RESUMEN

BACKGROUND AND OBJECTIVE: A notable paradigm shift has emerged in the choice of prostate biopsy approach, with a transition from transrectal biopsy (TRBx) to transperineal biopsy (TPBx) driven by the lower risk of severe urinary tract infections. The impact of this change on detection of clinically significant prostate cancer (csPCa) remains a subject of debate. Our aim was to compare the csPCa detection rate of TRBx and TPBx. METHODS: Patients who underwent magnetic resonance imaging (MRI)-targeted and systematic biopsies for clinically localized PCa at 15 European referral centers from 2016 to 2023 were included. A propensity score matching (PSM) analysis was performed to minimize selection biases. Logistic regression models were used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs). KEY FINDINGS AND LIMITATIONS: Of 3949 patients who met the study criteria, 2187 underwent TRBx and 1762 underwent TPBx. PSM resulted in 1301 matched pairs for analysis. Patient demographics and tumor characteristics were comparable in the matched cohorts. TPBx versus TRBx was associated with greater detection of csPCa, whether defined as International Society of Urological Pathology grade group ≥2 (51% vs 45%; OR 1.37, 95% CI 1.15-1.63; p = 0.001) or grade group ≥3 (29% vs 23%; OR 1.38, 95% CI 1.13-1.67; p = 0.001). Similar results were found when considering MRI-targeted biopsy alone and after stratifying patients according to tumor location, Prostate Imaging-Reporting and Data System score, and clinical features. Limitations include the retrospective nature of the study and the absence of centralized MRI review. CONCLUSIONS: Our findings bolster existing understanding of the additional advantages offered by TPBx. Further randomized trials to fully validate these findings are awaited. PATIENT SUMMARY: We compared the rate of detection of clinically significant prostate cancer with magnetic resonance imaging (MRI)-guided biopsies in which the sample needle is passed through the perineum or the rectum. Our results suggest that the perineal approach is associated with better detection of aggressive prostate cancer.

RESUMEN

Urology continues its development in minimally invasive surgery, and the year 2023 is marked by important innovations in the different approaches such as endoscopy, laparoscopy, and open surgery. The following innovations are instruments or medical devices which are still being evaluated. What they have in common is a questioning of our current practices, on the technical side but also for some of them on the ecological vision of our profession with the eternal debate of single use or reusable. Even if the evaluation of new devices is primarily medical and medico-economic, it is actually no longer possible to ignore the ecological aspect and the impact on the environment of the various new products. New technologies also make it possible to think about smart connected prostheses and precision intraoperative imaging that can ultimately guide the surgeon's hand.


L'urologie est une spécialité en constante évolution. L'année 2023 a été marquée par le développement de nouveautés en chirurgie minimalement invasive, tant en endoscopie qu'en laparoscopie ou chirurgie ouverte, principalement dans les domaines de la robotique, des technologies connectées, ainsi que dans les instruments médicaux réutilisables. Dans le domaine de l'imagerie, le TEP/CT peropératoire pourrait dans l'avenir guider le geste chirurgical afin d'améliorer les résultats oncologiques. Ces nouvelles technologies permettent le développement de nouveaux instruments ou dispositifs médicaux, dont l'évaluation doit se faire aujourd'hui tant sur le plan médical que socio-économique ou écologique.

RESUMEN

INTRODUCTION AND METHODS: Prostate biopsy (PB) is an essential step in the diagnosis and active surveillance of prostate cancer (PCa). Transperineal PB (TP-PB) is now the recommended approach and is mostly conducted under local anesthesia. However, this procedure can potentially cause anxiety for patients, given the oncological context and the fear of peri-procedural pain and complications. The objective of this narrative review is to summarize the currently available tools for the management of peri-interventional anxiety during TP-PB, with a particular emphasis on the potential role of virtual reality (VR) in this setting. RESULTS: In TP-PB, preoperative anxiety can lead to increased pain perception, longer procedure time, and decreased patient satisfaction. Pharmacological and non-pharmacological approaches have been explored to reduce anxiety, such as premedication, deep sedation, education, relaxation techniques, hypnosis, and music therapy, albeit with mixed results. VR has recently emerged in the technological armamentarium for managing pain and anxiety, and the efficiency of this technology has been evaluated in various medical fields, including pediatrics, gastroenterology, urology, gynecology, and psychiatry. CONCLUSION: Despite the paucity of available data, VR appears to be a safe and effective technique in reducing anxiety in many procedures, even in frail patients. No studies have evaluated the role of VR in TP-PB. Future research should thus explore the optimal way to implement VR technology and any potential benefits for TP-PB patients.

RESUMEN

BACKGROUND: Systematic biopsy (SB) combined with magnetic resonance imaging (MRI)-targeted biopsy is still recommended considering the risk of missing clinically significant prostate cancer (csPCa). OBJECTIVE: To evaluate the added value in csPCa detection on side-specific SB relative to MRI lesion and to externally validate the Noujeim risk stratification model that predicts the risk of csPCa on distant SB cores relative to the index MRI lesion. DESIGN, SETTING, AND PARTICIPANTS: Overall, 4841 consecutive patients diagnosed by MRI-targeted biopsy and SB for Prostate Imaging Reporting and Data System score ≥3 lesions were identified from a prospectively maintained database between January 2016 and April 2023 at 15 European referral centers. A total of 2387 patients met the inclusion criteria and were included in the analysis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: McNemar's test was used to compare the csPCa detection rate between several biopsy strategies including MRI-targeted biopsy, side-specific SB, and a combination of both. Model performance was evaluated in terms of discrimination using area under the receiver operation characteristic curve (AUC), calibration plots, and decision curve analysis. Clinically significant prostate cancer was defined as International Society of Urological Pathology grade group ≥2. RESULTS AND LIMITATIONS: Overall, the csPCa detection rate was 49%. Considering MRI-targeted biopsy as reference, the added values in terms of csPCa detection were 5.8% (relative increase of 13%), 4.2% (relative increase of 9.8%), and 2.8% (relative increase of 6.1%) for SB, ipsilateral SB, and contralateral SB, respectively. Only 35 patients (1.5%) exclusively had csPCa on contralateral SB (p < 0.001). Considering patients with csPCa on MRI-targeted biopsy and ipsilateral SB, the upgrading rate was 2% (20/961) using contralateral SB (p < 0.001). The Noujeim model exhibited modest performance (AUC of 0.63) when tested using our validation set. CONCLUSIONS: The added value of contralateral SB was negligible in terms of cancer detection and upgrading rates. The Noujeim model could be included in the decision-making process regarding the appropriate prostate biopsy strategy. PATIENT SUMMARY: In the present study, we collected a set of patients who underwent magnetic resonance imaging (MRI)-targeted and systematic biopsies for the detection of prostate cancer. We found that biopsies taken at the opposite side of the MRI suspicious lesion have a negligible impact on cancer detection. We also validate a risk stratification model that predicts the risk of cancer on biopsies beyond 10 mm from the initial lesion, which could be used in daily practice to improve the personalization of the prostate biopsy.

RESUMEN

The adoption of robotic-assisted laparoscopic surgery in urology is becoming increasingly frequent. Initially, its use was essentially limited to oncological surgery, such as radical prostatectomy. Its success lies in the enhanced dexterity, the three-dimensional vision, and the ability to easily suture intracorporeally. All these advantages have enabled many pioneer surgeons to develop techniques in the field of functional surgery, such as artificial urinary sphincter implantation and sacrocolpopexy, and as for reconstructive surgery, ureteral reconstructions and enterocystoplasties. This article provides a brief yet rich review of the recently innovated techniques and the now minimally invasive feasibility of previously highly complex procedures in conventional laparoscopy.


L'utilisation de l'assistance robotique en chirurgie laparoscopique est une pratique croissante en urologie, qui s'est généralisée notamment en oncologie. Son succès s'explique par une meilleure ergonomie, une meilleure vision et la capacité à suturer aisément en intracorporel. Ces avantages ont permis à plusieurs équipes de développer des techniques pour des indications de chirurgie fonctionnelle, notamment la pose de sphincter urinaire artificiel, la promontofixation, ainsi qu'en chirurgie reconstructive, par exemple pour les reconstructions urétérales et les entérocystoplasties d'agrandissement. Cet article propose un survol condensé des innovations techniques récentes et de la faisabilité désormais minimalement invasive d'interventions jusqu'à présent hautement complexes en laparoscopie conventionnelle.

RESUMEN

PURPOSE: Patients who undergo robot-assisted laparoscopic radical prostatectomy (RARP) may present concurrent or secondary inguinal hernia (IH). Surgical repair of IH simultaneously with RARP has been reported. We aimed to assess the long-term efficacy of concurrent prosthetic IH repair with RARP. METHODS: Data for consecutive patients undergoing concurrent IH repair with RARP for localized prostate cancer at our institution between 2006 and 2017 were retrospectively analysed. Patients were matched based on age, BMI, and year of surgery, with patients undergoing RARP alone. IH repair was performed with a polyester mesh. Efficacy of IH repair was the primary outcome. Patient characteristics, perioperative data, recurrence and treatment were recorded. RESULTS: A total of 136 men were included, 50% treated by RARP and concurrent IH, 50% by RARP alone. Mean age was 65 years (SD 6) and mean BMI 26.8 (SD 2.5). IH was diagnosed preoperatively in 42 patients (62%) or intraoperatively in 26 patients (38%). A total 18 patients (26%) had bilateral hernias and 50 patients had unilateral hernias (right 31%, left 43%). There was no significant difference between the two groups regarding perioperative data. The herniorrhaphy added 34 min to the operative time (p < 0.001). After a mean follow-up of 106 months [SD 38], 9 patients (13%) presented recurrence of IH, with a mean time to recurrence of 43 months [SD 35]. Age was significantly associated with IH recurrence (p = 0.0007). CONCLUSION: Concomitant IH repair and RARP appear to be a safe procedure with good long-term safety and efficacy, without significantly increasing morbidity.

RESUMEN

BACKGROUND: Suitable selection criteria for focal therapy (FT) are crucial to achieve success in localized prostate cancer (PCa). OBJECTIVE: To develop a multivariable model that better delineates eligibility for FT and reduces undertreatment by predicting unfavorable disease at radical prostatectomy (RP). DESIGN, SETTING, AND PARTICIPANTS: Data were retrospectively collected from a prospective European multicenter cohort of 767 patients who underwent magnetic resonance imaging (MRI)-targeted and systematic biopsies followed by RP in eight referral centers between 2016 and 2021. The Imperial College of London eligibility criteria for FT were applied: (1) unifocal MRI lesion with Prostate Imaging-Reporting and Data System score of 3-5; (2) prostate-specific antigen (PSA) ≤20 ng/ml; (3) cT2-3a stage on MRI; and (4) International Society of Urological Pathology grade group (GG) 1 and ≥6 mm or GG 2-3. A total of 334 patients were included in the final analysis. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was unfavorable disease at RP, defined as GG ≥4, and/or lymph node invasion, and/or seminal vesicle invasion, and/or contralateral clinically significant PCa. Logistic regression was used to assess predictors of unfavorable disease. The performance of the models including clinical, MRI, and biopsy information was evaluated using the area under the receiver operating characteristic curve (AUC), calibration plots, and decision curve analysis. A coefficient-based nomogram was developed and internally validated. RESULTS AND LIMITATIONS: Overall, 43 patients (13%) had unfavorable disease on RP pathology. The model including PSA, clinical stage on digital rectal examination, and maximum lesion diameter on MRI had an AUC of 73% on internal validation and formed the basis of the nomogram. Addition of other MRI or biopsy information did not significantly improve the model performance. Using a cutoff of 25%, the proportion of patients eligible for FT was 89% at the cost of missing 30 patients (10%) with unfavorable disease. External validation is required before the nomogram can be used in clinical practice. CONCLUSIONS: We report the first nomogram that improves selection criteria for FT and limits the risk of undertreatment. PATIENT SUMMARY: We conducted a study to develop a better way of selecting patients for focal therapy for localized prostate cancer. A novel predictive tool was developed using the prostate-specific antigen (PSA) level measured before biopsy, tumor stage assessed via digital rectal examination, and lesion size on magnetic resonance imaging (MRI) scans. This tool improves the prediction of unfavorable disease and may reduce the risk of undertreatment of localized prostate cancer when using focal therapy.

RESUMEN

BACKGROUND: Findings from preclinical studies and one pilot clinical trial suggest potential benefits of epidural analgesia in acute pancreatitis. We aimed to assess the efficacy of thoracic epidural analgesia, in addition to usual care, in improving clinical outcomes of intensive care unit patients with acute pancreatitis. METHODS: A multicenter, open-label, randomized, controlled trial including adult patients with a clinical diagnosis of acute pancreatitis upon admission to the intensive care unit. Participants were randomly assigned (1:1) to a strategy combining thoracic epidural analgesia and usual care (intervention group) or a strategy of usual care alone (control group). The primary outcome was the number of ventilator-free days from randomization until day 30. RESULTS: Between June 2014 and January 2019, 148 patients were enrolled, and 135 patients were included in the intention-to-treat analysis, with 65 patients randomly assigned to the intervention group and 70 to the control group. The number of ventilator-free days did not differ significantly between the intervention and control groups (median [interquartile range], 30 days [15-30] and 30 days [18-30], respectively; median absolute difference of - 0.0 days, 95% CI - 3.3 to 3.3; p = 0.59). Epidural analgesia was significantly associated with longer duration of invasive ventilation (median [interquartile range], 14 days [5-28] versus 6 days [2-13], p = 0.02). CONCLUSIONS: In a population of intensive care unit adults with acute pancreatitis and low requirement for intubation, this first multicenter randomized trial did not show the hypothesized benefit of epidural analgesia in addition to usual care. Safety of epidural analgesia in this setting requires further investigation. TRIAL REGISTRATION: ClinicalTrials.gov registration number NCT02126332 , April 30, 2014.

RESUMEN

PURPOSE: To develop new selection criteria for active surveillance (AS) in intermediate-risk (IR) prostate cancer (PCa) patients. METHODS: Retrospective study including patients from 14 referral centers who underwent pre-biopsy mpMRI, image-guided biopsies and radical prostatectomy. The cohort included biopsy-naive IR PCa patients who met the following inclusion criteria: Gleason Grade Group (GGG) 1-2, PSA < 20 ng/mL, and cT1-cT2 tumors. We relied on a recursive machine learning partitioning algorithm developed to predict adverse pathological features (i.e., ≥ pT3a and/or pN + and/or GGG ≥ 3). RESULTS: A total of 594 patients with IR PCa were included, of whom 220 (37%) had adverse features. PI-RADS score (weight:0.726), PSA density (weight:0.158), and clinical T stage (weight:0.116) were selected as the most informative risk factors to classify patients according to their risk of adverse features, leading to the creation of five risk clusters. The adverse feature rates for cluster #1 (PI-RADS ≤ 3 and PSA density < 0.15), cluster #2 (PI-RADS 4 and PSA density < 0.15), cluster #3 (PI-RADS 1-4 and PSA density ≥ 0.15), cluster #4 (normal DRE and PI-RADS 5), and cluster #5 (abnormal DRE and PI-RADS 5) were 11.8, 27.9, 37.3, 42.7, and 65.1%, respectively. Compared with the current inclusion criteria, extending the AS criteria to clusters #1 + #2 or #1 + #2 + #3 would increase the number of eligible patients (+ 60 and + 253%, respectively) without increasing the risk of adverse pathological features. CONCLUSIONS: The newly developed model has the potential to expand the number of patients eligible for AS without compromising oncologic outcomes. Prospective validation is warranted.

RESUMEN

PURPOSE: We assess the efficacy, safety, and predictive factors for failure of synthetic mid-urethral slings for the treatment of urinary incontinence in a large cohort of women with neurogenic lower urinary tract dysfunction. MATERIALS AND METHODS: Women aged 18 years or older who received a synthetic mid-urethral sling for stress urinary incontinence or mixed urinary incontinence in 3 centers between 2004 and 2019 and who had a neurological disorder were included. Exclusion criteria were less than 1 year of follow-up, concomitant pelvic organ prolapse repair, previous synthetic sling implantation, and no baseline urodynamics. The primary outcome was surgical failure, defined as recurrence of stress urinary incontinence during follow-up. Kaplan-Meier analysis was used to estimate the 5-year failure rate. Adjusted Cox proportional hazard model was used to identify factors associated with surgical failure. Complications and reoperations during the follow-up have also been reported. RESULTS: A total of 115 women with a median age of 53 years were included. The median follow-up duration was 75 months. The 5-year failure rate was 48% (95 CI 46%-57%). Age above 50 years, negative tension-free vaginal tape test and transobturator route were associated with surgical failure. Thirty-six patients (31.3%) underwent at least 1 reoperation for complications or failure, and 2 required definitive intermittent catheterization. CONCLUSIONS: Synthetic mid-urethral slings may be an acceptable alternative to autologous slings or artificial urinary sphincters for the treatment of stress urinary incontinence in a selected group of patients with neurogenic lower urinary tract dysfunction.

RESUMEN

Background: Increasing use of multiparametric magnetic resonance imaging (mpMRI) has come with heterogeneity in image quality. The Prostate Imaging Quality (PI-QUAL) score is under scrutiny to assess its usefulness in predicting clinical outcomes. Objective: To compare upstaging of localized disease on mpMRI (mrT2) to locally invasive disease in radical prostatectomy (RP) specimens (≥pT3a) in relation to PI-QUAL. Design setting and participants: Patients treated with RP between 2015 and 2020 who underwent 1.5-3-T mpMRI within 6 mo before surgery and had systematic and mpMRI-US targeted biopsies were included. mpMRI scans were retrospectively assigned a PI-QUAL score, and prospectively acquired Prostate Imaging-Recording and Data System (PI-RADS) scores (version 2.0 or 2.1) were used. PI-QUAL scores were categorized as nondiagnostic (PI-QUAL <3), sufficient (PI-QUAL 3), or optimal (PI-QUAL >3). Outcome measurements and statistical analysis: We assessed the relationship between the PI-QUAL score and upstaging using multivariate logistic regression. mpMRI, clinical, and pathological findings were compared using χ2 tests and analysis of variance. Results and limitations: We identified 351 patients, of whom 40 (11.4%) had PI-QUAL <3, 57 (16.3%) had PI-QUAL 3, and 254 (72.3%) had PI-QUAL >3 scores. The distribution of PI-QUAL <3 (0-33.6%; p < 0.001) and PI-QUAL >3 (37.3-100%; p < 0.001) scores varied widely among centers. PI-QUAL ≥3 in comparison to PI-QUAL <3 was associated with a lower rate of upstaging (19% vs 35%; p = 0.02), greater detection of mrT3a and mrT3b prostate cancer (17.0% vs 2.5%; p = 0.016), a higher rate of PI-RADS 5 lesions (47% vs 27.5%; p = 0.002), a higher number of suspicious lesion (PI-RADS ≥3: 34.7% vs 15%; p = 0.012), and higher detection rates for aggregated (50.7% vs 22.5%; p = 0.001) and late (21.2% vs 0%; p < 0.001) extraprostatic extension. On multivariate analysis, PI-QUAL<3 was associated with more frequent upstaging in the RP specimen (odds ratio 3.4; p = 0.01). Conclusions: In comparison to PI-QUAL ≥3, PI-QUAL <3 was significantly associated with a higher rate of upstaging from organ-confined disease on mpMRI to locally advanced disease on pathology, lower detection rates for PI-RADS 5 lesions and extraprostatic extension, and a lower number of suspicious lesions. Patient summary: Poor image quality for magnetic resonance imaging (MRI) scans of the prostate is associated with underestimation of the stage of prostate cancer.

RESUMEN

BACKGROUND: Multiparametric magnetic resonance imaging (MRI) and MRI-targeted biopsy are nowadays recommended in the prostate cancer (PCa) diagnostic pathway. Ploussard and Mazzone have integrated these tools into novel risk classification systems predicting the risk of early biochemical recurrence (eBCR) in PCa patients who underwent radical prostatectomy (RP). We aimed to assess available risk classification systems and to define the best-performing. METHODS: Data on 1371 patients diagnosed by MRI-targeted biopsy and treated by RP between 2014 and 2022 at eight European tertiary referral centers were analyzed. Risk classifications systems included were the European Association of Urology (EAU) and National Comprehensive Cancer Network (NCCN) risk groups, the Cancer of the Prostate Risk Assessment (CAPRA) score, the International Staging Collaboration for Cancer of the Prostate (STAR-CAP) classification, the Ploussard and Mazzone models, and ISUP grade group. Kaplan-Meier analyses were used to compare eBCR among risk classification systems. Performance was assessed in terms of discrimination quantified using Harrell's c-index, calibration, and decision curve analysis (DCA). RESULTS: Overall, 152 (11%) patients had eBCR at a median follow-up of 31 months (interquartile range: 19-45). The 3-year eBCR-free survival rate was 91% (95% confidence interval [CI]: 89-93). For each risk classification system, a significant difference among survival probabilities was observed (log-rank test p < 0.05) except for NCCN classification (p = 0.06). The highest discrimination was obtained with the STAR-CAP classification (c-index 66%) compared to CAPRA score (63% vs. 66%, p = 0.2), ISUP grade group (62% vs. 66, p = 0.07), Ploussard (61% vs. 66%, p = 0.003) and Mazzone models (59% vs. 66%, p = 0.02), and EAU (57% vs. 66%, p < 0.001) and NCCN (57% vs. 66%, p < 0.001) risk groups. Risk classification systems demonstrated good calibration characteristics. At DCA, the CAPRA score showed the highest net benefit at a probability threshold of 9%-15%. CONCLUSIONS: The performance of risk classification systems using MRI and MRI-targeted information was less optimistic when tested in a contemporary set of patients. CAPRA score and STAR-CAP classification were the best-performing and should be preferred for treatment decision-making.

RESUMEN

Over the last year, urologic progress remains driven by evolutions in oncological and functionnal urology. Prostate cancer imaging modalities are improving, as well as treatment options for advanced stages. Kidney and bladder cancer are benefiting from new treatment modalities including immunotherapy, whose role in the peri-operative setting is still unclear. Surveillance startegies for testicular cancer has been greatly simplified, for the benefit of the patients. In functional urology, a new therapeutic class in now available for the treatment of overactive bladder. Mutliples alternatives to transurethral resection are emerging in the surgical treatment of benign prostatic hypertrophy, whose expected benefits will need to be validated by long-term studies.


Les progrès de cette année sont marqués par des avancées en uro-oncologie et urologie fonctionnelle. La prise en charge du cancer de la prostate s'améliore tant dans la qualité de son diagnostic que dans le traitement des stades avancés. Les cancers du rein et de la vessie bénéficient de nouvelles options de traitement incluant l'immunothérapie, qui cherche encore sa place en périopératoire. Quant au cancer des testicules, il a vu sa surveillance grandement simplifiée au bénéfice des patients. En urologie fonctionnelle, une nouvelle classe thérapeutique est désormais disponible pour le traitement de l'hyperactivité vésicale et de multiples alternatives à la résection endoscopique de la prostate émergent dans le traitement chirurgical de l'hypertrophie bénigne de la prostate. Il faudra toutefois valider les avantages espérés par des études à long terme.

RESUMEN

BACKGROUND: Predicting the risk of side-specific extracapsular extension (ECE) is essential for planning nerve-sparing radical prostatectomy (RP) in patients with prostate cancer (PCa). OBJECTIVE: To externally validate available models for prediction of ECE. DESIGN, SETTING, AND PARTICIPANTS: Sixteen models were assessed in a cohort of 737 consecutive PCa patients diagnosed via multiparametric magnetic resonance imaging (MRI)-targeted and systematic biopsies and treated with RP between January 2016 and November 2021 at eight referral centers. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Model performance was evaluated in terms of discrimination using area under the receiver operating characteristic curve (AUC), calibration plots, and decision curve analysis (DCA). RESULTS AND LIMITATIONS: Overall, ECE was identified in 308/1474 (21%) prostatic lobes. Prostatic lobes with ECE had higher side-specific clinical stage on digital rectal examination and MRI, number of positive biopsy cores, and International Society of Urological Pathology grade group in comparison to those without ECE (all p < 0.0001). Less optimistic performance was observed in comparison to previous published studies, although the models described by Pak, Patel, Martini, and Soeterik achieved the highest accuracy (AUC ranging from 0.73 to 0.77), adequate calibration for a probability threshold <40%, and the highest net benefit for a probability threshold >8% on DCA. Inclusion of MRI-targeted biopsy data and MRI information in models improved patient selection and clinical usefulness. Using model-derived cutoffs suggested by their authors, approximately 15% of positive surgical margins could have been avoided. Some available models were not included because of missing data, which constitutes a limitation of the study. CONCLUSIONS: We report an external validation of models predicting ECE and identified the four with the best performance. These models should be applied for preoperative planning and patient counseling. PATIENT SUMMARY: We validated several tools for predicting extension of prostate cancer outside the prostate gland. These tools can improve patient selection for surgery that spares nerves affecting recovery of sexual potency after removal of the prostate. They could potentially reduce the risk of finding cancer cells at the edge of specimens taken for pathology, a finding that suggests that not all of the cancer has been removed.

RESUMEN

PURPOSE: To assess the most efficient biopsy method to improve International Society of Urological Pathology (ISUP) grade group accuracy with final pathology of the radical prostatectomy (RP) specimen in the era of magnetic resonance imaging (MRI)-driven pathway. METHODS: A total of 753 patients diagnosed by transrectal MRI-targeted and systematic biopsies (namely "standard method"), treated by RP, between 2016 and 2021 were evaluated. Biopsy methods included MRI-targeted biopsy, side-specific systematic biopsies relative to index MRI lesion and combination of both. Number of MRI-targeted biopsy cores and positive cores needed per index MRI lesion were assessed. Multivariable analysis was performed to analyze predictive factors of upgrading using MRI targeted and ipsilateral systematic biopsies method. RESULTS: Overall, ISUP grade group accuracy varied among biopsy methods with upgrading rate of 35%, 49%, 27%, and 24% for MRI targeted, systematic, MRI targeted and ipsilateral systematic biopsies and standard methods, respectively (p < 0.001). A minimum of two positive MRI-targeted biopsies cores per index MRI lesion were required when testing MRI targeted and ipsilateral systematic biopsies method to reach equivalent accuracy compared to standard method. Omitting contralateral systematic biopsies spared an average of 5.9 cores per patient. At multivariable analysis, only the number of positive MRI-targeted biopsy cores per index MRI lesion was predictive of upgrading. CONCLUSION: MRI targeted and ipsilateral systematic biopsies allowed an accurate definition of ISUP grade group and appears to be an interesting alternative when compared with standard method, reducing total number of biopsy cores needed.

RESUMEN

Models predicting the risk of adverse pathology (ie, International Society of Urological Pathology [ISUP] grade group ≥3, pT3, and/or pN1) among patients operated by radical prostatectomy (RP) have been proposed to expand active surveillance (AS) inclusion criteria. We aimed to test these models in a set of 1062 low-risk and favorable intermediate-risk prostate cancer (PCa) patients diagnosed by multiparametric magnetic resonance imaging (MRI) and MRI-targeted biopsy. We hypothesized that the inclusion of radiological features into a novel model would improve patient selection. Performance was assessed using discrimination, calibration, and decision curve analysis (DCA). Available models were characterized by poor discrimination (areas under the receiver operating characteristic curve [AUCs] of 59% and 60%), underestimation of predicted risk on calibration plots, and a small amount of net benefit against a probability threshold of 40-50% at the DCA. The development of a novel model slightly improved discrimination (AUC of 63% vs 59%, p = 0.001, and 63% vs 60%, p = 0.07) and net benefit against threshold probabilities of ≥30%. This first multicenter study demonstrated the poor performance of models predicting adverse pathology and that implementation of MRI and MRI-targeted biopsy in this setting was not associated with a clear improvement in patient selection. Patients harboring low-risk or favorable intermediate-risk PCa and candidates for RP cannot be referred accurately to an AS program without a non-negligible risk of misclassification. PATIENT SUMMARY: We tested prediction models that could expand the selection of prostate cancer patients for active surveillance. Models were inaccurate and associated with a high risk of misclassification despite the implementation of multiparametric magnetic resonance imaging and targeted biopsies.

RESUMEN

Fraley's Syndrome is a rare anatomic vascular malformation described in 1966 where an aberrant crossing vessel compresses the upper infundibulum and leads to upper calyx massive dilation. It is mostly asymptomatic and the diagnosis often missed; however, surgery is usually required for symptomatic cases. Open surgery is still frequently used while minimally invasive management is anecdotal in the literature. We report the first robot-assisted calyceo-pyelostomy. An 18-year-old female patient presented with intermittent, recurring, severe left flank pain leading to insomnia, evolving in the last 3 months. A 3-phases computerized tomography scan (CT-scan) showed a rotated left kidney, with upper calyx massive dilation and thinning of the upper renal parenchyma without any evident obstacle. Cystocopy and retrograde pyelography were performed. It confirmed a single ureteral meatus, a single ureter, and a narrowed upper calyx with upper calyx dilation. An ureteral catheter (JJ stent) was inserted in the upper calyx and the patient was planned for surgical exploration. During robotic surgery, an abnormal crossing vessel was identified and the diagnosis of Fraley's syndrome was made intraoperatively. According to previous literature, a calyceo-pyelostomy with uncrossing of the upper major calyx and resection of the narrowed upper infundibulum was performed. Total operative time was 114 min, pneumoperitoneum time was 96 min, blood loss less than 10 ml, and patient was released on post-operative day 2. The ureteral stent was removed 4 weeks after the intervention. At 12 postoperative weeks, the patient had complete regression of pain and the 12 postoperative week CT-scan showed a reduction of the dilation and a patent anastomosis. Fraley's syndrome is a rare entity. In our case, the diagnosis of Fraley syndrome was made intraoperatively after an extensive previous workup, underlining the difficulty to make this diagnosis. We report and provide a video of the first robot-assisted procedure for Fraley's syndrome in a nephron-sparing technique. Patient was pain-free at the 3-month.

RESUMEN

Robot-assisted donor nephrectomy (RDN) is increasingly used due to its advantages such as its precision and reduced learning curve when compared to laparoscopic techniques. Concerns remain among surgeons regarding possible longer warm ischemia time. This study aimed to compare patients undergoing robotic living donor nephrectomy to the more frequently used hand-assisted laparoscopic nephrectomy (HLDN) technique, focusing on warm ischemia time, total operative time, learning curve, hospital length of stay, donor renal function and post-operative complications. Retrospective study comparing RDN to HLDN in a collaborative transplant network. 176 patients were included, 72 in RDN and 104 in HLDN. Left-sided nephrectomy was favored in RDN (82% vs 52%, p < 0.01). Operative time was longer in RDN (287 vs 160 min; p < 0.01), while warm ischemia time was similar (221 vs 213 secs, p = 0.446). The hospital stay was shorter in RDN (3.9 vs 5.7 days, p < 0.01).Concerning renal function, a slightpersistent increase of 7% of the creatinine ratio was observed in the RDN compared to the HLDN group (1.56 vs 1.44 at 1-month checkup, p < 0.01). The results show that RDN appears safe and efficient in comparison to the gold-standard HLDN technique. Warm ischemia time was similar for both techniques, whereas RDN operative time was longer. Patients undergoing RDN had a shorter hospital stay, this being possibly mitigated by differences in center release criteria. Donor renal function needs to be assessed on a longer-term basis for both techniques.
