ABSTRACT Purpose: To compare biochemical recurrence, sexual potency and urinary continence outcomes of ablative therapy and radical treatment (radical prostatectomy or radiotherapy with androgen deprivation therapy). Material and methods: A systematic review and meta-analysis followed the PRISMA guidelines were performed. We searched MEDLINE/PubMed. Biochemical recurrence at three and five years; incontinence rate (patients who used one pad or more) and erectile dysfunction rate at 12 and 36 months (patients who did not have sufficient erection to achieve sexual intercourse) were evaluated. The Mantel-Haenszel method was applied to estimate the pooled risk difference (RD) in the individual studies for categorical variables. All results were presented as 95% confidence intervals (95%CI). Random effects models were used regardless of the level of heterogeneity (I²). (PROSPERO CRD42022296998). Results: Eight studies comprising 2,677 men with prostate cancer were included. There was no difference in biochemical recurrence between ablative and radical treatments. We observed the same biochemical recurrence between ablative therapy and radical treatment within five years (19.3% vs. 16.8%, respectively; RD 0.07; 95%CI=-0.05, 0.19; I2=68.2%; P=0.08) and continence rate at 12 months (9.2% vs. 31.8%, respectively; RD −0.13; 95%CI, −0.27, 0.01; I2=89%; P=0.32). When focal treatment was analyzed alone, two studies with 582 patients found higher erectile function at 12 months in the ablative therapy group than in the radical treatment (88.9% vs. 30.8%, respectively; RD −0.45; 95%CI −0.84, −0.05; I2=93%; P=0.03). Conclusion: Biochemical recurrence and urinary continence outcomes of ablative therapy and radical treatment were similar. Ablative therapy appears to have a high rate of sexual potency.

ABSTRACT Introduction: Historically, therapeutic avenues for patients with clinical stage II seminoma germ cell tumors (SGCT) were confined to radiotherapy and chemotherapy. While survival rates with these modalities are commendable, both entail substantial long-term morbidities. Furthermore, this youthful patient cohort exhibits elevated rates of secondary malignancies, surfacing decades post-successful primary cancer treatment (1). Recently, retroperitoneal lymph node dissection (RPLND) has emerged as a primary treatment consideration for individuals with low-volume metastatic seminoma (2–4). However, there is a dearth of video documentation illustrating the robotic assisted (RA) bilateral approach (5- 7). Methods: We present the case of a 24-year-old male who underwent prior left orchiectomy for seminoma (pT1b). Despite negative serum tumor markers, a 1.7 x 1.4cm lymph node enlargement was identified in the aortic bifurcation after 4 months, classifying the patient as stage IIA per the IGCCCG risk classification. Subsequently, a RA bilateral template RPLND was performed due to the patient's refusal of chemotherapy, citing concerns about offspring. Results: The surgery was performed, incorporating nerve sparing techniques, lasting 4h13minutes, an estimated bleeding rate of 400ml, without intraoperative complications. The patient was discharged within 24 hours of the procedure, following a prescribed low-fat diet. Conclusion: The patient experienced postoperative well-being, painlessness, and resumed work three weeks post-procedure. Preserved ejaculation was noted, and adjuvant therapy was performed with 2 cycles of EP due to the anatomopathological result. The feasibility of robotic primary RPLND for SGCT was demonstrated, showing reduced postoperative pain and early hospital discharge. Further studies are necessary to validate our findings regarding oncological, safety, and functional outcomes.

ABSTRACT Objective: To study the efficacy of tranexamic acid at reducing bleeding during bipolar prostate resection surgery (B-TURP) in patients with benign prostatic hyperplasia. Methods: We searched registers with MESH terms "prostate hyperplasia," "prostate surgery," and "tranexamic acid." Studies available in full and online, published from 2013 to 2023, in Portuguese, English, Spanish, and French were included; review articles were excluded. Information sources: Portal Regional da Biblioteca Virtual em Saúde and PubMed Central. The Cochrane RoB2 tool was used to analyze risk of bias in randomized clinical trials. Results: Two randomized clinical trials involving 256 patients were included. Both groups had minimal risk of bias. Both studies showed a positive effect of tranexamic acid on blood loss parameters. Only one study in the tranexamic acid group had a lower transfusion rate, and another had a lower irrigation fluid volume and operation time in the tranexamic acid group. A meta-analysis was not performed because of the limited number of eligible studies. Conclusion: For patients undergoing B-TURP for benign prostatic hyperplasia symptoms, the use of tranexamic acid reduced blood loss. However, a limited number of patients were studied, and the available randomized clinical trials presented conflicting conclusions. Therefore, further studies are needed to explore this aspect in detail. Prospero database registration: (www.crd.york.ac.uk/prospero) under registration ID CRD42023416383.

ABSTRACT Introduction To evaluate the possible effects of the coronavirus disease 2019 (COVID-19) pandemic on the oncologic results of patients with prostate cancer regarding clinical staging, presence of adverse pathological outcomes, and perioperative complications. Materials and methods This retrospective study included patients who underwent radical prostatectomy. The time between biopsy and surgery, staging tests, final histopathological evaluation after surgery, lymphadenectomy rate, postoperative complications, and prostatic specific antigen (PSA) levels (initial and 30 days after surgery) were analyzed and compared in a group of patients before and during the pandemic period. Results We included 226 patients: 88 in the pre-pandemic period and 138 during the pandemic period. There was no statistically significant difference in mean age, body mass index, ASA, pathological locally advanced disease, the proportion of patients who underwent lymphadenectomy, and ISUP grade in the biopsy between the groups. Positive surgical margins, prostatic extracapsular extension, and PSA levels at 30 days were also similar between the groups. The mean time between medical consultation and surgery was longer in the pandemic period than in the pre-pandemic (124 vs. 107 days, p<0.001), and the mean time between biopsy and medical consultation (69.5 days vs. 114 days, p<0.001) and between biopsy and surgery (198.5 days vs. 228 days, p=0.013) was shorter during the pandemic. The incidence of severe early and late perioperative complications was similar between the periods. Conclusions There was no delay between diagnosis and treatment at our institution during the COVID-19 pandemic period. No worsening of the prostate cancer features was observed. 201 COVID19 COVID 19 (COVID-19 outcomes prostatectomy tests rate (PSA initial 3 22 8 prepandemic pre 13 age index ASA groups margins extension 124 (12 vs 10 p<0.001, p0001 p p<0.001 , 0 001 69.5 695 69 5 (69. 11 198.5 1985 198 (198. p=0.013 p0013 013 periods COVID-1 observed 20 COVID1 1 (COVID-1 2 12 (1 p000 p<0.00 00 69. 6 (69 198.

ABSTRACT Introduction: We aimed to evaluate the role of remote proctoring during the initial training phases of a robotics curriculum using surgical robot skills simulator exercises. Materials and Methods: Prospective randomized study comprising 36 urology residents and junior staff urologists without previous robotic training. Group 1 (G1) performed exercises without any assistance or support, group 2 (G2) received support from in-person proctor, and group 3 (G3) from a remote proctor through a telementoring system. Qualitative and quantitative analyses were conducted for each exercise and group. Results: The overall score approval rates (OSA) for the different skill exercises were Ring Walk 2 (RW2) 83%, Energy Dissection 2 (ED2) 81%, and Ring Walk 3 (RW3) 14%. RW2 OSA was higher on attempt 3 than on attempt 1 (83.3% vs. 63.9%, p=0.032). ED2 OSA rate was higher in attempt 3 than in attempt 1 (80.6% vs. 52.8%, p=0.002). RW2 OSA was similar among the groups. In ED2, both remote and live assistance were significantly related to upper OSA (G1=47.2%, G2=75.0%, G3=83.3%, p=0.002). RW3 had similar OSA among the groups, which can be explained by the high level of difficulty and low OSA in all the groups. However, in a sensitive quantitative analysis, the mean overall score of the participants in RW3 was higher in both proctored groups (G1=24, G2=57.5, G3=51.5, p=0.042). Conclusion: Robotic performance increased significantly over three attempts for simulation exercises of low, medium, but not high-complexity. Proctoring, either in-person or remotely, has a positive impact on approval performance, particularly in intermediate tasks.

ABSTRACT Objective To analyze the characteristics of public health services related to radical prostatectomy, according to hospital volume of surgeries and stratified as academic and non-academic centers. Methods An ecological study was conducted using a database available in TabNet platform of the Unified Health System Department of Informatics. Number of surgeries, length of hospital stay, length of stay in intensive care unit, in-hospital mortality rate, and cost of hospitalization were evaluated. The hospitals were divided into three subgroups according to surgery volume (tercile), and results were compared. The same comparisons were made among academic and non-academic centers. We considered academic centers those providing Urology residency program. Results A total of 11,259 radical prostatectomies were performed in the city of São Paulo between 2008 and 2018. We observed a significant trend of increase in radical prostatectomies for treating prostate cancer over the years (p=0.007). The length of stay in intensive care unit, and number of deaths were not statistically different among centers with diverse surgery volume, nor between academic and non-academic centers. However, length of hospital stay was significantly shorter in academic centers (p=0.043), while cost of hospitalization was significantly higher in high-volume center compared to low- (p<0.001) and intermediate-volume centers (p<0.001). Conclusion Length of hospital stay for radical prostatectomies performed in public services in the city of São Paulo was shorter in academic centers, whereas hospitals with a high volume of surgeries showed greater cost of hospitalization.

RESUMO Introdução: o tratamento do câncer de adrenal benigno (hormonalmente ativo ou não funcional) e maligno inclui a adrenalectomia. A experiência dos cirurgiões e a cirurgia realizada por cirurgiões de alto volume foram associadas a menos complicações e menor custo. O objetivo do estudo foi descrever e comparar o número de cirurgias, a taxa de mortalidade e o tempo de internação para adrenalectomias realizadas entre 2008 e 2019 na rede pública de saúde de São Paulo. Métodos: trata-se de um estudo ecológico. Os dados foram coletados da Plataforma TabNet do Departamento de Informática do Sistema Único de Saúde. Os hospitais foram divididos em três subgrupos de acordo com o volume cirúrgico e hospitais com e sem programa de residência médica em Urologia. Os resultados foram comparados entre os grupos. Resultados: no período estudado, 943 adrenalectomias foram realizadas em São Paulo. As taxas de mortalidade durante a internação de acordo com o volume cirúrgico hospitalar foram: não foram relatados óbitos em hospitais de baixo volume; 0,015% em hospitais de volume intermediário e 0,004% em alto volume. O tempo médio de permanência na UTI foi de 1,03 dias nos hospitais de baixo volume; 2,8 nos de médio volume e 1,12 nos de alto volume (análise entre centros de médio e alto volume com significância estatística, p=0,016). Conclusão: as taxas de mortalidade foram muito baixas em todos os grupos. A permanência na UTI foi menor em centros de alto volume do que em centros de volume intermediário.

ABSTRACT Introduction: treating benign (hormonally active or nonfunctional) and malignant adrenal cancer includes adrenalectomy. The expertise of surgeons and surgery performed by high-volume surgeons were associated with fewer complications and lower cost. We aimed to describe and compare the number of surgeries, mortality rate, and length of hospital stay for adrenalectomies performed between 2008 and 2019 in the public health system of São Paulo. Methods: this was an ecological study. The data were collected using the TabNet Platform of the Unified Health System Department of Informatics. Outcomes analyzed included the number of surgeries performed, mortality rate during hospital stay, and length of hospital stay. Public hospitals in Sao Paulo were divided into three subgroups according to the surgical volume of adrenalectomies performed as well as hospitals with and without a residency program in Urology, and the results were compared among them. Results: a total of 943 adrenalectomies were performed in Sao Paulo between 2008 and 2019. Mortality rates during hospital stay according to hospital surgical volume were no reported deaths in low-volume, 0.015% in intermediate-volume, and 0.004% in high-volume hospitals. The average length of the ICU stay was 1.03 days in low-volume, 2.8 in intermediate-volume, and 1.12 in high-volume hospitals (analysis between intermediate and high volume centers with statistical significance, p=0.016). Conclusions: despite no statistically significant differences among the groups analyzed, mortality rates were very low in all groups. ICU stay was shorter in high-volume centers than in intermediate-volume centers.

ABSTRACT Objective To evaluate the predictive value of positron emission computed tomography or magnetic resonance (PET-CT and PET-MRI) using gallium-68-labeled prostate-specific membrane antigen (68Ga-PSMA) in lymph node involvement in prostate cancer. Methods A retrospective study comprising 91 patients diagnosed with prostate cancer between 2016 to 2020, who underwent 68Ga-PSMA PET-CT or PET-MRI for staging before prostatectomy. The patients were divided into Group 1, with 65 patients with satisfactory pathological lymph node analysis, and Group 2, with 91 patients representing the sum of patients with pathological lymph node analysis and those with postoperative prostate-specific antigen within 60 days after surgery. Receiver Operating Characteristic curves were used to assess accuracy of predictive capacity of imaging exams for lymph node involvement. Results Regarding local clinical staging, the groups showed similar results, and 50% were classified as staging T2a. The accuracy of 68Ga-PSMA PET-CT for prostate cancer lymph node staging was 86.5% (95%CI 0.74-0.94; p=0.06), with a sensitivity of 58.3% and specificity of 95%. The accuracy of 68Ga-PSMA PET-MRI was 84.6% (95%CI 0.69-0.94; p=0.09), with a sensitivity of 40% and specificity of 100%. Considering both 68Ga-PSMA PET-CT and PET-MRI, the accuracy was 85.7% (95%CI 0.76-0.92; p=0.015), with sensitivity of 50% and specificity of 97%. Conclusion The imaging tests 68Ga-PSMA PET-CT and PET-MRI were highly accurate to detect preoperative lymph node involvement, and could be useful tools to indicate the need for extended lymph node dissection during radical prostatectomy.

ABSTRACT Objective To describe and compare the number of surgeries, mortality rate, length of hospital stay, and costs of transurethral resection of the prostate and open prostatectomy for the treatment of benign prostatic hyperplasia, between 2008 and 2018, in the Public Health System in São Paulo, Brazil. Methods Ecological and retrospective study using data from the informatics department of the Brazilian Public Health System database. Procedure codes were “open prostatectomy” and “transurethral resection of the prostate.” The outcomes analyzed were compared between transurethral resection of the prostate and open prostatectomy according to the hospital surgical volume and presence or absence of a residency program. Results A total of 18,874 surgeries were analyzed (77% transurethral resection of the prostate) and overall mortality was not statistically different between procedures. Intermediate and high-volume centers had shorter length of hospital stay than low-volume centers for transurethral resection of the prostate (3.28, 3.02, and 6.58 days, respectively, p=0.01 and p=0.004). Length of hospital stay was also shorter for open prostatectomy in high-volume compared to low-volume centers (4.86 versus 10.76 days, p=0.036). Intrahospital mortality was inversely associated with surgical volume for transurethral resection of the prostate. Centers with residency program had shorter length of hospital stay considering open prostatectomy and less mortality regarding transurethral resection of the prostate. Open prostatectomy was 64% more expensive than transurethral resection of the prostate. Conclusion The findings suggest the importance of investing in specialized centers, which could be potential referral centers for surgical cases.

ABSTRACT Background: Non-metastatic castration resistant prostate cancer (M0 CRPC) has seen important developments in drugs and diagnostic tools in the last two years. New hormonal agents have demonstrated improvement in metastasis free survival in M0 CRPC patients and have been approved by regulatory agencies in Brazil. Additionally, newer and more sensitive imaging tools are able to detect metastasis earlier than before, which will impact the percentage of patients staged as M0 CRPC. Based on the available international guidelines, a group of Brazilian urology and medical oncology experts developed and completed a survey on the diagnosis and treatment of M0 CRPC in Brazil. These results are reviewed and summarized and associated recommendations are provided. Objective: To present survey results on management of M0 CRPC in Brazil. Design, setting, and participants: A panel of six Brazilian prostate cancer experts determined 64 questions concerning the main areas of interest: 1) staging tools, 2) treatments, 3) side effects of systemic treatment/s, and 4) osteoclast-targeted therapy. A larger panel of 28 Brazilian prostate cancer experts answered these questions in order to create country-specific recommendations discussed in this manuscript. Outcome measurements and statistical analysis: The panel voted publicly but anonymously on the predefined questions. These answers are the panelists' opinions, not a literature review or meta-analysis. Therapies not yet approved in Brazil were excluded from answer options. Each question had five to seven relevant answers including two non-answers. Results were tabulated in real time. Conclusions: The results and recommendations presented can be used by Brazilian physicians to support the management of M0 CRPC patients. Individual clinical decision making should be supported by available data, however, for Brazil, guidelines for diagnosis and management of M0 CRPC patients have not been developed. This document will serve as a point of reference when confronting this disease stage.

ABSTRACT Background Focal therapy (FT) for localized prostate cancer (PCa) treatment is raising interest. New technological mpMRI-US guided FT devices have never been compared with the previous generation of ultrasound-only guided devices. Materials and Methods We retrospectively analyzed prospectively recorded data of men undergoing FT for localized low- or intermediate-risk PCa with US- (Ablatherm®-2009 to 2014) or mpMRI-US (Focal One®-from 2014) guided HIFU. Follow-up visits and data were collected using internationally validated questionnaires at 1, 2, 3, 6 and 12 months. Results We included n=88 US-guided FT HIFU and n=52 mpMRI-US guided FT HIFU respectively. No major baseline differences were present except higher rates of Gleason 3+4 for the mpMRI-US group. No major differences were present in hospital stay (p=0.1), catheterization time (p=0.5) and complications (p=0.2) although these tended to be lower in the mpMRI-US group (6.8% versus 13.2% US FT group). At 3 months mpMRI-US guided HIFU had significantly lower urine leak (5.1% vs. 15.9%, p=0.04) and a lower drop in IIEF scores (2 vs. 4.2, p=0.07). Of those undergoing 12-months control biopsy in the mpMRI-US-guided HIFU group, 26% had residual cancer in the treated lobe. Conclusion HIFU FT guided by MRI-US fusion may allow improved functional outcomes and fewer complications compared to US- guided HIFU FT alone. Further analysis is needed to confirm benefits of mpMRI implementation at a longer follow-up and on a larger cohort of patients.
