RESUMO
Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.
Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.
Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas. Isso aumenta o risco de complicações relacionadas ao seu uso, portanto, podem ser evitáveis. O objetivo deste estudo é conhecer as características do uso do cateterismo urinário em pacientes internados em enfermarias de cuidados moderados de um hospital universitário terciário, determinar a frequência, duração e indicações mais frequentes, bem como avaliar a presença de complicações associadas ao mesmo. Metodologia: Estudo transversal, realizado em quartos de cuidados moderados de um hospital terciário e universitário em Montevidéu, Uruguai, em 21 de dezembro de 2022. Foram incluídos pacientes que apresentaram ou apresentaram sonda vesical durante a internação atual e a coleta de variáveis ââfoi concluída .revisando o histórico médico. Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.
RESUMO
Resumo O cateter vesical de longa permanência pode ser indicado em situações clínicas, como nas doenças crônicas do sistema genitourinário ou neurológico. Além dos riscos de infecção, traumas e sangramentos, a permanência do cateter pode afetar dimensões psicoemocionais e socioeconômicas. Objetivamos compreender como a necessidade de uso do cateter urinário por um longo prazo afeta a autopercepção, as interrelações e o autocuidado deste paciente. Realizamos um estudo qualitativo, descritivo, a partir da entrevista de 17 pacientes, e aplicamos a análise temática e o pensamento complexo. Os diferentes prognósticos e as expectativas em relação ao cateter influenciaram a autopercepção, a adaptação, sua aceitação ou negação. A presença do cateter, seja como medida curativa ou para conforto, pode afetar a autoimagem e a sexualidade, gerar inseguranças e incertezas, que requerem compreensão da multidimensionalidade das situações, que sofrem interferências do meio pessoal, familiar e social, bem como da capacidade dos sistemas de saúde para o seu enfrentamento. Apesar dos desafios, a maioria dos participantes relatou disposição favorável para o autocuidado, seja para viabilizar retirada do cateter, ou para prevenir agravos em indicações vitalícias.
Abstract A long-term indwelling catheter may be indicated in clinical situations, such as chronic diseases of the genitourinary or neurological systems. In addition to the risks of infection, trauma, and bleeding, a catheter's permanence can affect psycho-emotional and socioeconomic dimensions. We aimed to understand how the need to use a long-term indwelling catheter affects this patient's self-perception, interrelationships, and self-care. We carried out a qualitative, descriptive study based on interviews with 17 patients, and applied thematic analysis and complex thinking. The different prognoses and expectations regarding the catheter influenced self-perception, adaptation, acceptance, or denial. The presence of a catheter, whether as a curative measure or for comfort, can affect self-image and sexuality, and generate insecurities and uncertainties, which require understanding the multidimensionality of situations that suffer interference from the personal, family, and social environment, as well as health systems' capacity to deal with it. Despite the challenges, the majority of participants reported a favorable disposition towards self-care, whether to enable catheter removal or to prevent injuries in lifelong indications.
RESUMO
Urofacial syndrome or Ochoa syndrome (UFS or UFOS) is a rare disease characterized by inverted facial expression and bladder dysfunction that was described for the first time in Colombia. It is an autosomal recessive pathology with mutations in the HPSE2 and LRIG2 genes. However, 16% of patients do not have any mutations associated with the syndrome. Despite the importance of neurobiology in its pathophysiology, there are no neurological, neuropsychological, or psychological studies in these patients. A 30-year-old male from Medellín, Colombia, with a significant perinatal history, was diagnosed with grade 4 hydronephrosis on his first ultrasound test. At 4 months of age, symptoms such as hypomimia, lagophthalmos, and recurrent urinary tract infections started to manifest. Imaging studies revealed urinary tract dilatation, vesicoureteral reflux, and a double collector system on his left side, which led to the diagnosis of UFS. Multiple procedures, including vesicostomy, ureterostomy, and enterocystoplasty, were performed. At 20 years of age, he achieved urinary sphincter control. Genetic analysis revealed a founder pathogenic variant, c.1516C > T (p.Arg506Ter), in the HPSE2 gene, which produces a truncated protein that lacks 86 amino acids. This variant is classified as pathogenic according to the ClinVar database for UFS. The mutation age is approximately 260-360 years, and the two alleles share a 7.2-7.4 Mb IBD segment. Moreover, we detected European local ancestry in the IBD segment, which is consistent with a Spanish introduction. Neurological examination, neuropsychological assessment, and psychological testing revealed no abnormalities, except for high stress levels. Clinical analysis of this patient revealed distorted facial expression and detrusor-sphincter dyssynergia, which are typical of patients with UFS. Genetic analysis revealed a pathogenic variant in the HPSE2 gene of European origin and a mutation age of 260-360 years. From a neurological, neuropsychological, and psychological (emotional and personality) perspective, the patient showed no signs or symptoms of clinical interest.
RESUMO
OBJECTIVE: To assess the long-term outcome of renal oligohydramnios and risk factors for fetal, neonatal, and postneonatal death. STUDY DESIGN: This retrospective cohort study included fetuses with prenatally detected renal oligohydramnios between 2002 and 2023. Patients who were lost to follow-up were excluded. Fetal, neonatal, and long-term outcomes were evaluated, and their risk factors were analyzed. RESULTS: Of 131 fetuses with renal oligohydramnios, 46 (35%) underwent a termination of pregnancy, 11 (8%) had an intrauterine fetal death, 26 (20%) had a neonatal death, nine (7%) had a postneonatal death, and 39 (30%) survived. Logistic regression analyses showed that an earlier gestational age at onset (OR 1.16, 95% CI 1.01-1.37) was significantly associated with intrauterine fetal death; anhydramnios (OR 12.7, 95% CI 1.52-106.7) was significantly associated with neonatal death as a prenatal factor. Although neonatal survival rates for bilateral renal agenesis, bilateral multicystic dysplastic kidney (MCDK), and unilateral MCDK with contralateral renal agenesis were lower than for other kidney diseases, 1 case of bilateral renal agenesis and two of bilateral MCDK survived with fetal intervention. Kaplan-Meier overall survival rates were 57%, 55%, and 51% for 1, 3, and 5 years, respectively. In the Cox proportional hazards model, birth weight <2000 g (hazard ratio 7.33, 95% CI 1.48-36.1) and gastrointestinal comorbidity (hazard ratio 4.37, 95% CI 1.03-18.5) were significant risk factors for postneonatal death. CONCLUSION: Long-term survival following renal oligohydramnios is a feasible goal and its appropriate risk assessment is important.
RESUMO
The Prune-Belly (Eagle-Barrett) syndrome (PBS) is a congenital and genetically heterogeneous disease, more prevalent in males, defined by the clinical triad (1) deficiency of abdominal muscles, (2) bilateral cryptorchidism, and (3) urinary tract abnormalities. The abdomen of an infant with PBS has a typical appearance, similar to the aspect of a prune, which gives it its name. Although the etiology of this disorder is still unknown, numerous theories, mutations, and genetic disturbances have been proposed to explain the origin of PBS. Prognosis can differ a lot from one patient to another, since this condition has a wide spectrum of clinical presentation. Despite being a rare condition, the importance of PBS should not be underestimated, in the light of the potential of the disorder to lead to chronic kidney disease and other severe complications. In that regard, this review gathers the most up-to-date knowledge about the etiopathogenesis, clinical features, diagnosis, management and prognosis of PBS.
RESUMO
Uropathogenic Escherichia coli (UPEC) is the main cause of urinary tract infections (UTIs) and carries virulence and resistance factors often found in mobilizable genetic elements, such as plasmids or pathogenicity islands (PAIs). UPEC is part of the extraintestinal pathogenic E. coli (ExPEC), but hybrid strains possessing both diarrheagenic E. coli (DEC) and ExPEC traits, termed "hypervirulent", present a significant health threat. This study assessed the prevalence of UPEC PAIs, ExPEC sequence types (ST), DEC genes, carbapenemase and extended-spectrum ß-lactamase (ESBL) phenotypes, resistance genotypes, and plasmids in 40 clinical isolates of UPEC. Results showed that 72.5% of isolates had PAIs, mainly PAI IV536 (53%). ESBL phenotypes were found in 65% of ß-lactam-resistant isolates, with 100% of carbapenem-resistant isolates producing carbapenemase. The predominant ESBL gene was blaCTX-M-2 (60%), and the most common resistance gene in fluoroquinolone and aminoglycoside-resistant isolates was aac(6')Ib (93%). Plasmids were present in 57% of isolates, and 70% belonged to the ST131 clonal group. Molecular markers for DEC pathotypes were detected in 20 isolates, with 60% classified as hybrid pathotypes. These findings indicate significant pathogenic potential and the presence of hybrid pathotypes in E. coli UTI clinical isolates in the Mexican population.
RESUMO
Overuse of antimicrobials has greatly contributed to the increase in the emergence of multidrug-resistant bacteria, a situation that hinders the control and treatment of infectious diseases. This is the case with urinary tract infections (UTIs), which represent a substantial percentage of worldwide public health problems, thus the need to look for alternatives for their control and treatment. Previous studies have shown the usefulness of autologous bacterial lysates as an alternative for the treatment and control of UTIs. However, a limitation is the high cost of producing individual immunogens. At the same time, an important aspect of vaccines is their immunogenic amplitude, which is the reason why they must be constituted of diverse antigenic components. In the case of UTIs, the etiology of the disease is associated with different bacteria, and even Escherichia coli, the main causal agent of the disease, is made up of several antigenic variants. In this work, we present results on the study of a bacterial lysate composed of 10 serotypes of Escherichia coli and by Klebsiella pneumoniae, Klebsiella aerogenes, Enterococcus faecalis, Proteus mirabilis, Citrobacter freundii, and Staphylococcus haemolyticus. The safety of the compound was tested on cells in culture and in an animal model, and its immunogenic capacity by analysing in vitro human and murine macrophages (cell line J774 A1). The results show that the polyvalent lysate did not cause damage to the cells in culture or alterations in the animal model used. The immunostimulatory activity assay showed that it activates the secretion of TNF-α and IL-6 in human macrophages and TNF-α in murine cells. The obtained results suggest that the polyvalent lysate evaluated can be an alternative for the treatment and control of chronic urinary tract infections, which will reduce the use of antimicrobials.

OBJECTIVE: To identify factors associated with overtreatment of presumed urinary tract infection (UTI) among children with spina bifida using such criteria. STUDY DESIGN: A retrospective review of children with spina bifida (age <21 years) evaluated in the Emergency Department (ED) at a single institution was performed. Patients with a urinalysis (UA) performed who were reliant on assisted bladder emptying were included. The primary outcome was overtreatment, defined as receiving antibiotics for presumed UTI but ultimately not meeting spina bifida UTI criteria (≥2 urologic symptoms plus pyuria and urine culture growing >100k CFU/mL). The primary exposure was whether the components of the criteria available at the time of the ED visit (≥2 urologic symptoms plus pyuria) were met when antibiotics were initiated. RESULTS: Among 236 ED encounters, overtreatment occurred in 80% of cases in which antibiotics were initiated (47% of the entire cohort). Pyuria with <2 urologic symptoms was the most important factor associated with overtreatment (OR 9.6). Non-Hispanic White race was associated with decreased odds of overtreatment (OR 0.3). CONCLUSIONS: Overtreatment of presumed UTI among patients with spina bifida was common. Pyuria, which is not specific to UTI in this population, was the main driver of overtreatment. Symptoms are a cornerstone of UTI diagnosis among children with spina bifida, should be collected in a standardized manner, and considered in a decision to treat.

Urinary tract infections (UTIs) are pervasive in human and veterinary medicine, notably affecting companion animals. These infections frequently lead to the prescription of antibiotics, contributing to the rise of antimicrobial-resistant bacteria. This escalating concern is underscored by the emergence of a previously undocumented case: a high-risk clone, broad-spectrum cephalosporin-resistant K. pneumoniae ST147 strain, denoted USP-275675, isolated from a cat with UTI. Characterized by a multidrug-resistant (MDR) profile, whole genome sequencing exposed several antimicrobial-resistance genes, notably blaCTX-M-15, blaTEM-1B, blaSHV-11, and blaOXA-1. ST147, recognized as a high-risk clone, has historically disseminated globally and is frequently associated with carbapenemases and extended-spectrum ß-lactamases. Notably, the core-genome phylogeny of K. pneumoniae ST147 strains isolated from urine samples revealed a unique aspect of the USP-276575 strain. Unlike its counterparts, it did not cluster with other isolates. However, a broader examination incorporating strains from both human and animal sources unveiled a connection between USP-276575 and a Portuguese strain from chicken meat. Both were part of a larger cluster of ST147 strains spanning various geographic locations and sample types, sharing commonalities such as IncFIB or IncR plasmids. This elucidates the MDR signature inherent in widespread K. pneumoniae ST147 strains carrying these plasmids, highlighting their pivotal role in disseminating antimicrobial resistance (AMR). Finally, discovering the high-risk clone K. pneumoniae ST147 in a domestic feline with a UTI in Brazil highlights the urgent need for thorough AMR surveillance through a One Health approach.

INTRODUCTION: Percutaneous nephrostomy tubes (PNT), which are used in some cancer hospitals, are associated with an increase in urinary tract infections (UTI). OBJECTIVE: To determine the impact of a standardized care program on the incidence of UTIs requiring hospitalization (UTI-RH). MATERIAL AND METHODS: Retrospective study that included patients with a first PNT inserted. The incidence, relative risk (RR), costs and outcomes of patients with UTI-RH were compared during the period before (P0) vs. after the intervention (P1). RESULTS: 113 PNTs were inserted during P0, and 74 at P1. During P0, 61 patients (53.9%) experienced 64 UTI-RH events in 22,557 PNT days. At P1, four patients (5.4%) had a UTI-RH in 6,548 PNT days (IRR: 0.21, 95% CI: 0.05-0.57). The RR was 0.09 (95% CI: 0.03-0.25). Monthly cost per day/bed was USD 3,823 at P0 and USD 1,076 at P1, and for antibiotics, it was USD 790 at P0 and USD 123.5 at P1. CONCLUSIONS: This study highlights the importance of a standardized care program for permanent percutaneous devices, since this reduces antibiotic use, hospitalization, and the cost of care.
ANTECEDENTES: Los catéteres de nefrostomía percutánea (CNP) que se utilizan en algunos hospitales oncológicos condicionan un incremento en las infecciones del tracto urinario (ITU). OBJETIVO: Determinar el impacto de un programa estandarizado de atención en la incidencia de ITU que requiere hospitalización (ITU-RH). MATERIAL Y MÉTODOS: Estudio retrospectivo que incluyó pacientes con un primer CNP. Se comparó la incidencia, riesgo relativo (RR), costos y evolución de los pacientes con ITU-RH durante el período previo a la intervención (P0) versus posterior a ella (P1). RESULTADOS: Se instalaron 113 CNP durante P0 y 74 durante P1. Durante P0, 61 pacientes (53.9 %) presentaron 64 episodios de ITU-RH, en 22 557 días de uso de CNP. Durante P1, cuatro pacientes (5.4%) cursaron con ITU-RH en el transcurso de 6548 días de uso del CNP (razón de tasa de incidencia de 0.21, IC 95 % = 0.05-0.57). El RR fue de 0.09 (IC 95 % = 0.03-0.25). El costo mensual por día-cama fue de 3823 USD en P0 y de 1076 USD en P1; el de los antibióticos, de 790 USD en P0 y 123.5 USD en P1. CONCLUSIONES: Este estudio resalta la importancia de un programa estandarizado del cuidado de los dispositivos permanentes, el cual disminuye el uso de antibióticos, la hospitalización y el costo de la atención.
