Uso do estudo urodinâmico por ginecologistas e urologistas no Brasil / Use of the urodynamic study by gynecologists and urologists in Brazil

Objetivo: O estudo urodinâmico (EUD) é um conjunto de exames que estuda o armazenamento e o esvaziamento da urina e é amplamente utilizado por ginecologistas e urologistas na abordagem da incontinência urinária (IU) feminina, apesar da discussão sobre suas indicações. Os objetivos do estudo foram verificar se a urodinâmica é utilizada rotineiramente na abordagem conservadora e cirúrgica da IU feminina, e quais outras indicações clínicas, comparando as respostas entre ginecologistas e urologistas brasileiros. Métodos: Trata-se de uma pesquisa de opinião por meio de um questionário semiestruturado, composto por perguntas sobre a prática clínica em IU, enviado por e-mail a ginecologistas e urologistas, e realizada entre agosto de 2020 e janeiro de 2021. As respostas foram comparadas por meio de análises estatísticas. Resultados: Dos 329 participantes, 238 (72,3%) eram ginecologistas e 91 (27,7%), urologistas. A maioria dos ginecologistas (73,5%) e urologistas (86,6%) não solicita EUD antes do tratamento conservador da IU, mas o EUD é indicado rotineiramente no pré-operatório de cirurgias anti-incontinência. A maioria dos participantes indica EUD na abordagem inicial da bexiga hiperativa (88,2% vs. 96,7%) e há maior chance de o urologista solicitar mais EUD nessa situação (OR = 3,9). Para a maioria dos participantes, é necessário solicitar a urocultura antes do EUD. Conclusão: A maioria dos ginecologistas e urologistas brasileiros não solicita o EUD antes do tratamento conservador da IU, de acordo com as diretrizes nacionais e internacionais, e muitas vezes solicita antes do tratamento cirúrgico da IU feminina. A indicação desse exame na abordagem inicial da bexiga hiperativa idiopática deve ser revisada pelos participantes.(AU)

Frequentist and Bayesian Hypothesis Testing: An Intuitive Guide for Urologists and Clinicians / Pruebas de hipótesis frecuentista y bayesiana: Una Guía intuitiva para urólogos y clínicos

Given the limitations of frequentist method for null hypothesis significance testing, different authors recommend alternatives such as Bayesian inference. A poor understanding of both statistical frameworks is common among clinicians. The present is a gentle narrative review of the frequentist and Bayesian methods intended for physicians not familiar with mathematics. The frequentist p-value is the probability of finding a value equal to or higher than that observed in a study, assuming that the null hypothesis (H0) is true. The H0 is rejected or not based on a p threshold of 0.05, and this dichotomous approach does not express the probability that the alternative hypothesis (H1) is true. The Bayesian method calculates the probability of H1 and H0 considering prior odds and the Bayes factor (Bf). Prior odds are the researcher's belief about the probability of H1, and the Bf quantifies how consistent the data is concerning H1 and H0. The Bayesian prediction is not dichotomous but is expressed in continuous scales of the Bf and of the posterior odds. The JASP software enables the performance of both frequentist and Bayesian analyses in a friendly and intuitive way, and its application is displayed at the end of the paper. In conclusion, the frequentist method expresses how consistent the data is with H0 in terms of p-values, with no consideration of the probability of H1. The Bayesian model is a more comprehensive prediction because it quantifies in continuous scales the evidence for H1 versus H0 in terms of the Bf and the

Dadas las limitaciones del método de significancia frecuentista basado en la hipótesis nula, diferentes autores recomiendan alternativas como la inferencia bayesiana. Es común entre los médicos una comprensión deficiente de ambos marcos estadísticos. Esta es una revisión narrativa amigable de los métodos frecuentista y bayesiano dirigida quienes no están familiarizados con las matemáticas. El valor de p frecuentista es la probabilidad de encontrar un valor igual o superior al observado en un estudio, asumiendo que la hipótesis nula (H0) es cierta. La H0 se rechaza o no con base en un umbral p de 0.05, y este enfoque dicotómico no expresa la probabilidad de que la hipótesis alternativa (H1) sea verdadera. El método bayesiano calcula la probabilidad de H1 y H0 considerando las probabilidades a priori y el factor de Bayes (fB). Las probabilidades a priori son la creencia del investigador sobre la probabilidad de H1, y el fB cuantifica cuán consistentes son los datos con respecto a H1 y H0. La predicción bayesiana no es dicotómica, sino que se expresa en escalas continuas del fB y de las probabilidades a posteriori. El programa JASP permite realizar análisis frecuentista y bayesiano de una forma simple e intuitiva, y su aplicación se muestra al final del documento. En conclusión, el método frecuentista expresa cuán consistentes son los datos con H0 en términos de valores p, sin considerar la probabilidad de H1. El modelo bayesiano es una predicción más completa porque cuantifica en escalas continuas la evidencia de H1 versus H0 en términos del fB y de las probabilidades a posteriori.

Neoplasia de próstata e mieloma múltiplo: um desafio diagnóstico e relato de caso / Prostate neoplasms and multiple myeloma: a diagnostic challenge and case report / Neoplasias de próstata y mieloma múltiple: un desafío diagnóstico y reporte de caso

Este relato aborda o caso de um homem de 52 anos, portador de neoplasia prostática (Gleason 3 + 3), que deu entrada no pronto-socorro com quadro de lesão renal aguda, anemia normocrômica e normocítica e relato de fratura patológica. Encaminhado para o hospital geral, foi iniciada a investigação do quadro. Alguns achados em exames laboratoriais, como inversão da relação albumina-globulina e lesões líticas em exame de imagem, fizeram os médicos levantarem um importante diagnóstico diferencial no contexto de metástase óssea e neoplasias: o mieloma múltiplo. Diante disso, foi indicado aspirado de medula óssea e imunofetipagem, que, surpreendentemente, teve como resultado principal a presença de 12% de células plasmocitárias com caraterísticas anômalas. O tratamento inicial foi estabelecido com dexametasona, ciclofosfamida e pamidronato com melhora progressiva dos parâmetros laboratoriais e clínicos, sendo encaminhado para acompanhamento ambulatorial em cidade de origem com onco-hematologista e urologista.

This study describes the case of a 52-year-old male patient with prostate cancer (Gleason 3+3) admitted to the emergency room with acute kidney injury, normochromic and normocytic anemia, and a pathological fracture report. The patient was referred to the General Hospital to investigate the condition. Laboratory tests indicated inversion of the albumin-globulin ratio and imaging exams evinced lytic lesions, leading physicians to raise an important differential diagnosis in the context of bone metastases and neoplasms: multiple myeloma. Bone marrow aspirate and immunophetyping indicated the presence of 12% plasma cells with anomalous characteristics. After initial treatment with dexamethasone, cyclophosphamide, and pamidronate, the patient showed progressive improvement in laboratory and clinical parameters, being referred for outpatient follow-up in the city of origin with an onco-hematologist and urologist.

Este es un reporte de caso de un varón de 52 años de edad, con cáncer de próstata (Gleason 3 +3) ingresado en urgencias por lesión renal aguda, anemia normocrómica y normocítica y reporte de fractura patológica. Derivado al Hospital General, se inició una investigación de la condición. Algunos hallazgos en las pruebas de laboratorio, como la inversión del cociente albúmina globulina y las lesiones líticas en los exámenes de imagen, llevaron a los médicos a plantear un importante diagnóstico diferencial, en el contexto de las metástasis óseas y las neoplasias: el mieloma múltiple. Por tanto, se indicó el aspirado de médula ósea y la inmunofenotipificación, que sorprendentemente tuvo como principal resultado la presencia de un 12% de células plasmáticas con características anómalas. Se estableció el tratamiento inicial con dexametasona, ciclofosfamida y pamidronato, con mejoría progresiva de los parámetros analíticos y clínicos, siendo remitido para seguimiento ambulatorio en su ciudad de origen con un oncohematólogo y un urólogo.

Estado de la urología reconstructiva en Colombia: Tratamiento de la estrechez uretral anterior, una encuesta nacional / Status of Reconstructive urology in Colombia: Treatment of Anterior Urethral Stricture, A National Survey

Purpose El tratamiento mínimamente invasivo de la estrechez uretral tiene altas tasas de recurrencia y re-operación a largo plazo, no obstante, encuestas realizadas en otros países han demostrado que los urólogos tienen poca experiencia con la uretroplastia abierta y hay una preferencia a la utilización de las terapias endoscópicas mínimamente invasivas. El objetivo de este estudio, es describir patrones de práctica del tratamiento de la estrechez de uretra anterior en nuestro país. Métodos Se trata de un estudio observacional descriptivo y para ello se realizó un cuestionario adaptado a nuestro contexto nacional, basado en varios estudios previamente realizados acerca de la experiencia en Urología reconstructiva. Ese cuestionario incluía información sobre la edad, nivel de experiencia en urología general, la experiencia en urología reconstructiva, escenario de la práctica y las técnicas preferidas para el manejo de las estrecheces uretrales pendulares y bulbares. La información fue almacenada de forma anónima, los datos fueron analizados mediante el paquete estadístico SPSS y se realizó un análisis de distribución de frecuencias. Resultados Se obtuvieron 106 respuestas de los urólogos encuestados. Para el tratamiento de la estrechez uretral pendular la mayoría de los urólogos prefiere el manejo endoscópico mínimamente invasivo, seguido de uretroplastia con injerto con porcentajes de 69,9% y 25,5% respectivamente. Solo el 5% prefiere derivar a sus pacientes a un centro especializado. Para la estrechez de la uretra bulbar se prefiere las técnicas mínimamente invasivas, uretroplastia y remisión a un centro especializado en un 44,3%, 41,5% y 14,2% respectivamente. La población más joven y con formación urológica más reciente tiende a hacer más a menudo la uretroplastia con injerto y menos manejo endoscópico, específicamente la uretrotomía interna. En las ciudades intermedias, hay una predilección por el tratamiento endoscópico, especialmente uretrotomía interna. Conclusiones El enfoque de tratamiento mínimamente invasivo de la estrechez uretral es el más frecuentemente elegido a pesar de sus pobres tasas de éxito a largo plazo. Es de destacar que las nuevas generaciones de urólogos muestran más interés y dominio de las técnicas abiertas, tratamiento estándar hoy en día y con bajas tasas de recaídas y reoperación a largo plazo.

The minimally invasive treatment of urethral stricture has higher recurrence and longterm re operation rates. Surveys in other countries have shown that urologists have little experience with open urethroplasty with a preference to the utilization of minimally invasive therapies. We applied a survey to obtain data about practice patterns of the anterior urethral stricture treatment in our country. Methods A survey was performed with adapted questions to our national context based on several surveys previously conducted in other countries about experience in Reconstructive Urology. This questionnaire included information about age, experience level in general urology, experience in reconstructive urology, scenario of practice, and the preferred techniques handling the pendular and bulbar urethral strictures. All information was collected anonymous and data were analyzed using the statistical software package SPSS, and a frequency distribution analysis was performed. Results A total of 106 answers from respondent urologists were obtained. For the treatment of pendular urethral strictures the vast majority of respondents prefer the minimally invasive endoscopic treatment, following by graft urethroplasty with percentages of 69.9% and 25.5% respectively. Only 5% prefer to refer their patients for care at a specialized center. Regarding the bulbar urethral the urologists prefers to perform minimally invasive management, followed by urethroplasty and refer to a specialized center in percentages of 44.3%, 41.5% and 14.2% respectively. The younger and more recent urological trained population tends to make more often graft urethroplasty and less endoscopic management, specifically internal urethrotomy. In the intermediate cities there is a predilection for endoscopic treatment especially internal urethrotomy. Conclusions The minimally invasive treatment approach of urethral stricture is the most frequently chosen despite its poor long-term success rates. It is noteworthy that the new generations of urologists show more interest and mastery of open techniques, which today is the standard treatment with low relapse and long-term re operation rates.

Factores de riesgo y estrategias de prevención para el desarrollo de estrechez uretral de origen iatrogénico: Papel del urólogo / Risk Factors and Prevention Strategies for the Development of Urethral Stricture of Iatrogenic Origin: Role of the Urologist

La estrechez uretral constituye una patología con morbilidad importante en el sexo masculino. Se evidencia en la actualidad un cambio en la frecuencia de las etiologías, con la disminución de causas inflamatorias y una transición hacia la iatrogenia como la más común. Mediante la búsqueda del estado del arte en cuanto a los procedimientos diagnósticos y terapéuticos conocidos como factores asociados a la estrechez uretral iatrogénica, se realizó una revisión narrativa de la literatura con el fin de describir y generar estrategias para su prevención. De los procedimientos terapéuticos que originan la estrechez uretral como complicación, el sondaje vesical es la mayor causa (hasta 34,3%), seguido de la prostatectomía radical (29,9%). Una buena técnica de sondaje vesical orientada desde el adecuado entrenamiento del personal disminuye de forma considerable su incidencia. Por otra parte, la adecuada selección de tratamientos y aspectos técnicos en pacientes que requieren el manejo de patologías obstructivas del tracto urinario como la hiperplasia prostática y litiasis u oncológicas como el cáncer de próstata, son unas de las recomendaciones para la prevención de ese trastorno. El entendimiento de los factores de riesgo y la adherencia a las estr

Urethral stricture is a pathology with significant morbidity in men. There is current evidence of a change in the prevalence of etiologies, with a decrease in inflammatory causes and a transition towards iatrogenesis as the most frequent. Through the search for the state of art in terms of diagnostic and therapeutic procedures known as associated factors to iatrogenic urethral stricture, a narrative review has been performed, in order to describe and recommend strategies for its prevention. Of the therapeutic procedures that cause urethral stricture as a complication, bladder catheterization is the main (up to 34.3%), followed by radical prostatectomy (29.9%). A good bladder catheterization technique guided by adequate training of personnel considerably reduces its incidence. On the other hand, the proper selection of treatments and technical aspects in patients who require the management of obstructive pathologies of the urinary tract such as prostatic hyperplasia and lithiasis or oncological diseases such as prostate cancer, are some of the recommendations for the prevention of this disorder. Understanding risk factors and adherence to the prevention strategies described seek to reduce the incidence of iatrogenic urethral stricture

Impact of COVID-19 on clinical practice, income, health and lifestyle behavior of Brazilian urologists

ABSTRACT Objectives To evaluate the impact of COVID-19 on clinical practice, income, health and lifestyle behavior of Brazilian urologists during the month of April 2020. Materials and Methods A 39-question, web-based survey was sent to all urologist members of the Brazilian Society of Urology. We assessed socio-demographic, professional, health and behavior parameters. The primary goal was to evaluate changes in urologists' clinical practice and income after two months of COVID-19. We also looked at geographical differences based on the incidence rates of COVID-19 in different states. Results Among 766 urologists who completed the survey, a reduction ≥ 50% of patient visits, elective and emergency surgeries was reported by 83.2%, 89.6% and 54.8%, respectively. An income reduction of ≥ 50% was reported by 54.3%. Measures to reduce costs were implemented by most. Video consultations were performed by 38.7%. Modifications in health and lifestyle included weight gain (32.9%), reduced physical activity (60.0%), increased alcoholic intake (39.9%) and reduced sexual activity (34.9%). Finally, 13.5% of Brazilian urologists were infected with SARS-CoV-2 and about one third required hospitalization. Urologists from the highest COVID-19 incidence states were at a higher risk to have a reduction of patient visits and non-essential surgeries (OR=2.95, 95% CI 1.86 - 4.75; p< 0.0001) and of being infected with SARS-CoV-2 (OR=4.36 95%CI 1.74-10.54, p=0.012). Conclusions COVID-19 produced massive disturbances in Brazilian urologists' practice, with major reductions in patient visits and surgical procedures. Distressing consequences were also observed on physicians' income, health and personal lives. These findings are probably applicable to other medical specialties.

Staghorn renal stones: what the urologist needs to know

ABSTRACT Patients with staghorn renal stones are challenging cases, requiring careful preoperative evaluation and close follow-up to avoid stone recurrence. In this article we aim to discuss the main topics related to staghorn renal stones with focus on surgical approach. Most of staghorn renal stones are composed of struvite (magnesium ammonium phosphate) and are linked to urinary tract infection by urease-producing pathogens. Preoperative computed tomography scan and careful evaluation of all urine cultures made prior surgery are essential for a well-planning surgical approach and a right antibiotics choice. Gold standard surgical technique is the percutaneous nephrolithotomy (PCNL). In cases of impossible percutaneous renal access, anatrophic nephrolithotomy is an alternative. Shockwave lithotripsy and flexible ureteroscopy are useful tools to treat residual fragments that can be left after treatment of complete staghorn renal stone. PCNL can be performed in supine or prone position according to surgeon's experience. Tranexamic acid can be used to avoid bleeding. To check postoperative stone-free status, computed tomography is the most accurate imaging exam, but ultrasound combined to KUB is an option. Intra-operative high-resolution fluoroscopy and flexible nephroscopy have been described as an alternative for looking at residual fragments and save radiation exposure. The main goals of treatment are stone-free status, infection eradication, and recurrence prevention. Long-term or short-term antibiotic therapy is recommended and regular control imaging exams and urine culture should be done.

COVID-19: Measures to prevent hospital contagion. what do urologists need to know?

ABSTRACT A new outbreak of respiratory infection caused by the novel coronavirus in late December 2019 in China caused standards of medical care to change not only for related areas but for the entire healthcare system, and when the WHO declared COVID-19 a pandemic new strategies of patient care had to be defined initially to optimize resources to confront the pandemic and then to protect healthcare personnel. As urologists, we must be involved in these new standards, since without an effective vaccine the risk of contagion is high; thus, the purpose of this review is to have orientation on the measures urologists should take in their everyday clinical practice.

Emergency Surgery in Urology during the COVID-19 Pandemic

ABSTRACT Proposal: To highlight the indications for emergency surgery during the 2019 Coronavirus pandemic (COVID-19) that support recommendations published in midMarch 2020 by the American Confederation of Urology on its website. Materials and Methods: A bibliographic search was conducted in PubMed and Cochrane Library to perform a non-systematic review, using key words: Urology, Emergency and COVID-19, to determine recommendations for patients that should receive emergency care due to urological pathology. Results: The main recommendations and protocols in the management of different urological emergencies during the COVID-19 pandemic are reviewed and discussed. Conclusions: We are living a new condition with the COVID-19 pandemic, which obliges urologists to conform to the guidelines that appear on a daily basis formulated by multidisciplinary surgical groups to manage urological emergencies. Consequently, in this time of health crisis, we must adapt to the resources available, implementing all biosecurity measures to protect patients and all health personnel who are in charge of patient management.

Impact of Covid-19 on the urology service in United States: perspectives and strategies to face a pandemic

ABSTRACT Over the course of several weeks following the first diagnosed case of COVID-19 In the U.S., the virus rapidly spread across our communities. It became evident that the pandemic was going to place a severe strain on all components of the U.S. healthcare system, and we needed to adapt our daily practices, training and education. In the present paper we discuss four pillars to face a pandemic: surgical and outpatients service, tele-medicine and tele-education. In the face of unprecedented risks in providing adequate health care to our patients during this current, evolving public health crisis of COVID-19, alternative patient management tools such as telemedicine services, allow clinicians to maintain necessary patient rapport with their healthcare provider when required. As a subspecialty, urology should take full advantage of telehealth and teleeducation at this juncture. As tele-urology and tele-education can obviate the potential drawbacks of "social distancing" as it pertains to healthcare, the platform can also reduce the risk of COVID-19 spread, without compromising quality urological care and educational efforts. Telehealth can bring urologists and their patients together, perhaps closer than ever.

Laparoscopic and robotic urology surgery during global pandemic COVID-19

ABSTRACT Known laparoscopic and robotic assisted approaches and techniques for the surgical management of urological malignant and benign diseases are commonly used around the World. During the global pandemic COVID-19, urology surgeons had to reorganize their daily surgical practice. A concern with the use of minimally invasive techniques arose due to a proposed risk of viral transmission of the coronavirus disease with the creation of pneumoperitoneum. Due to this, we reviewed the literature to evaluate the use of laparoscopy and robotics during the pandemic COVID-19. A literature review of viral transmission in surgery and of the available literature regarding the transmission of the COVID-19 virus was performed up to April 30, 2020. We additionally reviewed surgical society guidelines and recommendations regarding surgery during this pandemic. Few studies have been performed on viral transmission during surgery. No study has been made regarding this area during minimally invasive urology cases. To date there is no study that demonstrates or can suggest the ability for a virus to be transmitted during surgical treatment whether open, laparoscopic or robotic. There is no society consensus on restricting laparoscopic or robotic surgery. However, there is expert consensus on modification of standard practices to minimize any risk of transmission. During the pandemic COVID-19 we recommend the use of specific personal protective equipment for the surgeon, anesthesiologist and nursing staff in the operating room. Modifications of standard practices during minimally invasive surgery such as using lowest intra-abdominal pressures possible, controlled smoke evacuation systems, and minimizing energy device usage are recommended.

European Guidelines for Urology Sexual and Reproductive Health 2020. Why is it Worth it to read it? / Guías Europeas en salud sexual y reproductiva 2020. ¿Por qué vale la pena leerlas?

The European urology guidelines have been written since 1996. In 2000, experts included sections on ejaculation disorders and erectile dysfunction.[1] Since then, each year, they are updated with the competition of specialists from different continents. In 2014, authors introduced the term priapism,[2] and they maintained it until 2018. That same year the guidelines were modified based on the new online educational courses designed by the EAU expert panels and a group of young urologists. For the year 2020 and with the consultation of more than 250 experts from 72 countries, the guidelines gathered in a single chapter (Sexual and Reproductive Health) with extensive content that is worth consulting.

Las directrices europeas de urología se redactan desde 1996. En 2000, los expertos incluyeron secciones sobre trastornos de la eyaculación y disfunción eréctil[1]. Desde entonces, cada año se actualizan con el concurso de especialistas de distintos continentes. En 2014, los autores introdujeron el término priapismo,[2] y lo mantuvieron hasta 2018. Ese mismo año se modificaron las guías en base a los nuevos cursos educativos online diseñados por los paneles de expertos de la EAU y un grupo de jóvenes urólogos. Para el año 2020 y con la consulta de más de 250 expertos de 72 países, las guías reunieron en un solo capítulo (Salud Sexual y Reproductiva) un amplio contenido que vale la pena consultar.

Una fuerza en crecimiento: El género femenino en urología / A growing force: the female gender in urology

Aunque la urología continúa siendo una especialidad predominantemente masculina, durante los últimos años ha cambiado la composición. La representación femenina se ha incrementado alrededor de 11 veces desde 1978; un incremento mucho mayor que el visto en otras especialidades.[1] En la actualidad las mujeres en urología representan alrededor del 10% de profesionales y 24% de los residentes[1] [2]; sin embargo, de acuerdo con las proyecciones mundiales necesitamos más urólogos, por tanto, más mujeres en urología. Aún tenemos múltiples factores que pueden limitar tanto el ingreso como la permanencia de las mujeres en el campo laboral, por ejemplo: los patrones de práctica, las promociones dentro del campo académico, el balance vida/trabajo y la equidad en salarios, entre otros.[3] Sin embargo, en la actualidad estos se han ido sorteando de la mejor manera, comprendiendo que es una excelente especialidad para ambos géneros.

Although urology continues to be a predominantly male specialty, over the past few years the composition has changed. Female representation has increased about 11-fold since 1978; an increase far greater than that seen in other specialties.[1] Currently women in urology represent about 10% of practitioners and 24% of residents[1] [2]; however, according to worldwide projections we need more urologists, therefore, more women in urology. We still have multiple factors that can limit both the entry and permanence of women in the field, for example: practice patterns, promotions within the academic field, work/life balance and salary equity, among others.[3] However, currently these factors have been overcome in the best way, understanding that it is an excellent specialty for both genders.

Why Work for Women in Urology? / ¿Por qué trabajar para mujeres en urología?

"Destiny guides our fortunes more favorably than we could have expected" wrote Miguel de Cervantes Saavedra, author of the legendary novel Don Quixote of La Mancha. These words describe exactly what has happened to us over the past year. We met by chance at a urology congress last August in the City of Barranquilla. We took the opportunity to sit down unsuspectingly with coffee in hand and started talking about the big picture of urology in the world and especially in Latin America. We soon realized that despite being born in two countries as different as the United States and Colombia, we both shared similar barriers as women urologists. The truth is that despite the increase in the number of women in careers such as medicine, the growth in terms of medical and surgical specialties is still very low. According to the latest census of the American Urological Association (AUA), female urologists currently make up only 9.9% of the total membership in the US academy.[1] What is contradictory is that many studies have evaluated the change in the workforce that has been occurring in this branch of medicine for a few years, since it is assumed that by 2060 there will be a growth in the number of women of 3.7% versus 1.3% compared to men.[2] These two surprising facts forced us to think about the need to find solutions.

"El destino guía nuestra suerte más favorablemente de lo que podíamos esperar", escribió Miguel de Cervantes Saavedra, autor de la legendaria novela Don Quijote de la Mancha. Estas palabras describen exactamente lo que nos ha ocurrido en el último año. Nos conocimos por casualidad en un congreso de urología el pasado mes de agosto en la ciudad de Barranquilla. Aprovechamos la oportunidad para sentarnos desprevenidamente con un café en la mano y empezamos a hablar sobre el gran panorama de la urología en el mundo y especialmente en Latinoamérica. Pronto nos dimos cuenta que a pesar de haber nacido en dos países tan diferentes como Estados Unidos y Colombia, ambas compartíamos barreras similares como mujeres urólogas. Lo cierto es que a pesar del aumento del número de mujeres en carreras como medicina, el crecimiento en cuanto a especialidades médicas y quirúrgicas es aún muy bajo. Según el último censo de la Asociación Americana de Urología (AUA), en la actualidad las mujeres urólogas representan sólo el 9,9% del total de miembros de la academia estadounidense[1] Lo contradictorio es que muchos estudios han evaluado el cambio en la fuerza laboral que se viene dando en esta rama de la medicina desde hace algunos años, pues se presume que para el año 2060 habrá un crecimiento en el número de mujeres del 3,7% frente al 1,3% de los hombres[2] Estos dos sorprendentes datos nos obligaron a pensar en la necesidad de encontrar soluciones.

Experiencia con la "técnica de Xiao" para reinervación de la vejiga, en pacientes con mielomeningocele y vejiga neurogénica, 8 años de seguimiento, en adultos / Experience with the "Xiao technique" for reinnervation of the bladder, in patients with myelomeningocele and neurogenic bladder, 8 years of follow-up, in adults

Objetivo: Restaurar función de vaciado vesical en pacientes con vejiga neurogénica por medio de la reinervación de la vejiga a través de la creación de reflejo sómato-visceral. Registrar complicaciones neuroquirúrgicas, urológicas y ortopédicas.Evaluar dificultades técnico-quirúrgicas y los resultados de 5 casos realizados en Argentina. Introducción: La vejiga neurogénica es una complicación secundaria al daño neurológico en los pacientes con mielomeningocele (MMC). Para lograr vaciar la vejiga deben realizar cateterismo intermitente. La técnica Xiao se basa en permitir la generación de un arco reflejo somato visceral por medio de una anastomosis entre una raíz eferente donante y la raíz motora S2 S3 que permita el vaciado vesical sin cateterismo. Material y métodos: Por medio de un estudio descriptivo retrospectivo, se analizan los resultados obtenidos luego de realizar la técnica Xiao, en el año 2010, en 5 pacientes con MMC y vejiga neurogénica. Los pacientes fueron operados en el Instituto de Rehabilitación (IREP). Fueron evaluados en forma multidisciplinaria tanto pre como en el postoperatorio por neurocirujanos, neurólogos, urólogos, clínicos y kinesiólogos. Resultados: Los pacientes que presentaron mejores resultados fueron los más jóvenes y los que no presentaban daño estructural de la vejiga al momento de la cirugía, lo que coincide con los resultados compartidos por los demás centros donde fue realizada esta técnica. Conclusiones: La técnica de Xiao puede considerarse una opción para el tratamiento de la vejiga neurogénica. Aunque nuestra serie es muy pequeña para dar conclusiones, los resultados globales de todas las series muestran resultados alentadores.

Objective: To restore bladder function in patients with neurogenic bladder through the reinnervation through restauration of somatic-visceral reflex. Record neurosurgical, urological and orthopedic complications. To evaluate technical-surgical difficulties and the results of 5 cases performed in Argentina. Introduction: Neurogenic bladder is a complication secondary to neurological damage in patients with myelomeningocele (MMC). To achieve emptying of the bladder, intermittent catheterization must be performed. The "Xiao technique" is based on allowing the generation of a visceral somatic-reflex arc by means of an anastomosis between a donor efferent root and the motor root S2-S3 that allows bladder emptying without catheterization. Material and methods: Through a retrospective descriptive study, the results obtained after performing the "Xiao technique" in 5 patients with MMC and neurogenic bladder were analyzed. The patients were operated at the Rehabilitation Institute (IREP). They were evaluated with a multidisciplinary team, both pre and post-surgery. The team was formed by neurosurgeons, neurologists, urologists, clinicians and kinesiologists. Results: The patients who presented the best results were the youngest and those who did not present structural damage of the bladder at the time of surgery, which match the results shared by the other centers where this technique was performed. Conclusions: "Xiao's technique" can be considered an option for the treatment of neurogenic bladder. Although our series is too small to make conclusions, the overall results of all the series show encouraging results

A census of laparoscopic and robotic urological practice: a survey of minimally invasive surgery department of the Brazilian Society of Urology

ABSTRACT Minimally invasive urologic surgery has been developing in Brazil and now is a routine part of care in many regions and patients with different conditions benefit from it. Training in laparoscopic and robotic surgery has evolved and concerns exist both over the quality of surgical training and the practical effect on results of the urological training. This is an unprecedented study which undertook a census to determinate the current state of laparoscopic and robotic urological practice and to know the mains barriers to adequate practice in Brazil. In august 2017, surveys, consisting of an anonymous questionnaire with 15 questions, were sent via internet to the mailing list of the Brazilian Society of Urology (SBU). With these data, activities related to laparoscopy and robotic surgery of our urologists and the mains difficulties and barriers to practice laparoscopy and robotic surgery were evaluated. In our survey, 413 questionnaires were completed. Majority of the responders were currently working in the southeast region of Brazil (52.1%) and 75.5% of the surgeons performed laparoscopic surgery while, only 12.8%, robotic surgery. The lack of experience on the technique and the lack of equipment were the mains barriers and difficulties for not executing laparoscopic and robotic surgeries, respectively. Proper longitudinal training and access to good equipment in minimally invasive surgery are still barriers for urologists in our country.

Prevalencia y manejo de condilomas en población consultante en Chile: estudio "DIACON" / Prevalence and management of condylomas in consulting population in Chile: "DIACON study"

Resumen Introducción: Los condilomas o verrugas genitales (VG) son la infección de transmisión sexual (ITS) más diagnosticada en los centros de ITS en Chile, pero no existen estadísticas poblacionales. Objetivos: Describir la prevalencia de VG en pacientes de 18-60 años que acuden a consulta ambulatoria de dermatología, ginecología y urología; características demográficas de los pacientes y prácticas de diagnóstico y tratamiento. Material y Métodos: A una muestra de especialistas chilenos estratificados por región, población y sexo de pacientes se les proporcionó un diario de registro y aplicó un cuestionario.

Conclusiones: Existe una alta prevalencia de VG, que debería ser tomada en cuenta para planificar las intervenciones de salud pública para abordar este problema.

Introduction: Condylomas or genital warts (GW) are the most frequently diagnosed sexually transmitted infection (STI) in STI centers in Chile, but there are no population statistics available. Objectives: To describe the prevalence of GW in patients from 18-60 years of age who attend outpatient dermatology, gynecology and urology practice; the demographic characteristics of the patients and the diagnostic and treatment tools. Methods: A sample of Chilean specialists stratified by region, population and gender of patients was provided with a logbook and answered a questionnaire. Results: The GW prevalence was 2.44% for the whole group; 3.76% for the 18-34 age group and 1.29% for the 35-60 years group (p = 0.0000). The average age of patients with GW was 29.4 years in women and 32.7 years in men (p = 0.019). The distribution by age was different according to gender and health system. Visual inspection was the most frequent diagnostic method used and imiquimod cream the most common treatment, however, there were differences in the use of diagnostic and therapeutic tools according to the patient's gender, specialty of the doctor and health system. Conclusions: The high prevalence of GW confirmed the need and importance of public health interventions to address this problem.

An Update in the Use of JJ Stents / Actualización en el uso de catéteres JJ

Zoom Image Abstract Introduction Ureteral stents are widely used tools in the daily practice of the urologist due to the fact that they solve the endo- and extraluminal ureteral obstructions, enabling an adequate urine flow. They are the preferred tool because they are easy to insert and versatile, and are used to treat various urologic pathologies; nonetheless, they are not exempt from complications. Objectives To present an update in the use of JJ stents, describing their main associated symptoms and complications, indications and newest developments. Materials and Methods We performed a literature review in the Embase, Pubmed and Google Scholar databases, with the following terms and cross-references: ureteral stent; diagnosis; treatment; and urology, restricting the search to the past 7 years. A total of 428 articles were found, and 49 were used in the revision. Results We described the symptoms and complications associated with the use of JJ stents and their prevention, their use in the treatment of lithiasis and oncologic diseases, the utility of metallic stents, and new designs and improvements in their development. Conclusions JJ stents remain a very useful tool in the daily practice of the urologist, but are not exempt from having adverse effects and complications. There have been advances that decrease the adverse effects associated with their use, mainly infection, symptoms associated to the insertion, and risk of incrustation.
