Background and Objective: Patients struggle to classify symptoms, which hinders timely medical presentation. With 35-75% of patients seeking information online before consulting a health care professional, generative language-based artificial intelligence (AI), exemplified by ChatGPT-3.5 (GPT-3.5) from OpenAI, has emerged as an important source. The aim of our study was to evaluate the role of GPT-3.5 in triaging acute urological conditions to address a gap in current research., Methods: We assessed GPT-3.5 performance in providing urological differential diagnoses (DD) and recommending a course of action (CoA). Six acute urological pathologies were identified for evaluation. Lay descriptions, sourced from patient forums, formed the basis for 472 queries that were independently entered by nine urologists. We evaluated the output in terms of compliance with the European Association of Urology (EAU) guidelines, the quality of the patient information using the validated DISCERN questionnaire, and a linguistic analysis., Key Findings and Limitations: The median GPT-3.5 ratings were 4/5 for DD and CoA, and 3/5 for overall information quality. English outputs received higher median ratings than German outputs for DD (4.27 vs 3.95; p  < 0.001) and CoA (4.25 vs 4.05; p  < 0.005). There was no difference in performance between urgent and non-urgent cases. Analysis of the information quality revealed notable underperformance for source indication, risk assessment, and influence on quality of life., Conclusion and Clinical Implications: Our results highlights the potential of GPT-3.5 as a triage system for offering individualized, empathetic advice mostly aligned with the EAU guidelines, outscoring other online information. Relevant shortcomings in terms of information quality, especially for risk assessment, need to be addressed to enhance the reliability. Broader transparency and quality improvements are needed before integration into, primarily English-speaking, patient care., Patient Summary: We looked at the performance of ChatGPT-3.5 for patients seeking urology advice. We entered more than 400 German and English inputs and assessed the possible diagnoses suggested by this artificial intelligence tool. ChatGPT-3.5 scored well in providing a complete list of possible diagnoses and recommending a course of action mostly in line with current guidelines. The quality of the information was good overall, but missing and unclear sources for the information can be a problem., (© 2024 The Author(s).)

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., (© 2024. The Author(s).)

Aim and Objectives: We aimed to test the predictive value of readily accessible and easily performed post-surgical "bedside tests" on their validity of long-term urinary incontinence (UI) (≥12 months) in patients following robot-assisted laparoscopic radical prostatectomy (RALP). Material and Methods: Patients undergoing RALP between July 2020 and March 2021 were prospectively included and subdivided into two groups based on their pad usage after 12 months (0 vs. ≥1 pad). After catheter removal, patients performed a 1 h pad test, documented the need for pad change in a micturition protocol and received post-voiding residual urine volume ultrasound. Univariate and multivariable analyses were used to demonstrate the predictive value of easily accessible tests applied after catheter removal for UI following RALP. Results: Of 109 patients, 47 (43%) had to use at least one pad (vs. 62 (57%) zero pads) after 12 months. Univariate testing showed a significant difference in urine loss between both groups evaluated by the 1 h pad test performed within 24 h after catheter removal (70% < 10 mL, vs. 30% ≥ 10 mL, p = 0.004) and in the need for pad change within the first 24 h after catheter removal (14% dry pads vs. 86% wet pads, p = 0.003). In multivariable analyses, the combination of both tests (synoptical incontinence score) could be confirmed as an independent predictor for UI after 12 months ( p = 0.011). Conclusions: Readily accessible "everyday" diagnostics (pad test/change of pads after catheter removal) following RALP seem to be associated with a higher rate of long-term UI. This finding is crucial since patients with a potentially higher need for patient education and counselling can be identified using these readily accessible tests. This could lead to a higher patient satisfaction and improved outcomes.

Purpose: Long-term results on quality of life (QoL) as well as clinical outcomes of intermittent self-dilatation (ISD) of the urethra after direct visual internal urethrotomy (DVIU) are scarce. The aim of this study was to prospectively evaluate patient reported outcomes (PROs) on voiding symptoms and QoL in a large cohort of urethral stricture patients performing ISD., Methods: We identified a total of 121 patients who performed ISD following DVIU between 2008 and 2013. Baseline assessment was conducted for each patient before ISD was started. Follow-up visits were scheduled in 6-month intervals. Each assessment included the following questionnaires: International prostate symptom score (IPSS), IPSS quality of life index (IPSS-QoL), patient global impression of severity (PGI-S), and patient global impression of improvement (PGI-I). Additional parameters were maximum urinary flow rate (Q max ), postvoid residual urine, rate of complications, and stricture recurrence. Linear mixed models were used to examine the change over the course of the follow-up visits to the baseline., Results: The median age of the patients was 58 years (interquartile range [IQR]: 43-70). The median follow-up was 17 months (IQR: 7-30). Mean change from baseline IPSS was -6.1, -5.9, -4.2, and -4.8 points at 6, 24, 36, and 48 months. Mean change from baseline IPSS-QoL was -1.3, -1.4, -1.6, and -1.8 points, respectively. Mean PGI-I was 1.7 points at 6, 1.9 points at 24, 1.9 points at 36, and 2.2 points at 48 months after ISD initiation. Mean change of Q max ranged from 1.7 at 6 to 2.2 mL/s at 48 months. The median complication rate was 3.3% per 6-month ISD interval. Overall, 11 patients developed stricture recurrence (9%)., Conclusion: ISD after DVIU had no negative impact on patients' QoL (IPSS-QoL, PGI-I, PGI-S). Urodynamic parameters remained stable for up to 48 months with low complications and an acceptable stricture recurrence rate., (© 2024 Wiley Periodicals LLC.)

Introduction: We evaluated the effectiveness and safety profile of the tyrosine kinase inhibitor sunitinib in patients with advanced or metastatic renal cell carcinoma (a/mRCC) in a real-world setting., Methods: We analyzed data of adult a/mRCC patients treated with sunitinib. Data were derived from the German non-interventional post-approval multicenter STAR-TOR registry (NCT00700258). Progression-free survival (PFS), overall survival (OS), and adverse events (AEs) were evaluated using descriptive statistics and survival analyses for the entire cohort and patient subgroups., Results: A total of 116 study sites recruited 702 patients treated with sunitinib (73.1% male; median age 68.0 years; median Karnofsky index 90%) between November 2010 and May 2020. The most frequent histological subtype was clear cell RCC (81.6%). Sunitinib was administered as first-line treatment in 83.5%, as second line in 11.7%, and as third line or beyond in 4.8% of the patients. Drug-related AEs and serious AEs were reported in 66.3% and 13.9% of the patients, respectively (most common AE: gastrointestinal disorders; 39.7% of all patients)., Conclusions: This study adds further real-world evidence of the persisting relevance of sunitinib for patients with a/mRCC who cannot receive or tolerate immune checkpoint inhibitors. The study population includes a high proportion of patients with unfavorable MSKCC poor-risk score, but shows still good PFS and OS results, while the drug demonstrates a favorable safety profile. The STAR-TOR registry is also registered in the database of US library of medicine (NCT00700258)., (© 2024 S. Karger AG, Basel.)

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., (© 2024 The Author(s). Published by S. Karger AG, Basel.)

Purpose: To test the association between the Charlson-Deyo Comorbidity Index (CCI) and the recurrence of non-muscle-invasive bladder cancer (NMIBC)., Methods: NMIBC (Ta, T1, TIS) patients who underwent transurethral resection of bladder tumor (TURB) between 2010 and 2018 were identified within a retrospective data repository of a large university hospital. Kaplan-Meier estimates and uni- and multivariable Cox regression models tested for differences in risk of recurrence according to low vs. high comorbidity burden (CCI ≤ 4 vs. >4) and continuously coded CCI., Results: A total of 1072 NMIBC patients were identified. The median follow-up time of the study population was 55 months (IQR 29.6-79.0). Of all 1072 NMIBC patients, 423 (39%) harbored a low comorbidity burden vs. 649 (61%) with a high comorbidity burden. Overall, the rate of recurrence was 10% at the 12-month follow-up vs. 22% at the 72-month follow-up. In low vs. high comorbidity burden groups, rates of recurrence were 6 vs. 12% at 12 months and 18 vs. 25% at 72 months of follow-up ( p = 0.02). After multivariable adjustment, a high comorbidity burden (CCI > 4) independently predicted a higher risk of recurrence (HR 1.42, 95% confidence interval (CI) 1.06-1.92, p = 0.018). After multivariable adjustment, the hazard of recurrence increased by 5% per each one-unit increase on the CCI scale (HR 1.05, 95% CI 1.00-1.10, p = 0.04)., Conclusions: Comorbidities in NMIBC patients are common. Our data suggest that patients with higher CCI have an increased risk of BC recurrence. As a consequence, patients with a high comorbidity burden should be particularly encouraged to adhere to NMIBC guidelines and conform to follow-up protocols.

Background: YouTube is the second most popular website worldwide. It features numerous videos about radical prostatectomy. The aim of this study was to assess the quality of these videos and screen their benefit for patients and doctors., Methods: All videos on YouTube about radical prostatectomy were analysed using a specially developed software (python 2.7, numpy). According to a predefined selection process most relevant videos were analyzed for quality and reliability using Suitability Assessment of Materials (SAM)-Score, Global Quality Score and others., Results: Out of 3520 search results, 179 videos were selected and analysed. Videos were watched a median of 5836 times (interquartile range (IQR): 11945.5; 18-721546). The median duration was 7.2 minutes (min). 125 of the videos were about robotic prostatectomy. 69 videos each were directly addressed to patients and doctors. Medical content generally was of low quality, while technical quality and total quality were at a high level. Reliability was good., Conclusions: Videos on radical prostatectomy on YouTube allow for patient information. While technical quality and reliability are classified as acceptable, medical content was low and warranted preselection. In contrast to Loeb et al. we did not observe a negative correlation between number of views and scientific quality in different scores. Our findings support the need for preselection of videos on YouTube as the potential benefit may vary between videos with the significant risk of low medical quality., Competing Interests: The authors declare no conflict of interest., (© 2023 The Author(s).)

Introduction: Multiparametric magnetic resonance imaging guided prostate biopsy (mpMRI PBx) leads to a higher rate of successful nerve-sparing in robot-assisted laparoscopic prostatectomy (ns-RALP) for prostate cancer (PCa). This study aimed to evaluate the impact of mpMRI PBx compared to standard ultrasound-guided PBx on functional outcomes focusing on erectile function in patients following ns-RALP., Material and Methods: All RALPs performed between 01/2016 and 06/2021 were retrospectively stratified according to (attempted) ns vs. non ns RALPs and were then categorized based on the PBx technique (mpMRI PBx vs. standard PBx). We compared RALP outcomes such as pathological tumor stage, rates of secondary nerve resection (SNR) and positive surgical margin status (PSM). Furthermore, we explored the association between PBx-technique and patient-reported outcomes assessed 12 months after RALP using the prospectively collected 26-item Expanded Prostate Cancer Index Composite (EPIC-26) questionnaire. Chi-square tests and logistic regression analysis were conducted., Results: A total of 849 RALPs included 517 (61%) procedures with (attempted) ns. Among these, 37.5% were diagnosed via preoperative mpMRI PBx. Patients with a preoperative standard PBx had a 57% higher association of PSM ( p  = 0.030) compared to patients with mpMRI PBx and a 24% higher risk of erectile dysfunction (ED) 12 months post RALP ( p  = 0.025). When ns was attempted, we observed a significantly higher rate of SNR in patients who underwent a standard PBx compared to those who received a mpMRI PBx (50.8% vs. 26.7%, p  < 0.001) prior RALP. In comparison, upgrading occurred more often in the standard PBx group (50% vs. 40% mpMRI PBx, p  = 0.008)., Conclusion: The combination of mpMRI PBx for PCa diagnosis followed by ns-RALP resulted in significantly fewer cases of SNR, better oncological outcomes and reduced incidence of ED 1 year after surgery. This included fewer PSM and a lower rate of postoperative tumor upgrading., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Leitsmann, Uhlig, Bremmer, Mohr, Trojan, Leitsmann and Reichert.)

Introduction: We tested for regional-specific differences in patient, tumor and treatment characteristics as well as cancer-specific mortality (CSM) of squamous cell carcinoma of the penis (SCCP) patients, across the Surveillance, Epidemiology, and End Results (SEER) registries., Methods: The SEER database (2000-2018) was used to tabulate patient (age at diagnosis, race/ethnicity), tumor (stage, grade, N-stage) and treatment characteristics (proportions of primary tumor surgery, local lymph node surgery, systemic therapy), according to 12 SEER registries. Multinomial regression models, as well as multivariable Cox regression models tested for CSM differences, adjusting for patient, tumor and treatment characteristics., Results: In 5395 SCCP patients, registry-specific patient counts ranged from 2060 (38 %) to 64 (1 %). Differences across registries existed for race/ethnicity, stage, grade and N-stage. Additionally, in stage I-II SCCP patients, proportions of local tumor destruction (LTD) ranged from 19 % to 39 % and from 33 % to 61 % for partial penectomy. In stage III-IV SCCP patients, proportions of partial penectomy ranged from 40 % to 59 % and from 17 % to 50 % for radical penectomy. Local lymph node surgery ranged from 8 % to 24 % and proportions of systemic therapy ranged from 3 % to 14 %. Significant inter-registry differences remained, after adjustment for treatment proportions. Unadjusted five-year CSM ranged from 19 % to 32 %. In multivariable analyses, one registry exhibited significantly higher CSM (SEER registry 10, Hazard Ratio [HR] 1.48), relative to the largest reference registry (SEER registry 1, n = 2060)., Conclusion: Important regional differences including patient, tumor and treatment characteristics exist for SCCP patients across SEER registries. After multivariable adjustment, no differences in CSM were recorded, with the exception of one registry., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Purpose: Hospital rating websites (HRW) offer decision support in hospital choice for patients. To investigate the impact of HRWs of uro-oncological patients undergoing elective surgery in Germany., Methods: From 01/2020 to 04/2021, patients admitted for radical prostatectomy, radical cystectomy, or renal tumor surgery received a questionnaire on decision-making in hospital choice and the use of HRWs at 10 German urologic clinics., Results: Our study includes n = 812 completed questionnaires (response rate 81.2%). The mean age was 65.2 ± 10.2 years; 16.5% were women. Patients were scheduled for prostatectomy in 49.1%, renal tumor surgery in 20.3%, and cystectomy in 13.5% (other 17.1%). Following sources of information influenced the decision process of hospital choice: urologists' recommendation (52.6%), previous experience in the hospital (20.3%), recommendations from social environment (17.6%), the hospital's website (10.8%) and 8.2% used other sources. Only 4.3% (n = 35) used a HRW for decision making. However, 29% changed their hospital choice due to the information provided HRW. The most frequently used platforms were Weisse-Liste.de (32%), the AOK-Krankenhausnavigator (13%) and Qualitaetskliniken.de (8%). On average, patients rated positively concerning satisfaction with the respective HRW on the Acceptability E-Scale (mean values of the individual items: 1.8-2.1)., Conclusion: In Germany, HRWs play a minor role for uro-oncologic patients undergoing elective surgery. Instead, personal consultation of the treating urologist seems to be far more important. Although patients predominantly rated the provided information of the HRW as positive, only a quarter of users changed the initial choice of hospital., (© 2023. The Author(s).)

Background: Elective scrotal surgery is associated with a high rate of postoperative complications. There is no specific recommendation for postoperative care., Aim: We investigated whether support underwear has an impact on postoperative complications and quality of life., Materials and Methods: From July 2020 to November 2021, patients with prior elective scrotal surgery were randomized into the intervention group "support underwear" or the control group. In addition to patient characteristics, intraoperative and postoperative findings were documented. The primary endpoint comprised postoperative complications. Secondary endpoints were prolonged length of hospital stay, emergency visits, unplanned readmissions, increased use of analgesics, and quality of life, which was recorded using the EQ5D (European Quality of Life 5 Dimensions) questionnaire preoperatively, on day 1 and 4 weeks postoperatively., Results: Data from 50 patients were analyzed. The mean age was 46.7 years (standard deviation [SD] 18.6). Inguinal surgery with/without orchiectomy (52%), hydrocele resection (22%), or ligation of varicocele (14%) were performed most frequently. The mean operating time was 62.8 min (SD 35.2); length hospital stay was 2.6 days (SD 1.2). In all, 20% of the patients suffered a postoperative complication. Type of surgery was significantly associated with postoperative complications (p = 0.01) and unplanned readmission (p = 0.04). Regarding biometric and perioperative data, there were no significant differences between the interventional group (n = 27) and control group (n = 23)., Conclusion: A nonnegligible number of complications occurs after elective scrotal surgery. Complications affects quality of life up to 4 weeks after the surgery. Postoperative care with support underwear does not appear to affect the postoperative complication rate, but it positively influences the quality of life in patients with scrotal access., (© 2022.

Background: Digitalization of patient documentation and introduction of the electronic patient record (ePA) pose challenges to everyday clinical practice., Objectives: We investigated the acceptance and status of the digitalization of patient data and the introduction of the ePA among German urologists., Materials and Methods: A questionnaire with 30 questions about the acceptance and status of digitalization of patient documentation and ePA was sent out via the newsletter of the German Society of Urology., Results: A total of 80 urologists participated in the survey (response rate 2%). Digital platforms such as Urotube or Researchgate are used by 63% of participants. The complete implementation of digital patient documentation was reported by 72% of respondents working in medical practice and by 54% of those working in the hospital (p = 0.042). While 76% see the digitalization process as reasonable, 34% expressed partial or strong concerns about the complete digitalization of patient documentation. Only 14% of the participants offer video consultations. Advantages for ePA include better networking of the healthcare system (73%), improved diagnosis, indication (41%) and treatment quality (48%), and avoidance of medication errors (70%)., Conclusion: German urologists are open to the digitalization process and ePA. Especially younger urologists are using digital media. The advantages of digitalization are, in particular, an improvement in treatment processes. For a smooth introduction, a cross-departmental establishment and, if necessary, an adaptation of the treatment processes are necessary., (© 2022. The Author(s).)

Background: Several international medical societies reported a negative impact on urology residency training programs due to the COVID-19 pandemic., Objectives: The aim of this study was to investigate the impact of the pandemic on urological residency in Germany., Materials and Methods: From the 20 th of May 2020 until the 20 th of June 2020, a Germany-wide online survey on the continuing residency training was distributed via the members of the working group, social media (Facebook, Twitter, Instagram) and the German Society of Residents in Urology (GeSRU e.V.) newsletter. The survey covered 3 topics: 1) basic characteristics of the participants, 2) general and 3) subjective influence of the COVID-19 pandemic on clinics and further residency training., Results: A total of 50 residents took part in the survey; 54% were women. The median age was 31 years. Most of the participants were in their 2nd (22%) and 5th (26%) year of training and worked in a university hospital (44%) or in a clinic of maximum care (30%). 38% of the respondents stated that they only served urological emergencies during the COVID-19 pandemic. For 28% this meant a very large delay (80-100%) in the specialisation, while 28% stated only a minor impact. 66% documented training impairments caused by fewer operations, low patient numbers in the outpatient department (50%), congress (50%) and workshop (44%) cancellations. 46% of residents reported direct contact with COVID-19 patients while 10% were deployed on interdisciplinary IMC units. Numerous physical distancing and hygiene measures have been implemented by the clinics., Conclusion: On average, around 50% of the urology residents indicated significant restrictions in training due to the COVID-19 pandemic in Germany. The delay in training cannot currently be measured in units of time, but it can be assumed that training for residents during the pandemic is likely to be of a lower quality compared to previous generations., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Background: The surgical management of benign prostatic obstruction (BPO) has greatly evolved in recent years., Objectives: The aim of this study is to present contemporary management and trends for surgical BPO therapy in Germany., Materials and Methods: Disease and procedure rates were extracted using the online platform reimbursement.INFO that is based on German hospital quality report data. For the diagnosis of benign prostate hyperplasia (BPH), the ICD codes N40 and D29.1 were used. For evaluation of the surgical procedures OPS codes 5‑600.0, 5‑601, 5‑603, 5‑609.4 and 5‑609.8 including their subcodes were used. In addition to descriptive analyses, trend and correlation analyses were performed., Results: In 2019, a total of 83,687 procedures for BPO in 473 urological departments were performed. The most common (71.7%) surgery was transurethral resection of the prostate (TUR-P). Holmium laser enucleation of the prostate (HoLEP; 9.5%) and surgical adenomectomy (5.6%) were the second and third most common procedures. Less often thulium laser enucleation (ThuLEP; 3.1%), laser vaporisation (2.9%) and electrical vaporisation (2.8%) were performed. All other techniques were performed in < 1%. Rates of HoLEP, ThuLEP and electrovaporisation have increased since 2006 (HoLEP: +42.42%/year, p < 0.001; ThuLEP: +20.6%/year, p = 0.99; electrovaporisation +43.42%/year, p < 0.001), while surgical adenomectomy decreased (-1.66%/year, p < 0.01). In 2019 mean length of hospital stay was 5.1 ± 0.1 days., Conclusions: TUR‑P remains the most often performed surgical treatment for BPO. Laser therapy-especially in centers-is increasing, while surgical adenomectomy continues to abate., (© 2022. The Author(s).)

Background: The aim of our study was to evaluate the impact of prostate biopsy technique (transrectal ultrasound (US)-prostate biopsy (PBx) versus multiparametric magnetic resonance imaging (mpMRI) targeted prostate biopsy (MRI-PBx) on intraoperative nerve-sparing and the rate of secondary neurovascular-bundle resection (SNR) in patients undergoing robot-assisted laparoscopic radical prostatectomy (RARP). A real-time investigation with a frozen-section examination (NeuroSAFE) microscopically excluded or confirmed prostate cancer invasion of the nerve structures resulting in preservation of the neurovascular bundle or SNR. Additionally, we analyzed risk factors related to SNR, such as longer operation time and postoperative complications., Methods: The total study cohort was stratified according to non-nerve-sparing versus nerve-sparing RARP. Patients with nerve-sparing approach were then stratified according to biopsy technique (PBx vs. MRI-PBx). Further, we compared PBx versus MRI-PBx according to SNR rate., Results: We included a total of 470 consecutive patients, who underwent RARP for PCa at our institution between January 2016 and December 2019. Patients with a preoperative MRI-PBx had a 2.12-fold higher chance of successful nerve-sparing (without SNR) compared to patients with PBx (p < 0.01). Patients with preoperative MRI-PBx required 73% less intraoperative SNR compared to patients with PBx (p < 0.0001). Prior MRI-PBx is thus a predictor for successful nerve-sparing RARP approach., Conclusion: Preoperative MRI-PBx led to better oncological outcomes and less SNR. Young patients with good erectile function could benefit from a preoperative MRI-PBx before nerve-sparing RARP., (© 2021 The Authors. The Prostate published by Wiley Periodicals LLC.)

Background: To test for the impact of patient comorbidities and medical risk factors on kidney function after partial (PN) or radical nephrectomy (RN) in renal cell carcinoma (RCC) patients with normal preoperative renal function., Materials and Methods: From January 2011 to December 2014, 195 consecutive RCC patients with a preoperative estimated glomerular filtration rate (eGFR) > 60 ml/min/1.73 m 2 underwent PN or RN. Stratification was performed according to postoperative acute kidney injury (AKI) vs. no AKI. Moreover, logistic regression models tested for risk factors predicting postoperative AKI and subsequent new-onset chronic kidney disease (eGFR < 60 or < 45 ml/min/1.73 m 2 )., Results: Of all eligible patients, 127 (65.1%) exhibited AKI. AKI patients underwent more frequently RN (44.9 vs. 13.2% PN) and harbored more often preoperative diabetes (17.3 vs. 5.9% no diabetes), hypertension (46.5 vs. 23.5% no hypertension) and larger median tumor size (4.5 vs. 2.5 cm, all p  < 0.05) than non-AKI patients. Moreover, after median follow-up of 14 months, 18.9% of AKI patients exhibited an eGFR < 60 ml/min/1.73 m 2 vs. 7.4% non-AKI patients ( p  = 0.01). In multivariable models, hypertension and RN were risk factors for postoperative AKI (both p  < 0.01). Age > 60 years and RN as well as preoperative diabetes were risk factors for postoperative eGFR < 60 or < 45 ml/min/1.73 m 2 (all p  < 0.05), respectively., Conclusions: Postoperative AKI is a non-negligible event especially after RN that can be further triggered by comorbidities such as diabetes and hypertension. Comorbidities should be considered in clinical decision-making for RCC surgery and patients need to be counseled about the increased risk of consecutive renal function impairment.

Purpose: To test the value of preoperative and postoperative cystatin C (CysC) as a predictor on kidney function after partial (PN) or radical nephrectomy (RN) in renal cell carcinoma (RCC) patients with normal preoperative renal function., Methods: From 01/2011 to 12/2014, 195 consecutive RCC patients with a preoperative estimated glomerular filtration rate (eGFR) > 60 ml/min/1.73m 2 underwent surgical RCC treatment with either PN or RN. Logistic and linear regression models tested for the effect of CysC as a predictor of new-onset chronic kidney disease in follow-up (eGFR < 60 ml/min/1.73m 2 ). Moreover, postoperative CysC and creatinine values were compared for kidney function estimation., Results: Of 195 patients, 129 (66.2%) underwent PN. In postoperative and in follow-up setting (median 14 months, IQR 10-20), rates of eGFR < 60 ml/min/1.73m 2 were 55.9 and 30.2%. In multivariable logistic regression models, preoperative CysC [odds ratio (OR): 18.3] and RN (OR: 13.5) were independent predictors for a reduced eGFR < 60 ml/min/1.73m 2 in follow-up (both p < 0.01), while creatinine was not. In multivariable linear regression models, a difference of the preoperative CysC level of 0.1 mg/dl estimated an eGFR decline in follow-up of about 5.8 ml/min/1.73m 2 . Finally, we observed a plateau of postoperative creatinine values in the range of 1.2-1.3 mg/dl, when graphically depicted vs. postoperative CysC values ('creatinine blind area')., Conclusion: Preoperative CysC predicts renal function impairment following RCC surgery. Furthermore, CysC might be superior to creatinine for renal function monitoring in the early postoperative setting., (© 2021. The Author(s).)

Background: Treating urinary incontinence and erectile dysfunction improves quality of life for many patients. In particular, sphincter and penile prostheses achieve very good results when conservative therapy options are exhausted. The aim of this study is to present the development and current state of sphincter and penile prosthesis implantation in Germany., Materials and Methods: We carried out an analysis of the Diagnosis Related Groups billing data in Germany from 2006-2016. We described the state of care in 2016 based on the German hospitals' quality reports., Results: Between 2006 and 2012 implantations of sphincter prostheses in Germany increased from 739 to 1112 (p < 0.001), the amount of implanting hospitals also increased from 129 to 206 (p < 0.001). From 2012-2016, the number of cases decreased to 980 and the number of hospitals to 198. In 2016, 168 (88%) urological hospitals implanted 1-9 sphincter prostheses and 23 (12%) hospitals implanted ≥ 10 sphincter prostheses. The top 10 hospitals (≥20 sphincters) implanted 34% (283/839) of all sphincters. Between 2006 and 2013 the number of implanted penile prostheses continuously increased from 263 to 503 (p < 0.001), the number of implanting hospitals from 71 to 107 (p < 0.001). From 2013-2016, the number of cases (p = 0.9) and the number of implanting hospitals (p = 0.5) stagnated. The proportion of penile prostheses implanted as part of gender reassignment surgery increased from 17% in 2006 to 25% in 2016 (p = 0.03). In 2016, 83 (85%) urological hospitals implanted 1-6 penile prostheses and 14 (15%) hospitals implanted ≥ 7 prostheses. The 7 top hospitals (≥20 prostheses/year) implanted 232/448 (52%) of the prostheses., Conclusions: The current state of urological endoprosthetics in Germany shows a small number of high-volume centers, but also a large number of hospitals with a small number of cases. Since 2012/2013, there has been a stagnation in the number of cases of penile and sphincter prosthesis implantations. In view of the number of radical prostatectomy cases, this development suggests an undersupply.

The aim of this study was to evaluate the association between axitinib, sunitinib and temsirolimus toxicities and patient survival in metastatic renal cell cancer patients. Overall survival (OS) and progression-free survival (PFS) of metastatic renal cell cancer patients from the prospective multicenter STAR-TOR study were assessed using multivariable Cox models. A total of 1195 patients were included (n = 149 axitinib; n = 546 sunitinib; n = 500 temsirolimus). The following toxicities significantly predicted outcomes: hand-foot skin reaction (hazard ratio [HR] = 0.29) for PFS with axitinib; stomatitis (HR = 0.62) and pneumonitis (HR = 0.23) for PFS with temsirolimus; stomatitis (HR = 0.52) and thrombocytopenia (HR = 0.6) for OS with temsirolimus; fatigue (HR = 0.71) for PFS with sunitinib; hand-foot skin reaction (HR = 0.56) and fatigue (HR = 0.58) for OS with sunitinib. In conclusion, in metastatic renal cell cancer, axitinib, sunitinib and temsirolimus demonstrate specific toxicities that are protective OS/PFS predictors.

From a survey, showing the available techniques at all the actual stand of abortion techniques in the different phases of pregnancy up to the second trimester are reported. Up to the 6th week of pregnancy vacuum curettage with a small canula, intravaginal and systemic application of prostaglandin-analoga as well as antigestagens are available. If there is an unproblematic situation in the first trimester up to the 12th week of pregnancy dilatation and curettage is the routine. In case of an individual risk there is a choice between save methods of dilatation with various applicable prostaglandins and - analoga as well as synthetic hydrophilic dilatators. Operation will be finished by section curettage or the classic curettage. In favour of the combined local systemic use of prostaglandins and analoga, installation methods are leaved. Oxytocin and application of synthetic hydrophilic dilatators are still important. Additional indications are necessary for operations at the uterus. Prophylaxis and metaphylaxis to avoid damages following treatment are reviewed.
