A network of HF receivers intended for multi-position monitoring of the ionosphere is described. At present, it includes nine observation sites located at high, middle and low latitudes in both hemispheres of the Earth. The basic element of the network is a small-size receiving and measuring units designed at the Institute of Radio Astronomy (IRA) of the National Academy of Sciences of Ukraine (NASU) on the basis of a personal computer equipped with commercial digital receiving modules. Software packages developed by the authors make it possible to remotely control the facilities via the Internet network. The received emissions are HF signals from special transmitters and broadcast radio stations. These are processed using Doppler and pulse selection algorithms. In the Internet-controlled mode, the observation results are transferred to the main server in real time to be automatically processed and visualized at the website of the IRA NASU’s Department of Radiophysics of Geospace. Several examples of using the observation results obtained with the HF receiver network for diagnostics of dynamic processes in the near-Earth plasma are presented. The advantages of the multiposition mode of observations are discussed. The possibility of upgrading the HF facilities to provide measuring angles of arrival of signals is considered.

- Abstract
The objective of this study was to propose a French version of the satisfaction survey for inflatable penile implant (SSIPI) questionnaire.Questionnaire validation was performed in three steps: translation into French by two urologists, its validation by the committee of andrologist and sexual medicine (CAMS) and an independent translation in English by another urologist to exclude any distortion with the original version. Furthermore, the questionnaire was tested in few patients having penile implant.The andrology committee approved the French version of the questionnaire. The final version of the questionnaire was successfully tested on all patients. Every patient (n=10) confirmed the good comprehension and pertinence of the questions, and the easy response selection.This French version of the SSIPI questionnaire will allow French-speaking urologists to assess the satisfaction of their patients with a penile implant on a large scale.IV.

IntroductionPeyronie's disease is a common cause for consultation in urology. Many controversies surround its treatment. No French Guidelines have been published so far. The Committee of Andrology and Sexual Medicine of the French Association of Urology therefore offers a series of evidence-based recommendations.Materials and methodsThese recommendations are made according to the ADAPTE method, based on European (EAU, ESSM), American (AUA, ISSM) and Canadian (CAU) recommendations, integrating French specificities due to the availability of treatments, and an update of the recent bibliography.ResultsThe assessment of the disease is clinical. Patients with functional impairment or significant psychological repercussions may be offered treatment. The benefits and drawbacks of each treatment should be explained to the patient. Regarding non-surgical treatments, no available treatment has market authorization in France. Vitamin E is not recommended. Analgesic (oral or low-intensity shock waves) or proerectile treatments may be offered as needed, as well as traction therapy. Due to the unavailability of collagenase injections, verapamil injections may be offered. Surgical treatments are to be considered in the stabilized phase of the disease, and consist of performing a plication, an incision-graft or the placement of a penile implant according to the patient's wishes, the curvature and the penis size, as well as erectile function. Combination treatments can be offered.ConclusionThe management of Peyronie's disease is complex, and the levels of evidence for treatments are generally low. The success of treatment will depend on the quality of the initial assessment, the patient's information and understanding of the expected effects, and the practitioner's experience., IntroductionLa maladie de Lapeyronie est un motif fréquent de consultation en urologie, dont le traitement reste sujet à de nombreuses controverses. Elle n’a fait l’objet d’aucune recommandation française jusqu’à présent. Le Comité d’Andrologie et de Médecine Sexuelle de l’Association Française d’Urologie propose donc une série de recommandations basées sur les preuves.Matériels et méthodesCes recommandations sont réalisées selon la méthode ADAPTE, en se basant sur les recommandations européennes (EAU, ESSM), américaines (AUA, ISSM) et canadiennes (CAU), en intégrant les spécificités françaises en raison de la disponibilité des traitements, et une mise à jour de la bibliographie récente.RésultatsL’évaluation de la maladie est clinique. Les patients présentant une gêne fonctionnelle ou un retentissement psychologique important peuvent se voir proposer un traitement. Les bénéfices et inconvénients de chaque traitement devront être explicités au patient. Concernant les traitements non chirurgicaux, aucun traitement disponible n’a l’autorisation de mise sur le marché en France. La vitamine E n’est pas recommandée. Des traitements à visée antalgiques (oraux ou ondes de choc de faible intensité) ou pro-érectiles peuvent être proposée selon le besoin, ainsi qu’une thérapie par traction. En raison de l’indisponibilité des injections de collagénase, les injections de vérapamil peuvent être proposées. Les traitements chirurgicaux sont à considérer en phase stabilisée de la maladie, et consistent en la réalisation d’une plicature, d’une incision-greffe ou de la pose d’un implant pénien en fonction du souhait du patient, de la courbure et de la taille de verge, ainsi que de la fonction érectile. Des traitements combinés peuvent être proposés.ConclusionLa prise en charge de la maladie de Lapeyronie est complexe, et les niveaux de preuve des traitements sont faibles dans l’ensemble. Le succès du traitement dépendra de la qualité de l’évaluation initiale, de l’information du patient et de sa compréhension des effets attendus, et de l’expérience du praticien.

Objectifs La vasectomie selon la technique « sans bistouri » est consideree comme etant la technique de reference par plusieurs associations savantes. Avec l’augmentation du nombre de demandes, l’objectif de la publication a ete d’analyser les complications precoces et tardives de notre serie de vasectomies realisees selon cette technique. Methodes Une etude retrospective a ete realisee aupres de 380 patients qui ont beneficie d’une vasectomie selon la technique « sans bistouri » entre janvier 2016 et mai 2021. L’alimentation de la base de donnees a ete realisee en temps reel par des questionnaires et des auto-questionnaires. Toutes les complications tardives ont fait l’objet d’une reunion de morbidite. L’etude statistique de base a ete realisee sur une base de donnees obtenue par requete a partir du dossier patient et l’analyse a l’aide de SPSS IBM. Resultats L’âge moyen des patients etait de 41,9 ans (21 a 62 ans). Il y a eu 234 procedures sous anesthesie locale (62 %), 104 procedures sous anesthesie locale avec une sedation vigile (27 %) et 42 sous anesthesie generale (11 %). La duree moyenne a ete de 17,8 minutes (± 8 minutes). En peroperatoire l’EVA a ete de 1,28 (± 1,26). Dans 314 interventions, il y eut un abord unique (82,6 %). Les complications ont ete 1 infection sur le clip accroche au Dartos, 3 hematomes, 1 epididymite, 1 douleur en erection, un regret (qui a necessite une vaso-vasostomie). Il y a eu 4 patients (1,05 %) avec des douleurs scrotales chroniques. Il a ete enregistre une grossesse 1 an apres malgre l’azoospermie confirmee a deux reprises et une repermeabilisation du deferent ( Tableau 1 ). Conclusion La vasectomie sans bistouri est rapide, sure et efficace. Elle necessite de maitriser la technique, un plateau technique adapte et une pratique reguliere. Les complications sont rares, et a part des douleurs scrotales chroniques, il n’y a pas de complication majeure. L’information preoperatoire est importante pour eviter les regrets et s’assurer de l’adhesion des patients jusqu’au controle du spermogramme.

Male ,Varicocele ,Humans - Abstract
The diagnosis of varicocele is clinical, carried out in supine and standing position and in Valsalva maneuver. Only clinical varicoceles have to be treated. A scrotal ultrasound with Doppler is generally performed as part of the infertile man's evaluation or in case of examination difficulties. The main indication for varicocele treatment is the adult man with clinical varicocele and abnormalities of sperm parameters, in a context of infertility of couple, with a partner having a satisfactory ovarian reserve and no cause of female infertility or a curable infertility cause. The decision to treat varicocele must therefore be taken after evaluation of the two partners of the couple. Adults with symptomatic varicocele and those with spermogram abnormalities may also be offered a cure for their varicocele even in the absence of a paternity plan, as well as adolescents with reduced testicular growth, an ipsilateral decrease testicular volume, or a size gradient between the 2 testes. The cure of varicocele can be carried out by surgery or by percutaneous embolization. Microsurgery (inguinal or subinguinal) offers lower rates of recurrence and complications than high surgical approaches (laparoscopic or not) and surgeries without magnification. It is therefore the reference surgical technique. Percutaneous retrograde embolization is a minimally invasive alternative to microsurgery offering satisfactory outcomes with rare and often benign complications. The cure for varicocele results in an improvement in sperm parameters and recent data seem to confirm that it increases the natural pregnancy rate. These results appear after a delay of 3 to 9 months (at least 1 to 2 cycles of spermatogenesis). When the sperm involvement was severe (azoospermia, severe oligospermia), the improvement of the spermogram allow (1) to avoid surgery testicular sperm extraction or (2) perform intrauterine insemination rather than ICSI.

Resume Contexte La maladie de Lapeyronie (ML) est une maladie inflammatoire de la verge, qui entraine la formation de plaques fibreuses cicatricielles de l’albugine avec une courbure et un raccourcissement du penis lors des erections. Il n’existe pas de standard international pour l’evaluation, le suivi ou le traitement de cette pathologie. Nous presentons dans cet article une revue de la litterature concentree sur les strategies therapeutiques decrites. Un algorithme est suggere pour faciliter l’evaluation et la prise en charge des patients. Materiels et methode La revue de la litterature a ete realisee selon la strategie PRISMA en utilisant la base de donnees PubMed et les termes Mesh : « Peyronie », « disease », « treatment » et « diagnosis ». Les resultats sont presentes d’une maniere descriptive. Resultats Plusieurs traitements ont ete proposes sans etudes randomisees prospectives englobant assez de patients. L’efficacite des therapies par voie orale est superieure dans le cadre d’une prise en charge multimodale de la phase aigue de la maladie. Les anti-inflammatoires non steroidiens et le para-aminobenzoate de potassium sont superieurs aux autres molecules pour le controle de la douleur. Le traitement local par verapamil gel, l’iontophorese et les injections intra-lesionnelles de verapamil, d’interferon alfa-2b et de collagenase clostridium histolyticum (CCH) ont revolutionne le traitement de la ML en modifiant la taille de la plaque et l’angulation du penis. Les therapies alternatives par traction ou par ondes de choc extracorporelles paraissent prometteuses. La CCH intra-lesionnelle est le seul medicament approuve par l’agence americaine des produits alimentaires et medicamenteux (FDA). Le tunellage de la plaque avant les injections de CCH ameliore davantage l’angulation. Conclusion Il existe une myriade de therapeutiques non chirurgicales disponibles pour la prise en charge de la ML, mais les preuves scientifiques de leur utilisation sont faibles. Des etudes supplementaires a grande echelle sont necessaires pour evaluer les pratiques actuelles, et concevoir des traitements plus efficaces.

OBJECTIVE: To assist urologists in the management of andrological and sexual medicine pathologies during the COVID-19 crisis. MATERIAL AND METHOD: Use of the formalized consensus method. RESULTS: The medical and surgical management of patients in andrology and sexual medicine must be adapted. Consultations should, as far as possible, be carried out by tele-consultation. For operative procedures, the delay between the operative decision and the date of (re)scheduling of the procedure will depend on: (1) the level of criticality of the clinical situation; (2) the type of intervention; (3) the functional and psychological repercussions, including quality of life while waiting for the procedure; (4) the notion of losing the chance of having an optimal outcome; (5) the risk of potential complications from delaying a procedure for too long; and (6) taking into account the patient's risk factors for severe forms of COVID-19. The protection of urologists from COVID-19 should be considered. Each urologist must make the best decision for the patient, taking into account the acceptable time frame and quality of life impact before surgical management, the COVID risk parameters, the technical and anesthetic feasibility and the structural possibility of the health care institution to ensure a specific dedicated pathway during the COVID-19 health crisis. CONCLUSION: The management of andrological and sexual medicine pathologies must be adapted to the COVID-19 crisis context. Some patients may require surgery, including in emergency. These recommendations are transitional and will end with the COVID-19 crisis.

Male ,Penile Induration ,Humans ,Algorithms - Abstract
Peyronie's disease is an inflammatory disorder of the penis, where scar tissue creates a plaque at the level of the albuginea, limits its extension, and leads to a bent and shorter penis during erections. There are no international standards for the evaluation and the treatment of the disease. The aim of this article is to review the current knowledge about the management of Peyronie's disease and to suggest an algorithm to help physicians evaluate and manage this condition.A literature review was conducted through PubMed database following PRISMA guidelines using the Mesh terms: Peyronie, disease, treatment and diagnosis. Results are presented in a descriptive manner.Multiple treatment strategies have been proposed, but no conclusive randomized clinical trial is done to assess their efficacies. The oral treatment was shown to be more beneficial in the setting of a multi-modal approach to treat the acute phase. The non-steroidal anti-inflammatories and the potassium para-aminobenzoate are superior to the other molecules of oral therapy for pain management. Local treatment with topical verapamil, iontophoresis and intra-lesional injection of verapamil, interferon alfa-2b and collagenase clostridium histolyticum (CCH) revolutionized the management of the disease by the modification of the plaque size and angulation. Alternative treatments using extra-corporeal shock wave or traction devices are promising. Intra-lesional injection of CCH is the only therapy approved by the Food and Drug Administration for this condition after the stabilization of the disease. The channeling of the plaque before CCH injections is making better results than the initial protocol, concerning angulation improvement.Multiple therapeutic strategies exist for the management of the Peyronie's disease, but they lack evidence based data. Further randomized clinical trials are needed to evaluate the current practices and to study more efficient treatments.

Objectifs La majorite des implants peniens sont mis en place au cours d’une hospitalisation conventionnelle en France ce qui contraste avec la tendance actuelle visant a augmenter le nombre d’actes realises en ambulatoire. L’objectif de ce travail est de montrer la faisabilite de cette chirurgie en ambulatoire. Methodes Une etude retrospective monocentrique a analyse les resultats postoperatoires precoces (jusqu’a activation realisee a 6 semaines) de patients programmes en chirurgie ambulatoire pour la mise en place d’un implant penien (primo-implantation ou revision) entre mars 2017 et fevrier 2018. Resultats Dix patients ont ete programmes en ambulatoire. L’âge median des patients etait de 69 ans (56–75). Six primo-implantations (5 implants hydrauliques et 1 semi-rigide) et quatre changements d’implants hydrauliques ont ete realises dans un contexte de dysfonction erectile postprostatectomie ( n = 5), vasculogenique ( n = 4) et consecutive a une maladie de la peyronie ( n = 1). L’approche chirurgicale etait peno-scrotale. Sept cas ont ete realises sous anesthesie generale et trois anesthesies locoregionales. Deux patients etaient sous antiagreants plaquettaires. Neuf patients ont pu rentrer a domicile le jour meme apres retrait du redon sous antibioprophylaxie et antalgiques de paliers I et II. Un patient ayant necessite une contre-incision abdominale pour la mise en place du reservoir a ete hospitalise une nuit pour surveillance. Aucune complication n’a ete rapportee au cours du suivi. Conclusion La mise en place d’un implant penien en chirurgie ambulatoire apparait comme une technique sure et efficace a envisager chez tous les patients candidats a cette chirurgie. Un suivi postoperatoire standardise est necessaire afin de garantir ces resultats.

Resume But Effectuer une revue de la litterature concernant le traitement de l’incontinence urinaire d’effort (IUE) de la femme d’origine non neurologique par les mini-bandelettes sous-urethrales. Methodes Revue de la base de donnees Medline/Pubmed jusqu’en juin 2013. La bandelette TVT-Secur™ a ete exclue, car ce dispositif n’est plus commercialise. Resultats Les deux dispositifs les plus etudies, hors TVT-Secur™, etaient Ajust™ et Mini-Arc™. Le Mini-Arc™ presentait des taux de succes entre 44 % et 91,4 % a un an. La bandelette Ajust™ etait le dispositif dont les resultats etaient les plus homogenes avec une efficacite a moyen terme d’environ 80 %. Un faible taux de complications per- et postoperatoires a ete rapporte dans tous les cas. Deux etudes randomisees ont ete publiees comparant mini-bandelette et bandelette traditionnelle avec un recul minimum de un an, ainsi qu’une meta-analyse. Ces differents travaux objectivaient des taux d’efficacite egaux ou inferieurs aux BSU traditionnelles. Conclusion Devant le faible recul, le niveau de preuve limite et l’heterogeneite des donnees publiees, les mini-bandelettes doivent etre evaluees dans le cadre de protocoles de recherche clinique.

Background Radiotherapy of prostate cancers, over the last few years, has been an alternative choice to radical prostatectomy in the case of localised cancers as well as being the preferred treatment in both advanced localised cancers and those of the elderly. A conventional course of prostate radiotherapy consisting of four to five sessions a week, lasts between 7 and 8 weeks plus about one week of preparation. Materials and methods A systematic review of the scientific literature based on Pubmed, along with an exhaustive review of randomised studies presented at international congresses, have made it possible to analyse the numerous therapeutic regimens available other than the conventional normofractioned one (i.e. with doses per session ranging between 1.8 and 2.2 grays). Results Five randomised trials reported since 2005, plus several thousand patients treated by stereotaxic radiotherapy, have given rise to numerous scientific questions; these alternative hypofractioned courses (dose per fraction higher than 2.2 grays) have a potentially enhanced antitumoral efficacity along with the practical advantages of a shortened duration of radiotherapy. Conclusion The aim of this analysis of the scientific literature on hypofractioning in prostate cancer radiotherapy is to gather all the scientific evidence we currently have at our disposal. Further mature results of future randomised trials will have to be examined before modifying current practice.

Objectifs Evaluer de facon prospective la prise en charge de la prostatectomie radicale cœlioscopique robot-assistee (PRR) en unite de chirurgie ambulatoire (UCA) pendant 1 an. Methodes Entre le 15/3/16 et le 31/5/17, 96 PRR ont ete realisees par le meme binome chirurgien-anesthesiste. Trente-quatre PRR ont ete programmees en UCA, apres avoir donne aux patients une information conforme aux recommandations de la HAS. Les interventions ont ete realisees suivant un protocole anesthesiste per- et postoperatoire specifique permettant la recuperation rapide apres chirurgie (RRAC). Les criteres de sortie etaient : EVA Resultats Toutes les PRR ont ete realisees en cœlioscopie transperitoneale, avec ou sans curage ilio-obturateur, avec ou sans preservation des bandelettes neurovasculaires. Trente et un des 34 patients programmes en UCA ont pu sortir le soir meme, donc moins de 12 h apres l’entree. Un patient sur les 31 sortis a du etre readmis en urgence le soir meme du fait d’une hematurie caillotante avec obstruction de la sonde vesicale. La sonde a simplement ete debouchee en chambre, et le patient est ressorti le lendemain, sans autre consequence. Deux patients n’ont pas pu sortir : l’un car son accompagnant pour la sortie et la nuit a eu un empechement, l’autre pour des raisons administratives de prise en charge. Tous les patients appeles le lendemain etaient satisfaits d’avoir pu passer la nuit a leur domicile. Tous les patients ont ete revus au 6e jour postoperatoire pour ablation de sonde vesicale. Conclusion La PRR peut etre proposee en UCA, sans en augmenter le risque de complications. Il s’agit d’un avantage specifique de la robotique, car aucune experience ambulatoire pour la prostatectomie n’avait ete tentee auparavant avec les autres abords chirurgicaux. La prise en charge en UCA diminue le stress lie a l’hospitalisation en permettant un retour rapide au domicile (

Resume But L’incontinence urinaire (IU) et la dysfonction erectile (DE) sont deux complications majeures de la prostatectomie totale (PT). Apres echec du traitement medical, la bandelette Advance™ et la prothese penienne sont des options therapeutiques validees. Notre but etait d’evaluer la faisabilite et les resultats de la combinaison de ces deux dispositifs. Patients Quatre patients ont ete traites pour IU et DE apres PT, par bandelette sous-uretrale et prothese penienne. Les criteres suivants etaient evalues en preoperatoire : âge, antecedents, score ASA, fibroscopie vesicale, pad-test, et bilan urodynamique. Deux patients ont recu les deux dispositifs en deux temps : la bandelette sous-uretrale puis la prothese penienne pour un, et la prothese penienne puis la bandelette sous-uretrale pour l’autre. Les deux autres patients ont ete traites en un temps : un a recu les deux dispositifs, et l’autre la bandelette sous-uretrale associee au remplacement d’une prothese penienne. Le suivi postoperatoire evaluait l’efficacite (nombre de protections par jour et echelle Patient Global Impression of Improvement [PGI-I] pour l’incontinence et la sexualite) et les complications. Resultats Il n’y a pas eu de complications peroperatoires. Apres un suivi minimum de 14 mois, les quatre patients ne portaient plus de protection. Le score PGI-I mettait en evidence un niveau de satisfaction optimal pour les quatre patients tant sur le plan urinaire que sexuel (score egal a 1). Conclusion Dans notre experience, la chirurgie combinee par bandelette transobturatrice Advance™ et prothese penienne etait possible, successivement ou simultanement, et menait a d’excellents resultats fonctionnels sans complications.

Resume La prostatectomie totale est le traitement de reference du cancer de prostate localise. La dysfonction erectile (DE) postoperatoire est un probleme important puisqu’elle peut concerner jusqu’a 80 % des patients operes dans certaines series. La selection des patients et la technique chirurgicale utilisee (preservation ou non des bandelettes vasculonerveuses) sont les facteurs les plus determinants pour l’apparition d’une DE postoperatoire. L’utilisation de traitements pharmacologiques, que ce soit par voie orale ou locale, s’avere efficace et sans effets secondaires importants. La plupart des hommes necessitent un traitement adjuvant pour redevenir sexuellement actif apres prostatectomie totale. Ces traitements comprennent les injections intracaverneuses, les vacuums et les gels intra-uretraux qui permettent d’obtenir un taux de reponse de 50 a 70 %. Neanmoins, la compliance au long cours est souvent decevante avec un taux d’interruption du traitement de l’ordre de 50 % a un an. Les traitements de la DE doivent etre envisages dans la phase postoperatoire precoce pour accroitre l’oxygenation des tissus peniens et prevenir la fibrose des corps caverneux. La reeducation erectile precoce avec des injections intracaverneuses doit etre proposee systematiquement chez les patients qui n’ont pas eu de preservation des bandelettes ou qui ont plus de 65 ans. Chez les patients qui ont eu une preservation des bandelettes vasculonerveuses, le traitement oral par IPDE5 en premiere ligne peut s’averer suffisant pour la reeducation pharmacologique et la recuperation optimale des erections. L’utilisation de traitement oral « a la demande » pour le traitement de la DE a demontre son efficacite notamment dans les cas selectionnes de patients jeunes qui ont eu une prostatectomie avec preservation nerveuse bilaterale realisee par des urologues experimentes.

Peyronie's disease (PD) is due to a fibrotic plaque forms in the tunica albuginea layer of the penis. It is responsible of penile pain, angulation, and erectile dysfunction. Even though the aetiology remains unknown, the knowledge of the pathophysiology has evolved in recent years. Recent studies indicate that PD has prevalence of 3 to 9% in adult men. During the initial acute phase (6 to 18 months), the condition may progress, stabilize or regress in 20%. Therefore, a conservative treatment approach has been advocated. An initial discussion about evaluation, information, and reassurance is necessary in most cases. The most commonly employed oral therapies include tocopherol (vitamin E), and para-aminobenzoate (Potaba), which have failed to demonstrate efficiency. Intralesional injection therapies with interferon alpha-2B, verapamil are frequently used as a first-line treatment modality, and can provide an improvement in decreasing penile pain and penile curvature. Current literature has shown that extracorporeal shock wave lithotripsy was only active on the pain. Regarding penile curvature, there are discrepancies in the published series. The surgical approach is restricted to men unresponsive to nonoperative therapies (i.e., 10% of patients). In such cases, plication, grafting or even penile prosthesis implantation are conceivable management options.

Resume Objectifs Evaluer l’interet porte a l’andrologie au sein de la communaute des urologues en formation. Materiel et methodes Entre juin et octobre 2008, l’ensemble des internes et chefs de cliniques en urologie ont recu un questionnaire anonyme par courriel evaluant leur interet pour l’andrologie. Les elements suivants ont ete releves : âge, sexe, statut actuel, mode d’exercice envisage, participation eventuelle aux enseignements theoriques et stages pratiques, interet pour la specialite et opinion sur la formation actuelle. L’analyse statistique a ete realisee grâce au logiciel SEM. Resultats Au total, 77 des 238 urologues en formation interroges (32,4 %) ont repondu au questionnaire envoye. Il s’agissait pour 80,5 % des cas d’internes et pour 19,5 % des cas de chefs de clinique ou assistants. L’âge moyen etait de 29,2 ans (25–36). Trente-deux d’entre eux etaient issus d’un CHU parisien (41,6 %) et 45 (58,4 %) d’un CHU de province. Une activite hospitaliere est souhaitee par 40,3 % d’entre eux, 27,3 % une activite exclusivement liberale. 81,8 % des internes et chefs de clinique interroges declaraient etre interesses par l’andrologie et 29,9 % etaient inscrits ou souhaitaient s’inscrire au diplome d’etudes specialisees complementaires (DESC) d’andrologie. Concernant la formation actuellement proposee, seuls 4 % des participants estimaient que l’enseignement theorique de l’andrologie etait suffisant et seuls 6,6 % d’entre eux consideraient avoir acquis une formation pratique en andrologie satisfaisante au cours du cursus. Conclusion L’andrologie est une specialite particulierement attractive pour les urologues en formation et les modalites d’enseignement actuelles sont jugees insuffisantes par la plupart d’entre eux.

Prevalence of erectile dysfunction (ED) has a higher incidence in patients treated for diabetes mellitus as it concerns more than 30% of them. ED's physiopathology is complex and multifactorial, involving a combination of classical risk factors (endothelial dysfunction), specific factors (e.g., diabetic neuropathy) and psychological factors. ED is most often forewarning a cardiovascular disease. Therefore, it needs to be detected by the physician who is taking care of the diabetic patient. ED is responsible for a deterioration of the quality of life. Therapeutic management relies, on one hand, on specific measures such as prevention of diabetic complications and, on the other hand, on psychological accompaniment of the patient. Phosphodiesterase-5 inhibitors have become the first-line treatment as they are efficient and safe in most cases. As a second line, intracavernous injections remain a gold-standard treatment but the vacuum can be proposed as well. In case of failure, penile prosthesis can even be considered. The psychological dimension of ED has to be considered as much as organic matters.

International audience; IntroductionL’Evidence-Based Medicine (EBM) est indispensable à l’exercice de la médecine. Notre objectif était de connaître quel en était son niveau de connaissance par les étudiants français. Matériel et Méthodes Entre avril et mai 2008, un questionnaire a été envoyé par courriel à 900 étudiants en dernière année du deuxième cycle des études médicales participant à des conférences publiques ou privées d’internat. Résultats Sur les 327 réponses, 297 (91%), 94 (29%) et 85 (26%) étudiants déclaraient savoir lire, écrire et parler l’anglais médical. Quatre-vingt-dix étudiants (28%) lisaient un article d’une revue médicale française, une fois par mois et 43 (13%) lisaient un article d’une revue médicale internationale une fois par mois. Trois cent onze (95%) connaissaient les bases de recherche médicale sur Internet et 219 (67%) les utilisaient. Vingt-quatre (7%) avaient déjà participé à la rédaction d’un article médical, sept (2%) avait été co-auteurs. Deux cent soixante-douze (83%) avait réalisé une présentation orale lors d’un staff médical et trois (1%) lors d’un congrès. Enfin, 237 (73%) comprenaient l’intérêt de l’épreuve d’analyse critique d’article à l’examen national classant (ECN) et 70 (21%) pensaient y être préparés. Conclusion L’insuffisance de l’apprentissage de l’EBM est une des limites du système de formation français. L’introduction de la lecture critique d’article (LCA) à l’ECN est un début de réponse concret à ce problème.

Erectile dysfunction (ED) has a higher incidence in patients treated for chronic renal insufficiency or in patients who underwent kidney transplanation as it concerns more than 50% of them. Its severity is directly linked with the seriousness of the renal disease. ED is responsible of a deterioration of the quality of life. ED's physiopathology is complex and multifactorial, involving a combination of classical risk factors (endothelial dysfunction), specific factors (e.g., chronic hyperuremia and co-morbidities) and psychological factors. Management of ED must take into account both sides of the disease in order to propose appropriate treatment; i.e, psychological concerns and organic matters. Although literature remains poor in this area, phosphodiesterase-5 inhibitors are increasingly used for these patients as they are safe and efficient most of the time. Pharmacokinetics of phosphodiesterase-5 inhibitors can be disturbed by the simultaneous use of immunosuppressor. As a second line, intra-cavernous injections remain a gold-standard treatment. In case of failure, penile prosthesis can even be considered in case of renal chronic insufficiency and in transplanted patients.

Resume Introduction et objectifs La preparation de l’examen classant national (ECN) est une preoccupation majeure des etudiants hospitaliers (EH). Il existe de nombreux supports pedagogiques pour preparer le module d’urologie : polycopies de la faculte et ouvrages d’urologie communement appeles « poly d’uro ». Le but de cette etude a ete de determiner les criteres de selection des EH pour choisir leur support pedagogique en urologie pour preparer l’ECN. Materiel et methode Un questionnaire a ete distribue a 200 EH (DCEM3 et 4) preparant l’ECN. Ce questionnaire comprenait trois parties : (1) les informations sur l’etudiant (faculte d’origine, assiduite aux cours, participation a des conferences d’internat) ; (2) le degre de satisfaction de l’etudiant vis-a-vis des supports pedagogiques mis a sa disposition ; (3) les criteres de choix (18 items) du polycopie utilise. Resultats Parmi les 200 etudiants interroges, seuls 32 % travaillaient sur les supports pedagogiques fournis par l’universite et 22 % affirmaient que leur faculte ne leur fournissait pas de support en urologie. Concernant ce support, 59 % pensaient qu’il etait « moyennement » a « pas du tout adapte » au programme de l’ECN et 70 % pensaient qu’ils etaient « moyennement » a « pas du tout » prepares a l’ECN. On notait que 83,5 % des etudiants pensaient que les conferences d’internat etaient « utiles » a « tres utiles » pour preparer l’ECN en urologie et 85 % d’entres eux pensaient qu’un polycopie etait « utile » a « tres utile » pour preparer l’ECN. Le polycopie du College d’urologie etait le support le plus utilise : 38 % des etudiants interroges. Les quatre criteres de choix les plus importants etaient « l’avis de leur entourage », « le style de presentation et de redaction » et « les conseils de leurs aines internes ». « L’auteur » et « le prix » etaient des considerations qui n’arrivaient qu’en onzieme et douzieme position. Conclusion Dans notre etude, les etudiants semblent juger insuffisante et inadaptee l’offre de la faculte pour les preparer a l’epreuve de l’ECN en urologie. En revanche, le polycopie du College d’urologie leur apparait comme un outil de travail satisfaisant en termes de presentation et de redaction.

Resume But Etudier la prevalence et la severite de la dysfonction erectile (DE) dans une population de patients pris en charge en urgence pour une coronaropathie averee. Materiel Les dossiers de 200 patients ayant eu une coronarographie pour syndrome coronarien aigu avant le 1er janvier 2007 ont ete revus retrospectivement. Les donnees epidemiologiques et le detail des lesions coronaires ont ete releves. Ont ete exclus les patients de plus de 65 ans, en cas d’antecedents de chirurgie ou d’irradiation prostatique. Le questionnaire international index of erectile function (IIEF-5) a ete adresse par courrier. Les patients ont ete classes en quatre groupes en fonction de leur DE : « pas de DE » entre 21 et 25 inclus, « DE legere » inferieure a 21, « DE moderee » inferieure a 17 et « DE severe » inferieure a dix. Resultats Au total, 78 patients ont ete inclus dont l’âge median etait de 58 ans. La prevalence de la DE etait de 0,82 et la duree mediane d’evolution de la DE avant le syndrome coronarien etait de neuf mois. Quarante-neuf patients (62,8 %) avaient une DE moderee a severe. La DE etait associee avec le groupe des patients fumant plus de dix paquets-annees (P/A) (n = 44 ; p = 0,01) et avec le groupe des patients de plus de 60 ans (n = 38 ; p = 0,02). Il existait une association entre l’atteinte coronarienne severe et une DE moderee a severe (p = 0,03). Conclusion Notre etude confirme l’existence d’un lien epidemiologique fort entre la DE et la dysfonction coronarienne, notamment chez les sujets de moins de 65 ans. Il semble, par ailleurs, que la severite de la DE soit en relation avec la severite « anatomique » de l’atteinte coronarienne.

The fact that external beam radiotherapy and brachytherapy are now considered to be curative techniques has led to major review of the modalities of follow-up after radiotherapy for prostate cancer. The problem concerns both the diagnosis of recurrence, rapidly announced by elevation of prostatic-specific antigen (PSA), usually at a subclinical stage, and the validity of criteria of biochemical recurrence to allow comparison of various study. Physicians involved in follow-up should be aware of the potential of bounce in PSA follow-up after external beam radiotherapy or brachytherapy. The PSA bounce phenomemon was defined by a rise of PSA values (+0.1 -0.8 ng/ml) with a subsequent fall. Biochemical failure after external beam radiotherapy or brachytherapy (with or without hormonotherapy) was defined by Phoenix criteria by a rise of 2 ng/ml above an initial PSA nadir. This definition was more correlated to PSA bounce phenomenon.

Resume Objectif Etudier l’interet d’une stimulation visuelle sexuelle combinee aux injections intra-caverneuses (IIC) chez les patients traites pour une dysfonction erectile severe. Materiels et methodes Entre 2005 et 2006, tous les patients ayant une dysfonction erectile severe ont ete inclus prospectivement. Le protocole en consultation consistait a comparer l’efficacite d’une IIC seule d’alprostadil a J0, puis d’une IIC combinee a une stimulation erotique a J8. Les criteres de jugement etaient : le delai d’apparition et la rigidite de l’erection. Une echelle de cotation subjective (1 a 5) a permis de quantifier l’erection. Resultats Quarante patients ont ete inclus. L’âge moyen etait de 64,5 ans (52-70). Tous les patients avaient un score IIEF5 inferieur a 15. Un acte de chirurgie urologique etait a l’origine de la dysfonction erectile dans 35% des cas. A JO et a J8, le delai moyen d’obtention de l’erection a ete respectivement de 10 mn 18 s (2-20) et de 10 mn 50 s (2-20). Concernant la rigidite et la qualite de l’erection, aucune difference significative n’a ete constatee entre J0 et J8 et les erections ont ete evalues respectivement a 5 dans 30 cas (75%), a 4 dans 8 cas (20%) et a 3 dans 2 cas (5%), lors de chaque consultation. Conclusion La stimulation visuelle sexuelle n’a pas fait la preuve de son efficacite reelle en milieu hospitalier en association avec les injections intra-caverneuses. Pour augmenter le taux de satisfaction des patients, l’urologue doit veiller avant tout a eduquer le patient aux injections intra-caverneuses dans un environnement adapte. Objective To assess the value of visual sexual stimulation combined with intracavernous injections (ICI) in patients treated for severe erectile dysfunction. Materials and methods Al1 patients with severe erectile dysfunction were prospectively included in this study between 2005 and 2006. The outpatient protocol consisted of comparing the efficacy of alprostadil ICI alone on DO and ICI combined with erotic stimulation on D8. Endpoints were: time to onset and rigidity of erection. A subjective score (1 to 5) was used to quantify erection. Results Forty patients with a mean age of 64.5 years (range: 52-70 years) were included in the study. Allpatients had an IIEF5 score less than 15. Erectile dysfunction was secondary to uroiogical surgery in 35% of cases. The mean time to onset of erection was I0 min 18 s (range: 2-20 min) on D0 and 10 min 50 s (range: 2-20 min) on D8. No signifcant difference for rigidity and quality of erection was observed between D0 and D8 and erections were scored as 5 in 30 cases (75%), 4 in 8 cases (20%) and 3 in 2 cases (5%) at each visit. Conclusion Visual sexual stimulation has not been demonstrated to be truly effective in the hospital setting in combination with intracavernous injections. In order to increase the patient satisfaction rate, the urologist must above al1 educate the patient in the intracavernous injection technique in an appropriate environment.

Materiels et methodes Depuis 2004, tous les internes nommes en chirurgie a Paris ont participe a un stage d’initiation a l’urologie avant de prendre leur fonction hospitaliere. Un questionnaire leur a ete remis. L’enquete prospective s’est interessee a : l’âge, le sexe, l’existence d’un stage d’urologie pendant l’externat et au souhait d’orientation au sein des 11 disciplines chirurgicales. Les internes ont ete recontactes annuellement pour connaitre l’evolution de leur orientation professionnelle. Resultats Population. Deux cent cinquante cinq internes ont participe dont 145 femmes (56,9%) et 110 hommes (43,1%). L’âge moyen etait de 24,6 ± 5 ans (22-31). 173 internes etaient issus d’un CHU parisien (67,8%) et 82 (32,2%) d’un CHU de province. Cinquante deux internes (21,2%) avaient effectue au moins un stage dans un service d’urologie pendant leur externat. Disciplines chirurgicales. L’orthopedie a ete le plus souvent citee (n=48; 28,9%). L’urologie a ete choisie par 32 internes (12,5%) qui avaient effectue un stage d’externe dans la specialite dans 28 cas. A la fin du stage, 18 internes etaient tentes par l’urologie. A un an, 31 internes134 (91,2%) ont confirme leur choix pour I’urologie. Conclusion La realisation d’un stage pratique intervenant tres tot dans la formation des jeunes chirurgiens est une bonne solution pour les initier a l’urologie. En beneficiant d’un choix eclaire, les internes les plus motives sont incites a rejoindre volontairement notre discipline.

La prostatectomie radicale est le traitement de reference du cancer de la prostate. Son diagnostic precoce, a un stade limite, autoriseunmeilleur controle carcinologique mais pose le probleme de la dysfonction erectile postoperatoire. Celle-ci depend de la fonction erectile initiale, de l’âge du patient et de la technique chirurgicale employee. Elle peut etre amelioree par une reeducation medicamenteuse precoce. En cas de resultat insuffisant, des traitements medicamenteux et chirurgicaux ont montre leur efficacite.

Objectifs Evaluer de facon prospective la prise en charge de la prostatectomie radicale cœlioscopique robotique (PRR) en unite de chirurgie ambulatoire (UCA). Methodes Entre le 15/3/16 et le 31/5/16, 14 PRR ont ete realisees par le meme operateur au sein de notre equipe. Huit PRR ont ete programmees en UCA, apres avoir donne aux patients une information conforme aux recommandations de la HAS pour toute chirurgie ambulatoire. Les interventions ont ete realisees en 1 re position le matin, suivant un protocole anesthesiste per- et postoperatoire specifique permettant la recuperation rapide apres chirurgie (RRAC). Les criteres de sortie etaient : EVA e et la 6 e heure, redon 3 . La sortie a ete validee apres visite du chirurgien et de l’anesthesiste, en respectant les criteres de securite de l’UCA, et en accord avec le patient. L’appel du lendemain a permis d’evaluer la qualite de la nuit postoperatoire a domicile. Resultats Toutes les PRR ont ete realisees en cœlioscopie transperitoneale, sans curage ilio-obturateur, avec preservation bilaterale des bandelettes neurovasculaires. Six des 8 patients programmes en UCA ont pu sortir le soir meme, donc moins de 12 h apres l’entree. Aucun de ces 6 patients n’a du etre readmis apres la sortie. Deux patients n’ont pas pu sortir pour des raisons administratives. Tous les patients appeles le lendemain se sont declares satisfaits d’avoir pu passer la nuit a leur domicile. Tous les patients ont ete revus au 6 e jour postoperatoire pour ablation de sonde vesicale. Les donnees principales sont resumees dans le Tableau 1 . Conclusion La PRR peut etre proposee en UCA, sans en augmenter le risque de complications. La prise en charge en UCA diminue le stress lie a l’hospitalisation en permettant un retour rapide au domicile (

International audience; Erectile dysfunction (ED) currently affects 152 million men worldwide and this number is likely to reach 322 million by 2025. Penile prostheses (PP) placement remains a lastresort option in cases where organic ED has not been cured by previous medications, notably intracavernosal injection and oral phosphodiesterase type-5 inhibitor. France ended 2013 with a population of 66 million inhabitants. In our study, we obtained data through the French national code registry database programme de médicalisation des systèmes d’information and from the patient-information forms filled out by the surgeon at the time of the implant. For claim purposes, this system comprehensively records information concerning every surgical procedure that is performed in a private or public hospital in France. Data were extracted for all patients who had undergone a penile implantation between 1997 and 2013.

We present measurement results and spatial-spectrum shapes of the dependence of the relaxation time on the scale across the geomagnetic field for artificial ionospheric irregularities (AIIs) induced in the upper ionosphere by powerful HF radiation of the SURA heating facility. The irregularity diagnostics was based on observing amplitude scintillations of a 243-MHz beacon signal from a quasi-geostationary, solar-synchronous satellite and on measuring field-aligned scattering at frequencies 15 and 20 MHz. The satellite signal was received at the Kazan State University Observatory. The field-aligned scattering signals were received and analyzed by a bistatic HF radar based on the UTR-2 radio telescope located near Kharkov (Ukraine). It is shown that irregularities of the electron density, whose two-dimensional spectrum in the plane perpendicular to the geomagnetic field is the power law ae⊥-p with index p≲2, are developed in the scale range 30–60 ≲ l⊥ ≲ 200–400 m. In this case, the relative fluctuations (〈δN2〉)1/2 of the electron density increase with decreasing scale l⊥=2π/ae⊥. The estimate 〈δ N2〉)1/2 ≲ 1–1.5% is obtained for a heating power of 150 MW and irregularity scales l⊥ ∼ 30–60 m at which the fluctuations are maximum. The measured dependence of the AII relaxation time, defined as the e-folding time of the amplitude-scintillation intensity, has the form τr ∝ l⊥α. If l⊥ ≲ 30–60 m, then the index α is close to 2, whereas the effective diffusion coefficient D⊥ ≃ (2–3)· 10-1 m2/s corresponds to the ambipolar cross-field diffusion coefficient in a magnetized plasma. The time τr for scales l⊥≳ 60–100 m is independent of l⊥ and increases with decreasing velocity of regular drift of the plasma. The Doppler-spectrum broadening (〈Δν2〉)1/2 ≲ 0.6 Hz observed when receiving field-aligned scattered signals can be related to chaotic motions of plasma-density disturbances whose random drift velocities amount to (〈Δv2〉)1/2 ≃ 2–3 m/s for scales l⊥ ∼ 20 m at which the power-law index changes drastically.

In late March and early April of 1995, an experimental campaign involving the modification of the F2 ionospheric layer took place in Russia and Ukraine. HF pulsed and CW Doppler radar observations of field-aligned irregularities within the region over the Sura heater were made with the UTR-2 radio telescope serving as the receiver. In this paper, some preliminary results of our bistatic radar observations of the modified region are presented. These results include measurements of the drift, evolution, and decay of inhomogeneities and turbulence contained within the modified region and evidence of interactions between the ionospheric plasma, Alfven waves, and free geomagnetic pulsations.

The first observations of ion acoustic waves at altitudes of about 4000 km in the auroral zone were carried out using the powerful SURA HF radar in 1991. Here we report additional observations made with the Russian SURA radar and the Ukrainian UTR 2 receiving system in December 1992. Although echoes similar to the earlier observations were detected, we performed a number of diagnostics and have concluded that no unambiguous magnetospheric echoes were seen at SURA during the 1992 campaign. (There is some indication that the more sensitive UTR 2 system received magnetospheric echoes.) Some aspects of the coding scheme used in the experiments that might lead to spectral artifacts are discussed. A new antenna under construction at SURA will allow transmission at twice the frequency used to date and should permit more definitive observations in the future.

To conduct a review about the use of single incision mini-slings (SIMS) to manage non-neurogenic stress urinary incontinence in women.Literature search in Pubmed/MEdline database until june 2013. TVT-Secur™ was excluded because this device is not anymore marketed.Ajust™ and Mini-Arc™ were the two main SIMS evaluated in the literature. Studies about Mini-Arc™ generated heterogeneous results, with a success rate between 44% and 91% after 1 year. Ajust™ was the most promising device with 80% efficacy after mid-term follow-up. All evaluated SIMS had a low rate of immediate complications. Two randomized controlled trials comparing SIMS and traditional mid-urethral slings were identified, as well as one meta-analysis; they all concluded to non-superiority or inferiority for the mini-sling versus traditional slings.Due to short follow-up, limited evidence and heterogeneous data, SIMS are not yet standard of care and further research is warranted.

Bistatic HF radar scatter from magnetic field-aligned irregularities created by the Sura heater near Nizhny Novgorod, Russia, has been detected and analyzed at the UTR 2 decametric radio telescope near Kharkov, Ukraine. The decay phase of the irregularities exhibits two decay time constants in general. The shorter time constant, which is only sometimes seen, is consistent with classical diffusive dissipation theory for small-scale, field-aligned waves. The longer time constant, which is almost always present, is much too long to be accounted for by diffusion. It is more likely associated with the decay of large- and intermediate-scale plasma turbulence. Three-wave nonlinear interaction with turbulent modes is shown to be capable of generating the field-aligned irregularities.

Radiotherapy of prostate cancers, over the last few years, has been an alternative choice to radical prostatectomy in the case of localised cancers as well as being the preferred treatment in both advanced localised cancers and those of the elderly. A conventional course of prostate radiotherapy consisting of four to five sessions a week, lasts between 7 and 8 weeks plus about one week of preparation.A systematic review of the scientific literature based on Pubmed, along with an exhaustive review of randomised studies presented at international congresses, have made it possible to analyse the numerous therapeutic regimens available other than the conventional normofractioned one (i.e. with doses per session ranging between 1.8 and 2.2 grays).Five randomised trials reported since 2005, plus several thousand patients treated by stereotaxic radiotherapy, have given rise to numerous scientific questions; these alternative hypofractioned courses (dose per fraction higher than 2.2 grays) have a potentially enhanced antitumoral efficacity along with the practical advantages of a shortened duration of radiotherapy.The aim of this analysis of the scientific literature on hypofractioning in prostate cancer radiotherapy is to gather all the scientific evidence we currently have at our disposal. Further mature results of future randomised trials will have to be examined before modifying current practice.

Management of adverse events related to cancer therapies are seen as tertiary prevention. Concerning prostate cancer, dealing with secondary effects of treatments is crucial. Indeed, if recent advances in cancer therapy have lead to an acceptable overall prognosis, these results face increasing cases of adverse events that can dramatically impact quality of life. Localized prostate cancer management (by radical prostatectomy, brachytherapy, external radiation therapy, hormonal treatment) leads to two main secondary effects: bladder and urinary sphincter dysfunction on one hand and sexual disorders on the other hand. Urinary disorders are stress urinary incontinence (mainly after radical prostatectomy), storage symptoms and overactive bladder, and outflow obstruction (mainly after radiation therapy). Stress urinary incontinence can be managed by pelvic floor muscle training and behavioural treatment. In case of failure, and after one year of evolution, surgical options are indicated (periurethral injections, artificial urinary sphincter, tapes and balloons). Storage symptoms respond to medical management (anticholinergics), and obstructive symptoms are treated by alpha-blockers, self-catheterization or surgery if necessary. Sexual disorders are erectile dysfunction, pelvic floor discomfort, orgasm disorder, and penile retraction and fibrosis. Available options gather medical treatment by phosphodiesterase-5 inhibitors, Vacuum, and penile prosthesis. Recent advances in this field point out the role of early penile rehabilitation and prevention of sexual disorders. Although often associated in the same patients, sexual and urinary disorders following prostate cancer management are often considered separately. Their combined treatment should be an objective for both clinical practice and research. New treatments for stress urinary incontinence management (latero-urethral balloons, new male slings) and for erectile dysfunction (penile rehabilitation, treatment penile retraction and optimal use of phosphodiesterase-5 inhibitors) will extend the therapeutic options in the next future, and improve the level of care for patients with prostate cancer.

Stress urinary incontinence (SUI) and erectile dysfunction (ED) are two major complications following radical prostatectomy (RP). In case of failure of medical treatment, Advance™ retrourethral male sling and penile implant are validated options to manage respectively SUI and ED. Our goal was to assess the feasibility and results of the combination of these two devices.Four patients were treated for SUI and DE following RP in our institution by retrourethral sling and penile prosthesis, after failure of medical management. Each patient was preoperatively evaluated by age, complete medical history, ASA score, endoscopy, pad-test, and urodynamics. The first two patients were implanted with the two devices in a two-stage procedure: retrourethral sling then penile prosthesis for one, and penile prosthesis then retrourethral sling for the other. The two other patients underwent a one-stage procedure: one received the two devices, and the other had retrourethral sling implantation and replacement of a penile prosthesis. Post-operative follow-up was focused on complications and efficacy (evaluated by pad use and PGI-I questionnaire for continence, and patient auto-evaluation for sexual function).No perioperative complication occurred. After a minimum of 6 months follow-up, all the four patients were pad-free with no leakage reported, feeling very much better after the procedure according to the PGI-I. The four patients were fully satisfied of the penile implant device.According to our initial experience, surgery combining the transobturator Advance male sling and a penile prosthesis is feasible, successively or simultaneously, and leads to excellent functional results with no complications.
