Objectives To evaluate the risk of contracting severe COVID‐19, defined as COVID‐19 specific intensive care unit (ICU) admission or death, for patients undergoing urological surgery during the epidemic. To define consequences of receiving surgery for COVID‐19 patients. Patients and Methods This is a multicenter observational cohort study. Every patient receiving a urological procedure in Paris academic urological centers during the 4 initial weeks of surgical restrictions were included. Their status was updated minimum 3 weeks after the procedure. The main outcomes were the COVID‐19 specific ICU admission and death. Statistics were mostly descriptive. The Post‐operative COVID‐19 confirmed group was compared with non‐COVID patients using Chi‐square tests for categorical and Wilcoxon test tests for continuous variables. Results During the 4‐week period, 552 patients received surgery within 8 centers. At follow‐up, 57 (10%) patients were lost. Among the 11 preoperative COVID‐19 cases, one remained in ICU, no new admission, and no death. For the non‐COVID patients, 57 (12%) developed COVID‐related symptoms; only one case (0.2%) required COVID‐19 specific ICU and 3 (0.6%) patients died of COVID‐19 after surgery. Conclusions Performing urological surgery during the COVID‐19 epidemic peak has a limited impact on ICU admissions but presents a real (0.6%) risk of specific mortality. Surgical activities should be maintained according to this risk.

After most surgical management of benign prostatic hyperplasia (BPH), the resected tissue undergoes a histological examination. This examination is performed for the risk of finding an incidental prostate cancer (iPCa). The improvement of prostate cancer detection in the past few years decreased the global iPCa rate. This raises the question of the real benefit for all patients of a systematic histological analysis. The aim of our study was to evaluate the iPCa detection rate on a large contemporary cohort of patients treated for BPH, and to define predictive factors of iPCa detection.We retrospectively analyzed the medical charts of all consecutive patients who underwent surgical treatment for BPH in our academic center from 2012 to 2018. Patients with prostate cancer diagnosed before surgery were not included. All the resected tissue underwent standard histopathological examination. iPCa was defined by any grade or stage of prostate cancer identified on the resected tissue by the histological examination. The following variables were analyzed using an uni- and multi-variable logistic regression as potential risk factors of iPCa: age, total PSA, PSA density (PSAd), prostate volume, technique used, weight of resected tissue and use of 5ARI medication.1045 patients were included in the study. Of them, 439 (42.0%), 206 (19.7%) and 400 (38.3%) underwent HoLEP, OP and TURP, respectively. iPCa was diagnosed in 94 (9.0%) of the 1045. Among them 15 (1.4%) were clinically significant (ISUP score ≥ 2). The multivariable logistic regression analysis identified age (p = 0.03) and PSA density (p 0.001) as independent predictive factors for the detection of iPCa. Using the median of age and PSAd, we identified a population with 0% of iPCa in our cohort (age 70 year-old and PSAd 0.05 ng/mL/mL).The global iPCa rate was 9% in this contemporary large cohort of patients who underwent surgical treatment for BPH, with 1.4% of clinically significant cancer. Age and PSAd were independent predictive factors to find iPCa. Patients younger than 70 with a PSAd 0.05 ng/mL/mL had 0% of iPCA in our cohort. In this specific population, we could probably avoid a systematical histological examination of the resected tissue.

Resume Introduction Le diagnostic des tumeurs urotheliales de la vessie repose sur la resection trans-uretrale des lesions, et leur analyse histologique. Le temps necessaire a l’obtention des resultats de l’analyse histologique augmente les delais de prise en charge. Par ailleurs, l’absence de muscle sur les prelevements necessite une nouvelle procedure de resection. La FFOCT est une technique d’imagerie rapide du tissu frais. L’objectif principal de notre etude etait d’evaluer la faisabilite et la performance diagnostique de la FFOCT pour determiner la presence de musculeuse et de foyers tumoraux sur les copeaux de resection trans-uretrale de vessie (RTUV). Patients et methodes Nous avons analyse en FFOCT les copeaux de resections de 24 patients consecutifs. Trois lecteurs ont analyse les images en aveugle, en recherchant la presence de muscle et de tumeur sur chaque copeau. Les resultats ont ete compares a l’analyse histologique pour calculer les performances diagnostiques de chaque lecteur. Resultats Les sensibilite moyennes pour la detection du muscle et la detection de tumeurs etaient respectivement de 75 % et 81 %. Les specificites moyennes pour la detection de muscle et la detection de tumeur etaient respectivement de 78,3 % et 55,3 %. Conclusion Nos resultats suggerent que la FFOCT des copeaux de resection de tumeur urotheliale est faisable. Les sensibilites et specificites calculees sont encourageantes pour la detection de muscle et la detection de la tumeur. La performance de cet outil de detection et stadification precoce devra etre confirmee sur un plus grand nombre de patients. Niveau de preuve 3.

Summary Introduction Greenhouse gas (GHG) emissions are a serious environmental issue. The healthcare sector is an important emitter of GHGs. Our aim was to assess the environmental cost of teleconsultations in urology compared to face-to-face consultations. Materials and methods Prospective study of all patients who had a remote teleconsultation over a 2-week period during COVID-19 pandemic. Main outcome was the reduction in CO2e emissions related to teleconsultation compared to face-to-face consultation and was calculated as: total teleconsultation CO2e emissions–total face-to-face consultation CO2e emissions. Secondary outcome measures were the reduction in travel distance and travel time related to teleconsultation. Results Eighty patients were included. Face-to-face consultations would have resulted in 6699 km (4162 miles) of travel (83.7 km (52 miles) per patient). Cars were the usual means of transport. CO2e avoided due to lack of travel was calculated at 1.1 tonnes. Teleconsultation was responsible for 1.1 kg CO2e while face-to-face consultation emitted 0.5 kg of CO2e. Overall, the total reduction in GHGs with teleconsultation was 1141 kg CO2e, representing a 99% decrease in emissions. Total savings on transport were 974 € and savings on travel time were 112 h (1.4 h/patient). Conclusions Teleconsultation reduces the environmental impact of face-to-face consultations. The use of teleconsultation in our urology departments resulted in the avoidance of more than 6000 km of travel, equivalent to a reduction of 1.1 tonnes of CO2e. Teleconsultation should be considered for specific indications as the healthcare system attempts to become greener. Level of evidence 3.

The COVID-19 pandemic led to a decrease in surgical activity to avoid nosocomial contamination. Robotic-assisted surgery safety is uncertain, since viral dissemination could be facilitated by gas environment. We assessed the impact and safety of the COVID-19 pandemic on robotic-assisted surgery. Data were collected prospectively during lockdown (March 16th–April 30th 2020) in 10 academic centres with robotic surgical activity and was compared to a reference period of similar length. After surgery, patients with suspected COVID-19 were tested by RT-PCR. During the COVID-19 lockdown we evidenced a 60% decrease in activity and a 49% decrease in oncological procedures. However, the overall proportion of oncological surgeries was significantly higher during the pandemic (p

Objective To assess the feasibility, safety and precision of organ-based tracking (OBT)-fusion targeted focal microwave ablation (FMA), in patients with low to intermediate risk prostate cancer. Patients and method Ten patients with a visible index tumor of Gleason score ≤3+4, largest diameter Results Median [IQR] age was 64.5 [61–72] years and baseline PSA was 5 [4.3–8.1] ng/mL. Seven (70%) and 3 (30%) patients had a low and intermediate risk cancer, respectively. Median largest tumor axis was of 11 [9.0–15.0] mm. Median duration of procedure was of 82 [44–170] min. No patient reported any pain or rectal bleeding, and all 10 patients were discharged the next day. Seven days after ablation, total necrosis of the index tumor on MRI was obtained in eight (80% [95%CI 55%-100%]) patients. One patient was treated with radical prostatectomy. Re-biopsy at 6 months in the other 9 did not show evidence of cancer in 4 patients. IPSS, IIEF-5 and MSHQ-EjD-SF were not statistically different between baseline and 6 months follow up. Conclusions OBT-fusion targeted FMA was feasible, precise, and safe in patients with low to intermediate risk localized prostate cancer.

International audience; Purpose: Lockdown during the COVID-19 pandemic compelled urologists to change access to healthcare, especially for oncology patients. Teleconsultation is a safe way to receive medical advice without a risk of infection, and was implemented urgently in our academic centres. Our purpose was to evaluate patient and physician satisfaction with teleconsultation set up during the COVID-19 pandemic.Methods: From March 16th 2020, all face-to-face consultations were cancelled in France, except for emergencies. Teleconsultation was started immediately by five senior urologists in two academic hospitals. All patients received an email survey including the validated Teleconsultation Satisfaction Questionnaire (TSQ) and demographic questions. Data were collected prospectively. Physicians also responded to the TSQ. Patient satisfaction was measured objectively with the validated 14-item TSQ. Each item was scored on a 5-point Likert scale. Factors associated with positive satisfaction with teleconsultation were assessed by multivariable logistic regression.Results: Overall, 105 patients replied to the survey (91.3%). Median age was 66 years (IQR: 55‒71) and 95 were men (90.5%). Median overall TSQ score was 67 (IQR: 60‒69); teleconsultation was judged to be a good experience by 88 patients (83.8%) and four physicians (80%). Patients who met their surgeon for the first time were more likely to have a good experience (OR = 1.2 [95% CI 1.1‒1.5], p = 0.03).Conclusion: Introduced rapidly during the COVID-19 lockdown, urology teleconsultation attained a high level of satisfaction among both patients and physicians. A major change in telemedicine use is foreseen in the post COVID-19 era.

International audience; Introduction: As a result of the COVID-19 pandemic in France, all non-emergency surgical activity has been cancelled since March 12, 2020. In order to anticipate the reinstatement of delayed interventions, surgical activity reduction analysis is essential. The objective of this study was to evaluate the reduction of urological surgery in adult during the COVID-19 pandemic compared to 2019.Material: The data regarding urological procedures realized in the 8 academic urological departments of Parisians centres (AP-HP) were compared over two similar periods (14-29 March 2019 and 12-27 March 2020) using the centralized surgical planning software shared by these centres. Procedure title, type of surgery and outpatient ratio were collected. The interventions were sorted into 16 major families of urological interventions.Results: Overall, a 55% decrease was observed concerning urological procedures over the same period between 2019 and 2020 (995 and 444 procedures respectively). Oncology activity and emergencies decreased by 31% and 44%. The number of kidney transplantations decreased from 39 to 3 (-92%). Functional, andrological and genital surgical procedures were the most impacted among the non-oncological procedures (-85%, -81% and -71%, respectively). Approximatively, 1033 hours of surgery have been delayed during this 16-day period.Conclusion: Lockdown and postponement of non-urgent scheduled urological procedures decisions has led to a drastic decrease in surgical activity in AP-HP. Isolated kidney transplantation has been stopped (national statement). Urologists must anticipate for lockdown exit in order to catch-up delayed surgeries.Level of evidence: 3.; IntroductionEn conséquence de la pandémie de COVID-19 en France, toute activité chirurgicale non urgente a dû être annulée à partir du 12 mars 2020. Afin d’anticiper la reprise des interventions décalées, une quantification de la réduction d’activité est nécessaire. L’objectif de l’étude était d’évaluer comparativement à 2019 la réduction d’activité chirurgicale urologique adulte pendant la pandémie de COVID-19.Matériel et méthodesNous avons comparé le nombre d’interventions urologiques pratiquées dans les 8 services universitaires d’urologie de l’Assistance Publique – Hôpitaux de Paris (AP–HP) sur deux périodes comparables (14–29 mars 2019 et 12–27 mars 2020) à l’aide du logiciel de planification opératoire et du PMSI partagé par ces centres. L’intitulé d’intervention et le type de chirurgie ont été collectés et regroupées en 16 catégories.RésultatsUne baisse de l’activité globale à l’AP–HP en urologie de 55 % entre 2019 et 2020 (995 et 444 interventions respectivement) a été constatée sur les 8 services. L’activité oncologique et les urgences ont diminué de 31 % et 44 %. L’activité de transplantation rénale, la chirurgie fonctionnelle et andrologique ont subi les plus fortes baisses d’activité par les interventions non oncologiques (−92 %, −85 % et −81 %, respectivement). Environ 1033 heures d’intervention devront être reprogrammées pour rattraper le programme opératoire annulé.ConclusionLe confinement et le report des interventions chirurgicales « non urgentes » ont entraîné une diminution drastique de l’activité chirurgicale au sein de l’AP–HP. Pendant cette période, les urologues ont été sollicités pour d’autres tâches mais doivent désormais s’atteler à organiser la période de reprise d’activité pour éviter une crise organisationnelle en urologique.Niveau de preuve3.

Resume Introduction La pose d’implants intra-prostatiques Urolift est une technique mini-invasive, qui se place comme alternative aux techniques chirurgicales classique de l’hyperplasie benigne de la prostate. Notre objectif etait de rapporter les resultats de la pose d’implants Urolift® apres 7 ans d’experience. Patients et methode L’intervention a ete proposee entre fevrier 2012 et mars 2019 aux patients consultant dans notre centre pour hyperplasie benigne de la prostate (HBP) symptomatique, en alternative a un traitement chirurgical classique. L’efficacite etait evaluee par auto-questionnaire sur la symptomatologie urinaire (IPSS) et sur son retentissement (IPSS-QdV). La tolerance etait evaluee par questionnaires sur la fonction erectile (IIEF5) et ejaculatoire (MSHQ-EjD) et le taux de complications. La survie sans traitement additionnel a ete evaluee. Resultats Quarante patients ont ete traites pendant cette periode, avec un suivi moyen de 32 mois [12—67]. Trois mois apres l’intervention, l’IPSS et l’IPSS-QdV etaient significativement ameliores (respectivement 8 [4–11] vs 20 [17–24] ; p 2 n’a ete rapportee. La survie sans traitement additionnel a 5 ans etait de 50 %. Conclusions La pose d’implants intra-prostatiques Urolift® a permis une amelioration significative des symptomes dans notre population, avec une bonne tolerance. Environ deux tiers des patients n’avaient pas recu de traitement additionnel en fin d’experience. Le risque de reintervention etait maximal au cours des dix-huit premiers mois. Niveau de preuve 3.

Objective To prospectively study the impact of smoking on pathological response to neoadjuvant chemotherapy (NAC) in patients undergoing radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB). Materials & methods We collected standard clinicopathological variables, including smoking status (never, former, current) in patients undergoing NAC and RC for UCB at 12 European tertiary care centers between 12/2013-12/2015. Clinicopathological variables were compared according to smoking status. Multivariable logistic regression models were built to assess the association of smoking status and a) complete (no residual disease), b) partial (residual, non-muscle invasive disease), c) no pathological response (residual muscle invasive or lymph node positive disease). Kaplan-Meier and Cox regression analyses were employed to study the impact of response to NAC on survival. Results and limitations Our final cohort consisted of 167 NAC patients with a median follow-up of 15 months (interquartile range (IQR) 9–26 months) of whom 48 (29%), 69 (41%), and 50 (30%) where never, former, and current smokers, respectively. Smoking was significantly associated with advanced age (p = 0.013), worse ECOG performance status (p = 0.049), and decreased pathological response to NAC (p = 0.045). On multivariable logistic regression analyses, former and current smoking status was significantly associated with lower odds of complete pathological response (odds ratio (OR) 0.37, 95% confidence interval (CI) 0.16–0.87, p = 0.023, and OR 0.34, 95% CI 0.13–0.85, p = 0.021), while current smoking status was significantly associated with a greater likelihood of no pathological response (OR 2.49, 95% CI 1.02–6.06, p = 0.045). Response to NAC was confirmed as powerful predictor of survival. Conclusions Smoking status is adversely associated with pathological response to NAC. Smokers should be informed about these adverse effects, counseled regarding smoking cessation, and possibly be considered for immunotherpeutics as they may be more effective in smokers.

Objectifs Le score PIRADS a ete developpe afin de standardiser l’interpretation des IRM prostatiques, et une probabilite croissante de detecter un cancer lors des biopsies mise en evidence avec l’augmentation du score PIRADS, plus de 80 % des lesions PIRADS 5 correspondant a un cancer significatif. Nous avons cherche a evaluer le role pronostique potentiel de ce score PIRADS 5 chez des patients traites par prostatectomie totale. Methodes A partir d’une base de donnees multicentrique europeenne, nous avons analyse les donnees de 539 patients porteurs d’une lesion classee PIRADS V2 = 5 sur l’IRM pre-biopsie, ayant eu des biopsies ciblees et systematiques, puis operes d’une prostatectomie totale. Les donnees de suivi etaient disponibles pour 448 patients. La survie sans recidive biochimique (SSRB) etait analysee selon la methode de Kaplan–Meier. Un modele de Cox uni- puis multivarie a permis l’analyse des facteurs preoperatoires associes a la recidive biochimique. Resultats L’âge median etait de 66 ans (IQR : 61–70), le PSA a 8 ng/mL (6–12), la densite de PSA a 0,2 (0,14–0,3). L’IRM suggerait une extension extra-prostatique (EEC) dans 32 %. Le diametre median des lesions etait de 16 mm (14–20). Le grade ISUP biopsique etait ≥ 3 dans 44 %. Le suivi median etait de 25 mois (12–39). Une EEC etait confirmee par l’anatomopathologie definitive dans 55 %, les marges d’exerese etaient positives dans 35 %. Un envahissement ganglionnaire etait detecte dans 19 %. La SSRB mediane etait de 28 % a 5 ans (IC95 : 18–39) ( Fig. 1 ). Parmi les facteurs etudies, le stade T IRM ( Fig. 2 ), la densite de PSA (HR : 6,35, IC95 : 2,4–16,9) et le % de biopsies ciblees positives (HR : 1,13, IC95 : 1,06–1,2) etaient significativement associes au risque de recidive biochimique en analyse multivariee. Conclusion Les patients ayant a l’IRM prostatique pre-biopsie une lesion classee PIRADS 5 sont a haut risque de recidive biochimique precoce apres prostatectomie totale. Le stade T IRM, la densite de PSA et le % de biopsies ciblees positives peuvent aider a ameliorer la selection et l’information des candidats a une prise en charge chirurgicale.

Calcium stones and calculi are observed in numerous human tissues. They are the result of deposition of calcium salts and are due to high local calcium concentrations. Prostatic calculi are usually classified as endogenous or extrinsic stones. Endogenous stones are commonly caused by obstruction of the prostatic ducts around an enlarged prostate resulting from benign prostatic hyperplasia or from chronic inflammation. The latter occurs mainly around the urethra and is generally caused by reflux of urine into the prostate. Calcium concentrations higher than in the plasma at sites of infection may induce the chemotactic response that eventually leads to recruitment of inflammatory cells. The calcium sensing receptor (CaSR) may be crucial for this recruitment as its expression and activity are increased by cytokines such as IL-6 and high extracellular calcium concentrations, respectively. The links between calcium calculi, inflammation, calcium supplementation, and CaSR functions in prostate cancer patients will be discussed in this review.

Urolift® system is a mini-invasive technique, proposed as an alternative treatment for classic surgery of benign prostatic hyperplasia (BPH). Our objective was to report the results of Urolift® system in our center after 7years experience.Urolift® implants were proposed between February 2012 and March 2019 for patients presenting symptomatic BPH in our center, as an alternative for classic surgery. The efficacy was evaluated with questionnaires about lower urinary tract symptoms (IPSS) and its impact on quality of life (IPSS-QdV). Tolerance was evaluated with questionnaires about erectile (IIEF5) and ejaculatory function (MSHQ-EjD) and complication rate. Survival without additional treatment was assessed using Kaplan-Meier method.Forty patients were treated during this period, with a median follow-up of 32months [12-67]. Three months after the procedure, IPSS and IPSS-QdV were significantly improved (respectively 8 [4-11] vs 20 [17-24]; P0.0001 and 2 [1-2] vs 5 [4-6]; P0.0001). MSHQ-EjD and IIEF5 were not modified (respectively 13 [11-14] vs 12 [9-13]; P=0.69 and 21 [18-23] vs 21 [18-23]; P=0.13). Two patients (5%) experienced a urinary retention and needed a bladder catheter. No complication with a Clavien-Dindo score2 were reported. Survival without additional treatment at 5years was 63%.Urolift® implants improved significantly the lower urinary tract symptoms in our population, with a good tolerance profile. More than 60% of the patients did not need an additional treatment after 5years of follow-up.3.

The diagnosis of bladder urothelial tumors is based on bladder resection and histological analysis of the specimen. The time to obtain the results of the histological analysis increases the treatment delay. Furthermore, the lack of muscle on the specimen forces the surgeon to practice on other procedure. Full field optical coherence tomography (FFOCT) is a recent imaging technique to analyze tissue. The aim of our study was to evaluate the feasibility and diagnostic accuracy of FFOCT to detect muscle and tumor in bladder resection specimen.We analyzed with the FFOCT technique bladder resection specimen of 24 consecutives patients. Three readers did the blind analyze of the images, looking for the presence of muscle and tumor on each specimen. Their results were compared with histological analysis to calculate diagnostic accuracy for each reader.Mean sensibilities for the detection of muscle and tumor were respectively 75% and 81%. Mean specificities for the detection of muscle and tumor were respectively 78.3% and 55.3%.Our results suggest that the FFOCT is feasible to analyze bladder resection specimen. Sensibilities and specificities calculated are encouraging for the detection of muscle and tumor. The accuracy of this detection and early-staging tool should be validated by larger studies.3.

Body mass index (BMI) has been associated with worse outcomes in several solid malignancies. We aimed to evaluate the association between BMI and oncological outcomes in patients treated with radical cystectomy (RC) for muscle-invasive urothelial carcinoma of the bladder (UCB). We retrospectively reviewed 701 consecutive patients treated with RC and pelvic lymphadenectomy for UCB at our institution between 1995 and 2011. Univariable and multivariable Cox regression models investigated the association of BMI with disease recurrence and cancer-specific mortality. BMI was analyzed as both continuous and categorical variable (

Objectifs Le confinement lie au COVID-19 a force les urologues a proposer de nouvelles offres d’acces aux soins pour leurs patients, notamment en oncologie. La teleconsultation, en limitant le risque d’exposition au virus, est une alternative sure pour les patients mise en place en urgence dans nos centres. Notre objectif etait d’evaluer la satisfaction des patients et des medecins concernant la teleconsultation pendant la pandemie COVID-19. Methodes A partir du 16 mars 2020, toutes les consultations en presentiel ont ete annulees en France, a l’exception des urgences. Nous avons evalue la teleconsultation initiee immediatement par 5 urologues seniors dans 2 centres universitaires. Tous les patients ayant consulte ont recu par mail le questionnaire valide evaluant la satisfaction suite a une teleconsultation (TSQ). Ces items ont egalement ete remplis par les consultants. Le TSQ comprenait 14 items etant chacun cote par une echelle de Likert a 5 points. Les facteurs associes a une bonne satisfaction etaient recherches par regression logistique multivariee. Resultats Au total, 105 patients ont repondu au questionnaire (91,3 %). L’âge median etait de 66 ans (IQR = 55–71), et 95 etaient des hommes (90,5 %). La majorite des consultations correspondaient a un suivi medical (n = 72,68 %) oncologique (n = 46, 44 %). Vingt-quatre patients (23 %) rencontraient leur urologue pour la premiere fois ( Fig. 1 ). Le TSQ median etait de 67 (IQR = 60–69) ; la teleconsultation etait jugee comme une bonne experience par 88 patients (83,8 %) et par 4 urologues (80 %). Les patients qui rencontraient leur chirurgien pour la premiere fois au cours de la teleconsultation etait plus a meme de considerer l’experience comme bonne (OR = 1,2, IC95 % = 1,1–1,5, p = 0,03). Conclusion Debutee en urgence durant la pandemie de COVID-19, la teleconsultation en urologie est une alternative ayant atteint un haut niveau de satisfaction a la fois pour les patients et les praticiens, indiquant potentiellement un changement majeur dans l’utilisation de cette technologie apres la crise sanitaire.

Objectifs La tomographie par coherence optique (OCT) plein champ est une technique d’imagerie du tissu frais ex vivo. Notre objectif etait d’en evaluer les performances diagnostiques sur biopsies prostatiques pour la detection du cancer de la prostate. Methodes Cette etude diagnostique a ete proposee de janvier 2016 a janvier 2017 aux patients ayant une premiere serie de biopsies prostatiques dans notre centre. Une image OCT plein champ etait acquise pour chaque carotte. Toutes les carottes etaient analysees de maniere independante. Deux urologues et deux internes d’urologie ont analyse les images OCT plein champ en aveugle, pour determiner la presence de cancer. Un programme d’intelligence artificielle (IA) a ete entraine de maniere non supervisee sur les 506 premieres images, puis teste sur les 490 images restantes. La sensibilite (Se), specificite (Sp) et valeur predictives ont ete calculees pour chaque lecteur et pour l’IA. Resultats Quatre-vingt-huit patients ont ete inclus, et 996 carottes analysees. Pour la detection de cancer, les lecteurs obtenaient 0,37 Fig. 1 ). Conclusion Nos resultats suggerent que l’OCT plein champ a une VPN elevee pour eliminer la presence de cancer en temps reel sur carotte biopsique. Cette VPN augmente pour les cancers significatifs. Notre programme d’IA necessite un apprentissage sur un plus grand nombre d’image.

Summary Introduction Prostatic arterial embolization (PAE) is an experimental therapy for benign prostatic hyperplasia. Its feasibility is based on the knowledge of the pelvic arterial anatomy, and more specifically the prostate. The aim of this study was to describe the prostatic arterial supply: origins, distribution and variability. Material and methods We reviewed retrospectively, with two radiologists, 40 arteriographies of patients who underwent PAE in our center. With these observations of 80 hemipelvics, we described the number of prostatic arteries, their origins, their distributions and eventually their anastomoses with other pelvic arteries. Results There was one prostatic artery in 70% of the cases. It came from a common trunk for the prostate and the bladder in 55% of the cases, from the obturator artery in 17.5% of the cases, from the pudendal artery in 25% of the cases, from the intern iliac artery in 1% of the cases, and from the superior gluteal artery in 1% of the cases. The prostatic artery splitted in two branches (medial and lateral), with no anastomoses in 37% of the cases. Anastomoses with penile and rectal arteries were observed in 29% of the cases. Conclusions For our 40 patients, we observed many variations of arterial prostatic anatomy. We proposed a classification in order to increase security and efficacy of PAE, and it should be validated with more patients. Level of evidence 2.

Objectives: The purpose of this study was to investigate the impact of neoadjuvant chemotherapy (NAC) on perioperative morbidity and on oncological outcomes according to the type of chemotherapy regimen administered to patients with muscle-invasive bladder cancer (MIBC) who subsequently underwent radical cystectomy (RC). Methods: Data were collected retrospectively on 40 patients with bladder urothelial carcinoma who had at least two cycles of NAC, followed by RC, from 2011 to 2015 at our institution. The outcomes evaluated were NAC toxicity, perioperative complications, cancer-specific, and overall survival. Results: Among these cases, 23 patients (57.5%) received methotrexate, vinblastine, doxorubicin and cisplatin (MVAC), 4 patients (10%) received gemcitabine and cisplatin (GC), and 13 patients (32.5%) received other regimes. The early and late postoperative complication rates were 35% and 12.5%. Regarding toxicity, 85% of patients had at least one side effect of NAC, but only 21.7% discontinued therapy in the MVAC group. The pathological complete response (pCR) rates for cisplatin-based regimens (MVAC and GC) and other regimens were 44.4 and 15.4%, respectively, (p = 0.09). The pathological partial response (pPR) rates for cisplatin-based regimens and other regimens were 66.7 and 15.4%, respectively, (p = 0.002). Patients treated with a cisplatin-based chemotherapy regimen had longer overall survival than those treated with other regimen (median 38.1 vs. 18.4 months, p = 0.01). Conclusions: NAC administration was not associated with high toxicity or surgical morbidity. The pathological response rates and survival outcomes in the cisplatin-based regimens were higher than with those with non-cisplatin-based regimens. These data support the use, in patients elective to a neoadjuvant setting prior to RC for MBIC, of a cisplatin-based regimen.

Transurethral resections are commonly used for bladder cancer diagnosis, treatment and follow-up. Cancer staging relies largely on the analysis of muscle in the resections; however, muscle presence is uncertain at the time of the resection. An extemporaneous quality control tool would be of great use to certify the presence of muscle in the resection, and potentially formulate a primo-diagnosis, in order to ensure optimum patient care. Full-field optical coherence tomography (FFOCT) offers a fast and non-destructive method of obtaining images of biological tissues at ultrahigh resolution (1μm in all 3 directions), approaching traditional histological sections. This study aimed to evaluate the potential of FFOCT for the quality control and the primo-diagnosis of transurethral bladder resections. Over 70 transurethral bladder resections were imaged with FFOCT within minutes, shortly after excision, and before histological preparation. Side-by-side comparison with histology allowed to establish reading criteria for the presence of muscle and cancer in particular. Images of 24 specimens were read blindly by three non-pathologists readers: two resident urologists and a junior bio-medical engineer, who were asked to notify the presence of muscle and tumor. Results showed that after appropriate training, 96% accuracy could be obtained on both tumour and muscle detection. FFOCT is a fast and nondestructive imaging technique that provides analysis results concordant with histology. Its implementation as a quality control and primo-diagnosis tool for transurethral bladder resections in the urology suite is feasible and lets envision high value for the patient.

Objectifs Plusieurs etudes retrospectives ont suggere l’existence de mecanismes de resistance aux sels de platine induits par la nicotine. Aucune association entre l’intoxication tabagique et la reponse a la chimiotherapie neoadjuvante n’a ete demontree chez les patients traites pour carcinome urothelial de vessie. L’objectif de cette etude etait d’evaluer cette association sur une cohorte multicentrique contemporaine. Methodes Nous avons collecte prospectivement les donnees cliniques et anatomopathologiques incluant le statut tabagique (non fumeur, sevre, actif) et l’exposition (nombre de cigarettes par jour, duree d’exposition, duree du sevrage) chez les patients traites par chimiotherapie neoadjuvante, puis cystectomie totale pour carcinome urothelial de vessie dans 11 centres entre 2013 et 2016. Une analyse de regression logistique et une regression de cox ont ete conduites afin d’evaluer l’association du statut tabagique (statut et exposition) avec (a) une reponse complete (pas de maladie residuelle) ; (b) partielle (maladie residuelle non infiltrante) ; (c) l’absence de reponse (maladie residuelle infiltrante ou n + ) et (d) les survies sans recidive, specifique et globale. Resultats Sur les 168 patients analyses, 47 (28 %), 71 (42,3 %) et 50 (29,8 %) etaient respectivement non fumeurs, sevres et actifs. Le tabagisme etait associe a la presence de cis sur la piece de cystectomie totale (p = 0,02) et le tabagisme actif etait significativement associe a une duree d’exposition plus longue (30 vs. 36 ans , p Conclusion Dans cette etude, le tabagisme actif et sevre etait associe a une moindre reponse a la chimiotherapie neoadjuvante avant cystectomie totale. Une augmentation de la duree de suivi permettra d’evaluer l’impact de ces resultats sur la survie. En attendant des validations de ces donnees, les patients devraient etre informes du risque et beneficier d’une aide au sevrage.

Objectifs Le pronostic du cancer de prostate varie en fonction des caracteristiques tumorales. La presence d’un contingent neuro-endocrine est associee a un pronostic pejoratif. Nous avons montre que le calcium peut accelerer la progression tumorale et que ses effets passent par un recepteur au calcium (CaSR), associe a un mauvais pronostic. Notre objectif a alors ete de montrer l’implication du CaSR dans la differenciation neuro-endocrine. Methodes Nous avons analyse retrospectivement les liquides de rincage du pistolet a biopsies, des patients ayant beneficie de biopsies prostatiques ciblees dans notre centre entre janvier 2013 et novembre 2016. Des qPCR ont ete realisees pour rechercher l’expression du CaSR et de la synaptophysine, un des marqueurs les mieux etablis pour les cellules neuro-endocrines. Une analyse de regression logistique multivariee a ete realisee pour rechercher les facteurs associes a l’expression de CaSR et synaptophysine. En parallele nous avons analyse par qPCR l’expression de CaSR et synaptophysine sur la lignee cellulaire tumorale prostatique humaine (LNCaP) chez lesquelles nous avons induit la differenciation neuro-endocrine. Resultats Nous avons analyse les liquides de rincage de 214 patients et 164 qPCR ont pu etre realisees sur ce materiel. Sur les 164 liquides de rincages, 100 (61,3 %) correspondaient a une biopsie positive. Le CaSR etait exprime chez 52 (32 %) patients. La synaptophysine etait exprimee chez 116 (71 %) patients. Quatre-vingt-trois pour cent des patients qui exprimaient le CaSR exprimaient la synaptophysine. Chez les patients exprimant CaSR et synaptophysine, la prevalence du cancer etait de 70 %. Chez les patients n’exprimant aucun des deux marqueurs, la prevalence du cancer etait de 44,7 % (p = 0,0232). En analyse multivariee, l’expression de CaSR et synaptophysine n’etaient pas associees a la presence de cancer, ni aux caracteristiques tumorales. La differenciation neuro-endocrine des LNCaP a montre l’apparition et la co-localisation du CaSR et de la synaptophysine au niveau cellulaire. Conclusion Le CaSR a ete associe a une surmortalite dans un travail recent, mais n’est pas associe aux caracteristiques tumorales au moment du diagnostic. Le CaSR pourrait donc jouer un role tardif dans l’evolution du cancer en favorisant l’apparition d’un contingent neuro-endocrine. Le suivi de notre cohorte pourrait permettre de valider cette hypothese.

Objectifs Les kystes renaux Bosniak III–IV relevent d’une nephrectomie partielle en raison du risque de malignite rapporte : 30–60 % pour les Bosniak III et pres de 90 % pour les Bosniak IV. La rupture kystique peroperatoire est a risque theorique de dissemination tumorale (« spillage ») sans impact demontre sur la survie sans recidive. L’objectif de l’etude etait d’analyser la cellularite du liquide intrakystique. Methodes Tous les patients operes d’une tumeur kystique dans notre centre entre novembre 2017 et avril 2018 ont ete inclus. Les donnees cliniques et radiologiques etaient colligees de maniere prospective avec classification selon Bosniak des kystes. Apres exerese operatoire, le liquide intrakystique etait ponctionne au bloc operatoire, puis envoye en frais en anatomopathologie. Apres obtention d’un culot cellulaire par centrifugation, un examen cytologique direct recherchait la presence de cellules tumorales. Le culot etait fixe pour analyse immunohistochimique (recherche des marqueurs pax-8 et ca-ix) et congele pour analyse ulterieure de l’ADN tumoral. Resultats Vingt patients ont ete inclus au total, dont 62 % de kystes Bosniak IV et 22 % de Bosniak III. Seize pour cent des kystes etaient non classables ou survenaient chez des patients avec maladie de von Hippel-Lindau. Deux patients ont ete operes par nephrectomie elargie, tous les autres par nephrectomie partielle. Environ 30 % des patients etaient operes par laparoscopie robot-assistee. L’analyse histologique finale retrouvait 14 carcinomes renaux a cellules claires, dont 1 tumeur multiloculaire, 2 carcinomes papillaires, 2 chromophobes et 2 tumeurs benignes finalement exclus de l’etude (nephrome kystique et adenome metanephrique). La ponction etait realisable dans 55 % des cas. Tous les liquides ponctionnes ont ete analyses. La cytologie ne retrouvait aucune cellule tumorale et l’immunohistochimie ne mettait pas en evidence de marqueur tumoral renal. Conclusion Nos resultats suggerent que la composante liquidienne est acellulaire chez des patients porteurs de carcinomes renaux classes Bosniak III ou IV. Ces donnees preliminaires pourraient expliquer l’absence de sur-risque de recidive en cas de rupture kystique peroperatoire.

Objectifs Le tabac est le principal facteur de risque controlable identifie dans le developpement des carcinomes urotheliaux. Plusieurs etudes retrospectives ont suggere une association entre l’intoxication tabagique et un pronostic defavorable chez les patients traites par cystectomie totale. L’objectif principal de ce travail etait d’evaluer ces associations dans une etude contemporaine, prospective et multicentrique. Methodes Nous avons collecte de maniere prospective, les donnees cliniques et anatomopathologiques de 295 patients dans 7 centres entre 2014 et 2015, incluant le statut tabagique (non-fumeur, sevre, actif), la duree de l’intoxication tabagique (nombre d’annees de tabagisme Resultats Sur les 237 patients analyses, 62 (26,2 %), 99 (41,8 %) et 76 (32,1 %) etaient respectivement non fumeurs, sevres et actifs. Sur les 94 patients tabagiques sevres, 24 (25,5 %) l’etaient depuis moins de 10 ans, contre 70 (74,5 %) depuis plus de 10 ans ( p p ≤ 0,01). Le tabagisme actif etait associe a l’âge, l’administration d’une chimiotherapie neoadjuvante et/ou adjuvante, et au stade tumoral (tous les p ≤ 0,03). L’analyse multivariee ajustee pour le sexe, l’âge, l’administration de chimiotherapie neoadjuvante et le nombre de RTUV montrait que le tabagisme actif etait associe a une maladie localement avancee ( p = 0,003). Le sevrage tabagique > 10 ans reduisait significativement ce risque (stade ≥ pT3, RR = 0,190 et/ou pN+, RR = 0,19) au moment de la cystectomie. Conclusion Le sevrage tabagique prolonge (> 10 ans) ameliore significativement les caracteristiques tumorales au moment de la cystectomie, ce qui est un facteur reconnu de meilleur pronostic a long terme. Les patients doivent donc etre informes des risques du tabagisme et beneficier d’un conseil de sevrage.

Objectifs La vascularisation prostatique presente une grande variabilite est reste peu decrite dans la litterature. L’objectif principal de cette etude est de decrire la vascularisation arterielle intra-prostatique, appliquee a l’embolisation arterielle prostatique (EAP) dans le cadre de l’hyperplasie benigne de prostate (HBP). Methodes Nous avons realise une etude retrospective, monocentrique, sur 40 patients ayant beneficie d’une EAP a l’hopital europeen Georges-Pompidou, Paris. Nous avons relu, avec deux radiologues, les arteriographies de ces 40 patients de maniere bilaterale (soit n = 80 modes de vascularisation observes). Pour chaque cas, nous avons decrit le nombre d’artere prostatique, leur origine, leur mode de division et leurs anastomoses eventuelles avec d’autres arteres du petit bassin. Resultats Nous avons observe une artere prostatique unique dans 70 % des cas, la presence d’une accessoire dans 29 % des cas et de deux accessoires dans 1 % des cas. L’artere prostatique naissait du tronc anterieur de l’iliaque interne dans 55 %, de l’obturatrice dans 17,5 %, de la pudendale interne dans 25 %, de l’iliaque interne dans 1 %, et de la gluteale superieure dans 1 % des cas. Concernant les modes de division, la situation la plus frequente (37 %) etait la division en une branche mediale et une branche laterale, sans anastomose. Des anastomoses avec des arteres du penis et du rectum ont ete observees dans 29 % des cas. Conclusion Nos observations nous ont permis de proposer une classification anatomique ( Fig. 1 ). Cette classification a plusieurs ambitions : ameliorer la reproductibilite de la technique d’EAP ; ameliorer sa securite en isolant les cas d’anastomoses extra prostatiques qu’il serait necessaire de proteger ; ameliorer son efficacite en discutant une adaptation de la technique en fonction du type anatomique rencontre.

Objectifs La sarcopenie (ou diminution de la masse musculaire lombaire) a ete associee dans de nombreuses tumeurs solides a un pronostic greve. L’objectif de cette etude retrospective multicentrique etait d’evaluer l’impact de la sarcopenie sur le devenir oncologique des patients traites par cystectomie totale pour une tumeur de vessie infiltrant le muscle non metastatique. Methodes Nous avons revu retrospectivement les dossiers de 201 patients atteints tumeurs de vessie cT2-4aN0-3M0 avec ou sans chimiotherapie neoadjuvante et ayant beneficie d’une cystectomie totale dans quatre etablissements francais entre 2010 et 2013. La presence d’une sarcopenie a ete mesuree par un logiciel adapte sur un scanner abdominopelvien (niveau L5) realise dans le mois avant la chirurgie. Les definitions de sarcopenie utilisees etaient celles du consensus international (Index de muscle lombaire 2 /m 2 pour les homes et 2 /m 2 pour les femmes). Un modele de regression de Cox multivarie ajustant pour les facteurs cliniques et anatomopathologiques standards a evalue l’association de la presence d’une sarcopenie avec la survenue d’une mortalite specifique et/ou globale. Resultats Les patients presentant une sarcopenie etaient significativement plus âges ( p = 0,03) et presentaient plus de comorbidites (Eastern Cooperative Oncology Group Performance Status) ( p = 0,02). En revanche, les deux groupes etaient similaires en termes d’administration de chimiotherapie neo- et adjuvante, stade pathologique T et N ( p > 0,05). Durant le suivi moyen de 4,7 annees, 105 patients sont decedes, dont 81 de la tumeur de vessie. Les patients presentant une sarcopenie presentaient une survie specifique diminuee (55 % vs 76 % ; p = 0,01) ainsi qu’une survie globale diminuee (43 % vs 71 % ; p = 0,02) par rapport aux patients ne presentant pas une sarcopenie. Cette association etait confirmee en analyse multivariee aussi bien en termes de mortalite specifique (RR, 2,04 ; p = 0,02) que de mortalite globale (RR, 1,73 ; p = 0,04). Conclusion La presence d’une sarcopenie dans le mois precedent la cystectomie totale pour tumeur de vessie infiltrant le muscle etaient associee a un devenir oncologique greve aussi bien en termes de mortalite specifique que globale.

Objectifs L’impact d’une preservation des bandelettes vasculo-nerveuses au cours d’une prostatectomie radicale sur le taux de marges chirurgicales est mal etabli dans la litterature. Nous avons observe par ailleurs que la strategie de dissection des bandelettes est parfois modifiee en peroperatoire. L’objectif de cette etude est d’evaluer la frequence des modifications de strategie en peroperatoire, et de determiner si elles influent sur le taux de marges chirurgicales. Methodes Nous avons inclus de maniere prospective 50 patients consecutifs ayant beneficie d’une prostatectomie radicale entre decembre 2016 et mars 2017 dans notre centre. Pour chaque patient, nous avons recueilli en preoperatoire le type de dissection prevue par le chirurgien pour chaque cote, puis en postoperatoire le type de dissection effectivement realise pour chaque cote. Les marges chirurgicales etaient evaluees en insu lors de l’analyse anatomopathologique. La frequence des modifications peroperatoire du type de dissection des bandelettes a ete evaluee independamment pour chaque cote (n = 100). L’association avec les marges a ete analysee par regression logistique uni- et multivariee. Resultats Les frequences des dissections prevues intra-, inter- et extra-fasciales etaient respectivement de 16 %, 60 % et 24 %. Les frequences des dissections realisees intra-, inter- et extra-fasciales etaient respectivement de 18 %, 55 % et 27 %. La strategie etait modifiee en peroperatoire dans 13 % des cas (pour n = 100), soit chez 26 % des patients. Ces modifications etaient dans 46 % des cas un rapprochement et dans 54 % des cas un eloignement de la capsule prostatique. Aucune association n’a ete mise en evidence entre les changements de strategie et le taux de marges chirurgicales en analyse uni- et multivariee. Les taux de marge etaient comparables en uni- et multivarie quel que soit le type de dissection adoptee. Conclusion Notre serie montre une frequence importante des changements de strategie en peroperatoire (26 % des patients), avec presque autant d’eloignement que de rapprochement. Dans les deux cas, on ne montre aucune difference sur le taux de marges. Ceci semble montrer que l’eloignement de la capsule en cas d’adherence est justifie pour le controle carcinologique, et que le rapprochement en cas de dissection favorable ne pejore pas la qualite de la resection.

Objectifs La reponse pathologique apres chimiotherapie neoadjuvante pour une tumeur de vessie infiltrant le muscle a ete propose comme un critere de substitution pour la survie globale. Cependant, une controverse persiste, a savoir, si l’absence de cancer residuel (ypT0) ou la presence d’une tumeur de vessie n’infiltrant pas le muscle (ypTa-pTis-pT1) est le critere de substitution optimal. Nous avons cherche a evaluer l’impact sur la survie globale de ces reponses pathologiques dans une cohorte multicentrique retrospective. Methodes Nous avons revu retrospectivement les dossiers de patients atteints de cancer urothelial de la vessie ayant recu une chimiotherapie neoadjuvante suivie d’une une cystectomie totale dans 19 institutions entre 2000 et 2013. Les patients atteints d’une tumeur de vessie cT2-4aN0M0 pN0 ont ete selectionnes. La survie globale a ete comparee entre les patients ypT0 et ypTa-pTis-pT1, y compris en analyse multivariee selon un modele de regression de Cox. Resultats Au total, 1543 patients ayant eu une chimiotherapie neoadjuvante suivie d’une cystectomie totale ont ete inclus ; 257 etaient ypT0N0 et 207 etaient ypTa-pTis-pT1 sur les pieces operatoires. Selon la methode de Kaplan–Meier, la survie globale chez les patients ypT0 et ypTa-pTis-pT1, respectivement, etaient de 186,7 mois et de 138 mois, respectivement ( p = 0,58). En analyse multivariee, les patients ypTa-pTis-pT1N0 ypT0N0 presentaient un risque diminue de mortalite globale (RR 0,36, 95 % IC 0,23–0,67 et RR 0,28, 95 % IC 0,17–0,47, respectivement) par rapport aux patients pT2N0. Conclusion Le stade pathologique ypT0 sur les pieces operatoires de cystectomie totale est un bon predicteur de la survie globale chez les patients ayant recu une chimiotherapie neoadjuvante. En comparaison, les patients ypTa-pTis-pT1 n’avaient pas un risque de mortalite globale superieur et sont eux aussi de bon pronostic. Ces resultats peuvent permettre une meilleure information des patients quant a leur pronostic en pratique quotidienne.

Objectifs La chimiotherapie neoadjuvante a la cystectomie totale (CysT) fait partie des recommandations francaises et europeennes. Cependant, celle-ci n’est pas encore realisee systematiquement en pratique quotidienne notamment en raison d’une perception de chirurgie plus morbide apres chimiotherapie. D’ou l’etude des complications postoperatoires et de la reponse oncologique de la chimiotherapie neoadjuvante des tumeurs de vessie infiltrant le muscle. Methodes Il s’agit d’une etude retrospective mulitcentrique (2 CHU) entre janvier 2010 et juillet 2015. Parmi les 203 patients ayant eu une CysT pour carcinome urothelial de vessie 95 (46,8 %) avaient recu une chimiotherapie neoadjuvante (CTNA). La classification de Clavien a ete utilisee comme critere de jugement principal pour les complications postoperatoires. La reponse a la chimiotherapie neoadjuvante etait definie par un stade ypT Resultats L’âge moyen des patients etait de 68,2 ans (68,1 groupe CTNA vs 68,8 groupe chimio-naif p = ns). Il n’y avait pas de difference significative de complications postoperatoires ≥ Clavien 2 : 46,3 % dans le groupe chimiotherapie versus 54,6 % dans le groupe chimio-naif ( p = 0,23). Pour les complications severes (Clavien > 2), aucune difference n’etait retrouve entre les 2 groupes ( p = 0,19). Un patient est decede dans le groupe CTNA versus 3 dans le groupe chimio-naif. Dans le groupe CTNA, 56,8 % des patients etaient repondeurs et 43,2 % etaient non-repondeurs ; 35,8 % des patients du groupe CTNA etaient ypT0N0 sur la piece de CysT. Conclusion La chimiotherapie neoadjuvante semble etre sure et n’augmente pas le risque de complications postoperatoires. En revanche la reponse oncologique a la chimiotherapie neoadjuvante parait etre tres heterogene. Cela doit nous encourager a poursuivre des etudes prospectives afin de mieux selectionner les patients eligibles a une chimiotherapie neoadjuvante avant CysT.

Objectifs Evaluer les caracteristiques histologiques des pieces de resection transuretrale de la vessie en tomographie par coherence optique plein champ (FFOCT) avant leur analyse anatomopathologique finale. Methodes Vingt-quatre patients consecutifs soumis a une resection transuretrale de vessie pour tumeur, ont ete inclus dans cette etude. Pour chaque patient, un copeau de resection a ete analyse en imagerie par coherence optique plein champ, immediatement apres son prelevement. Deux coupes optiques ont ete realisees, une sur chacune des faces du copeau, a 40 μm de profondeur. Les images obtenues ont ete analysees en aveugle par deux internes en urologie prealablement inities a l’analyse histologique de la vessie. La presence de carcinome urotheliale, de musculeuse, et d’un envahissement carninomateux de la musculeuse, a ete rapporte. Une analyse de correlation anatomopathologique a ete ensuite realisee. Resultats La duree moyenne de la procedure etait de 3 [2–4] minutes. En histologie standard (coloration HES), aucun artefact n’a ete note. Parmi les 24 copeaux analyses, 11 etaient classees pTa, 3 pT1, 1 carcinome in situ, et 9 etaient indemnes de proliferation carcinomateuse. La concordance entre le resultat de l’analyse optique et histologique pour la presence de tumeur, de musculeuse, d’un envahissement du chorion et d’un envahissement de la musculeuse etait correcte dans respectivement 21/24 (87,5 %), 19/24 (79 %), 14/24 (58 %) et 24/24 (100 %) des cas. Les sensibilites, specificites et valeurs predictives sont rapportees dans le Tableau 1 . Conclusion La FFOCT des copeaux de resection de vessie semblait etre une technique faisable, avec des resultats concordants a ceux de l’analyse histologique dans la majorite des cas.

- Abstract
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., (Copyright © 2024 European Association of Urology.

Purpose: To evaluate biopsy-related complications and detection rates of any PCa and clinically significant PCa (csPCa, intended as grade group ≥ 2) between MRI-targeted TP fusion biopsies (TPBx) and TR ones (TRBx)., Methods: We performed a multicentric study on 4841 patients who underwent fusion biopsy between 2016 and 2023. A case-control matching was performed to find comparable cohorts of 646 TPBx and 646 TRBx. Mean T test and Pearson chi-square tests were used to compare continuous and categorical variables., Results: Baseline characteristics were comparable between the cohorts, except for target location with a higher rate of anterior lesions in TPBx group. Complications were rare and no difference was found between the groups, with similar rates of infections after TRBx and TPBx (N = 5 (0.8%) vs N = 2 (0.3%), p 0.45). All patients in TRBx and 90.1% in TPBx group received antibiotic prophylaxis. A higher csPCa detection rate was found in TPBx over the group (50.5% vs 36.2%, p < 0.001). On average, positive targeted cores were increased in TPBx group, for any PCa (1.6 vs 1.4, p 0.04) and csPCa (1.0 vs 0.8, p 0.02). Among the limitations of study, we acknowledge the retrospective design and the possible under-reporting of complications., Conclusions: MRI-targeted fusion TPBx achieves a significantly higher csPCa detection than TRBx, with a diagnostic advantage for apical and anterior lesions. No significant differences were found in terms of complications that were rare in both groups, considering a widespread adoption of antibiotic prophylaxis., (© 2024. The Author(s).)

- Abstract
Background and Objective: Histopathological examination of surgical specimens for benign prostatic hyperplasia (BPH) can detect incidental prostate cancer (iPCa). The aim of our study was to develop a predictive model for iPCa diagnosis for patients for whom BPH surgery is being considered., Methods: We conducted a retrospective analysis of medical files for patients who underwent BPH surgery in three academic centers between 2012 and 2022. Patients diagnosed with PCa before surgery were excluded. We calculated the global iPCa rate, and the clinically significant iPCa rate (grade group ≥2). Univariate and multivariable regression models were used to assess factors predictive of iPCa. The area under the receiver operating characteristic curve (AUC) was compared for each risk factor and for the global model. We used χ
2 automated interaction detection (CHAID) for decision tree analysis., Key Findings and Limitations: We included 2452 patients in the analysis, of whom 247 (10.0%) had iPCa, which was clinically significant in 49/247 cases (20.2%). Multivariable analysis revealed that age and prostate-specific antigen density (PSAD) were independent predictive factors for iPCa diagnosis. The AUC for a model including age and PSAD was 0.65. CHAID analysis revealed that patients with PSAD >0.1 ng/ml/cm3 had an iPCa risk of 23.4% (χ2 = 52.6; p < 0.001). For those patients, age >72 yr increased the iPCa risk to 35.4% (χ2 = 11.1, p = 0.008). Our study is mainly limited by its retrospective design., Conclusions and Clinical Implications: Age and PSAD were independent risk factors for iPCa diagnosis. The combination of age >72 yr and PSAD >0.1 ng/ml/cm3 was associated with an iPCa rate of 35.4%., Patient Summary: We performed a study to find predictors of prostate cancer for patients undergoing surgery for benign enlargement of the prostate. Our model can identify patients at risk, and diagnose their cancer before surgery. This could avoid unnecessary or harmful procedures., (Copyright © 2024 The Author(s). Published by Elsevier B.V.

- Abstract
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., (Copyright © 2024 European Association of Urology. Published by Elsevier B.V.

- Abstract
Purpose of Review: This review aims to provide an update on the results of studies published in the last two years involving the development of sustainable practices in hospital and operating theaters (OT)., Recent Findings: Recently, many studies evaluated various initiatives to better understand the environmental impact of the OT but also to minimize its environmental impact. Many trials evidenced the positive impact of the instrument's reuse using an appropriate reprocessing procedure. Better waste segregation is associated with a reduction of produced waste and contributes to a significant reduction in CO 2 equivalent emissions. Regarding anaesthetic gas, Desflurane is known to have the worst environmental impact and the majority of the study evidenced that its reduction permits to drastically reduce greenhouse gas emission of the OT., Summary: Greening the OT necessitates climate-smart actions such as waste reduction, the improvement of reusable instruments, recycling of our waste and better anaesthetic gas management. Within the last two years, many efforts have been made to reduce and better segregate waste produced in the OT and also to better understand the environmental impact of disposable and reusable devices., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Background: Prostate Imaging Reporting and Data System (PI-RADS) 3 lesions, identified through multiparametric magnetic resonance imaging (mpMRI), present a clinical challenge due to their equivocal nature in predicting clinically significant prostate cancer (csPCa). Aim of the study is to improve risk stratification of patients with PI-RADS 3 lesions and candidates for prostate biopsy., Methods: A cohort of 4841 consecutive patients who underwent MRI and subsequent MRI-targeted and systematic biopsies between January 2016 and April 2023 were retrospectively identified from independent prospectively maintained database. Only patients who have PI-RADS 3 lesions were included in the final analysis. A multivariable logistic regression analysis was performed to identify covariables associated with csPCa defined as International Society of Urological Pathology (ISUP) grade group ≥2. Performance of the model was evaluated using the area under the receiver operating characteristic curve (AUC), calibration, and net benefit. Significant predictors were then selected for further exploration using a Chi-squared Automatic Interaction Detection (CHAID) analysis., Results: Overall, 790 patients had PI-RADS 3 lesions and 151 (19%) had csPCa. Significant associations were observed for age (OR: 1.1 [1.0-1.1]; p = 0.01) and PSA density (OR: 1643 [2717-41,997]; p < 0.01). The CHAID analysis identified PSAd as the sole significant factor influencing the decision tree. Cut-offs for PSAd were 0.13 ng/ml/cc (csPCa detection rate of 1% vs. 18%) for the two-nodes model and 0.09 ng/ml/cc and 0.16 ng/ml/cc for the three-nodes model (csPCa detection rate of 0.5% vs. 2% vs. 17%)., Conclusions: For individuals with PI-RADS 3 lesions on prostate mpMRI and a PSAd below 0.13, especially below 0.09, prostate biopsy can be omitted, in order to avoid unnecessary biopsy and overdiagnosis of non-csPCa., (© 2024.

- Abstract
Purpose: Magnetic resonance imaging (MRI) is a promising tool for risk assessment, potentially reducing the burden of unnecessary prostate biopsies. Risk prediction models that incorporate MRI data have gained attention, but their external validation and comparison are essential for guiding clinical practice. The aim is to externally validate and compare risk prediction models for the diagnosis of clinically significant prostate cancer (csPCa)., Methods: A cohort of 4606 patients across fifteen European tertiary referral centers were identified from a prospective maintained database between January 2016 and April 2023. Transrectal or transperineal image-fusion MRI-targeted and systematic biopsies for PI-RADS score of ≥ 3 or ≥ 2 depending on patient characteristics and physician preferences. Probabilities for csPCa, defined as International Society of Urological Pathology (ISUP) grade ≥ 2, were calculated for each patients using eight models. Performance was characterized by area under the receiver operating characteristic curve (AUC), calibration, and net benefit. Subgroup analyses were performed across various clinically relevant subgroups., Results: Overall, csPCa was detected in 2154 (47%) patients. The models exhibited satisfactory performance, demonstrating good discrimination (AUC ranging from 0.75 to 0.78, p < 0.001), adequate calibration, and high net benefit. The model described by Alberts showed the highest clinical utility for threshold probabilities between 10 and 20%. Subgroup analyses highlighted variations in models' performance, particularly when stratified according to PSA level, biopsy technique and PI-RADS version., Conclusions: We report a comprehensive external validation of risk prediction models for csPCa diagnosis in patients who underwent MRI-targeted and systematic biopsies. The model by Alberts demonstrated superior clinical utility and should be favored when determining the need for a prostate biopsy., (© 2024.

- Abstract
Purpose: Utility of prostate-specific antigen density (PSAd) for risk-stratification to avoid unnecessary biopsy remains unclear due to the lack of standardization of prostate volume estimation. We evaluated the impact of ellipsoidal formula using multiparametric magnetic resonance (MRI) and semi-automated segmentation using tridimensional ultrasound (3D-US) on prostate volume and PSAd estimations as well as the distribution of patients in a risk-adapted table of clinically significant prostate cancer (csPCa)., Methods: In a prospectively maintained database of 4841 patients who underwent MRI-targeted and systematic biopsies, 971 met inclusions criteria. Correlation of volume estimation was assessed by Kendall's correlation coefficient and graphically represented by scatter and Bland-Altman plots. Distribution of csPCa was presented using the Schoots risk-adapted table based on PSAd and PI-RADS score. The model was evaluated using discrimination, calibration plots and decision curve analysis (DCA)., Results: Median prostate volume estimation using 3D-US was higher compared to MRI (49cc[IQR 37-68] vs 47cc[IQR 35-66], p < 0.001). Significant correlation between imaging modalities was observed (τ = 0.73[CI 0.7-0.75], p < 0.001). Bland-Altman plot emphasizes the differences in prostate volume estimation. Using the Schoots risk-adapted table, a high risk of csPCa was observed in PI-RADS 2 combined with high PSAd, and in all PI-RADS 4-5. The risk of csPCa was proportional to the PSAd for PI-RADS 3 patients. Good accuracy (AUC of 0.69 and 0.68 using 3D-US and MRI, respectively), adequate calibration and a higher net benefit when using 3D-US for probability thresholds above 25% on DCA., Conclusions: Prostate volume estimation with semi-automated segmentation using 3D-US should be preferred to the ellipsoidal formula (MRI) when evaluating PSAd and the risk of csPCa., (© 2024.

- Abstract
Benign prostate hyperplasia (BPH) is caused by the nonmalignant enlargement of the transition zone of the prostate gland, leading to lower urinary tract symptoms. Although current medical treatments are unsatisfactory in many patients, the limited understanding of the mechanisms driving disease progression prevents the development of alternative therapeutic strategies. The probasin-prolactin (Pb-PRL) transgenic mouse recapitulates many histopathological features of human BPH. Herein, these alterations parallel urodynamic disturbance reminiscent of lower urinary tract symptoms. Single-cell RNA-sequencing analysis of Pb-PRL mouse prostates revealed that their epithelium mainly includes low-androgen signaling cell populations analogous to Club/Hillock cells enriched in the aged human prostate. These intermediate cells are predicted to result from the reprogramming of androgen-dependent luminal cells. Pb-PRL mouse prostates exhibited increased vulnerability to oxidative stress due to reduction of antioxidant enzyme expression. One-month treatment of Pb-PRL mice with anethole trithione (ATT), a specific inhibitor of mitochondrial ROS production, reduced prostate weight and voiding frequency. In human BPH-1 epithelial cells, ATT decreased mitochondrial metabolism, cell proliferation, and stemness features. ATT prevented the growth of organoids generated by sorted Pb-PRL basal and LSC
med cells, the two major BPH-associated, androgen-independent epithelial cell compartments. Taken together, these results support cell plasticity as a driver of BPH progression and therapeutic resistance to androgen signaling inhibition, and identify antioxidant therapy as a promising treatment of BPH., Competing Interests: Disclosure Statement O.P. holds a patent on ATT repositioning for BPH treatment. He participated in initial study design, but had no role in data collection, analysis, and interpretation, or writing of the manuscript., (Copyright © 2024 American Society for Investigative Pathology.
