Trombosis espontánea de plexo pampiniforme: Reporte de un caso y revisión de literatura

Introducción: La trombosis de plexo pampiniforme es una entidad poco conocida, solo existen 31 casos reportados a la fecha. Objetivo: Presentación de un caso de una patología poco frecuente, descripción de las publicaciones anteriores y revisión de la literatura. Reporte de caso: Paciente de 20 años, sin antecedentes, con trombosis de plexo pampiniforme derecho. Sospecha inicial de hernia inguinal derecha complicada, el diagnóstico se realizó con ecografía Doppler y recibió tratamiento con anticoagulantes. Se complementó con tomografía y estudio de trombofilias. Discusión: El estudio y manejo ha sido variable, antes prevalecía la estrategia quirúrgica. Actualmente, algunos autores recomiendan el manejo conservador y otros proponen diferenciar el tratamiento según segmento anatómico comprometido. Conclusión: Al ser una entidad poco frecuente, el tratamiento es una decisión que debe ser tomada según cada caso, ya que no existen pautas de tratamiento, pero la tendencia es cada vez mayor hacia el tratamiento conservador. El rol de la anticoagulación está por definir. Es importante realizar un adecuado diagnóstico diferencial y búsqueda de causas subyacentes.

Introduction: Pampiniform plexus thrombosis is a rare entity, with only 31 cases reported to date. Aim: Presentation of a case of a rare disease, description of previous publications and review of the literature. Case report: 20-year-old patient, with no history, with right pampiniform plexus thrombosis. Initial suspicion was complicated right inguinal hernia, diagnosis was made with Doppler ultrasound and treatment with anticoagulation. It was complemented with tomography and study of thrombophilias. Discussion: The study and management has been variable, where the surgical strategy prevailed. Currently some authors recommend conservative management and others differentiate the treatment according to the compromised anatomical segment. Conclusion: Being a rare entity, conservative treatment or surgery continues to be a decision that must be made according to each case since there are no treatment guidelines, but the trend is increasing towards conservative treatment. The role of anticoagulation remains to be defined. It is important to carry out an adequate differential diagnosis and search for underlying causes.

Pentafecta evaluation in robot-assisted radical prostatectomy by risk group.

OBJECTIVE: Radical prostatectomy is a therapeutic option in organ-confined prostate cancer. As the development of robotic systems progresses, the approach with this technology has begun to impact the functional and oncological outcomes of urological patients. The objective is to report the rate of pentafecta in patients undergoing robot-assisted radical prostatectomy (RARP) stratified by risk groups. METHOD: Retrospective, observational, descriptive study from 2013 to 2020 that included 112 patients undergoing RARP. RESULTS: A rate of pentafecta at 12 months of follow-up of 35.7% (n = 40) was obtained. In the subanalysis by risk groups, at 1-year follow-up, was obtained an index of 43% (n = 26), 26% (n = 9) and 22% (n = 4) in low-, intermediate-, and high-risk patients, respectively. CONCLUSIONS: Prostatectomy showed functional and oncological results similar to those reported in the literature with robotic approach, regardless of the risk group for prostate cancer.

Revisión integrativa sobre evidencia actual de la uretroplastia / Integrative review on current evidence for urethroplasty

La uretroplastía se ha convertido en el estándar de manejo de la estrechez uretral, dependiendo de la localización y etiología de esta. Los datos de los resultados a largo plazo varían dependiendo de la definición que se utilice como éxito (subjetiva u objetiva). El objetivo de esta revisión integrativa es mostrar la información disponible sobre los resultados funcionales de pacientes con estrechez uretral manejados quirúrgicamente. El estudio es una revisión integrativa que se realizó mediante una búsqueda de la literatura en PubMed. Incluimos artículos que describían resultados de pacientes sometidos a reconstrucción uretral con uretroplastia, solo hombres, en inglés o español, publicados entre 1999-2022. Incluimos 34 artículos, los cuales mostraron que, según el tipo de procedimiento realizado, las características de la estrechez uretral y las variables definidas como éxito y fracaso, los factores de riesgo asociados a la recurrencia posterior a la reconstrucción con uretroplastia en uretra fueron la presencia de comorbilidades, obesidad y etiología infecciosa. Concluimos entonces que la uretroplastia es un procedimiento que ha aumentado en los últimos años, con pocos estudios que nos comparan resultados dependiendo del tipo de procedimiento utilizado. Nuestra revisión encontró que hay mayor literatura sobre el uso de injertos de mucosa oral comparado con escición primaria y anastomosis (EPA), con unos resultados anatómicos y funcionales comparables entre ambos procedimientos. Los cuestionarios PROMS (Patient Reported Outcome Measures) son herramientas útiles para el seguimiento postoperatorio de estos pacientes.

Urethroplasty has become the standard for managing urethral stricture, depending on its location and etiology. Long-term outcome data varies depending on the definition of success used (subjective or objective). The objective of this integrative review is to show the available information on the functional results of patients with surgically managed urethral stricture. The study is an integrative review that was carried out through a literature search in PubMed, we included articles that described the results of patients undergoing urethral reconstruction with urethroplasty, only men, in English or Spanish, published between 1999-2022. The study included 34 articles, which showed that, depending on the type of procedure performed, the characteristics of the urethral stricture and the variables defined as success and failure, the risk factors associated with recurrence after reconstruction with urethroplasty in the urethra were the presence of comorbidities, obesity, and infectious etiology. In conclusion, urethroplasty is a procedure that has increased in recent years, with few studies that compare results depending on the type of procedure used. Our review found that there is more literature on the use of buccal mucosa graft (BMG) compared to excision and primary anastomotic urethroplasy (EPA), with comparable anatomical and functional results between both procedures.

Endoscopic implantation of autologous myoblasts for stress urinary incontinence and evaluation of its efficacy in sphincterotomized rabbits.

INTRODUCTION: Stress urinary incontinence (SUI) is one of the health problems with more impact on patients' lives. The aim of the present work was to develop a therapy for SUI using tissue engineering by isolation and culture of autologous myoblasts (CAM) followed by endoscopic implantation. We also evaluated the efficacy of this therapy in a rabbit model of incontinence after sphincterotomy. MATERIALS AND METHODS: We used healthy male New Zealand rabbits. The animals were first bled to obtain platelet-poor plasma (PPP) and biopsied for myoblast isolation. Post-sphincterotomy, they were divided into two groups: the treatment group (including animals that received CAM resuspended in PPP) and the control group (including animals receiving only PPP). The leak-point pressure (LPP) was used to measure continence in both groups at different time points. The results were evaluated with hierarchical linear regression models. Histological evaluation of the rabbits' sphincters was also performed at the end of follow-up. RESULTS: No statistically significant differences were observed between the baseline LPP values of each group. The post-sphincterotomy values of both groups were below 50% of the baseline value, which was a mandatory condition for incontinence. The post-implantation values of the treatment group were higher than 50% of the baseline value, which led us to assume continence recovery. A statistically significant difference was observed in the LPP values between the two treatment groups (p=0.003). Histological study revealed interconnected islands formed by muscle fibers in the treatment group, and connective tissue surrounding the urethral lumen and inflammatory infiltrate in the control group. DISCUSSION AND CONCLUSIONS: The implantation of CAM significantly improved LPP values in the treatment group, and the improvement remained throughout the evaluation period. It may be associated with the consistency of the implant and its stability at the injection site. Longer follow-up studies and human clinical investigations are required to consider CAM implantation as an alternative treatment for stress urinary incontinence.

Migración de catéter ureteral doble-J a vena cava inferior, una complicación inusual / Migration of double-J ureteral catheter into the inferior vena cava, an unusual complication

La colocación de catéteres ureterales doble-J es uno de los procedimientos más realizados en Urología, con bajas tasas de complicaciones graves. No obstante, pueden ocurrir y requieren de una identificación y tratamiento precoz. Presentamos el caso de un varón de 73 años intervenido de una prostatectomía radical, al que se le coloca un catéter doble-J por sospecha de lesión ureteral durante la intervención, con inestabilidad hemodinámica en el postoperatorio inmediato secundaria a la migración del catéter a la vena cava inferior

Double-J ureteral catheter placement is one of the most commonly performed procedures in Urology, with low rates of severe complications. Nevertheless, they can occur and require early identification and treatment. We present the case of a 73-year-old man who underwent radical prostatectomy and placement of a double-J catheter due to suspected ureteral injury during the surgery, with hemodynamic instability in the immediate postoperative period secondary to intracaval migration of the catheter.

Comparative analysis between open transvesical and laparoscopic adenomectomy in the treatment of benigne prostatic hyperplasia in a tertiary hospital in Curitiba-PR: a retrospective study / Análise comparativa entre adenomectomia transvesical aberta e videolaparoscópica no tratamento da hiperplasia prostática benigna em hospital terciário de Curitiba - PR: estudo retrospectivo

ABSTRACT Objective: the aim of this study was to compare the results of open and videolaparoscopic transvesical prostatectomy techniques in the treatment of benign prostatic hyperplasia (BPH) in a tertiary hospital. Methods: we reviewed medical records of patients who underwent transvesical adenectomy due to BPH between March 2019 and March 2021 at the urology service of Hospital de Clínicas do Paraná (HCPR), 42 patients were included in the open transvesical prostatectomy group and 22 in the videolaparoscopic group. Then, a comparison was made between the techniques in terms of surgical time, bleeding, length of stay, need for intensive care, among others, in addition to postoperative outcome. Results: the mean surgical time was shorter in the open technique compared to the laparoscopic technique (141 min vs 274 min). The videolaparoscopic group had a shorter mean hospital stay (3.5 days vs 6.36 days). There was no statistical significance in the comparison regarding the need for an intensive care unit, as well as in the assessment of postoperative bleeding. Conclusion: comparatively, the techniques demonstrated a similar outcome, with a low rate of complications and satisfactory results for the treatment of BPH. The laparoscopic technique is a surgery with a shorter hospital stay, but at the expense of a longer surgical time.

Quadratus Lumborum Block for Upper Tract Urological Surgery in Pediatric Patients / Bloqueo del cuadrado lumbar para cirugía urológica del tracto superior en pacientes pediátricos

Objective Among regional blocks, the quadratus lumborum fascial plane block (QLB) has been well described, but the description of its use and efficacy for pediatric patients undergoing upper abdominal urologic surgery is limited. We present a case series examining the use of the QLB for postoperative pain management in children undergoing upper tract surgery. Methods From August 2019 to August 2020, through a chart review, we identified 5 patients who had undergone a QLB for upper urinary tract surgery via a flank incision. Posterior QLB was performed after induction of general anesthesia. A single injection of 0.5mL/kg of either 0.25% or 0.5% ropivacaine with 1mcg/kg of clonidine was administered. Patients received fentanyl IV (1 mcg/kg), and acetaminophen IV (15mg/kg) as adjuvants during the operation. Postoperative pain was managed with oral acetaminophen and ibuprofen. Results The average postoperative pain score during the entire admission was 1, with the lowest being 0 and highest, 3. No administration of rescue narcotics was required in the postanesthesia care unit or on the floor. The average length of stay ranged from 0 to 1 day. No complications associated with the regional QLB were identified. Conclusions Our series suggests the QLB may be considered as a regional anesthetic option to minimize narcotic requirements for children undergoing upper abdominal urological surgery via flank incision. Additional studies are needed to compare the efficacy of the QLB versus alternate regional anesthetic blocks for upper tract urological surgery via flank incision in children and to determine effective dosing and use of adjuvants

Objetivo Entre los bloqueos regionales, el bloqueo del plano fascial del cuadrado lumbar (BCL) ha sido bien descrito; sin embargo, tiene una descripción limitada de su uso y eficacia en pacientes pediátricos sometidos a cirugía urológica abdominal superior. Presentamos una serie de casos que examinan el uso del BCL en el manejo del dolor posoperatorio en niños sometidos a cirugía urológica del tracto superior. Métodos De agosto de 2019 a agosto de 2020, mediante revisión de historias clínicas, se identificaron 5 pacientes sometidos al BCL para cirugía del tracto urinario superior por incisión en el flanco. El BCL posterior se realizó después de la inducción de la anestesia general. Solo se administró una inyección de 0,5 ml/kg de ropivacaína al 0,25% o al 0,5% con 1 mcg/kg de clonidina. Los pacientes recibieron fentanilo IV (1 mcg/kg) y acetaminofén IV (15 mg/kg) como adyuvantes durante la operación. El dolor posoperatorio se manejó con acetaminofén e ibuprofeno oral. Resultados El puntaje promedio de dolor posoperatorio para todo el ingreso fue de 1, siendo el más bajo 0 y el más alto, 3. No se requirieron administraciones de narcóticos de rescate en la unidad de recuperación posanestésica ni en la planta de hospitalización. La estancia media fue de 0 a 1 día. No se identificaron complicaciones asociadas con el BCL regional. Conclusiones Nuestra revisión sugiere que el BCL puede ser considerado una opción anestésica regional para minimizar los requerimientos de narcóticos en niños sometidos a cirugía urológica abdominal superior por incisión en el flanco. Se necesitan estudios adicionales para comparar la eficacia de BCL en comparación con la de los bloqueos anestésicos regionales alternativos para la cirugía urológica del tracto superior por incisión en el flanco en niños y para determinar la efectividad de la dosificación y del uso de adyuvantes.

Melanoma metastásico a vejiga / Metastatic melanoma to the bladder / Melanoma metastático na bexiga

Introducción. El compromiso tumoral metastásico del melanoma al tracto genitourinario es frecuente, pero, la metástasis a vejiga es rara, constituye menos del 2% de los casos. Sin embargo, en autopsias realizadas a pacientes con melanoma se ha encontrado metástasis en la vejiga en entre un 18% y un 37% de los casos, lo que la convierte en la segunda en incidencia posterior al adenocarcinoma gástrico. La media de supervivencia suele ser entre 6 - 7.5 meses. El objetivo de este trabajo es presentar el caso de un melanoma metastásico a vejiga, entidad poco frecuente y poco diagnosticada por ser la mayoría de las veces asintomática. Presentación del caso. Paciente femenina de 62 años, con antecedente de melanoma al nivel del primer artejo del pie, con manejo quirúrgico y farmacológico. Consultó por hematuria. La cistoscopia evidenció una lesión única sólida, eritematosa, con necrosis y fácil sangrado y se indicó realizar resección transuretral (RTU). La patología demostró compromiso por melanoma ulcerado metastásico. Se inició manejo de segunda línea (Pembrolizumab) y presentó progresión a miembros superiores y recaída a nivel vesical. La paciente falleció un año después. Discusión. Las metástasis de melanoma al tracto genitourinario son frecuentes, pero las metástasis vesicales aisladas son raras. El tratamiento suele ser RTU de la lesión, cistectomía, quimioterapia y radioterapia. La RTU es curativa para las lesiones restringidas al epitelio, aunque la cistectomía radical suele ser la terapia de elección ante un paciente con un tumor localizado. El Pembrolizumab ha demostrado aumentar la supervivencia. El pronóstico depende del tamaño y profundidad de la invasión. Conclusiones. El compromiso vesical metastásico es poco frecuente y diagnosticado, puede estar presente en pacientes con melanoma, síntomas irritativos urinarios no específicos y hematuria. Suele ser de mal pronóstico, y requiere de manejo quirúrgico asociado a manejo sistémico.

Introduction. Metastatic tumor compromise of melanoma to the genitourinary tract is frequent, but metastasis to the bladder is rare, representing less than 2% of cases. However, autopsies performed on patients with melanoma have found metastases in the bladder in 18-37% of cases, making it the second incidence after gastric adenocarcinoma. The median survival is usually 6 to 7.5 months. The objective of this work is to present the case of a metastatic melanoma to the bladder, a rare and underdiagnosed condition because most of the time it is asymptomatic. Case Presentation. 62-year-old female patient, with a history of melanoma at the level of the first toe, with surgical and pharmacological management. The reason for consultation was hematuria. Cystoscopy revealed a single solid, erythematous lesion with necrosis and easy bleeding, and a transurethral resection (TUR) was indicated. The pathology found compromise for metastatic ulcerated melanoma. Second-line treatment (Pembrolizumab) was started and presented progression to the upper limbs and relapse at the bladder level. The patient died a year later. Discussion. Melanoma metastases to the genitourinary tract are common, but isolated bladder metastases are rare. Treatment is usually TUR of the lesion, cystectomy, chemotherapy, and radiation therapy. TUR is curative for lesions restricted to the epithelium, although radical cystectomy is usually the therapy of choice in patients with a localized tumor. Pembrolizumab has been shown to increase survival. The prognosis depends on the size and depth of the invasion. Conclusions. Metastatic bladder compromise is rare and underdiagnosed, it may be present in patients with melanoma, non-specific urinary irritative symptoms, and hematuria. It tends to have a poor prognosis, and requires surgical management associated with systemic management.

O objetivo deste trabalho é apresentar o caso de um melanoma metastático na bexiga, uma entidade pouco frequente e subdiagnosticada, pois na maioria das vezes é assintomática. Apresentação do caso. Paciente do sexo feminino, 62 anos, com antecedentes de melanoma no nível do hálux, com manejo cirúrgico e farmacológico. Ela consultou por hematúria. A cistoscopia revelou uma única lesão sólida, eritematosa com necrose e sangramento fácil, e foi indicada uma ressecção transuretral (RTU). A patologia mostrou comprometimento de melanoma ulceroso metastático. O tratamento de segunda linha (Pembrolizumab) foi iniciado e a patologia avançou para os membros superiores e uma recaída no nível da bexiga. A paciente morreu um ano depois. Discussão. As metástases de melanoma para o trato geniturinário são frequentes, mas as metástases vesicais isoladas são raras. O tratamento é geralmente RTU da lesão, cistectomia, quimioterapia e radioterapia. A RTU é curativa para lesões restritas ao epitélio, embora a cistectomia radical seja geralmente a terapia de escolha para um paciente com um tumor localizado. O Pembrolizumab demonstrou aumentar a sobrevivência. O prognóstico depende do tamanho e da profundidade da invasão. Conclusões. O comprometimento vesical metastático é raro e subdiagnosticado, pode estar presente em pacientes com melanoma, sintomas irritantes urinários não específicos e hematúria. Geralmente tem um prognóstico negativo e requer manejo cirúrgico em associação com manejo sistêmico.

Disfunción sexual femenina: una mirada a los últimos 44 años. Análisis bibliométrico / Female Sexual Dysfunction: Looking Back at the Last 44 Years. A Bibliometric Analysis

Objetivo La disfunción sexual femenina (DSF) es un trastorno prevalente que afecta la calidad de vida de las mujeres y combina factores biológicos, psicológicos e interpersonales. Su estudio ha sido de poco interés, en campos como la investigación y el tratamiento, debido a la dificultad en la medición de las respuestas sexuales en las mujeres y otros factores, como el tabú acerca de la sexualidad femenina. Este estudio caracteriza las tendencias de publicaciones científicas acerca del tema, para que los urólogos puedan comprender la necesidad de realizar la búsqueda de este trastorno en la práctica diaria. Métodos Se realizó una búsqueda de la literatura en las bases de datos PubMed, FABUMED y Scopus, utilizando la estrategia «((«female sexual dysfunction¼ [Title/Abstract])¼. Se realizó un análisis bibliométrico descriptivo, de corte retrospectivo, de la literatura médica obtenida en MEDLINE. A través de las herramientas estadísticas FABUMED, PubReminer y Scopus, se recopilaron los datos y se obtuvo los resultados de las variables que posteriormente fueron analizadas de forma estadística y descriptiva. Con base en esta información, elaboramos tablas y gráficas en Microsoft Office Excel 2017. Adicionalmente, realizamos un análisis de mapeo bibliométrico utilizando el programa VOSviewer. Para la obtención del factor de impacto (FI), utilizamos el Journal Citation Reports 2017/2018. Resultados Desde 1975 hasta 2019, se publicaron 1.292 estudios, y la tasa anual de publicación permaneció estable entre 1975 y 2000. Pero, a partir del año 2000, se evidenció un aumento en el número de publicaciones, con un crecimiento del 92,1%. De las veinte revistas con más publicaciones, sólo cuatro son de urología. Los países con más publicaciones fueron: Estados Unidos (31,4%), Reino Unido (12,9%), Italia (8,9%), Turquía (5,9%), y Australia (4%). Estos datos son muy diferentes a los de los países de América Latina, en los que se encontraron muy pocas publicaciones, como Colombia, con tan sólo tres estudios. Conclusiones Este análisis bibliométrico mostró las diferentes tendencias y tasas de publicación de estudios sobre DSF, y evidenció una baja tasa de producción con relación a otras temáticas, sobre todo en las revistas urológicas, con predominio de mujeres como autores, aunque en los últimos años se ha identificado un crecimiento importante y sostenido. Se hace evidente la necesidad de desarrollar estrategias para mejorar la formación tanto en los niveles de posgrado como de pregrado y, así, generar más adhesión a este tema en una especialidad quirúrgica como la nuestra.

Objectives Female sexual dysfunction (FSD) is a prevalent disorder that affects the quality of life of women and combines biological, psychological, and interpersonal factors. There has been a lack of interest in studying FSD in such fields as research and treatment, due to the difficulty in measuring the sexual responses of women and other factors such as the taboo surrounding female sexuality. The present study portrays the trends in the scientific publications on the subject, so urologists can perceive and understand the need for research about this disorder in the daily practice. Methods A comprehensive review on the topic was performed through a PubMed, FABUMED, and Scopus databases using the search strategy "female sexual dysfunction", as well as a retrospective, descriptive, bibliometric analysis of the medical literature retrieved from MEDLINE. Data was collected through the FABUMED, PubReMiner, and Scopus statistical tools, and, based on the results obtained for the variables, which were later submitted to a statistical and descriptive analysis. Based on this data, tables and graphs were developed using the Microsoft Office Excel 2017 software. Moreover, we performed a bibliometric mapping analysis using the VOSviewer software. In order to obtain the impact factor (IF), we used the Journal Citation Reports 2017/2018. Results From 1975 to 2019, 1,292 studies were published; yearly publication rate remained stable from1975 to 2000, but after year 2000, an increase in the number of publications was evidenced, with a growth of 92.1%. But as of the year 2000, an increase in the number of publications was evidenced, with a growth of 92.1%. Of the twenty journals with the most publications, only four are on urology. The countries with the greatest number of publications were: the United States (31.4%), the United Kingdom (12.9%), Italy (8.9%), Turkey (5.9%), and Australia (4%). This data differs from that of Latin American countries, in which few publications were found, such as in Colombia, with only three studies. Conclusions The present bibliometric analysis showed the different trends and publication rates of studies on FSD, showing a low production rate as compared with that of other urological topics, especially in Urological journals, with a predominance of women as authors, although in recent years an important and sustained growth has been identified. The need to develop strategies to improve training at both the graduate and undergraduate levels and thus generate more adherence to these issues in a surgical specialty like ours is evident.

Percepción de acoso o discriminación durante la residencia de urología en Colombia / Perception of Harrasment or Discrimination during Urology Residency in Colombia

Objetivos El maltrato laboral (acoso, abuso o discriminación) ejercido de manera persistente contra un individuo genera un ambiente de trabajo hostil y lleva a agotamiento, con un impacto psicológico importante y la posibilidad de aparición de síntomas depresivos. En Colombia, no contamos con publicaciones al respecto. El objetivo de nuestro trabajo es conocer la percepción de los residentes de urología en cuanto a discriminación de género y acoso laboral, verbal y sexual durante su formación. Metodos Estudio observacional, descriptivo, de corte transversal, por medio de encuestas anónimas. Evaluamos las características demográficas, la percepción de acoso, el tipo de acoso, si éste afectó el rendimiento laboral del residente, y por parte de quién lo percibió. Resultados Obtuvimos respuestas de 82/115 (71,3%) residentes, en su mayoría hombres (45 [56%]). En total, 66% (54) reportaron haber experimentado acoso laboral; y 35,4% (29) reportaron haber experimentado discriminación de género, siendo más frecuente en las mujeres (17; 58,6%). El acoso verbal fue reportado por un 64,6% (53), y afectó el trabajo de un 92,5%. La percepción de acoso laboral fue similar entre hombres y mujeres (32 [69.5%] hombres y 21 [61.1%] de mujeres). En total, 7 (19%) mujeres reportaron acoso sexual. Con respecto a la fuente de acoso, 39 (65,8%) fue por profesores, 26 (45%), por otros residentes, y 17 (35.4%), por pacientes. Conclusión La percepción de acoso durante la residencia de urología en Colombia es real, y afecta el trabajo de los residentes. Este acoso es mayor por parte de los hombres, y es principalmente generado por profesores. Consideramos nuestro trabajo el punto de partida para continuar investigando un tema de importancia a nivel nacional y internacional.

Purpose Workplace bullying (harassment, abuse, or discrimination), practiced persistently against an individual, can generate a hostile workplace environment, consequently leading to exhaustion, with poor psychological outcomes, and the onset of symptoms such as loss of confidence, fatigue, depressive thoughts, desertion, and suicidal thoughts. There are no publications regarding this issue in Colombia. Our objective is to describe the residents' perception of gender and workplace discrimination and verbal/sexual harassment during their urological training. Methods Observational, descriptive, cross-sectional study with anonymous surveys. We evaluated the demographic characteristics and the residents' perception of harassment, the type of harassment, how it affected their performance during residency, and from whom it was perceived. Results We were able to obtain answers from 82/115 residents (71.3%), most of them men (45 [56%]). In total, 66% (54) reported workplace harassment; and 35.4% (29) felt gender discrimination, most of them women (17; 58.6%). Verbal abuse was reported by 64.6% (53), and it affected the work of 92.5%. The paerception of workplace harassment was similar among both men and women (32 [69.5%] men and 21 [61.1%] women). A total of 7(19%) women reported sexual abuse. Regarding the source of the abuse, 39 (65.8%) was by professors, 26 (45%), by other residents, and 17 (35.4%), by patients. Conclusion The perception of harassment during urology residency in Colombia is real, and it affects the work of residents. This abuse is greater on the part of men, and is mainly perpetrated by professors. We consider our work the starting point to continue researching a topic of national and international importance.
