RESUMEN
BACKGROUND AND OBJECTIVE: Prostatic artery embolisation (PAE) and transurethral resection of the prostate (TURP) are two of the surgical options for treatment of lower urinary tract symptoms/benign prostatic obstruction (LUTS/BPO). Our aim was to compare the efficacy and safety of PAE and TURP for LUTS/BPO treatment at long-term follow-up. METHODS: We conducted a randomised, open-label, single-centre trial at a Swiss tertiary care centre. The main outcome was the change in International Prostate Symptom Score (IPSS) after PAE versus TURP. Secondary outcomes included patient-reported outcomes, functional measures, and adverse events assessed at baseline and at 3, 6, 12, 24, and 60 mo. Between-group differences in the change from baseline to 5 yr were tested using two-sided Mann-Whitney and t tests. KEY FINDINGS AND LIMITATIONS: Of the 103 patients with refractory LUTS/BPO who were randomised between 2014 and 2017, 18/48 who underwent PAE and 38/51 who underwent TURP reached the 60-mo follow-up visit. The mean reduction in IPSS from baseline to 5 yr was -7.78 points after PAE and -11.57 points after TURP (difference 3.79 points, 95% confidence interval [CI] -0.66 to 8.24; p = 0.092). TURP was superior for most patient-reported secondary outcomes except for erectile function. At 5 yr, PAE was less effective than TURP regarding objective parameters, such as the improvement in maximum urinary flow rate (3.59 vs 9.30 ml/s, difference -5.71, 95% CI -10.72 to -0.70; p = 0. 027) and reduction in postvoid residual volume (27.81 vs 219.97 ml; difference 192.15, 95% CI 83.79-300.51; p = 0.001). CONCLUSIONS AND CLINICAL IMPLICATIONS: The improvement in LUTS/BPO at 5 yr after PAE was inferior to that achieved with TURP. The limitations of PAE should be considered during patient selection and counselling. PATIENT SUMMARY: In this study, we show the long-term results of prostate artery embolisation (PAE) in comparison to transurethral resection of the prostate (TURP) for the treatment of benign prostate enlargement causing urinary symptoms. PAE shows good long-term results in properly selected patients, although the improvements are less pronounced than with TURP. This trial is registered on ClinicalTrials.gov as NCT02054013.
RESUMEN
PURPOSE: To assess efficacy and safety of prostatic artery embolization (PAE) in patients with advanced prostate cancer (PCa). MATERIALS AND METHODS: In this prospective single-center, single-arm, pilot study, 9 men with advanced PCa underwent PAE. PAE was performed with the use of 250-400 µm Embozene microspheres (Boston Scientific, Natick, Massachusetts, USA). International Prostate Symptoms Score (IPSS), urinary peak flow (Qmax) and post-void residual urine volume (PVR) was assessed at 12 weeks and up to 12 months. Changes in total prostate volume (TPV) and tumor responses by PSA, changes in tumor volume and evaluation of tumor regression by multiparametric magnetic resonance imaging were assessed at 12 weeks after PAE. RESULTS: IPSS reduction in median 6 points (0-19) and a significant decrease in PVR from median 70 (20-600) mL to 10 (0-280) mL could be achieved within 12 weeks after PAE. Median TPV and tumor volumes (TV) increased slightly from 19.7 (6.4-110.8) mL to 23.4 (2.4-66.3) mL and 6.4 (4.6-18.3) mL to 8.1 (2.4-25.6) mL at a median of 12 weeks after the procedure. Significant tumor necrosis (≥ 50%) was found in one patient. Eight patients showed > 50% of viable tumor on post-PAE MRI according to MRI. Only one Clavien-Dindo Grade 1 adverse event related to PAE occurred. CONCLUSIONS: PAE with the use of 250-400 µm microspheres is feasible, safe and effective in some patients with advanced PCa regarding functional outcomes. A cytoreductive effect might be achieved in individual patients but must be further assessed. TRIALS REGISTRATION: NCT03457805.

CONTEXT: Prostatic artery embolization (PAE) is increasingly performed worldwide for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic obstruction (BPO). In contrast, the role of PAE in patients with prostate cancer (PCa) is unclear. OBJECTIVE: This systematic review summarizes the current available literature on PAE in patients with PCa regarding oncological and functional outcome. EVIDENCE ACQUISITION: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) recommendations. A structured search for the relevant literature from 1985 to 2022 was performed in Medline, Embase, and York CRD. Risk of bias and confounding assessments were performed using the ROBINS tool. EVIDENCE SYNTHESIS: Thirteen trials (12 case series and one animal study using a canine model) were included in this systematic review. Four studies had a prospective study design. The risk of bias was rated moderate to serious in all the studies. CONCLUSIONS: PAE in patients with PCa seems to be a safe procedure and effective regarding the improvement of LUTS. Despite PAE having been shown to be feasible in different treatment scenarios of localized or advanced PCa, the oncological benefits are debatable due to an unreliable tumor response and a lack of controlled trials including long-term follow-up. PATIENT SUMMARY: We investigated the literature to determine the role of prostatic artery embolization (PAE) in patients with prostate cancer regarding oncological and functional outcomes. The results suggest a similar safety profile and efficacy in terms of functional outcomes to those reported earlier for PAE in patients with lower urinary tract symptoms due to benign prostatic hyperplasia. The role of PAE regarding oncological outcomes has to be assessed further.
RESUMEN
We describe the first case of a spindle cell/pleomorphic lipoma of the seminal vesicle. A 6.2cm large mass originating from the left seminal vesicle was incidentally detected on imaging for peripheral arterial disease. A transrectal ultrasound-guided biopsy was negative for malignancy. We proceeded with a robotic tumor resection due to the size of the mass and sarcomatoid features present on MR imaging. The final pathological work-up revealed a spindle cell/pleomorphic lipoma, immunohistochemical staining was performed with no malignant features detected, in particular no signs of an atypical lipomatous tumor. Ejaculatory function was preserved with reduced volume at 6-weeks follow-up.
RESUMEN
PURPOSE: To determine self-assessed goal achievement (SAGA) outcomes in men treated surgically for lower urinary tract symptoms (LUTS) due to benign prostatic obstruction (BPO) and compare them to the traditional outcome measures. METHODS: Single-center analysis of prospective database of men undergoing surgical treatment of LUTS/BPO at a single institution between July 2019 and March 2021. We assessed individual goals, traditional questionnaires, and functional outcomes prior to treatment, and at first follow-up after 6-12 weeks. We compared SAGA outcomes 'overall goal achievement' and 'satisfaction with treatment' to subjective and objective outcomes using Spearman's rank correlations (rho). RESULTS: A total of sixty-eight patients completed the individual goal formulation prior to surgery. Preoperative goals varied between different treatments and individuals. IPSS correlated with 'overall goal achievement' (rho = - 0.78, p < 0.001) and 'satisfaction with treatment' (rho = - 0.59, p < 0.001). Similarly, the IPSS-QoL was correlated with overall goal achievement (rho = - 0.79, p < 0.001) and satisfaction with treatment (rho = - 0.65, p < 0.001). No correlation was seen between SAGA outcomes and functional outcomes Qmax and PVR. CONCLUSIONS: SAGA represents a uniquely patient-specific outcome measure. Our study is, to our knowledge, the first to assess patient-specific goals prior to surgery and examine SAGA outcomes following treatment in men suffering from LUTS/BPO. The correlation of SAGA outcomes with IPSS and IPSS-QoL highlight the importance of this well-established questionnaire. Functional outcomes do not necessarily reflect patient's goals and may rather be considered physician-directed outcomes.

Female urethral stricture is a rare manifestation of bladder outlet obstruction in women. According to the current guidelines of the European Association of Urology, urethral dilatation should be offered as first line treatment. Intermittent self-dilatation (ISD) in case of recurrence is recommended. However, if patients wish definitive surgical treatment or are not able to perform ISD, urethroplasty can be considered. So far, there are little data available on urethroplasty in female patients. We present a case of a 44-year old female patient with a postoperative urethral stricture who underwent ventral-inlay buccal mucosal graft urethroplasty due to inability to perform ISD.
RESUMEN
Background: Structured curricula are demanded to improve training programs of future urologists. This study aimed to evaluate the acceptance of the newly implemented residency rotation program at the University Hospital Frankfurt. Primary endpoint was resident's satisfaction with the current residency rotation program. Secondary endpoint was the fulfilment of the objectives and expectations by residents. Methods: A standardized 15-item, online-based survey was sent to every urologic resident of the University Hospital Frankfurt, completing their rotation between August 2020 and August 2022. In addition to baseline characteristics, training and working conditions were assessed. Descriptive statistics were applied. Results: In total 15 rotations of the Residency Rotation Program at the University Hospital Frankfurt were evaluated, including urologic practice (5/15), Intermediate Care Unit (4/15), urooncology (4/15) and clinical exchange to St. Gallen (2/15). Overall, the majority were very (67%) or rather satisfied (2%) with their rotation. Of the pre-rotation defined objectives, 71% were fulfilled, 18% partially fulfilled and 8% not fulfilled. With respect to the expectations, 67% were fulfilled, 19% partly fulfilled and 4% were not fulfilled. All residents would recommend their respective rotations. Conclusion: Our results demonstrate that the residency rotation program at the University Hospital Frankfurt enjoys a high level of acceptance as well as a positive impact on urologic training. Satisfaction with the completed rotation was convincing, most of the expectations and objectives for the respective rotation could be fulfilled. These results help to ensure the quality of urologic curricula and to improve the structure of training programs for future urologists.
RESUMEN
Paraganglioma (PGL) of the urinary bladder are a very rare tumor entity. Treatment of a PGL requires a multidisciplinary approach. We report on a case of a malignant pheochromocytoma (PHEO) of the bladder in a male adult due to a succinate dehydrogenase B (SDHB) subunit gene mutation where a partial cystectomy was perfomed after preoperative alpha blocking.
RESUMEN
PURPOSE: To compare in-hospital treatment costs of aquablation and transurethral resection of the prostate (TURP) in the treatment of benign prostatic enlargement. PATIENTS AND METHODS: Patient data and procedural details were derived from a prospective database. In-hospital costs were calculated using detailed expenditure reports provided by the hospital accounts department. Total costs including those arising from surgical procedures, consumables, personnel and accommodation were analysed for 24 consecutive patients undergoing aquablation and compared with 24 patients undergoing TURP during the same period. Mean total costs and mean costs for individual expense items were compared between treatment groups with t-tests. RESULTS: Mean total costs per patient (± standard deviation) were higher for aquablation at EUR 10,994 ± 2478 than for TURP at EUR 7445 ± 2354. The mean difference of EUR 3549 was statistically significant (p <0.001). Although the mean procedural costs were significantly higher for aquablation (mean difference EUR 3032; p <0.001), costs apart from the procedure were also lower for TURP, but the mean difference of EUR 1627 was not significant (p <0.327). Medical supplies were mainly responsible (mean difference EUR 2057; p <0.001) for the difference in procedural costs. CONCLUSIONS: In-hospital costs are significantly higher for aquablation than for TURP, mainly due to higher costs of medical supplies for the procedure. This difference should be taken into consideration, at least in patients for whom the different side effect profiles of both treatments are irrelevant.

Prostatic artery embolisation (PAE) is now endorsed by international evidence-based guidelines as a treatment for lower urinary tract symptoms presumed secondary to benign prostatic obstruction (LUTS/BPO) for selected patients. PAE is a truly minimally invasive technique, with proven efficacy and safety demonstrated for the short- to mid-term. As it has a unique treatment approach (endovascular instead of transurethral), its profile and ideal application differ clearly from other treatments for LUTS/BPO, which must be considered for patient selection. This mini review examines the role of PAE in the treatment of LUTS/BPO on the basis of current evidence. PATIENT SUMMARY: For properly selected patients, prostatic artery embolisation (PAE), in which arteries feeding the prostate are blocked in a nonsurgical procedure, is one of the treatment options for obstruction of urine outflow caused by benign enlargement of the prostate. This article examines the role of PAE according to the evidence available in the literature.

BACKGROUND: Penile cancer represents a rare malignant disease, whereby a small caseload is associated with the risk of inadequate treatment expertise. Thus, we hypothesized that strict guideline adherence might be considered a potential surrogate for treatment quality. This study investigated the influence of the annual hospital caseload on guideline adherence regarding treatment recommendations for penile cancer. METHODS: In a 2018 survey study, 681 urologists from 45 hospitals in four European countries were queried about six hypothetical case scenarios (CS): local treatment of the primary tumor pTis (CS1) and pT1b (CS2); lymph node surgery inguinal (CS3) and pelvic (CS4); and chemotherapy neoadjuvant (CS5) and adjuvant (CS6). Only the responses from 206 head and senior physicians, as decision makers, were evaluated. The answers were assessed based on the applicable European Association of Urology (EAU) guidelines regarding their correctness. The real hospital caseload was analyzed based on multivariate logistic regression models regarding its effect on guideline adherence. RESULTS: The median annual hospital caseload was 6 (interquartile range (IQR) 3-9). Recommendations for CS1-6 were correct in 79%, 66%, 39%, 27%, 28%, and 28%, respectively. The probability of a guideline-adherent recommendation increased with each patient treated per year in a clinic for CS1, CS2, CS3, and CS6 by 16%, 7.8%, 7.2%, and 9.5%, respectively (each p < 0.05); CS4 and CS5 were not influenced by caseload. A caseload threshold with a higher guideline adherence for all endpoints could not be perceived. The type of hospital care (academic vs. non-academic) did not affect guideline adherence in any scenario. CONCLUSIONS: Guideline adherence for most treatment recommendations increases with growing annual penile cancer caseload. Thus, the results of our study call for a stronger centralization of diagnosis and treatment strategies regarding penile cancer.
RESUMEN
INTRODUCTION: Male reproductive health is rapidly declining during the past decades and it is well known that scrotal temperature is linked to male infertility. MATERIAL AND METHODS: We performed a prospective data evaluation within a counterfactual analysis study design. Scrotal cooling was performed using Snowballs™ underwear, scrotal temperature was monitored using a wireless temperature sensor (SensorPush, Brooklyn, NY, 11215). RESULTS: Overall, scrotal skin temperatures were monitored for 1008 hours. Median scrotal skin temperature was 34.6°C (IQR 33.1 to 35.3) and 35.3°C (IQR 34.4 to 35.9) in the experimental (SnowWedge™) period and control period, respectively, which was significantly different (P <0.001). CONCLUSIONS: Cyclic scrotal skin cooling using specialized underwear is feasible and efficacious without impairing the activities of daily living and reduces median scrotal skin temperature significantly by 0.7°C. Given the proven association of scrotal skin temperature and semen quality, cyclic scrotal skin cooling by a device such as Snowballs™ underwear may eventually increase semen quality and fertility.
RESUMEN
As multiple different treatment options are available for prostate cancer (PCa) and YouTube is commonly used as a source for medical information, we performed a systematic and comparative assessment of available videos guiding patients on their choice for the optimal treatment. An independent search for surgical therapy or radiotherapy of PCa on YouTube was performed and the 40 most viewed videos of both groups were analyzed. The validated DISCERN questionnaire and PEMAT were utilized to evaluate their quality and misinformation. The median overall quality of the videos was found to be low for surgery videos, while radiotherapy videos results reached a moderate quality. The median PEMAT understandability score was 60% (range 0-100%) for radiotherapy and 75% (range 40-100) for surgery videos. The radiotherapy videos contained less misinformation and were judged to be of higher quality. Summarized, the majority of the provided videos offer insufficient quality of content and are potentially subject to commercial bias without reports on possible conflict of interest. Thus, most of available videos on YouTube informing PCa patients about possible treatment methods are not suited for a balanced patient education or as a basis for the patient's decision.

INTRODUCTION: Patients nowadays often search video-sharing platforms for online patient education materials. Since previous assessments of urological videos were limited to English, we systematically assessed the quality of videos on treatment of benign prostatic hyperplasia (BPH), prostate cancer (PCa), and urinary stone disease (USD) in 4 different languages on YouTube using validated instruments. METHODS: The search for videos on YouTube addressing treatment options of BPH, PCa, and USD was performed in October 2020 in -English, French, German, and Italian. Assessed parameters included basic data (e.g., number of views), grade of misinformation, and reporting of conflicts of interest. Quality of content was analyzed using the validated DISCERN questionnaire. Data were analyzed using descriptive statistics. RESULTS: A total of 240 videos (60 videos in each language) were analyzed. Videos on USD in English had the highest number of views (median views 271,878 [65,313-2,513,007]). The median overall quality of videos assessed showed a moderate quality (2.5-3.4 points out of 5 points for DISCERN item 16). Median total DISCERN score of all videos divided by language showed very similar results: English (39.75 points), French (38 points), German (39.5 points), and Italian (39 points). Comparing the different diseases, videos about BPH showed the highest median scores, especially in German language (median score 43.25 points). CONCLUSIONS: Videos concerning the treatment of BPH, PCa, and USD have a low to moderate quality of content, with no differences seen between the languages assessed. These findings further support the notion of improved patient information materials on video platforms such as YouTube.

INTRODUCTION: A novel method for the surgical treatment of benign prostatic hyperplasia (BPH) called Aquablation has become commercially available. Previous studies have been able to show similar functional results when compared with transurethral resection of the prostate and a high efficacy has been demonstrated when this approach is applied to patients with a prostate size of 80-150 cm3.Holmium laser enucleation of the prostate (HoLEP) is a well-established procedure in the surgical treatment of BPH in prostate glands larger than 30 mL and a first-line therapy in glands over 80 mL. To date, no data are available whether Aquablation is non-inferior compared with HoLEP in the treatment of patients with medium-to-large-sized prostates regarding safety and efficacy. METHODS AND ANALYSIS: This is a prospective, randomised, open-label, non-inferiority clinical trial conducted at a Swiss centre of tertiary care. The primary outcome is assessment of non-inferiority of Aquablation compared with HoLEP in reducing lower urinary tract symptoms due to benign prostatic obstruction measured by the International Prostate Symptom Score (IPSS). Randomisation will be performed using secuTrial, stratifying on age (<70 years, 70+ years) and prostate volume (<100 mL, 100+ mL). Both interventions are performed in an inpatient setting and regular follow-up controls starting 8 weeks after intervention and continuing up to 5 years will be performed. The primary outcome (change in IPSS from baseline to 6 months) will be tested for non-inferiority with a one-sided t-test. Secondary outcomes, such as efficacy parameters, several patient-reported outcome measures, and periprocedural and safety parameters will be described by calculating means or relative frequencies for each treatment group and testing differences with two-sided standard superiority tests. ETHICS AND DISSEMINATION: The study was approved by the local ethics committee (EKOS 2020-02353). Results of the primary endpoint and each of the secondary endpoints will be published in an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT04560907).

Wetland methane (CH4) emissions ([Formula: see text]) are important in global carbon budgets and climate change assessments. Currently, [Formula: see text] projections rely on prescribed static temperature sensitivity that varies among biogeochemical models. Meta-analyses have proposed a consistent [Formula: see text] temperature dependence across spatial scales for use in models; however, site-level studies demonstrate that [Formula: see text] are often controlled by factors beyond temperature. Here, we evaluate the relationship between [Formula: see text] and temperature using observations from the FLUXNET-CH4 database. Measurements collected across the globe show substantial seasonal hysteresis between [Formula: see text] and temperature, suggesting larger [Formula: see text] sensitivity to temperature later in the frost-free season (about 77% of site-years). Results derived from a machine-learning model and several regression models highlight the importance of representing the large spatial and temporal variability within site-years and ecosystem types. Mechanistic advancements in biogeochemical model parameterization and detailed measurements in factors modulating CH4 production are thus needed to improve global CH4 budget assessments.
RESUMEN
PURPOSE: Aside from urological and sexual problems, long-term (≥5 years after initial diagnosis) prostate cancer (PC) survivors might suffer from pain, fatigue, and depression. These concurrent symptoms can form a cluster. In this study, we aimed to investigate classes of this symptom cluster in long-term PC survivors, to classify PC survivors accordingly, and to explore associations between classes of this cluster and health-related quality of life (HRQoL). METHODS: Six hundred fifty-three stage T1-T3N0M0 survivors were identified from the Prostate Cancer Survivorship in Switzerland (PROCAS) study. Fatigue was assessed with the EORTC QLQ-FA12, depressive symptoms with the MHI-5, and pain with the EORTC QLQ-C30 questionnaire. Latent class analysis was used to derive cluster classes. Factors associated with the derived classes were determined using multinomial logistic regression analysis. RESULTS: Three classes were identified: class 1 (61.4%) - "low pain, low physical and emotional fatigue, moderate depressive symptoms"; class 2 (15.1%) - "low physical fatigue and pain, moderate emotional fatigue, high depressive symptoms"; class 3 (23.5%) - high scores for all symptoms. Survivors in classes 2 and 3 were more likely to be physically inactive, report a history of depression or some other specific comorbidity, be treated with radiation therapy, and have worse HRQoL outcomes compared to class 1. CONCLUSION: Three distinct classes of the pain, fatigue, and depression cluster were identified, which are associated with treatment, comorbidities, lifestyle factors, and HRQoL outcomes. Improving classification of PC survivors according to severity of multiple symptoms could assist in developing interventions tailored to survivors' needs.

OBJECTIVE: To retrospectively investigate the safety of magnetic resonance imaging (MRI) in patients under sacral neuromodulation (InterStim II). METHODS: Data of patients who received a sacral neuromodulator at the urological department of a Swiss center of tertiary care from 2007 to 2018 and subsequently received at least 1 MRI with implanted device were retrospectively analyzed. Patient characteristics, data on implantation, MRI characteristics and complications potentially related to the MRI were analyzed. In addition, patient interviews were performed to verify the data gathered from patient records. RESULTS: A total of 55 consecutive patients with a median age of 48 years (range 16 - 80 years) and a total of 191 MRIs (median 3, range 1 - 13) were included to the study. The majority of MRIs (92%) were performed with 1.5 Tesla. The majority of the 1.5 Tesla (58%) as well as 3 Tesla (56%) MRIs assessed body regions other than the head. Complication possibly related to the MRI were only found in 2 (1%) MRI scans in two patients who reported on transient electrifying pain and heat sensation at the implantation site of the neuromodulator during MRI. CONCLUSION: MRI scans in patients with an implanted InterStim II sacral neuromodulator and with the device being turned off seem to be safe, even if they involve body regions other than the head, at least with 1.5 Tesla.
