Analysis of active surveillance uptake for localized prostate cancer in Quebec in 2016: A Canadian bicentric study and comparison with 2010 data.

INTRODUCTION: Active surveillance (AS) has emerged as a primary management strategy for low-risk prostate cancer (PC) patients. We aimed to assess AS uptake over a 1-year snapshot throughout Quebec and to compare it to 2010 multicentric Canadian data. METHODS: A retrospective chart review and data collection was performed in 1 academic and 2 non-academic community centres from Quebec, among men identified in 2016 with localized T1c-T2c PC on biopsy, fulfilling NCCN criteria of low-risk (LR)-PC, including very-low-risk (VLR) and non-VLR-PC, and favourable-intermediate risk (FIR)-PC. AS adherence was defined when chosen as initial strategy, without any radical treatment within 6 months. RESULTS: Overall, 259 patients fulfilled the inclusion criteria with 50.2% of VLR-PC patients. At 6 months, 81% patients in the LR group and 65% in the FIR group were considered as adherent to AS, in both centres, but with an increased use of AS in the community centres compared to 2010 data. The rates of AS maintenance decreased at 12 months to respectively 69% and 58%. Among the VLR group, the rate of initiation was 98% and decreased to 85% at 12 months. CONCLUSION: Our data suggest that the majority of low-risk PC patients indeed initiated an AS in 2016, with even a greater proportion of VLR-PC patients compared to 2010. This ideal strategy should be encouraged and improved at 12 months, and assessed with recent data and longer follow-up.

[Early detection of prostate cancer: Towards a new paradigm?] / Détection précoce du cancer de la prostate : vers un nouveau paradigme ?

Prostate cancer (PCa) is a public health issue. The diagnostic strategy for PCa is well codified and assessed by digital rectal examination, PSA testing and multiparametric MRI, which may or may not lead to prostate biopsies. The formal benefit of organized PCa screening, studied more than 10 years ago at an international scale and for all incomers, is not demonstrated. However, diagnostic and therapeutic modalities have evolved since the pivotal studies. The contribution of MRI and targeted biopsies, the widespread use of active surveillance for unsignificant PCa, the improvement of surgical techniques and radiotherapy… have allowed a better selection of patients and strengthened the interest for an individualized approach, reducing the risk of overtreatment. Aiming to enhance coverage and access to screening for the population, the European Commission recently promoted the evaluation of an organized PCa screening strategy, including MRI. The lack of screening programs has become detrimental to the population and must shift towards an early detection policy adapted to the risk of each individual.

Volumetric and functional outcomes at 1-year between percutaneous-ablation and partial-nephrectomy for T1b renal tumors.

INTRODUCTION: Indication for percutaneous-ablation (PA) is gradually expanding to renal tumors T1b (4-7cm). Few data exist on the alteration of renal functional volume (RFV) post-PA. Yet, it is a surrogate marker of post partial-nephrectomy (PN) glomerular filtration rate (GFR) impairment. The objective was to compare RFV and GFR at 1-year post-PN or PA, in this T1b population. METHODS: Patients with unifocal renal tumor≥4cm treated between 2014 and 2019 were included. Tumor, homolateral (RFVh), contralateral RFV, and total volumes were assessed by manual segmentation (3D Slicer) before and at 1 year of treatment, as was GFR. The loss of RFV, contralateral hypertrophy, and preservation of GFR were compared between both groups (PN vs. PA). RESULTS: 144 patients were included (87PN, 57PA). Preoperatively, PA group was older (74 vs. 59 years; P<0.0001), had more impaired GFR (73 vs. 85mL/min; P=0.0026) and smaller tumor volume(31.1 vs. 55.9cm3; P=0.0007) compared to PN group. At 1 year, the PN group had significantly more homolateral RFV loss (-19 vs. -14%; P=0.002), and contralateral compensatory hypertrophy (+4% vs. +1,8%; P=0.02, respectively). Total-RFV loss was similar between both (-21.7 vs. -19cm3; P=0.07). GFR preservation was better in the PN group (95.9 vs. 90.7%; P=0.03). In multivariate analysis, age and tumor size were associated with loss of RFVh. CONCLUSION: For renal tumors T1b, PN is associated with superior compensatory hypertrophy compared with PA, compensating for the higher RFVh loss, resulting in similar ΔRFV-total between both groups. The superior post-PN GFR preservation suggests that the preserved quantitative RFV factor is insufficient. Therefore, the underlying quality of the parenchyma would play a major role in postoperative GFR.

Prognostic significance of PI-RADS 5 lesions in patients treated by radical prostatectomy.

PURPOSE: To analyse the pathological features and survival of patients with a PI-RADS 5 lesion on pre-biopsy MRI. METHODS: We extracted from a European multicentre prospectively gathered database the data of patients with a PI-RADS 5 lesion on pre-biopsy MRI, diagnosed using both systematic and targeted biopsies and subsequently treated by radical prostatectomy. The Kaplan-Meier model was used to assess the biochemical-free survival of the whole cohort and univariable and multivariable Cox models were set up to study factors associated with survival. RESULTS: Between 2013 and 2019, 539 consecutive patients with a PI-RADS 5 lesion on pre-biopsy MRI were treated by radical prostatectomy and included in the analysis. Follow-up data were available for 448 patients. Radical prostatectomy and lymph node dissection specimens showed non-organ confined disease in 297/539 (55%), (including 2 patients with a locally staged pT2 lesion and lymph node involvement (LNI)). With a median follow-up of 25 months (12-39), the median biochemical recurrence-free survival was 54% at 2 years (95% CI 45-61) and 28% at 5 years (95% CI 18-39). Among the factors studied, MRI T stage [T3a vs T2 HR 3.57 (95%CI 1.78-7.16); T3b vs T2 HR 6.17 (95% CI 2.99-12.72)] and PSA density (HR 4.47 95% CI 1.55-12.89) were significantly associated with a higher risk of biochemical recurrence in multivariable analysis. CONCLUSION: Patients with a PI-RADS 5 lesion on pre-biopsy MRI have a high risk of early biochemical recurrence after radical prostatectomy. MRI T stage and PSA density can be used to improve patient selection and counselling.

French AFU Cancer Committee Guidelines - Update 2022-2024: prostate cancer - Diagnosis and management of localised disease.

OBJECTIVE: The objective of the French Urology Association Cancer Committee is to propose an update of the recommendations for the diagnosis and management of prostate cancer (PC). METHODS: A systematic review of the literature from 2020 to 2022 was conducted by the CCAFU on the diagnosis and therapeutic management of localised PC, while evaluating the references and their levels of evidence. RESULTS: The recommendations specify the genetics, epidemiology and means of diagnosing prostate cancer, as well as the notions of screening and early detection. MRI, the gold standard imaging examination for localised cancer, is recommended before prostate biopsies are performed. The transperineal approach reduces the risks of infection. The therapeutic methods are described and recommended according to the clinical context. Active surveillance is the gold standard of treatment for tumours with a low risk for progression. Early salvage radiotherapy is recommended in case of biochemical recurrence after radical prostatectomy. Imaging, particularly molecular imaging, helps to guide the decision-making in the event of biochemical recurrence after local treatment, but should not delay early salvage radiotherapy in the event of biological recurrence after radical prostatectomy. CONCLUSION: This update of the French recommendations should help to improve the management of patients with PC.

French AFU Cancer Committee Guidelines - Update 2022-2024: prostate cancer - Management of metastatic disease and castration resistance.

OBJECTIVE: The objective of the French Urology Association Cancer Committee is to propose an update of the recommendations for the management of prostate cancer. METHODS: A systematic review of the literature from 2020 to 2022 was conducted by the CCAFU on the elements of therapeutic management of metastatic and castration-resistant prostate cancer (PC), while evaluating the references and their levels of evidence. RESULTS: Androgen deprivation therapy (ADT) remains the standard treatment for metastatic prostate cancer. ADT intensification is now a standard of care in the management of metastatic prostate cancer. This intensification is discussed in relation to the patient and the characteristics of the disease. For all metastatic hormone-sensitive PC (synchronous and metachronous), the overall survival benefit associated with good tolerability makes the combination of ADT and novel hormonal agents (NHA) a standard. For patients with high-volume/high-risk de novo metastatic disease, treatment with docetaxel in addition to ADT + NHA can be discussed for eligible patients. In patients with castration-resistant prostate cancer (CRPC), the contribution of new therapies that have become available in recent years, as well as the advent of precision medicine, help to improve the control of tumour progression and survival, and highlight the value of testing for alterations in DNA repair genes within the tumour tissue or constitutionally. CONCLUSION: This update of the French recommendations should help to improve the management of patients with prostate cancer.

[Recent advances in the management of localized high-risk prostate cancer: An update by the Prostate Cancer Committee of the French Association of Urology]. / Avancées récentes dans la prise en charge du cancer de la prostate localisé à haut risque : mise au point par le Comité Prostate de l'Association française d'urologie.

INTRODUCTION: The risk of recurrence is increased in localized high-risk prostate cancer (PCa). The implementation of an appropriate diagnostic and therapeutic strategy is essential. The objective of this update by the Prostate Committee of the French Association of Urology was to report the most recent data in the management of localized high-risk PCa. MATERIAL AND METHODS: This update is based on the data available in the literature on localized high-risk PCa. A PubMed search and narrative review of the recent data were performed in March 2022. RESULTS: Compared with conventional imaging, PET-PSMA is more effective for the diagnosis of lymph nodes and distant metastases. Two recent randomized clinical trials have failed to prove the oncologic benefit of extended pelvic lymph node dissection during radical prostatectomy (RP). Postoperatively, early salvage radiotherapy is the standard of care, with adjuvant radiotherapy becoming an option in case of unfavorable pathological criteria (ISUP 4-5, pT3±positive margins) in young patients. Although promising, perioperative systemic therapies (chemotherapy, second-generation hormonotherapy) cannot be recommended at this time when the patient is treated by RP. Regarding radiotherapy, prophylactic lymph node irradiation during prostatic irradiation was associated with improved biochemical and metastasis-free survival in a recent randomized trial but it is still controversial. Since the publication of the results of the STAMPEDE trial, the addition of abiraterone acetate to radiation-hormone therapy should be considered the new standard of care for patients with localized (very) high-risk PCa, according to the inclusion criteria of the study. CONCLUSION: The most recent data of the literature regarding the management of high-risk localized PCa redefine the diagnostic performance of molecular imaging, the timing of postoperative radiotherapy, the oncologic benefit of pelvic lymph node treatment, and the intensification of systemic therapies.

Posterior transperitoneal robot-assisted partial nephrectomy in the treatment of renal tumors: Feasibility of a hybrid approach.

PURPOSE: Robot-assisted partial nephrectomy (RAPN) for posterior renal tumors may be performed through anterior (transperitoneal) or posterior (retroperitoneal) approach depending on surgeon's expertise. We propose herein a surgical artifice using daVinci Xi system to combine advantages of both approaches. MATERIALS AND METHODS: From November 2019 to November 2020, patients with posterior renal mass, candidate for RAPN were prospectively included after informed consent. After positioning patient in lateral position, daVinci Xi system was docked on tumor side, to initiate transperitoneal procedure. Posterolateral dissection of perinephric space along fascia retrorenalis was conducted until psoas major muscle was exposed. Three additional robotic ports were then inserted in lumbar space, and RAPN was resumed after rotating daVinci Xi boom. Demographics, tumor characteristics, perioperative outcomes, estimated glomerular filtration rate (eGFR) and follow-up data were analyzed. RESULTS: Ten consecutive patients underwent RAPN with the modified technique. All cases were performed robotically, without modification of port placement. Median (range) tumor diameter was 37 (21-48mm) with median RENAL score of 8 (4-10) Median operative time and warm ischemia time were respectively 128min (70-180min) and 19min (14-22). One patient had a Clavien-Dindo grade II complication. At median follow-up of 13 months (6-18), all patients had eGFR comparable to baseline. CONCLUSIONS: We report the feasibility and safety of a new hybrid posterior transperitoneal approach for RAPN using daVinci Xi system. Limitations include the absence of RENAL score>10 and pT2 tumors. Greater experience is needed to assess learning curve for surgeons untrained to robotic lomboscopy.

[DNA repair gene alterations testing in prostate cancer : A practical update by the prostate cancer committee of the french association of urology]. / Recherche d'altérations des gènes de réparation de l'ADN dans le cancer de la prostate : mise au point pratique du Comité de cancérologie de l'association française d'urologie.

INTRODUCTION: Current therapeutic developments in prostate cancer (PCa) tend to increasingly personalize the treatment strategy, in particular as a function of tumor genomics. Recently, poly ADP-ribose polymerase (PARPi) inhibitors have shown their efficacy at the stage of castration resistance, in case of alteration of DNA repair genes in tumor tissue. MATERIAL AND METHODS: A narrative review was carried out on recent data in the literature since 2000. A consensus among the members of the Committee was obtained in order to synthesize the current data, with a particular focus on the practical considerations regarding indications and developments of molecular testing circuits concerning DNA repair genes, for theranostics purpose. RESULTS: The establishment of an efficient molecular testing network is based on the multidisciplinary organization of the various actors and the coordination of all material resources. Its goal is the routine search for somatic mutations (in tumor tissue) of BRCA1/2 genes in patients who may benefit from PARPi. The current indications are for BRCA1 or 2 mutated castration-resistant metastatic PCa after next-generation hormone therapy failure. The demand for molecular testing must be decided in the tumor board, giving priority to archived tissue less than 10 years old. In case of unsuccess, biopsies of the primary or metastases, or even analysis of circulating tumor DNA, may be necessary. Any demand for a genetic test on tumor tissue must be accompanied by detailed information for the patient on the possible familial consequences, in case of associated germline mutation. CONCLUSION: This article aims to guide the practical implementation of molecular testing circuits for DNA repair genes alterations, in order to guide the therapeutic management of patients with advanced PCa.

Narrative review of PET/CT performances at biochemical recurrence in prostate cancer after radical prostatectomy and impact on patient disease management: Revue narrative à propos des performances de la TEP/TDM en cas de récidive biochimique après prostatectomie radicale dans le cancer de la prostate et impact sur la prise en charge des patients.

Patients treated by radical prostatectomy (RP) for localized prostate cancer (PCa) may experience biochemical recurrence (BCR) in approximately 30% of cases. Recently, advances in imaging modalities and in particular Positron-Emission Tomography with computed tomography (PET/CT) imaging allow for better detection and characterization of lesions outside the prostatic bed at recurrence. Thus, treatment at BCR can be significantly improved by a tailored strategy based on new generation imaging. A more precise and accurate staging of the disease at recurrence paves the way to more appropriate treatment, potentially translating into better survival outcomes of these patients. This review therefore highlights the interest of PET/CT at the time of BCR, its superiority over standard imaging in terms of staging, and its impact on guiding the different therapeutic possibilities depending on the site, number, and volumes of recurrence. Indeed, we will discuss below about different strategies and their indications: salvage radiotherapy of the prostate bed, systemic therapies, stereotactic body radiotherapy and others therapeutical strategies. The various innovative approaches based on PET/CT implementation are partly underway within protocol trials to prove their benefits on clinically meaningful endpoints. © 2022 Elsevier Masson SAS.

How PET-CT is Changing the Management of Non-metastatic Castration-resistant Prostate Cancer?: Comment la TEP-TDM Peut Modifier la Prise en Charge du Cancer de la Prostate Non Métastatique Résistant à la Castration ?

INTRODUCTION: The aim of this narrative review conducted by the Prostate Cancer Committee of the French Association of Urology (CC-AFU) was to provide an update on the current evidence for the impact of PET/CT in the management of men with non-metastatic castration-resistant prostate cancer (nmCRPC). MATERIAL AND METHODS: This review is based on data available in the literature on PET/CT imaging for staging nmCRPC patients. A PubMed search and narrative review of the data were performed in March 2022. Only articles in French or English were considered. RESULTS: Current guidelines recommend bone scan and CT scan as standard imaging modalities for staging and follow-up of patients with nmCRPC. Nearly one-third of asymptomatic patients with presumed nmCRPC ultimately have metastatic disease on conventional imaging. Increasing reports have shown that conventional imaging has limited accuracy in detecting metastatic disease in nmCRPC patients, leading to the development of next-generation imaging techniques. In a retrospective study, 18F-choline PET/CT detected distant metastases in 27/58 high-risk nmCRPC patients with prior negative conventional imaging. The implementation of radiolabeled ligands of the prostate-specific membrane antigen (PSMA) PET/CT in staging strategy has resulted in metastasis detection in 45% to 98% of patients with presumptive nmCRPC on conventional imaging. Such an early diagnosis of metastatic CRPC may allow patients to be referred for metastasis-directed therapies (i.e. stereotactic body radiotherapy), aimed at prolonging the efficacy of systemic therapies and improving clinical outcomes. However, current data are not strong enough to recommend this strategy, which must be properly evaluated in clinical trials. Indeed, the use of molecular imaging may lead to inappropriate undertreatment if the second-generation androgen receptor inhibitors (darolutamide, enzalutamide, apalutamide), which prolong life, are not used in the subgroup of patients with high PSA velocity (PSA doubling time <10 months). CONCLUSION: Implementation of PSMA-PET/CT in the staging strategy would result in a migration of disease stage to extra-pelvic, M1 disease in at least half of presumed nmCRPC patients. The unprecedented accuracy of PSMA-PET/CT may pave the way for a more personalized treatment strategy. However, no data yet support this strategy for all nmCRPC patients as no oncologic benefit of early detection of M1 disease or MDT has been demonstrated. © 2022 Elsevier Masson SAS.

Management of long ureteral stenosis: Alternatives to indwelling ureteral stents.

OBJECTIF: Evaluate kidney autotransplantation (KAT) and ileal ureter substitution (IUS) practice and outcome as alternatives to indwelling ureteral stents for the management of long ureteral stenosis (US). MATERIAL: We included all patients treated for US with KAT or IUS in 5 French university urology centers between 2010 and 2018. We excluded US due to urothelial carcinoma. Primary endpoint was the preservation of ipsilateral kidney and renal function without any urinary diversion. RESULTS: 22 patients were treated with KAT (n=8, 36.4%) and IUS (n=14, 63.6%). Mean US length was 4.6cm and 6cm (P=0.52) in KAT and IUS groups respectively. US etiologies were lithiasis, iatrogenic, retroperitoneal fibrosis or extrinsic compression. US level was varied. The surgery was described as difficult because of peritoneal adhesions or major peri-ureteral fibrosis. Mean operating time and hospital stay were 336 and 346minutes (P=0.87) and 8 and 15 days respectively (P=0.001). Postoperative complications were mostly Clavien ≤2 (n=17, 77.3%). Revision surgery was required in the KAT group in 3 cases (37.5%), for textiles, renal vein thrombosis and anastomotic leak, none in the IUS group. The mean follow-up was 15.7 months. All but one (in the KAT group) ipsilateral kidneys were preserved, without renal function impairment (Δcreat +2.1 vs. +2.4µmol/l respectively, P=0.67), nor urinary diversion. CONCLUSION: KAT and IUS are safe alternatives whose indication depends on surgeons expertise. Our study pointed out the scarcity of this practice suggesting the need to refer patients to expert centers. LEVEL OF EVIDENCE: 3.

Administration of neoadjuvant chemotherapy for muscle-invasive bladder cancer in real life: Are urologists still too cautious?

INTRODUCTION: Neoadjuvant chemotherapy (NAC) is now recommended to treat muscle-invasive bladder cancer (MIBC) but is not always executed in real life. This study aims to evaluate the proportion of patients with MIBC who receive an optimal NAC, and to present the predictive factors of its achievement. METHODS: This monocenter retrospective study included all the patients who underwent radical cystectomy for≥pT2NxM0 MIBC between 2013, January and 2018, December. NAC consisted in 4-6 cycles of MVAC (methotrexate, vinblastine, adriamycin, and cisplatin) or 4 cycles of GC (gemcitabin, and carboplatin). Demographic (sex, age, ECOG-PS, glomerular filtration rate [GFR], and cN stage), surgical (urinary derivation, time of surgery, blood loss, and complications), and oncological characteristics were analyzed. Multivariate analysis are made to find predictors of administration of NAC. RESULTS: One hundred and twenty-seven patients were included. Thirty received CNA (24%). Patients who underwent CNA were younger, with better ECOG and better GFR. Multivariate analysis showed that cN+ stage and better GFR were significantly associated to administration of NAC. Eight patients (27%) couldn't receive an optimal treatment due to toxicity. Perioperative complication rates were similar, with or without NAC. Patients who underwent NAC had a worse GFR after treatment (-17 versus +5mL/min, P<0.01). CONCLUSION: Due to the risks of toxicity, NAC can only be proposed to selected population, which is not the current patients. Immunotherapy could allow to treat more patients because of better tolerance. LEVEL OF EVIDENCE: 3.

[Impact of the COVID-19 pandemic on surgical activity within academic urological departments in Paris]. / Impact de la pandémie de COVID-19 sur l'activité chirurgicale au sein des services d'urologie de l'Assistance Publique ­ Hôpitaux de Paris.

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.

Sexual dysfunction after elective laparoscopic or endovascular abdominal aortic aneurysm repair in men.

INTRODUCTION: Infrarenal abdominal aortic aneurysm (AAA) repair can lead to ejaculation and erection troubles in men. There are few studies on sexual dysfunction after endovascular repair (EVAR) but they suggest less retrograde ejaculation than after open repair. We assessed the sexual dysfunction and ejaculation troubles after elective laparoscopic repair or EVAR. METHODS: We conducted a monocentric prospective study on 124 patients undergoing AAA repair between 2013 and 2015. Sexual function was evaluated using the IIEF-15 questionnaire and questions on ejaculation. RESULTS: Only 45 patients (36.3%) accepted to complete the IIEF preoperatively with 20-37.8% having preoperative sexual dysfunction. Among them, 21 (46.7%) accepted to complete the questionnaire at 3, 6 and 12 months. Mean age at inclusion was 65±5.6 years in the laparoscopic group and 77±10.5 years in the EVAR group (P=0.003). Erectile and sexual function were slightly improved at 12 months in the laparoscopic group (+1.4 for erectile score and +4.6 for IIEF score) with no significant difference (P=0.83 and 0.74) whereas 8 patients (61.5%) had persistent ejaculation troubles at 3 months. In the EVAR group, patients had moderate sexual dysfunction at baseline without improvement at 12 months, but only one patient reported ejaculation troubles. CONCLUSIONS: Most patients eligible for AAA repair present with baseline erectile and sexual dysfunction. Laparoscopic AAA repair provides no onset of erectile or sexual dysfunction but a global improvement after surgery. Ejaculation troubles are frequent and persistent at 1 year. However, EVAR treatment, doesn't allow recovering of sexual function at 1 year. LEVEL OF EVIDENCE: 4.

Evaluation and comparison of basic gestures in ex vivo laparoscopic surgery using a robotic instrument and traditional laparoscopic instruments.

BACKGROUND: The robotic Dextérité Surgical™ arm (DEX) is an instrument used in laparoscopy that provides 6 degrees of freedom and 360 degrees of rotation with a needle holder and scissors. To evaluate the benefits this instrument offers, we asked novice surgeons to use DEX and a conventional laparoscopic instrument on a pelvitrainer and compared the results. METHODS: The participants were asked to perform two exercises with DEX and then with a conventional laparoscopic instrument on a pelvitrainer that contained a synthetic reproduction of a male pelvis. For the stitching exercise, the distance from the marked points and any tears caused were analyzed. For the cutting, the participants were judged by how well they respected the marked extremities, the form and the amount of "hacking" observed on a multi-criteria scale. The amount of time required to carry out the exercises was recorded. RESULTS: All twelve urology interns all succeeded in using DEX. Of the 36 stitches, seven were giving a failing grade (19.4%) when using the conventional laparoscopic needle holder and one (0.3%) was recorded when using DEX. All of the criteria (entry and exit points, tears and duration) for the results obtained were better when using DEX compared to the classic laparoscopic tool. This difference was statistically significant for horizontal stitches and tearing. Concerning the cuts made, the global score obtained, following a multi-criteria scale, favored the use of DEX for 10 out of 12 candidates (83.3%) with an average score of +2.6 (±2.1). No significant difference was recorded for the duration of each exercise. CONCLUSION: It does not take novice operators long to understand how to use DEX. It enables precise stitching and reduces tearing while improving the quality of cuts compared to conventional laparoscopic instruments, all without slowing the user down. LEVEL OF EVIDENCE: 4.

Integrating Bacterial Identification and Susceptibility Testing: A Simple and Rapid Approach to Reduce the Turnaround Time in the Management of Blood Cultures.

We evaluated a rapid bacterial identification (rID) and a rapid antimicrobial susceptibility testing by disk diffusion (rAST) from positive blood culture to overcome the limitations of the conventional methods and reduce the turnaround time in bloodstream infection diagnostics. The study included hemocultures flagged as positive by bacT/ALERT®, identification by MALDI-TOF MS, and rAST. The results were compared to identification and antimicrobial susceptibility testing (AST) results by current standard methods, after 24 h incubation. For rAST categorical agreement (CA), very major errors (VME), major errors (ME), and minor errors (mE) were calculated. A total of 524 bacterial samples isolated from blood cultures were obtained, including 246 Gram-negative (GN) and 278 Gram-positive (GP) aerobes. The overall concordance of rID was 88.6%, and it was highest among GN (96%). A total of 2196 and 1476 antimicrobial agent comparisons were obtained for GN and GP, respectively. Evaluation of rAST, CA, VME, ME, and mE disclosed 97.7, 0.7, 0.5, and 1.1% for GN and 98.0, 0.5, 0.7, and 0.8% for GP, respectively. Meropenem CA, VME, and ME were 98.3, 0.5, and 0.5%, respectively; mE was not observed. Oxacillin CA, ME, and mE were 97.4, 1.6, and 0.6%, respectively; VME was not observed. Overall, kappa scores of the results of the comparisons demonstrated the high agreement between rAST and the standard method. Identification and AST of aerobic bacteria from positive blood cultures after a short period of incubation on solid blood agar is a fast and reliable method that may improve the management of bloodstream infections.

[Renal Trauma]. / Traumatismes du rein.

INTRODUCTION: Renal traumas are common, observed in 10% of patients with abdominal trauma. Most renal traumas are blunt, resulting from a direct hit or from an abrupt deceleration. MATERIAL AND METHODS: We realized a synthesis of renal trauma management for nurses. RESULTS: Clinical presentation often encompasses gross hematuria and lumbar pain. The best diagnostic tool is computed tomography (CT) urogram. Based on CT urogram images, renal traumas are classified according to the American Association for the Surgery of Trauma (AAST) classification in five grades of increasing severity. The management is conservative in the vast majority of cases and has been largely simplified over the past few years, being now mostly based on observation. Radiological interventional and endoscopic procedures are used only in very selected cases and surgical exploration has become extremely rare. CONCLUSION: The prognosis has also considerably improved and renal trauma rarely result in death or loss of the kidney nowadays.

Long-term oncological outcomes of cystic renal cell carcinoma according to the Bosniak classification.

OBJECTIVES: To evaluate the prognostic role of the Bosniak classification on the long-term oncological outcomes of cystic renal cell carcinomas. MATERIAL AND METHOD: In a national multicentric retrospective study, we included patients treated surgically for localized cystic RCC from 2000 to 2010. Patients with a follow-up of less than 4 years, benign tumors, and ablative treatments were excluded. The primary outcome was disease-free survival. RESULTS: 152 patients met the inclusion criteria: Bosniak II (6%), III (53%), IV (41%), with a median follow-up of 61 (12-179) months. Characteristics of the population and the tumors were [median, (min-max)] age 57 (25-84) years old, tumor size 43 mm (20-280), RENAL score 7 (4-12), PADUA score 8 (5-14). Treatments were 55% partial nephrectomy, 45% radical nephrectomy, 74% open surgery, and 26% laparoscopy. In pathological report, cystic RCC were mainly of low grade (1-2, 77%) and low stage (pT1, 81%). The two main histological subtypes were conventional (56%) and papillary (23%) RCC. Staging at presentation and histological characteristics were similar between Bosniak III and IV, except for high grade which was more common in Bosniak IV (12 vs 36%, p < 0.01). The Bosniak classification was not predictive of the recurrence, as 5- and 10-year disease-free survival were similar in Bosniak III and IV (92% vs 92% and 84% vs 83%, p = 0.60). CONCLUSION: The Bosniak classification is predictive of the risk of malignancy but not of the oncological prognosis. Regardless of the initial Bosniak categories, almost all cystic RCCs were of low stage/grade and had low long-term recurrence rate.

Secondary bladder exstrophy repair with a bilateral gracilis muscle flap in an adult female patient: Case report of an original procedure.

Classical bladder exstrophy (CBE), affecting 1 birth out of 30,000, is characterized by an evaginated bladder plate through a defect in the lower abdominal wall, multiple abdominal wall anomalies including a pubic bone arch dehiscence. Numerous approaches from childhood to adulthood are thus required, depending on the severity of the deformity, including the associated genital anomalies. We report the case of a 19-year-old woman with CBE with a history of three-failed primary closure. We performed a secondary neck closure with a concomitant suspension of the bladder neck and reconstruction of the lower abdominal wall using a bilateral gracilis muscle flap transposition. The early postoperative course was uneventful. The patient was discharged at day ten postoperatively. The upper part of the genital sutures (labia minora) secondary healed in three weeks. Assessment at 2, 6 and 16 months postoperatively, respectively noticed a complete healing with successful sexual intercourses, perceived gracilis contraction by the patient, and finally, recent attempts to get pregnant. Neither urinary infection nor urinary leaks occurred. Bilateral crossed gracilis muscles transfer linking both rectus abdominis muscle in front of the reconstructed bladder neck might benefit to bladder exstrophy patients.
