsible option for our patients to reduce waiting time?

PURPOSE: The Eurotransplant Senior program allocating grafts from donors ≥ 65 years to recipients aged ≥ 65 years has proven good results within the last 20 years. However, "old" grafts are also allocated to younger recipients < 65 years, and this outcome of "old for young" kidney transplantations (KT) still lacks detailed investigations. METHODS: All "old for young" KT performed at four tertiary referral centers were retrospectively compared including a recent follow-up, stratifying for "old for young" (donor ≥ 65 years to recipient < 65 years) vs. "very old for young" KT (donor ≥ 70 years to recipient < 65 years). RESULTS: Overall, 99 patients were included with 56 (56.6%) "old for young" and 43 (43.4%) "very old for young" KT. The median waiting time did not differ (60.7 vs. 45.8 months, respectively) at comparable living donation rates (57.1% vs. 44.2%) as well as intra- and postoperative results. At a median follow-up of 44 months (range 1; 133), the 3-year graft survival of 91% vs. 87% did not significantly vary. In subgroup analyses assessing living donation or donation after brain death (DBD) KT only, the graft survival was significantly longer for "old for young" KT within the living donation subgroup. In multivariate Cox regression analyses, the presence of panel-reactive antibodies was the only significant impact factor on graft survival (HR 8.32, p = 0.001). CONCLUSION: This analysis clearly demonstrates the effectiveness of the "old for young" approach, enabling favorable perioperative results as well as comparable data of graft- and overall survival, while reducing waiting time for eligible patients.

Enhancing Human Papillomavirus Vaccination Rates through Better Knowledge? Insights from a Survey among German Medical Students.

INTRODUCTION: Vaccination against human papillomavirus (HPV) significantly reduces the risk for malignant diseases like cervix, anal, or penile cancer. However, although vaccination rates are rising, they are still too low mirroring a lack of disease awareness in the community. This study aims to evaluate knowledge about HPV vaccination as well as the vaccination rate among German medical students. MATERIAL AND METHODS: Medical students were surveyed during a German medical students' sports event. The self-designed survey on HPV vaccination consisted of 24 items. The data collection was anonymous. RESULTS: Among 974 participating medical students 64.9% (632) were women, 335 (34.4%) were male and 7 (0.7%) were nonbinary. Mean age was 23.1 ± 2.7 (± standard deviation; range 18-35) years. Respondents had studied mean 6.6 ± 3.3 (1-16) semesters and 39.4% (383) had completed medical education in urology. 613 (64%) respondents reported that HPV had been discussed during their studies. 7.6% (74) had never heard of HPV. In a multivariate model female gender, the knowledge about HPV, and having worked on the topic were significantly associated with being HPV-vaccinated. Older students were vaccinated less likely. CONCLUSIONS: Better knowledge and having worked on the topic of HPV were associated with a higher vaccination rate. However, even in this highly selected group the knowledge about HPV vaccination was low. Consequently, more information and awareness campaigns on HPV vaccination are needed in Germany to increase vaccination rates.

[Comparison of hospital rating websites among each other and with data from hospital quality reports and quality assurance based on routine data]. / Vergleich von Patientenbewertungen auf Online-Portalen untereinander und mit Qualitätsberichten der Krankenhäuser und der Qualitätssicherung mit Routinedaten.

BACKGROUND: In addition to the objectifiable treatment quality, patients' perspectives are gaining relevance. OBJECTIVE: This study aimed to characterize available hospital rating websites (HRW) with regards to patient ratings and to compare them with data from hospital quality reports and quality assurance based on routine data (QSR) for urological departments. MATERIALS AND METHODS: After a structured online search for HRWs, websites were compared based on patient ratings from the 10 urologic departments with the largest intervention rates in 2021 using generalized estimated equations. For radical prostatectomy (RPE), quantitative comparison of patient ratings (klinikbewertungen.de) and QSR-based ratings was performed using Spearman's rank correlation. RESULTS: Of 1845 hits, 25 portals were analyzed. The department-wise comparison of HRWs resulted in significantly different patient ratings (p < 0.001). Patient ratings (klinikbewertungen.de) and QSR data (AOK-Gesundheitsnavigator) showed no significant correlation. An internal comparison of QSR data and patient ratings from the AOK-Gesundheitsnavigator on RPE showed a significant negative correlation between the overall rating and unplanned reoperations (r = -0.81) or other complications (r = -0.91). There was no significant correlation with the recommendation rate by patients. CONCLUSION: Hospital rating websites show considerable heterogeneity regarding patient ratings of the same urology department in different portals. Furthermore, based on the selected examples, there seems to be no correlation between subjective and objective evaluations between different websites or within one website.

End-of-Life Care Preferences of Patients with Advanced Urological Malignancies: An Explorative Survey Study at a Tertiary Referral Center.

Background: Many people want to die at home, but it is often not possible because they do not share their wishes with family members. This study was conducted to find out the extent to which patients with advanced urological malignancies had wishes regarding their final stage of life, made arrangements accordingly, and communicated their wishes to relatives and health care professionals. Methods: We conducted a survey among advanced urological tumor patients during their clinic visit at a German university hospital using a 31-item questionnaire. Inclusion criteria were metastatic or irresectable prostate cancer, urothelial carcinoma, or renal cell carcinoma. Results: In total, 88 patients (76 male, 12 female) completed the questionnaire, and 62 of those respondents (70%) had received their tumor diagnosis within the past 5 years. Symptoms were reported by 80%, and 18% described five or more symptoms. The majority (88%) stated that they had thought about their preferred place of death but 58% had not informed anyone about it. The preference for a hospice as the place of death correlated statistically significantly with the absence of a domestic partnership (p = 0.001) or marriage (p < 0.001) and with a high number of symptoms (≥5; p = 0.009). However, 73% had not talked with their urological oncologist about care options in case their health deteriorated though 36% of those were interested in having a conversation about it. Conclusions: Our results showed that 9 out of 10 patients reflected on their preferred place of death but only a few discussed it with anyone. Based on this finding, physicians and healthcare staff should initiate discussions about early care planning so that patients in incurable situations can express their wishes regarding their preferred place of death.

Trends in kidney transplantation and living donor nephrectomy in Germany: a total population analysis from 2006 to 2021.

PURPOSE: To analyze recent trends of surgical access routes, length of hospital stay (LOS), and mortality in kidney transplantation (KT) and living donor nephrectomy (LDN) in Germany. MATERIALS AND METHODS: We studied the nationwide German hospital billing database and the German hospital quality reports from 2006 to 2021. RESULTS: There were a total of 35.898 KTs. In total, 9044 (25%) were living donor transplantations, while 26.854 (75%) were transplantations after donation after brain death (DBD). The share of open LDN decreased from 82% in 2006 to 22% in 2020 (- 4%/year; p < 0.001). The share of laparoscopic LDN increased from 18% in 2006 to 70% in 2020 (+ 3%/year; p < 0.001). The share of robotic LDN increased from 0% in 2006 to 8% in 2020 (+ 0.6%/year; p < 0.001). Robotic-assisted KT increased from 5 cases in 2016 to 13 procedures in 2019 (p = 0.2). LOS was shorter after living donor KT, i.e., 18 ± 12.1 days versus 21 ± 19.6 days for DBD renal transplantation (p < 0.001). Moreover, LOS differed for open versus laparoscopic versus robotic LDN (9 ± 3.1 vs. 8 ± 2.9 vs. 6 ± 2.6; p = 0.031). The overall in-hospital mortality was 0.16% (n = 5) after LDN, 0.47% (n = 42) after living donor KT and 1.8% (n = 475) after DBD KT. CONCLUSIONS: There is an increasing trend toward minimal-invasive LDN in recent years. Overall, in-hospital mortality was low after KT. However, 5 deceased healthy donors after LKD caution that the risks of this procedure should also be taken very seriously.

Trends in the use of testicular prostheses in Germany: a total population analysis from 2006-2021.

INTRODUCTION: Testicular tumors are the most common malignancies in young adults and their incidence is growing. The implantation of a testicular prosthesis, for example, during orchiectomy is a standard procedure but its frequency in Germany is unknown. This study aims to analyze trends of testicular prosthesis implantation in recent years in Germany. MATERIAL AND METHODS: The nationwide German hospital billing database and the German hospital quality reports from 2006 to 2021 were studied. RESULTS: A total of 12,753 surgical procedures with implantation of testicular prosthesis and 1,244 procedures with testicular prosthesis explantation were included. Testicular prosthesis implantation increased in total from 699 cases in 2006 to 870 cases in 2020 (+11.4 cases/year; p < 0.001). The share of implantation of testicular prosthesis due to testicular tumor decreased from 72.6% in 2006 to 67.5% in 2020 (p < 0.001). The share of implantation due to gender affirming surgery increased from 6.8% in 2006 to 23.3% in 2020 (p < 0.001). The share of implantation due to testicular atrophy decreased from 11.4% in 2006 to 3.4% in 2020 (p < 0.001). Simultaneous implantation of testicular prosthesis during orchiectomy for testicular cancer increased from 7.8% in 2006 to 11.4% in 2020 (p < 0.001). In 2006, 146 hospitals (85%) performed < 5 testicular prosthesis implantation, while 20 hospitals (12%) performed 5-15 implantation procedures and 6 hospitals (3%) performed > 15 testicular implantation surgeries. In 2021, 115 hospitals (72%) performed < 5 testicular prosthesis implantation, while 39 hospitals (25%) performed 5-15 implantation procedures and 5 hospitals (3%) performed > 15 testicular implantation surgeries. CONCLUSION: This study shows that implantation of testicular prostheses is steadily increasing. Explantation rates are low. Besides testicular cancer transgender surgeries were the main driver for increasing case numbers in recent years.

[Geriatric assessment - What should be done and considered before starting therapy of mHSPC and mCRPC?] / Geriatrisches Assessment ­ Was sollte vor Therapiebeginn des mHSPC und des mCRPC gemacht und bedacht werden?

The systemic treatment of prostate cancer nowadays is predominantly carried out with combination therapies. A range of aspects should be respected in older and comorbid patients, in order to avoid toxicities and to achieve a successful therapy alongside good quality of life. The definition of geriatric patients is not primarily based on chronological age but rather on the overall health condition and life expectancy. Comorbid patients > 70 years should undergo a three-step geriatric screening before treatment initiation. If the G8 screening and/or mini-COG shows abnormalities (taking into account nutrition, comorbidity/medication, mobility, and cognition), a simplified geriatric assessment is recommended. Patients can then be stratified into three groups (fit, vulnerable, frail). Only a few cases warrant a complete geriatric assessment. Treatable deficits in the above mentioned domains should be improved if possible. When choosing a systemic therapy, fit patients can be treated the same as non-geriatric patients. Vulnerable and frail patients are under a higher risk for toxicities, so special care should be taken. While the diverse substances of hormonal therapy are usually well tolerated (even though some substance-specific toxicities can occur), haematotoxic substances such as taxanes or olaparib can only be recommended in select cases. As falls - especially under hormonal therapy - are a common problem, osteoprotective therapy should especially be considered. Upon progression of the tumour disease, there should not be a reflex to simply switch to the next line of treatment, but an individual concept should be established together with the patient and his relatives, taking into account aspects of palliative care and patient needs and focussing on quality of life and also setting therapy limitations.

[Patient events in German urology: trend towards hybrid formats?] / Patientenveranstaltungen in der deutschen Urologie: Trend zu Hybridformaten?

BACKGROUND: Patient events are an important tool to respond to the increasing need of the public for health information. Through the "patient forum", the German Society of Urology (DGU) is committed to patient information and public relations at its annual congresses. The goal of the study was to evaluate the events from 2017-2019 and to compare them with the first digital patient forum in 2020. MATERIALS AND METHODS: Using a two-page standardized questionnaire, we surveyed the visitors of the presence patient forums (presence group = P) of the three annual congresses of the DGU 2017-2019 as well as the users of the digital event 2020 (online group = O). RESULTS: We obtained 71 records for 2017-2019 and 18 for 2020. The median age of visitors was 64 years (range 30-89). Males were 66% (P) vs. 83% (O) of participants (p = 0.005). The offer was rated overall as good to very good by both groups, i.e., 1.6 (P) vs. 1.6 (O; p = 0.7) on a scale from 1 to 6 with 1 being the highest rating. In line with the lower interaction in the digital format, the possibility to ask questions was rated worse with 1.5 (P) vs. 2.8 (O; p = 0.003). When asked about the desired future event format, two-thirds of the users of the digital patient forum were in favor of a hybrid event on-site and online. CONCLUSION: Patient events are suitable means of communication for the public and are rated well by visitors. In particular, interaction with experts is highly valued. Face-to-face formats are associated with a high logistical effort and high costs, and their reach is limited. In the future, hybrid formats could be a reasonable alternative, as they combine the advantages of online and face-to-face formats.
