RESUMO

Moderate stress increases memory and facilitates adaptation. In contrast, intense stress can induce pathological memories as observed in post-traumatic stress disorders (PTSD). A shift in the balance between the expression of tPA and PAI-1 proteins is responsible for this transition. In conditions of moderate stress, glucocorticoid hormones increase the expression of the tPA protein in the hippocampal brain region which by triggering the Erk1/2MAPK signaling cascade strengthens memory. When stress is particularly intense, very high levels of glucocorticoid hormones then increase the production of PAI-1 protein, which by blocking the activity of tPA induces PTSD-like memories. PAI-1 levels after trauma could be a predictive biomarker of the subsequent appearance of PTSD and pharmacological inhibition of PAI-1 activity a new therapeutic approach to this debilitating condition.

RESUMO

INTRODUCTION: The Acute Cystitis Symptom Score (ACSS) questionnaire first developed in Russian and Uzbek languages and now available in many other languages can be used for clinical diagnostics and patient-reported outcome (PRO) in female patients with acute uncomplicated cystitis (AUC). The aim of the current study was the linguistic validation and cognitive assessment of the French version of the ACSS questionnaire according to internationally accepted guidelines. METHODS: After two forward translations from Russian into the French language and backward translation into Russian and Uzbek, the two original languages, the scientific committee (SC) performed a slightly adapted French version, which finally was cognitively assessed by female subjects with different ages and educational levels and medical professionals, such as nurses, physicians, and pharmacists. RESULTS: All comments of the female subjects and professionals were discussed within the SC and after slight, but necessary adaptations, the SC agreed on the final study version of the French ACSS. CONCLUSION: Now, the linguistically validated and cognitively assessed French version of the ACSS can be used for clinical studies and practice.

RESUMO

BACKGROUNDS: Spermatic cord torsion is a frequent urological emergency that mostly concerns teenagers and young adults. This study aimed to determine the clinical and surgical characteristics of young adults who had scrotal exploration for suspected spermatic cord torsion and to identify clinical risk factors associated with needless scrotal exploration. METHODS: We retrospectively collected national data from patients aged 12years and older who underwent a surgical exploration for suspicion of torsion of the spermatic cord between 2005 and 2019 in 17 hospitals. We analyzed demographics, surgical and postoperative characteristics in our population. We compared the cohort according to the intraoperative diagnosis of torsion or not. RESULTS: In total, 2940 had surgical exploration: 1802 (61.3%) patients had torsion of the spermatic cord and 1138 (38.7%) had another diagnosis. In multivariate analysis, age (OR: 1.04; 95% CI: 1.01-1.06; P=0.005), medical history of cryptorchism (OR: 4.14; 95% CI: 1.05-16.31; P=0.042) and VAS pain score (OR: 0.91; 95% CI: 0.83-0.98; P=0.018) were risk factors significantly associated with unnecessary surgical exploration. The rate of complications in the 90days after surgery was 11% in the "torsion" group, and 9.7% in the "non-torsion" group (P=0.28). CONCLUSION: Scrotal exploration without intraoperative diagnosis of torsion was performed in 40% of our cohort. VAS pain score and cryptorchism history can help for the diagnosis but scrotal exploration remains the way to diagnose spermatic cord torsion and should be performed on the slightest suspicion, even after 24hours of symptoms, as the chances for testicular salvage remains around 50%.

RESUMO

INTRODUCTION: Biochemical recurrence of prostate cancer after radiation therapy occurs in 5 to 50% of cases depending on the radiation technique used. The diagnosis of recurrence of prostate adenocarcinoma must be made accurately. The aim of this study was to compare transperineal saturation and target biopsies to index lesion (IL) as defined on MRI and 18FCholine PET-CT (PETc) for detection of intra-prostatic recurrence after primary radiation therapy for prostate cancer. MATERIALS AND METHODS: Thirty-eight patients with an history of prostate radiation for prostate cancer and biochemical recurrence were retrospectively included between March 2013 and June 2017. All patients had PETc and multiparametric MRI (MRI) defining IL. All patients had transperineal saturation biopsies and target biopsies the IL. RESULTS: Among 38 patients with biochemical recurrence, 33 (87%) had biopsy proven recurrence in the prostate. The sensitivity and specificity of MRI were 32% (SD:19%) and 91% respectively (SD:7%). The sensitivity and specificity of PETc were 33% (SD:22%) and 78% respectively (SD:12%). Saturation trans-perineal and target biopsies allowed detection of disease recurrence in 79% and 84% of patients, respectively. CONCLUSION: In case of positive imaging, both trans-perineal prostate saturation and target biopsies offer good performance to confirm intraprostatic recurrence. However, MRI and PETc low sensitivity to detect all sites of local recurrence of prostate cancer after radiation still justify the completion of systematic saturation biopsies. LEVEL OF EVIDENCE: 3.

RESUMO

Prostate biopsy is sometimes complicated by infection which can lead to death. The risk factors remain controversial, notably the urine bacterial culture carried out before a prostate biopsy. The increase in resistance induces an increase in the number of complications and the need to define new antibiotic prophylaxis strategies. The urine bacterial culture remains widely discussed in cases with post-prostate biopsy infections and urologists or experts await clear recommendations on this subject. The Infectiology Committee of the French Association of Urology has therefore set up a literature analysis work in order to reach a consensus within the committee. METHOD: A literature search was performed on Pubmed and Medline. We selected randomized studies or meta-analyzes using the keywords "prostate biopsy" and "infection" or "infectious complications". All abstracts and articles have been analyzed. The summary of the analysis was reviewed by all the members of the committee proposing the most consensual recommendation possible. RESULTS: The literature on the subject remains poor, but no evidence of a link between prebiopsy bacteriuria and post-biopsy infection has been demonstrated. CONCLUSIONS: Apart from a clinical situation which could evoke a male urinary tract infection, and moreover having to prefer the postponement of biopsies, it is not recommended to perform a routine urine culture before endo-rectal prostate biopsies (expert opinion).

RESUMO

INTRODUCTION: No recent national guidelines exist regarding the management of urinary tract infections (UTIs) in the presence of ureteral stent. This situation could lead to discrepancies in clinical management and less opportunity for a favorable patient's outcome. METHODS: All available data published on Medline® between 1998 and 2018 were systematically searched and reviewed. All papers assessing adult patients carrying ureteral stent were included for analysis. After studies critical analysis, national guidelines for clinical management were elaborated in order to answer clinical questions. RESULTS: A total of 451 articles were identified, of which 58 have been included. The prevalence of urinary tract infections in the presence of ureteral stent remains unknown. After 3 months, all endo-ureteral devices were colonized on microbiological study. These patients also presented a positive urine culture in 25 to 70% of the cases, often polymicrobial. Staphylococci, E. coli, Klebsiella, Pseudomonas, Enterococcus and Candida were the commonest micro-organisms responsible for urinary colonization or infection. The risk of UTI on endo-ureteral devices seemed higher the longer it stayed implanted. There is no justification in the literature to recommend a systematic change of endo-ureteral devices following a urinary tract infection. DISCUSSION: The existing literature is rich but of poor methodological quality, and therefore does not allow to draw robust conclusions. The greatest difficulty faced in this work was to accurately differentiate urinary colonizations from true infections, including clinical symptoms and not only microbiological results. CONCLUSION: These guidelines propose a standardized management of such common clinical situations. Well-designed studies are needed to upgrade the level of evidence of these guidelines.

RESUMO

OBJECTIVE: A single immediate instillation of mitomycin C is recommended after a complete transurethral resection of the bladder (TURB) in low- and intermediate-risk patients with NMIBC. Actually, post-TURB instillation is seldom used due to logistical difficulties and surgical contraindications. Our aim was to compare patients with single pre-TURB intra-vesical instillation and patients with a single, immediate post-TURB intra-vesical instillation of mitomycin C. METHODS: We performed a multicenter randomized trial between February 17, 2014 and November 24, 2016 (registration number 2012-004341-32). Sixty patients with two or less, primary or recurrent papillary bladder tumors and a negative urinary cytology were planned. Cystoscopy was performed at 3, 6 and 12 months after TURB. Our primary endpoint was disease-free interval. Secondary endpoints were recurrence rate at 3 and 12 months, rate of patients in whom instillation could not be performed and tolerance 1 month after TURB using BCI-Fr score. RESULTS: Among 35 eligible participants, 20 were randomly assigned in the pre-TURB instillation group and 15 in the post-TURB instillation group. Follow-up was comparable: 12,3±1,6 months in the SI group and 10,2±4,5 months in the pre-TURB instillation group. In the post-TURB instillation group, 2 patients didn't have any instillation. We did not identify significant differences in disease-free interval. Tolerance at 1 month after TURB was similar in both groups. CONCLUSION: Tolerance and efficacy were not significantly different. As expected, logisitics were easier for the health providers in the pre-TURB group where all patients had their instillation conversely to the post-TURB group. These results suggest that the advantages of a single immediate pre-TURB instillation warrant further evaluation of this strategy in a phase III randomized trial.

RESUMO

OBJECTIVE: To report the nature, diagnosis and therapeutic strategy of infectious emergencies in urology. MATERIAL AND METHODS: Bibliographic research from Pubmed, Embase, and Google scholar in July 2021. A synthesis of the guidelines of national infectious diseases societies. RESULTS: Urosepsis and complicated urinary tract infection have a standardized definition. Diagnosis and therapeutic strategy are presented for upper tract urinary infection, male urinary infection, healthcare associated urinary infection, symptomatic canduria and urinary infections of the elderly. Appropriate antibiotherapy should be tailored to the degree of severity, bacterial ecosystem, patient characteristics et localization of the infection. CONCLUSION: Urinary infections can be critical and require immediate care. Knowledge of the guidelines and of appropriate diagnosis and therapeutics strategy improve care which should be rapidly applied, and collegial.

RESUMO

PURPOSE: The emergence of new communication media such as digital contents are progressively replacing more traditional medias in the field of educational programs. Our purpose was to assess urologist in training aspirations regarding urological education. METHODS: Members of a national urologist in training association were sent an anonymous online questionnaire regarding their medical formation in the field of urology. Responders interest for urological sub-specialty or education support (new tools and traditional support) were evaluated through a 5-point Likert scale. RESULTS: Overall, 109 young urologists (26%) responded to the survey. Most of the respondents worked during their training in an academic hospital (n=89, 82%). The three favorite tools for training chosen by the responders were: videos, workshop or masterclass, and podcasts (responders very interested were respectively n=64 (58.7%), n=50 (45.9%), and n=49 (45%)). E-mail newsletters were reported as the less useful educational tool by participants (n=38, 34.9%). Participants were very interested in improving their surgical skills and their radiological knowledge. Responders who were the most attracted by PCa were much more looking to improve their systemic treatment and radiological knowledges. CONCLUSIONS: Urologic-oncology was a priority regarding education for urologists in training. A majority of participants expressed a lack in their surgical education, revealing a reduced OR access and underlining utilization of new tools such as simulation. New digital contents such as social media or podcast achieved high interest for the participants, instead of more traditional media. There is a need that educational content evolve and uses new digital media. LEVEL OF EVIDENCE: 3.

RESUMO

INTRODUCTION: The objective was to evaluate, by self-questionnaire, the feeling of participants in surgical training sessions on a live porcine model. METHODS: A computerized questionnaire (GoogleForm ©) was sent to the members of the French Association of Urologists-in-Training (AFUF) (fellows and residents). Only questionnaires from Urologists-in-training who had participated in surgical training sessions were included. The sessions consisted of performing surgeries such as laparoscopic nephrectomies or laparoscopic cystectomies. RESULTS: Overall, 198 met the inclusion criteria. A total of 36.4% (72/198) of the participants were fellows and 63.6% (126/198) were residents. According to the participants, the main interest of sessions was to be able to train for emergency situations. A total of 79.8% (158/198) of the participants wanted surgical simulation to become compulsory. To their opinion, the main advantage of surgical simulation on a live porcine model was: technical progress in 87.4% (173/198) of cases. A total of 13.1% (26/198) of the participants found it was unethical to perform the first technical procedures on live animal models. A total of 65.7% (130/198) of the participants considered that there is currently no system of substitution. CONCLUSION: For the participants, surgical training on a live porcine model allows technical progress while training for serious emergency situations. Surgeons and patients could benefit from this risk-free mock surgical scenario. LEVEL OF EVIDENCE: 3.

RESUMO

BACKGROUND AND PURPOSE: Assessing patients' disability in multiple sclerosis (MS) requires time-consuming batteries of hospital tests. MSCopilot is a software medical device for the self-assessment of patients with MS (PwMS), combining four tests: walking, dexterity, cognition and low contrast vision. The objective was to validate MSCopilot versus the Multiple Sclerosis Functional Composite (MSFC). METHODS: This multicentre, open-label, randomized, controlled, crossover study enrolled 141 PwMS and 76 healthy controls (HCs). All participants performed MSCopilot and MSFC tests at day 0. To assess reproducibility, 46 PwMS performed the same tests at day 30 ± 3. The primary end-point was the validation of MSCopilot versus MSFC for the identification of PwMS against HCs, quantified using the area under the curve (AUC). The main secondary end-point was the correlation of MSCopilot z-scores with MSFC z-scores. RESULTS: In all, 116 PwMS and 69 HCs were analysed. The primary end-point was achieved: MSCopilot performance was non-inferior to that of MSFC (AUC 0.92 and 0.89 respectively; P = 0.3). MSCopilot and MSFC discriminated PwMS and HCs with 81% and 76% sensitivity and 82% and 88% specificity respectively. Digital and standard test scores were highly correlated (r = 0.81; P < 0.001). The test-retest study demonstrated the good reproducibility of MSCopilot. CONCLUSION: This study confirms the reliability of MSCopilot and its usability in clinical practice for the monitoring of MS-related disability.

RESUMO

INTRODUCTION: Acute urinary tract infections (UTIs) in adult are now a major public health issue in terms of morbidity, mortality and in terms of costs for society. The latest French guidelines and the European Association of Urology guidelines differ in some points. The aim of this article is to compare the guidelines of these two societies in order to highlight their differences but also their common points in the management of UTIs. METHODS: A comparative analysis of the latest French and European guidelines was carried out. The authors defined the following sub-sections: terminology, pyelonephritis, male UTIs, pregnancy urinary tract infections and cystitis. RESULTS AND CONCLUSION: The guidelines of these two societies are not very different in terms of diagnostic and therapeutic management. The major differences are in the duration of antibiotic therapies, where French guidelines continue to recommend long term treatments where EAU sometimes recommends only 5 days of antibiotics, as in the case of simple acute pyelonephritis.

RESUMO

INTRODUCTION: The COVID-19 outbreak in France is disturbing our health system. Urologists in training who are already known to have burnout, are in the front line to face this disease. The aim of our study was to assess the psychological impact of COVID-19 pandemic on young French urologists in training. MATERIAL AND METHODS: A self-administered anonymous questionnaire evaluating the pandemic added stress, and its negative impact on work and training quality, was e-mailed to the members of the French Association of Urologists in Training (AFUF). The association includes all French junior and senior residents. The survey lasted 3 days. Multivariable analyses using logistic regression was performed to identify the predictive factors. RESULTS: Two hundred and seventy-five (55.5%) of the 495 AFUF members responded to the questionnaire. More than 90% of responders felt more stressed by the pandemic. Fellows and senior residents were more likely to feel that the crisis had an important impact on their work quality (OR=1.76, IC95=[1.01-3.13]), even more when COVID 19 patients were present in their department (OR=2.31, IC95=[1.20-4.65]). Past medical history of respiratory disease (OR=2.57, IC95=[1.31-5.98]) and taking in charge COVID19 patients (OR=1.85, IC95=[0.98-3.59]) were additional risk factors. CONCLUSION: COVID19 pandemic has a negative impact on young French urologists in training and on their work and training quality. Managing their psychosocial well-being during this time is as important as managing their physical health. LEVEL OF EVIDENCE: 3.

RESUMO

INTRODUCTION: The aim was to assess the risk of postoperative infections in patients with preoperative polymicrobial urine culture and to provide the urologist with practices to minimise the risk of infection in these clinical situations. METHODS: A systematic literature review was carried. All national and international recommendations have been reviewed. Data collection has been performed from the Cochrane, LILACS and the Medline database. 31 publications were selected for inclusion. RESULTS: Risk of infection in patients without ureteral stents or urinary catheters with previous polymicrobial urine culture is low. In the absence of leukocyturia, the urine sample can be considered as sterile. With ureteral stents or urinary catheters, the colonisation by biofilm ranges from 4 to 100% depending on the duration and ureteral stents or urinary catheters type. Urine culture is positive 24 to 45% of the time when ureteral stents or urinary catheters are known to be colonised. The post-operative risk of infection in endo-urological surgery in a patient with ureteral stents or urinary catheters is estimated around 8 to 11% depending on the type of surgery. A retrospective study reports a postoperative infections rate of 18.5% in photo selective vaporization of the prostate with preoperative polymicrobial urine culture. CONCLUSIONS: Scientific data are limited but for patients without ureteral stents or urinary catheters, in the absence of leukocyturia, the polymicrobial urine culture can be considered as negative. Considering a preoperative polymicrobial urine culture as sterile in patients with colonised ureteral stents or urinary catheters is at risk of neglecting a high risk of postoperative infections or sepsis even in case of perioperative antibiotic prophylaxis. It should not always be considered sterile and therefore, a perioperative antibiotic therapy could be an acceptable option.

RESUMO

Cannabis-induced acute psychotic-like states (CIAPS) represent a growing health issue, but their underlying neurobiological mechanisms are poorly understood. The use of antipsychotics and benzodiazepines against CIAPS is limited by side effects and/or by their ability to tackle only certain aspects of psychosis. Thus, safer wide-spectrum treatments are currently needed. Although the blockade of cannabinoid type-1 receptor (CB1) had been suggested as a therapeutical means against CIAPS, the use of orthosteric CB1 receptor full antagonists is strongly limited by undesired side effects and low efficacy. The neurosteroid pregnenolone has been recently shown to act as a potent endogenous allosteric signal-specific inhibitor of CB1 receptors. Thus, we tested in mice the potential therapeutic use of pregnenolone against acute psychotic-like effects of Δ9-tetrahydrocannabinol (THC), the main psychoactive component of cannabis. We found that pregnenolone blocks a wide spectrum of THC-induced endophenotypes typically associated with psychotic-like states, including impairments in cognitive functions, somatosensory gating and social interaction. In order to capture THC-induced positive psychotic-like symptoms (e.g. perceptual delusions), we adapted a behavioral paradigm based on associations between different sensory modalities and selective devaluation, allowing the measurement of mental sensory representations in mice. Acting at hippocampal CB1 receptors, THC impaired the correct processing of mental sensory representations (reality testing) in an antipsychotic- and pregnenolone-sensitive manner. Overall, this work reveals that signal-specific inhibitors mimicking pregnenolone effects can be considered as promising new therapeutic tools to treat CIAPS.

RESUMO

INTRODUCTION: The incidence of surgical site infections (SSI) in urological surgery is highly variable. The latest report of the "Institut de veille sanitaire" (InVS) found an incidence of SSI of 3% but in some specific clinical situations, rates close to 20% are sometimes observed. The aim of this publication is to provide urology nurses with a summary of the management of the main postoperative infections that can be encountered in urological surgery. MATERIAL AND METHOD: The main infectious pathologies likely to be encountered after urology have been classified in 4 chapters by repeating the formulations used by InVS by adding the specificities related to urological surgery. The management of the pathologies described is based on current French and European guidelines. RESULTS: The importance for urology nurses to know how to recognize a potentially lethal SSI is here to remind, especially with the need to master the use of the "quick SOFA" score. The SSI in urology were then grouped as follows: postoperative urinary tract infection, superficial wound infection, deep wound infection, organ infection and material's infection. CONCLUSION: While urinary tract infections are potentially the most serious and sometimes fatal, superficial or deep infections can be a source of prolonged hospitalization with repercussions on postoperative rehabilitation of patients. Nurses must therefore be fully trained to recognize them because they are often in the front line in case of occurrence of a SSI.

RESUMO

INTRODUCTION: In France, the urinary catheterization especially in men, is governed by Article R. 4311-10 of Decree No. 2004-802 of 29 July 2004 of the Public Health Code. Although this gesture is framed by law, there is currently no French guidelines formalized on a single and easily accessible support for the technique and management of the urinary catheterization. The aim of this study was to provide a simple reference about technical aspects and management of urinary catheterization in men. MATERIALS AND METHODS: The European recommendations on urinary catheterization were updated and adapted with additional arguments in certain situations to cover all aspects of urinary catheterization. This work was conducted to improve the nurses knowledge about this topic. RESULTS: We give here a reproducible technique in order to limit complications related to the most frequent invasive gesture in urology. We also propose a scheme to harmonize the management of indwelling urinary catheterization. CONCLUSION: This work gives to nurses a practical document in order to standardize and to secure a gesture governed by dogmas since too long. The drafting of guidelines and the creation of educational tools for medical and para-medical personnel would probably improve practices in this topic. LEVEL OF EVIDENCE: 4.

RESUMO

BACKGROUND: Moderate-risk genes have not been extensively studied, and missense substitutions in them are generally returned to patients as variants of uncertain significance lacking clearly defined risk estimates. The fraction of early-onset breast cancer cases carrying moderate-risk genotypes and quantitative methods for flagging variants for further analysis have not been established. METHODS: We evaluated rare missense substitutions identified from a mutation screen of ATM, CHEK2, MRE11A, RAD50, NBN, RAD51, RINT1, XRCC2 and BARD1 in 1297 cases of early-onset breast cancer and 1121 controls via scores from Align-Grantham Variation Grantham Deviation (GVGD), combined annotation dependent depletion (CADD), multivariate analysis of protein polymorphism (MAPP) and PolyPhen-2. We also evaluated subjects by polygenotype from 18 breast cancer risk SNPs. From these analyses, we estimated the fraction of cases and controls that reach a breast cancer OR≥2.5 threshold. RESULTS: Analysis of mutation screening data from the nine genes revealed that 7.5% of cases and 2.4% of controls were carriers of at least one rare variant with an average OR≥2.5. 2.1% of cases and 1.2% of controls had a polygenotype with an average OR≥2.5. CONCLUSIONS: Among early-onset breast cancer cases, 9.6% had a genotype associated with an increased risk sufficient to affect clinical management recommendations. Over two-thirds of variants conferring this level of risk were rare missense substitutions in moderate-risk genes. Placement in the estimated OR≥2.5 group by at least two of these missense analysis programs should be used to prioritise variants for further study. Panel testing often creates more heat than light; quantitative approaches to variant prioritisation and classification may facilitate more efficient clinical classification of variants.

RESUMO

INTRODUCTION: Temocillin is an alternative to treat urinary tract infections with bacteria producing extended spectrum beta-lactamase (ESBL). The objective is to evaluate the use of temocillin in urinary tract infections. MATERIALS AND METHODS: A systematic review of literature was carried out according to PRISMA criteria. All national and international recommendations have been reviewed regarding the indication of the use of temocillin in urology. Data collection on the use of temocillin in urinary tract infection has been performed from the Cochrane, LILACS and the Medline database. The following keywords were used: temocillin, extended spectrum beta-lactamase, urinary tract infections, urine, prostate, epididymis, testis, diffusion, pharmacokinetics, pharmacodynamics. The selection was based on the methodology, language of publication (English/French), relevance to the topic and date of publication of the articles collected. The endpoint was to provide exhaustive scientific information allowing urologists to use this antibiotic in febrile urinary infections. RESULTS: Bacteria producing ESBL has a relatively high susceptible to temocillin, ranging from 61 % to 90 %. These rates would allow its use in probabilistic. The dosage recommended is currently, in the normo-renal patient, 4g per day by intermittent infusion or continuously after a loading dose of 2g. Some studies argue, particularly in case of difficult clinical situations or obese patients, for administration of high doses (6g/24h) rather continuous infusion. There is no evident relationship between high doses and side effects. With an excellent urinary and prostatic diffusion, temocilllin might be recommend for the treatment of ESBL prostatitis. CONCLUSION: Temocillin is known to have good urinary and prostatic diffusion. According to our results, this antibiotics is now a reliable alternative for the treatment of documented ESBL urinary tract infections. LEVEL OF EVIDENCE: 4.

RESUMO

INTRODUCTION: The lengthening of life expectancy associated with multiple comorbidities leads physicians and nurses to manage more and more patients with long-term urinary catheterization (LTUC). No recommendation is written about the management of LTUC patients. To assess the need to publish recommendations and tools to help nurses in a better management of LTUC, we conducted a survey of theoretical and practical knowledge of French nurses. MATERIALS AND METHODS: Epidemiological prospective study, type of practical studies in a declarative fashion, anonymous, made via computerized poll released on the website www.infirmiers.com. RESULTS: A total of 1254 registered nurses fulfilled the questionnaire. We observed a massive heterogeneity in different aspects of LTUC: local care and products used in them, urine bag change rhythm, lubrication of the catheter, respect of closed system, the rhythm of catheter change and in the management of blocked catheters. In total, 76% of nurses desire a theoretical and practical help for LTUC. CONCLUSION: We found a great diversity of knowledge and practices in terms of LTUC. In total, 40.67% of nurses realized at least a technical error during catheterization. To standardize the management of LTUC, we propose to draft recommendations under the aegis of the French Association of Urology. This will allow a better education of students, and providing online available support.
