Experiences and Outcomes of the Society of Genitourinary Reconstructive Surgeons Fellowship Training: Growth in Fellowships Mirrors the Evolution of the Discipline.

OBJECTIVE: To describe experiences and outcomes of the Society of Genitourinary Reconstructive Surgeons (GURS) fellowship match. In 2012, GURS developed a centralized fellowship match which has grown from 13 to 30 programs. METHODS: GURS match statistics and case logs were reviewed from 2013-2024. Additionally, a 37-question survey evaluating satisfaction, procedural competency, fellowship experience, and employment opportunities were sent to graduates. Linear regression was performed to examine trends over time. RESULTS: Over the study period, program match success remained stable (94.7%; P = .50) while applicant success (63.3%) increased over time (P = .04). North American and female applicants experienced higher match success (72.8% and 73.6%) compared to their international (35.5%; P <.0001) and male counterparts (60.0%; P = .02). On case log analysis, mean surgical volumes per year increased in urethral reconstruction (mean=88.1; P = .02), male sexual health (n = 32.7; P = .03), genital reconstruction (mean=16.4; P <.01) and abdominal reconstruction (mean=24.5; P = .03). Male incontinence surgeries remained stable (mean=30.5; P = .21) while female reconstruction declined (mean=23.2; P = .01). With a survey response rate of 54.5% (97/178), training satisfaction was 95.9% which did not differ by gender (P = .54) or year of training (P = .22). Around 97.9% felt competent to enter unsupervised reconstructive practice, 94.8% reported an understanding of the relevant literature and 96.9% were satisfied with their job as a reconstructive urologist. Around 49.5% identified a different case mix in practice compared to fellowship, most commonly related to abdominal (44.9%) or genital reconstruction (16.3%). CONCLUSION: GURS fellowships have grown organically over the last decade and mirror the growth and evolution of the discipline with sustained high levels of graduate satisfaction, surgical experience, competence, scholarly inquiry and employment.

Refining Bacteriuria as a Risk Factor for Complications After Urethroplasty: Identifying the Culprit.

OBJECTIVE: To determine which bacteria are associated with an increased risk of 90-day complications after urethroplasty. Preoperative bacteriuria is associated with an increased risk of complications after urethroplasty. However, it remains unclear which specific micro-organisms are the primary drivers of this morbidity. METHODS: A single-institution, 2-surgeon retrospective review was performed on patients undergoing urethroplasty from 08/2003 to 06/2021. Preoperative bacteriuria was considered significant when the patient had a mixed culture with ≥108 CFU/L or an identifiable micro-organism with ≥106 CFU/L. Descriptive statistics were used to summarize the results and chi-square was used to determine the association between 90-day complications (Clavien ≥2) and clinical characteristics/bacteria. RESULTS: Out of 1611 patients, 23.2% (373) had significant preoperative bacteriuria. The most common pathogens included coagulase-negative staphylococcus 18.5% (69), mixed growth 15.8% (59), Escherichia coli 10.7% (40), and Enterococcus 14.2% (53). 7.9% (128/1611) experienced a significant 90-day complication (Clavien-Dindo ≥2). Gram-negative bacilli including E coli, Pseudomonas sp, Klebsiella sp, Serratia sp, Citrobacter sp, Achromobacter sp, Stenotrophomonas sp, and Morganella sp were associated with higher rates of postoperative complications (14.2%; P = .01) as well as Enterococcus sp (15.1%; P = .03). However, gram-positive cocci (7.9%; P = .97), gram-positive bacilli (11.8%; P = .47), mixed growth (5.1%; P = .54) and Candida (16.7%; P = .27) were not. Neither escalating concentrations of bacteria (P = .44) or number of strains (P = .08) were associated with increased risk of complications. CONCLUSION: The main driver of bacteriuria-related complications after urethroplasty are gram-negative bacilli and Enterococcus sp. Patients with bacteriuria related to other micro-organisms can likely proceed with urethroplasty without increased risk of postoperative complications.

Routine Imaging After Bulbar Urethral Reconstruction Does Not Impact Surgical Outcomes and May Not Be Necessary.

OBJECTIVE: To assess whether omitting routine post-operative imaging adversely impacts clinical outcomes after bulbar urethroplasty. Contrast imaging is commonly performed prior to catheter removal after urethroplasty but the clinical need for this is unclear. METHODS: This was a matched, case-control analysis comparing patients undergoing routine voiding cystourethrogram (VCUG) prior to catheter removal after bulbar urethroplasty to patients without imaging. Patients were matched with respect to age, stricture etiology, length, and urethroplasty technique. Follow-up consisted of clinical assessment 3 weeks post-operatively for VCUG/catheter removal, cystoscopy at 3-4 months with clinical assessment annually. Outcome measures were 90-day complications (Clavien ≥2) and stricture recurrence (failure to pass a 16-Fr flexible cystoscope on follow-up). Chi-square and Kaplan-Meier analysis were conducted where appropriate. RESULTS: Hundred patients undergoing bulbar urethroplasty with VCUG prior to catheter removal were compared to 100 matched case controls without imaging. Groups did not differ with respect to failed endoscopic treatment (P = .82), prior urethroplasty (P = .09), comorbidities (P = .54), smoking (P = .42), or pre-operative bacteriuria (P = 1.00). The incidence of extravasation in the VCUG group was 2%. Overall 90-day complications were 9.5% and 15 patients developed recurrence with a median follow-up of 174 months. On chi-square analysis, 90-day complications did not differ between patients undergoing VCUG and those without (12% vs 7.0%; P = .34). On log-rank analysis, stricture recurrence did not differ between groups (P = .44). CONCLUSION: Routine imaging with VCUG after bulbar urethroplasty does not influence the risk of post-operative complications or stricture recurrence. Surgeons should consider avoiding this potentially unnecessary examination in routine clinical practice.

Defining bladder outlet obstruction and detrusor underactivity in females with overactive bladder: Are we forgetting about the free uroflowmetry?

INTRODUCTION: Both detrusor underactivity (DU) and bladder outlet obstruction (BOO) can coexist in patients with overactive bladder. Definitions of both DU and BOO are based on pressure-flow study (PFS) data. However, invasive urodynamics study can differ from a natural micturition, in fact, discrepancies between free uroflowmetry (UFM) and PFS have been largely described. Our goal is to assess the correlation of free-flowmetry and PFS among patients with OAB and to evaluate how different definitions of DU/BOO are able to discriminate patients with different free UFMs. METHODS: A retrospective review of urodynamics performed at a single institution was conducted. Females with OAB who voided more than 150 mL in both UFM and PFS were included. Parameters from both voiding episodes were compared with nonparametric test. Two definitions of DU were applied; PIP1: Pdet@Qmax+Qmax < 30 and Gammie: Pdet@Qmax < 20 cmH2 O, Qmax < 15 mL/s, and BVE < 90% (Bladder voiding efficiency). Also, two definitions of obstruction were chosen; Defretias: Pdet@Qmax ≥25 cmH2 O and Qmax ≤ 12 mL/s and Solomon-Greenwell female BOO index ≥ 18. Patients who matched with each definition were compared to those who did not, to assess if any definitions were able to discriminate different noninvasive uroflowmetries. RESULTS: A total of 195 patients were included. Overall, mean age was 55 ± 12 years, 90.8% had mixed urinary incontinence, and 39% complained of at least one voiding symptom. Globally, Qmax and BVE correlated poorly between UFM and PFS, showing that most of the variation corresponded to a systematic error. Twenty-two individuals were found to have DU, they had a difference of 13 mL/s on both maximum flows. Fifty-four patients showed BOO, with a difference between their Qmax of 19 mL/s. Among the four definitions analyzed, only PIP1 and Defreitas were able to discriminate patients with actually a lower Qmax on the free UFM. CONCLUSIONS: Patients with overactive bladder seem to have a systematic discordance between the urine flow of the free and invasive studies. Current definitions of DU and BOO, which are based on the PFS parameters, are not consistently able to discriminate patients who actually void deficiently on the free UFM.

De las prácticas de educación indígena en el Ecuador a la noción de interculturalidad / From the Practices of Indigenous Education in Ecuador to the Notion of Interculturality

Resumen Son los Pueblos Indígenas y sus luchas quienes han venido dando carácter a la noción de interculturalidad. Y es el campo de la educación un escenario en el que la interculturalidad ha emergido y se ha labrado. Hay experiencias de educación de los Pueblos Indígenas que se han planteado como alternativas de superación de la colonialidad. La lucha del movimiento indígena, al lado de estas experiencias, ha venido configurando una plataforma de confrontación que permite presentarle a los Estados, en el caso concreto de Ecuador a los gobiernos y a la población, desafíos en torno a la comprensión de la nación y del carácter de la misma y de la educación y del carácter de la misma igualmente.

Abstract It is the Indigenous Peoples and their struggles who have been giving character to the notion of interculturality. And the field of education is a scenario in which interculturality has emerged and has been carved. There are experiences of education of Indigenous Peoples that have been proposed as alternatives for overcoming coloniality. The struggle of the indigenous movement, alongside these experiences, has been configuring a platform of confrontation, which allows presenting the States, in the specific case of Ecuador, the governments and the population, with challenges regarding the understanding of the nation and its character, and of education and its character, as well.

Dropped abdominal pressure at void in women.

INTRODUCTION AND HYPOTHESIS: "Dropped pabd at void" occurs when pabd decreases below the previous resting pressure during voiding time. We sought clinical factors associated with this phenomenon and evaluated whether its correction modifies the urodynamic diagnosis. METHODS: Retrospective cross-sectional study of non-neurological consecutive symptomatic women. The following definitions were used: "dropped pabd at void": decrease in pabd at Qmax ≥ 5 cmH2O; bladder outflow obstruction (BOO) (pdetQmax ≥ 25 cmH2O + Qmax ≤ 12 ml/s and female BOO index (pdetQmax - 2.2*Qmax) > 18; "low detrusor contraction strength": PIP1 (pdetQmax + Qmax) < 30. In patients with "dropped pabd at void", pdetQmax was corrected. RESULTS: A total of 360 women were analyzed. Ninety-five percent of the women had a variation in pabd at Qmax between -13 and 53 cmH2O. "Dropped pabd at void" was found in 100 women (27.8%). History of stress urinary incontinence (SUI) surgery was significantly higher (p = 0.016) and symptoms of mixed urinary incontinence were significantly lower (p = 0.030) in patients with "dropped pabd at void". On multivariate analysis only the history of SUI surgery maintained its significance (OR = 1.787 [95% CI: 1.058, 3.017], p = 0.030). When correcting pdetQmax in women with "dropped pabd at void", 2 or 5 patients lost BOO diagnosis (depending on how it was diagnosed) and 7 patients gained a "low detrusor contraction strength" diagnosis. CONCLUSIONS: Approximately one-quarter of women had "dropped pabd at void", which was associated with a history of SUI surgery. Correction of pdetQmax would lead to a 2.5% to 3.33% diagnostic modification.

Urodynamic and clinical features in women with overactive bladder: When to suspect concomitant voiding dysfunction?

AIM: The aim of this study is to describe the prevalence and type of female voiding dysfunction (FVD) in patients with overactive bladder (OAB) who were studied by urodynamics and its relationship with voiding symptoms. METHODS: This is a cross-sectional study of female adult patients with OAB syndrome who underwent UDS in a University Hospital in Chile between January 2015 and April 2020. FVD was defined either as bladder outlet obstruction (BOO) or detrusor underactivity (DU). BOO was established if the Solomon-Greenwell BOO index was higher than 18. DU was diagnosed when the invasive maximum flow rate (Qmax) was ≤15 ml/sec, detrusor pressure at Qmax (Pdet@Qmax) was ≤20 cmH2 O and postvoid residual (PVR) was greater than 10%. Urodynamic data and clinical features were compared between groups. RESULTS: Two hundred and ninety-nine UDS were selected and analyzed. Bladder outlet obstruction was diagnosed in 59 patients (19.7%), whereas DU was found in 10 patients (3.3%). In the multivariate analysis, the logistic regression to predict BOO demonstrated that night-time frequency, the presence of detrusor overactivity and a higher PVR were independent predictors of BOO. Instead, for DU, the only independent predictor was a smaller voided volume in the pressure-flow study. CONCLUSION: Female voiding dysfunction was found in 23% of patients with overactive bladder. BOO is more frequent than DU, and should be suspected in patients with higher night-time frequency, presence of detrusor overactivity and a high PVR. Instead, DU should be suspected in patients with a smaller voided volume.

Abordaje y manejo del infarto agudo miocardio con elevación del ST en Costa Rica durante la pandemia por COVID-19 Documento de consenso de la Asociación Costarricense de Cardiología / Approach and management of acute ST elevation myocardial infarction in Costa Rica during the COVID-19 pandemic Consensus document of the Costa Rican Association of Cardiology

Resumen El virus SARS-CoV-2 se ha extendido a nivel mundial, rápidamente ha sobrecargado los sistemas de salud. Esta emergencia ha implicado cambios en la atención usual del infarto agudo miocardio con elevación del ST (IAMCEST) puesto que la actividad habitual de las salas de hemodinamia y las vías de traslado de los pacientes se ha visto afectada. La afectación del personal de salud también es una preocupación relevante por lo que presentamos un documento de Consenso de la Asociación Costarricense de Cardiología que pretende generar una guía de trabajo al personal que atiende esta patología y garantizar la atención adecuada del IAMCEST durante la pandemia en Costa Rica.

Abstract The current COVID-19 has spread worldwide, the outbreak is altering the usual activity of the catheterization laboratorios and the usual treatment pathways of patients with chronic diseases or emergencies, such as Acute Coronary Syndrome could be disrupted. The involvement of health personnel is a relevant concern, so we created a consensus document of the Costa Rican Association of Cardiology that aims to generate a decision-making workflow to treat this pathology and guarantee adequate and continuous care for ST elevation myocardial infarction during the COVID-19 outbreak.

Reestructuración del abordaje de la patología estructural cardiaca en tiempos de pandemia por COVID-19 / Restructuring of the approach to structural pathology Cardiac in times of pandemic by COVID-19

Resumen La red sanitaria en el entorno de la pandemia por COVID-19 ha sufrido un gran impacto. La reorganización de la misma ha sido fundamental para poder atender la emergencia sanitaria, y en algunos países, ha sido incluso de forma abrupta. La atención oportuna de las enfermedades cardiovasculares continúa siendo una prioridad por la elevada mortalidad que ella implica especialmente en estadios muy avanzados de la enfermedad, y la modificación en la atención médica en el contexto actual no puede afectar la asistencia de patologías cardíacas. Los programas de cardiología estructural y cirugía cardíaca en nuestro país se han consolidado y crecido en los últimos años, ofreciendo múltiples procedimientos percutáneos o mínimamente invasivos para cardiopatías de alta morbimortalidad. La continuación de los mismos, a pesar de las dificultades por la pandemia, es necesaria en ciertos casos. Este documento reúne las principales recomendaciones basados en textos internacionales al respecto, para mantener el cuidado cardiovascular en Costa Rica pese al COVID-19 en el ámbito de la cardiopatía estructural.

Abstract The health system in the context of the COVID-19 pandemic has suffered a great impact. Thus, organization has been essential in maintaining the ability to respond to the health emergency, and in some countries, it has even been abrupt. The treatment of cardiovascular diseases continues to be a priority, and the modification of medical care in the current context cannot affect the timely procedures of cardiac pathologies. The structural cardiology and cardiac surgery programs in our country have been consolidated and grown in recent years, offering multiple percutaneous or minimally invasive procedures for heart disease with high morbidity and mortality. Their continuation, despite the difficulties caused by the outbreak, is necessary in certain cases. This document brings together the main recommendations based on international guidelines and experts opinions in this regard, to maintain cardiovascular care in Costa Rica despite COVID-19.

[Usefulness of imaging studies in prostate cancer: Analysis of 241 patients]. / ¿Es necesario realizar un estudio de etapificación en todos los pacientes con cáncer de próstata?: Experiencia de un centro clínico nacional.

BACKGROUND: The role of staging studies in patients with prostate cancer (PCa) is a topic of discussion. AIM: To evaluate the usefulness of imaging studies in patients with prostate cancer. MATERIAL AND METHODS: We reviewed the pathology service records to identify patients with prostate cancer diagnosed between 2003 and 2013. We reviewed the electronic medical records of those patients identified as having a prostate cancer. Patients were grouped according D’amico’s classification of cancer dissemination risk. We analized the frequency of imaging studies requested and their efficacy to detect metastases in each risk group. RESULTS: We identified 241 patients with a mean age of 67 years. Fifty two percent of patients were classified as low-risk, 32% as intermediate-risk and 16% as high risk. At least one imaging study was requested to 64% of patients (49, 78 and 87% of patients with low, intermediate and high risk respectively). Among the 155 patients in whom an imaging study was requested, no metastases were found in the low risk group. On the other hand, dissemination was found in 7% of the intermediate-risk group and 62% of the high-risk group. CONCLUSIONS: Half of patients with prostate cancer were classified as low risk. In half of this group of low risk patients, staging studies were requested and the probability of detecting metastases was low or nil. The odds of detecting metastases increased in higher risk groups.

Evaluation of a systematic approach to pediatric back pain: the utility of magnetic resonance imaging.

BACKGROUND: Several studies have suggested that back pain in the majority of pediatric patients does not have an identifiable cause. Many children undergo extensive diagnostic workup that ultimately results in a nonconfirmative diagnosis. The purpose of this study was to (1) describe the prevalence of back pain seen in a pediatric orthopaedic clinic; (2) evaluate the efficacy of a systematic approach dependent on magnetic resonance imaging (MRI) in the diagnosis of pediatric back pain; and (3) analyze sensitivity, specificity, positive predictive value, and negative predictive value of various clinical signs and symptoms. METHODS: For a 24-month period, all patients that presented with a chief complaint of back pain were prospectively enrolled in this study and evaluated in a systematic approach which utilized MRI for patients with constant pain, night pain, radicular pain, or abnormal neurological examination after an initial history, physical examination, and negative radiographic examination. RESULTS: The prevalence of chief complaint of back pain was 8.6% (261/3042 patients). Of the 261 patients, 34% had an identifiable pathology following the systematic approach. In 8.8% of patients, the diagnosis was established with the history, physical examination, and plain radiographs. MRI yielded a definitive diagnosis in another 25% of patients. It is noteworthy that of the 89 patients with a confirmed pathology, 26% were identified with plain radiographs and 74% with MRI. CONCLUSIONS: A systematic approach to diagnose pediatric back pain demonstrated that 34% of pediatric patients that present to an outpatient orthopaedic clinic complaining of back pain will have identifiable pathology. The diagnostic yield increased from 8.8% with the history, physical examination, and plain radiographs to 22% with the TCN Bone Scan to 36% with the use of the MRI. The clinician should be aware that the presences of lumbar pain or constant pain are red flags for the presence of underlying pathology. LEVEL OF EVIDENCE: Level III.

[Prevalence of metabolic syndrome in Mapuche individuals living in urban and rural environment in Chile]. / Prevalencia de síndrome metabólico en individuos de etnia Mapuche residentes en zonas rurales y urbanas de Chile.

BACKGROUND: Metabolic Syndrome (MS) increases the risk of diabetes and mortality associated with cardiovascular disease. However, the prevalence of MS could differ by ethnicity and lifestyle factors. AIM: To determine the prevalence of MS in Mapuche individuals living in urban and rural environments in Chile and to investigate whether the prevalence and risk of MS in urban and rural environments differs by sex, age and nutritional status. MATERIAL AND METHODS: A total of 1077 Mapuche participants were recruited from urban (MU = 288) and rural (MR = 789) settings. Body mass index, waist circumference and blood pressure were measured. A fasting blood sample was obtained to measure serum glucose, HDL cholesterol and triacylglycerol. The prevalence of MS was determined using the unified IDF and ATP-III criteria. RESULTS: An environment and sex interaction was found for the prevalence of MS (p = 0.042). The prevalence was significantly lower in male MR (13%) compared to other groups (22, 23 and 25% among female MR, female MU and male MU respectively). Also, the prevalence of central obesity and low HDL-cholesterol were significantly lower in male MR. MU are at an increased risk of developing MS compared to MR, with an odds ratio of 1.59 (95% confidence intervals 1.1 to 2.2). This risk increases along with age or body mass index of the population. CONCLUSIONS: The adoption of an urbanized lifestyle increases the risk of developing MS in Mapuche individuals. This risk is enhanced by age and nutritional status.

Miocardiopatía tipo takotsubo / Takotsubo cardiomyopathy type

La miocardiopatía adquirida de tipo Takotsubo ha sido descrita desde 1991 en pacientes del género femenino, post menopáusica, quienes posterior a un evento estresante físico o psicológico asocian clínica de dolor precordial, con cambios electrocardiográficos, alteraciones transitorias de contractilidad de predominio anteroapical del ventrículo izquierdo (VI) y elevación de los biomarcadores cardiacos, en ausencia de una enfermedad arterial coronaria (EAC) aguda como mecanismo desencadenante del cuadro. La fisiopatología no ha sido completamente dilucidada pero existe consenso sobre la acción tóxica de las catecolaminas sobre el miocardio. El pronóstico es variable y va desde dolor, insuficiencia cardiaca, choque cardiogénico hasta, la muerte; por lo tanto, constituye un desafío en el diagnóstico diferencial de las causas no ateroescleróticas generadoras de un síndrome coronario agudo (SCA).

Tako-Tsubo cardiomiopathy was described in 1991 on mainly female postmenopause patients, with a previous physicalo psicological stress situation, whom presented with chest pain symptoms and ECG changes, transitorial contractilityalterations, mainly anteroapical on the left ventricle and cardiac biomarkers elevations; all this without any atheroscleroticcoronary heart disease as the cause of the disease presentation. The physiopathology of the disease has not beencompletely ellucidated , but there is an actual consensus about the toxic effect of catecholamines on the myocardium,with a variable prognosis from only chest pain, heart failure, cardiogenic shock and even death. That is why the diseaseis an actual challenge on the differential diagnosis of non atherosclerotic acute coronary síndromes.

[Crigler-Najjar syndrome. Report of one case with a long term follow up]. / Evolución prolongada en síndrome de Crigler-Najjar tipo I.

Crigler-Najjar Syndrome is an uncommon genetic disorder characterized by the elevation of unconjugated plasmatic bilirubin secondary to deficiency of the enzyme uridine diphosphate glucuronyltransferase (UDP-GT). We report a 19-years-old woman with the syndrome diagnosed during the neonatal period, when she developed a severe jaundice in the first 10 days of life, reaching unconjugated bilirubin levels of 29 mg/dl, with normal liver function tests. After transient response to phototherapy, the patient was referred to a tertiary medical center in which an extensive work up ruled out other etiologies and the diagnosis of type I Crigler-Najjar syndrome was established. Currently, the patient has a mild mental retardation. She is receiving homemade phototherapy 18 h per day with acceptable control of bilirubin levels. Many mutations have been associated with UDP-GT dysfunction resulting in a broad spectrum of the disease. When bilirubin rises above physiological limits, it permeates the hematoencephalic barrier, inducing bilirubin impregnation of basal ganglia with secondary neuronal damage and necrosis. The worst outcome, kernicterus, is characterized by mental retardation, central deafness, ophthalmoplegia, ataxia, athetosis, spasticity, seizures and death. First line therapy includes phototherapy, but definitive therapy is liver transplantation before the occurrence of neurological damage.

Conocimiento etnobotanico tradicional y uso de plantas Medicinales en un area rural de la Región Metropolitana de Chile: estudio descriptivo / Traditional ethnobotanical knowledge and use of medicinal plants in a rural area of the metropolitan region of Chile: descriptive study

Con el fin de caracterizar y evaluar el conocimiento botánico perteneciente a la población en el área rural (poco abordado por la etnobotánica) se realizó un estudio a través de encuestas para aprender sobre plantas medicinales cultivadas y utilizadas en una zona rural de la Región Metropolitana (San Juan de Pirque). Las conclusiones son que los usuarios tienen un conocimiento híbrido (producto de los conocimientos tradicionales en combinación con la información de diversos tipos) de plantas medicinales. Hemos encontrado que la mayoría de las especies cultivadas en los jardines botánicos fueron especies introducidas y muy pocos las nativas. También, se les conocía por sus nombres comunes y no se detectaron nuevos nombres no descrito previamente en la literatura.
