Management of Urinary Tract Infections and Vesicoureteric Reflux: Key Updates From Revised Indian Society of Pediatric Nephrology Guidelines 2023.

Non-specific symptoms and difficulty in collecting urine specimens make the diagnosis of urinary tract infection (UTI) challenging in children. However, timely diagnosis and initiation of therapy are essential to prevent complications. Children with recurrent UTIs require detailed evaluation and follow-up for optimal management. We report key updates from the revised evidence-based practice guidelines of the Indian Society of Pediatric Nephrology for UTIs and primary vesicoureteric reflux.

Phage vB_Ec_ZCEC14 to treat antibiotic-resistant Escherichia coli isolated from urinary tract infections.

Escherichia coli is a commensal bacterial species in the human gastrointestinal tract; however, it could be pathogenic and cause severe infections in intra and extra-intestinal sites. Uropathogenic E. coli accounts for 80-90% of urinary tract infections that can result in urosepsis and septic shock. Consequently, multidrug-resistant uropathogenic E. coli poses a considerable risk to the healthcare system worldwide. Phage therapy is demonstrated as an optimistic solution to over-the-counter antibiotics that contribute to the global issue of multidrug-resistant bacteria. This study aims to isolate a novel phage that could be implemented to cure urinary tract infections mediated by multidrug-resistant E. coli. Twenty-seven E. coli isolates were collected from patients with urinary tract infections to assess the antibacterial efficacy of phage vB_Ec_ZCEC14. Phage kinetics were encountered against the E. coli strain (EC/4), in addition to evaluating phage stability under various temperatures, pH values, and UV exposure periods. Full genome sequencing and morphological analysis were conducted for further phage characterization, which revealed that phage vB_Ec_ZCEC14 belongs to the family Straboviridae. Phage vB_Ec_ZCEC14 showed thermal tolerance at 80 ℃, pH stability between pH 3 and pH 12, and endurance to UV exposure for 45 min. The phage-host interaction results revealed that phage vB_Ec_ZCEC14 has strong and steady antibacterial action at lower concentrations (MOI 0.1). The study findings strongly indicate that phage vB_Ec_ZCEC14 holds significant promise as a potential therapeutic alternative for treatment of antibiotic-resistant uropathogenic E. coli.

Update and Summary of the European Association of Urology/European Society of Paediatric Urology Paediatric Guidelines on Vesicoureteral Reflux in Children.

BACKGROUND AND OBJECTIVE: The prescriptive literature on vesicoureteral reflux (VUR) is still limited and thus the level of evidence is generally low. The aim of these guidelines is to provide a practical approach to the treatment of VUR that is based on risk analysis and selective indications for both diagnostic tests and interventions. We provide a 2023 update on the chapter on VUR in children from the European Association of Urology (EAU) and European Society for Paediatric Urology (ESPU) guidelines. METHODS: A structured literature review was performed for all relevant publications published from the last update up to March 2022. KEY FINDINGS AND LIMITATIONS: The most important updates are as follows. Bladder and bowel dysfunction (BBD) is common in toilet-trained children presenting with urinary tract infection (UTI) with or without primary VUR and increases the risk of febrile UTI and focal uptake defects on a radionuclide scan. Continuous antibiotic prophylaxis (CAP) may not be required in every VUR patient. Although the literature does not provide any reliable information on CAP duration in VUR patients, a practical approach would be to consider CAP until there is no further BBD. Recommendations for children with febrile UTI and high-grade VUR include initial medical treatment, with surgical care reserved for CAP noncompliance, breakthrough febrile UTIs despite CAP, and symptomatic VUR that persists during long-term follow-up. Comparison of laparoscopic extravesical versus transvesicoscopic ureteral reimplantation demonstrated that both are good option in terms of resolution and complication rates. Extravesical surgery is the most common approach used for robotic reimplantation, with a wide range of variations and success rates. CONCLUSIONS AND CLINICAL IMPLICATIONS: This summary of the updated 2023 EAU/ESPU guidelines provides practical considerations for the management and diagnostic evaluation of VUR in children. ADVANCING PRACTICE: For children with VUR, it is important to treat BBD if present. A practical approach regarding the duration of CAP is to consider administration until BBD resolution. PATIENT SUMMARY: We provide a summary and update of guidelines on the diagnosis and management of urinary reflux (where urine flows back up through the urinary tract) in children. Treatment of bladder and bowel dysfunction is critical, as this is common in toilet-trained children presenting with urinary tract infection.

Patient Perception and Impact of Home Test Kits on Health Care Utilization for Urinary Tract Infection.

Urinary tract infection (UTI) is a common reason for emergency department (ED) utilization that could potentially be treated by a primary care provider (PCP). This study assessed patient perceived value of a home UTI test kit plus educational materials and its impact on ED utilization for a UTI symptom episode. Women aged 18-75 years with Medicaid insurance and a history of 1-3 uncomplicated UTIs in the past year were prospectively identified and randomized to the intervention, intervention plus (intervention plus a patient portal message before its delivery), or standard of care group. A telephone survey was conducted 3-5 months after the mailing. Site of care for each UTI symptom episode was measured 12 months before and 6 months after the intervention. Test kit packages were mailed to 266 intervention individuals, and 150 responded to the telephone survey. Utilization outcomes were compared between a combined intervention group and a control group. Approximately one-third of the intervention patients experienced UTI symptoms within 5 months, and 73% used the test kit. Of those who experienced UTI symptoms, 58% contacted their PCP to seek care and 96% reported that the test kit was helpful. ED utilization was not significantly different in the intervention groups before and after the intervention, nor between the intervention and control groups postintervention. A home UTI test kit plus educational materials mailed to patients with a history of uncomplicated UTI was deemed helpful but did not have a measurable impact on ED utilization.

Urinary catheterization of patients with acute heart failure in a hospital emergency department: a factor associated with prognosis. / El sondaje vesical de los pacientes con insuficiencia cardiaca aguda en un servicio de urgencias hospitalario se asocia al pronóstico.

OBJECTIVES: To analyze whether urinary catheterization in a hospital emergency department (ED) affects short-term prognosis in patients with acute heart failure (AHF). MATERIAL AND METHODS: We prospectively recorded baseline and other clinical data in a consecutive cohort of ED patients treated for AHF. Crude and adjusted associations were calculated between catheterization and a primary composite outcome (30-day readmission for AHF and/or death) and secondary outcomes (in-hospital mortality, urinary tract infection [UTI], and duration of hospital stay.). RESULTS: Nine hundred ninety-one patients were admitted for AHF. The mean (SD) age was 66 (10.5) years; 71% were women. Catheterization was required for 29.2% in the ED. The primary composite outcome was observed in 7.7% of the patients who were not catheterized and 12.8% of the catheterized patients (P = .02). In-hospital mortality occurred in 5.9% and 9.7% of non-catheterized and catheterized patients, respectively (P = .04), and UTIs occurred in 19.1% and 26.6% (P = .01). Twelve of the non-catheterized patients (1.7%) were readmitted for AHF (vs 11 (3.8%) of the catheterized patients (P = .06), and there were no differences between the groups in hospital stay (11 vs 10.9 days, P = .78). In the adjusted analysis of associations between catheterization and the primary outcome the odds and hazard ratios (OR and HR, respectively) were OR, 1.7 (95% CI, 1.1-2.7) (P = .02) and HR, 1.6 (95% CI, 1.1-2.5) (P = .03). For secondary outcomes, significant associations emerged between catheterization and UTIs (OR, 1.8 [95% CI, 1.1-2.2]; P = .008) and readmission for AHF (OR, 2.9 [95% CI, 1.2-7.3]; P = .02). CONCLUSION: Routine insertion of a urinary catheter in patients with AHF in the ED is associated with worse 30-day clinical outcomes.

OBJETIVO: Analizar si el sondaje vesical (SV) rutinario en un servicio de urgencias hospitalario (SUH) de pacientes diagnosticados de insuficiencia cardiaca aguda (ICA) está asociado con la evolución a corto plazo. METODO: Se recogieron prospectivamente datos basales y clínicos de una cohorte de pacientes consecutivos que ingresaron por ICA. Se analizó la asociación cruda y ajustada del SV con el evento combinado de muerte o reingreso por insuficiencia cardiaca a 30 días (objetivo primario), así como mortalidad intrahospitalaria, infección del tracto urinario (ITU) y estancia hospitalaria (objetivos secundarios). RESULTADOS: Se incluyeron 991 pacientes hospitalizados por ICA, la edad media fue de 66 años (DE 10,5) y el 71% fueron mujeres. Un 29,2% de los pacientes requirieron SV en el SUH. El evento combinado fue del 7,7% para el grupo no SV y 12,8% para grupo SV (p = 0,02); mortalidad intrahospitalaria fue del 5,9% en el grupo no SV y 9,7% en el grupo SV (p = 0,04); se diagnosticó ITU en el 19,1% de pacientes en el grupo no SV y en el 26,6% en el grupo SV (p = 0,01). A 30 días, 12 pacientes (1,7%) reingresaron por insuficiencia cardiaca en el grupo no SV versus 11 (3,8%) pacientes en el grupo SV (p = 0,06). No hubo diferencias en la estancia hospitalaria (11 versus 10,9 días); p = 0,78). En el análisis ajustado, el SV se asoció con el objetivo primario; [OR = 1,7 (IC 95%: 1,1-2,7; p = 0,02); HR = 1,6 (IC 95%: 1,1-2,5; p = 0,03)]; con la ITU (OR = 1,8; IC 95%: 1,1­2,2; p = 0,008) y con el reingreso por insuficiencia cardiaca (OR = 2,9; IC 95%: 1,2-7,3; p = 0,02). CONCLUSIONES: La inserción rutinaria del SV en el SUH en pacientes con ICA se asoció a peores resultados clínicos a los 30 días.

National Trends in Voiding Cystourethrograms During Hospitalization for Young Infants With Urinary Tract Infections.

OBJECTIVES: The American Academy of Pediatrics published a guideline in 2011 recommending against the routine use of voiding cystourethrogram (VCUG) in infants aged 2 to 24 months with first febrile urinary tract infection (UTI); however, the rates of VCUG for infants aged <2 months are unknown. The objective of this study was to determine the trend in VCUG performance during index hospitalization among infants aged 0 to 2 months with UTI. METHODS: This retrospective cohort study included infants aged birth to 2 months hospitalized with a UTI from 2008 to 2019 across 38 institutions in the Pediatric Health Information System. Outcome measures included recurrent UTI within 1 year, vesicoureteral reflux diagnosis within 1 year and antiurinary reflux procedure performed within 2 years. Trends over time were compared between preguideline (2008-2011) and postguideline periods (2012-2019) using piecewise mixed-effects logistic regression. RESULTS: The odds of VCUG decreased by 21% per year in the preguideline period (adjusted odds ratio, 0.79; 95% confidence interval, 0.77-0.81; P < .001) versus 20% (adjusted odds ratio, 0.80; 95% confidence interval, 0.77-0.83; P < .001) in the postguideline period. The preguideline and postguideline difference was not statistically significant (P = .60). There was no difference in the postguideline odds of UTI within 1 year (P = .07), whereas the odds of vesicoureteral reflux diagnosis (P < .001) and antiurinary reflux procedure performance (P < .001) decreased. CONCLUSIONS: VCUG performance during hospitalization has declined over the past decade among young infants hospitalized with UTI. Further work is needed to determine the optimal approach to imaging in these young infants.

Systematic review and meta-analysis to study the outcomes of proactive versus delayed management in children with a congenital neurogenic bladder.

PURPOSE: To review the urological outcomes of proactive versus delayed management of children with a neurogenic bladder (NB). METHODS: We performed a literature search on EMBASE, MEDLINE, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials between January 1, 2000 to August 21, 2023 for studies investigating the management of spina bifida-associated NB in pediatric patients (0-18 years of age). Proactive management was defined as use of clean intermittent catheterization, and/or anticholinergics at presentation, or based on initial high-risk urodynamic findings by 1 year of age. Delayed management was defined as beginning management after 1 year of age or no intervention. Outcomes included incidence or diagnosis of secondary vesicoureteral reflux (VUR), urinary tract infection (UTI), and renal deterioration, which included renal scarring, loss of differential renal function on a nuclear scan, or a decrease in renal function defined by glomerular filtration rate or serum creatinine estimation. Forest plots were synthesized using the Inverse Variance method with random-effect model. The Risk of Bias was assessed using the ROBINS-I tool. RESULTS: We included 8 observational studies on 652 pediatric patients with spina bifida-associated NB (mean follow-up - 7 years). Proactive management following initial assessment was associated with significantly lower risks of secondary VUR (OR 0.37 [0.19, 0.74], p = 0.004), non-febrile UTI (OR 0.35 [0.19, 0.62], p = 0.0004), and renal deterioration (OR 0.31 [0.20, 0.47], p < 0.00001). DISCUSSION: Delayed management of NB potentially has 3 times higher risks of secondary VUR, non-febrile UTI, and renal deterioration. However, the evidence is limited by the high risk of bias due to lack of randomization and standardized reporting in observational studies. CONCLUSION: While further well-defined prospective studies with long-term follow-up should be conducted to confirm this finding, this study supports the EAU/ESPU recommendations for early intervention in children with NB.

Correlation of the Degree of Hydronephrosis and Computed Tomography Value of Calculi with Efficacy of Ureteroscopic Lithotripsy in Patients with Upper Urinary Tract Infectious Calculi

Objective: The correlation of the degree of hydronephrosis and computed tomography (CT) value of calculi with the efficacy of ureteroscopic lithotripsy (URSL) in patients with upper urinary tract infectious calculi was explored. Methods: The clinical data of 152 patients with upper urinary tract infectious calculi and on URSL in Shanghai Baoshan District Wusong Central Hospital from November 2019 to November 2021 were collected for retrospective analysis. All patients received CT examination before surgery. According to the therapeutic effect of URSL, all patients were divided into the non-calculi group (NCG, n = 101) and residual calculi group (RCG, n = 51), which were compared in terms of the degree of hydronephrosis and CT value of calculi. Then, the correlation of the degree of hydronephrosis and CT value of calculi with the efficacy of URSL in patients was analysed. Results: No significant difference in clinical data was found between the groups (p > 0.05). Patients in the NCG group had lower degree of hydronephrosis than those in the RCG group (p < 0.05), and the NCG had lower CT value of calculi (p < 0.001). Spearman rank correlation analysis showed that the degree of hydronephrosis in patients with upper urinary tract infectious calculi was negatively correlated with the efficacy of URSL (r = −0.676, p < 0.001), and the CT value of calculi in such patients was negatively correlated with the efficacy of URSL (r = −0.795, p < 0.001). Conclusions: The degree of hydronephrosis and CT value of calculi were negatively correlated with the efficacy of URSL. Both can be used to predict clinical efficacy and have clinical guiding value for the formulation of treatment plans in patients with urinary tract infectious calculi (AU)

Analysis of uroseptic shock after ureteroscopy for ureteral calculi during pregnancy: a case report.

BACKGROUND: Uroseptic shock secondary to ureteral calculi during pregnancy is rare. It is characterized by rapid onset, rapid progression, aggressive disease, limited treatment, poor prognosis, and a mortality rate higher than 20% with improper or delayed management. A clear diagnosis is made based on typical clinical symptoms and abdominal ultrasound, often requiring combined multidisciplinary treatment and the simultaneous release of the obstruction. The high mortality rate is mainly related to inappropriate early treatment of stones and infections or failure to intervene in a timely manner. CASE PRESENTATION: A 21-year-old first-time pregnant patient with uroseptic shock was admitted to our intensive care unit. The patient was successfully treated at our hospital with multidisciplinary cooperation, high-dose vasoactive drugs, IABP, CRRT, VA-ECMO, and termination of pregnancy. CONCLUSIONS: Timely relief of obstructions, termination of pregnancy, and the provision of IABP, CRRT, and VA-ECMO when necessary in critically ill patients with uroseptic shock during pregnancy can improve the success rate of resuscitation.

Reduction in urinary tract infections in patients treated with fecal microbiota transplantation for recurrent Clostridioides difficile infection.

We performed an updated study to investigate the rates of urinary tract infections (UTIs) in patients with recurrent Clostridioides difficile infection (CDI) who received fecal microbiota transplantation (FMT) for CDI. We found a significant reduction in number of UTIs after FMT compared to patients who received antibiotics for CDI treatment. After FMT, we also observed a trend towards reduction of antibiotic resistance in organisms causing UTI.

Dysfunctional Voiding: Exploring Disease Transition From Childhood to Adulthood.

OBJECTIVE: To improve our transitional care, we explored how childhood dysfunctional voiding (DV) develops into adulthood. DV is a common condition in both children and adults. However, the long-term course of childhood DV into adulthood is unknown and treatment over the ages differs. METHODS: A cross-sectional follow-up was performed in a cohort of 123 females treated from 2000 to 2003 for childhood DV with urinary tract infections (UTIs) and/or daytime urinary incontinence (DUI). The main outcome was a staccato or intermittent urinary flow pattern, possibly indicating persistent or recurred DV according to the International Continence Society criteria. Flow patterns of healthy women were used to compare results. RESULTS: Twenty-five patients participated in this study, with a mean duration of 20.8 years after urotherapy. In 10/25 (40%) cases, a staccato or interrupted urinary flow pattern was found on the current measurement, compared to 5/47 (10.6%) in the control group. Around 50% (5/10) of the patients with a dysfunctional flow pattern reported UTIs and 50% (5/10) experienced DUI. In the group with a normal flow pattern, 2/15 (13%) reported UTIs and 9/15 (60%) DUI. The impact of DUI on quality of life was moderate to high in both groups. CONCLUSION: Our results show that 40% of females who had extensive urotherapy for DV in childhood, still have DV according to International Continence Society criteria as an adult, 56% still experience DUI, and 28% UTIs. These data should be taken into account in the counseling of patients and for guiding the process of transition into adulthood.

Urologic view in the management of genitourinary syndrome of menopause.

Genitourinary syndrome of menopause (GSM) has a variety of effects on the urinary system and is an important consideration in the care provided to perimenopausal and postmenopausal patients when addressing urinary pathology. Here we discuss the common pathologies of the urinary system related to GSM including lower urinary tract symptoms and recurrent urinary tract infections. Female sexual dysfunction is not to be excluded as a critical part of a urologist's management of GSM but will be discussed elsewhere in this issue.

Consensus for the treatment of upper urinary tract infections during pregnancy / Consenso para el tratamiento de la infección de vías urinarias altas durante la gestación

Objectives: To generate evidence-based recommendations through formal consensus regarding the treatment of upper urinary tract infections during gestation. Materials and methods: Experts in microbiology, public health, internal medicine, infectious diseases, obstetrics, maternal fetal medicine and obstetric and gynecological infections participated in the consensus development group. The group also included professionals with training in clinical epidemiology, systematic data search, and representatives from the Health Secretariat and the Bogota Obstetrics and Gynecology Association. The participants disclosed their conflicts of interest. Starting with a clinical question, outcomes were graded and a systematic search was conducted in the Medline via PubMed, Embase, Lilacs, and Bireme databases. The search was expanded to include institutional repositories and antimicrobial resistance surveillance systems, with no language or date restrictions. The search was updated on October 1, 2022. The GRADE (Grading of Recommendations Assessment, Development and Evaluation) methodology was used to assess the quality of the evidence and determine the strength of the recommendations. Finally, the RAND/UCLA (Research and Development/University of California Los Angeles) methodology was applied for the formal consensus. This document was reviewed by academic peers before publication. Results: The following are the consensus recommendations. Recommendation 1. The initial management of pregnant women with upper urinary tract infections (UTIs) should be approached in a hospital setting. Recommendation 2. The use of second generation cephalosporins is the suggested first option for empirical antimicrobial management in pregnant women with upper UTI in order to improve the rates of clinical and microbiological cure. Recommendation 3. Because of the risk-benefit balance, the use of aminoglycosides is suggested as a second option for empirical antimicrobial treatment in pregnant women presenting with upper UTIs in the second and third trimester. Recommendation 4. The use of third-generation cephalosporins is suggested as the third option for empirical antimicrobial treatment in pregnant women with upper UTIs given that the risk of inducing microbial resistance is high with this group of antibiotics. Recommendation 5. The use of carbapenems is suggested as a first option in pregnant women with upper UTIs and a history of infections caused by microorganisms with resistance to third or fourth-generation cephalosporins. Recommendation 6. The use of aminoglycosides or fourth-generation cephalosporins is suggested as a second option in pregnant women with upper UTIs and a history of infection caused by microorganisms with resistance to third-generation cephalosporins, taking risk-benefit into account. Recommendation 7. The use of piperacillin/tazobactam is suggested as a third option in pregnant women with upper UTIs and a history of infection caused by microorganisms with resistance to third or fourthgeneration cephalosporins. Recommendation 8. Getting a urine culture is recommended in pregnant women with upper UTIs before initiating empirical antimicrobial treatment. Recommendation 9. In pregnant women with upper UTIs, it is suggested to modify therapy in accordance with the results of the sensitivity test when the culture report shows resistance to the antimicrobial agent initiated empirically. Recommendation 10. In pregnant women hospitalized due to upper UTIs, it is suggested to switch to oral antimicrobial therapy after at least 48 hours of modulation of the systemic inflammatory response and the clinical signs of infection, and when tolerance to oral intake is adequate. Recommendation 11. In pregnant women with upper UTIs with no complications secondary to the primary infection, it is recommended to administer antibiotic therapy for a period of 7 to 10 days. Conclusions: It is expected that with this Colombian upper UTI consensus variability in clinical practice will be reduced. It is recommended that groups doing research in maternal fetal medicine assess the implementation and effectiveness of these recommendations.

También hicieron parte profesionales con entrenamiento en epidemiología clínica, búsqueda sistemática de la información, representantes de la Secretaría de Salud y la Asociación Bogotana de Obstetricia y Ginecología. Los participantes presentaron sus conflictos de interés. A partir de una pregunta clínica se realizó la graduación de los desenlaces y una búsqueda sistemática que abarcó las bases de datos Medline vía PubMed, Embase, Lilacs, Bireme. La pesquisa se amplió a repositorios institucionales y reportes de vigilancia de resistencia antimicrobiana, sin restricción de idioma o fecha, la búsqueda se actualizó el 1 de octubre de 2022. Se utilizó la metodología GRADE (Grading of Recommendations Assessment, Development and Evaluation) para valorar la calidad de la evidencia y establecer la fuerza de las recomendaciones.Finalmente, se utilizó la metodología RAND/ UCLA (Research and Development/University of California Los Angeles) para el consenso formal. Este documento fue revisado por pares académicos previo a su publicación. Resultados: el consenso formuló las siguientes recomendaciones. Recomendación 1. Se sugiere que el manejo inicial de la gestante con infección de vías urinarias (IVU) altas se realice de forma intrahospitalaria. Recomendación 2. Como primera opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas se realice con el uso de cefalosporinas de segunda generación con el fin de mejorar la tasa de cura clínica y microbiológica. Recomendación 3. Como segunda opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas en el segundo y tercer trimestre se realice con aminoglucósidos dado su balance riesgo-beneficio. Recomendación 4. Como tercera opción, se sugiere que el tratamiento antimicrobiano empírico de la gestante con IVU altas se realice con el uso de cefalosporinas de tercera generación, debido a que el riesgo de inducción de resistencia microbiana es alto con este grupo de antibióticos. Recomendación 5. Como primera opción, en mujeres gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera o cuarta generación se sugiere el uso de carbapenémicos. Recomendación 6. Como segunda opción, en gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera generación se sugiere el uso de aminoglucósidos o cefalosporinas de cuarta generación teniendo en cuenta el riesgo-beneficio. Recomendación 7. Como tercera opción, en gestantes con IVU altas y antecedente de infección por microorganismos con resistencia a cefalosporinas de tercera o cuarta generación se sugiere el uso de piperacilina/tazobactam. Recomendación 8. En gestantes con IVU altas se recomienda realizar urocultivo previo al inicio de tratamiento antimicrobiano empírico. Recomendación 9. En gestantes con IVU altas, cuando el urocultivo reporte resistencia al antimicrobiano iniciado de forma empírica, se sugiere modificar la terapia guiada por los resultados del antibiograma. Recomendación 10. En la gestante hospitalizada por IVU altas se sugiere realizar el cambio de terapia antimicrobiana a vía oral cuando la paciente tenga, al menos, 48 horas de modulación de respuesta inflamatoria sistémica y de los signos clínicos de infección, así como adecuada tolerancia a vía oral. Recomendación 11. En gestantes con IVU altas, sin complicaciones secundarias a la infección primaria, se recomienda que la terapia antibiótica se administre de 7 a 10 días. Conclusiones: se espera que este consenso colombiano de IVU altas reduzca la variabilidad en la práctica clínica. Se recomienda a los grupos de investigación en medicina materno fetal e infectología evaluar la implementación y efectividad de las recomendaciones emitidas.

Efficiency of the Japanese Hospitalist System for Patients with Urinary Tract Infection: A Propensity-matched Analysis.

Objective The hospitalist system in the United States has been considered successful in terms of the quality of care and cost effectiveness. In Japan, however, its efficacy has not yet been extensively examined. This study examined the impact of the hospitalist system on the quality of care and healthcare economics in a Japanese population using treatment of urinary tract infection as an example. Methods We analyzed 271 patients whose most resource-consuming diagnosis at admission was urinary tract infection between April 2017 and March 2019. Propensity-matched analyses were performed to compare health care economics and the quality of care between the hospitalist system and the conventional system. Results In matched pairs, care by the hospitalist system was associated with a significantly shorter length of stay than that by the conventional system. The quality of care (oral antibiotics switch rate, rate of appropriate antibiotics change based on urine or blood culture results, detection rate of urinary tract infection etiology and the number of laboratory tests) was also considered to be favorably impacted by the hospitalist system. Although not statistically significant, hospital costs tended to be lower with the hospitalist system than with the conventional system. The mortality rate and 30-day readmission were also not significantly different between the groups. Conclusion The hospitalist system had a favorable impact on the quality of care and length of stay without increasing readmission in patients with urinary tract infection. This study is further evidence of the strong potential for the positive impact of an implemented hospitalist system in Japan.

The Tumor Necrosis Factor-α Level in Platelet-Rich Plasma Might Be Associated with Treatment Outcome in Patients with Interstitial Cystitis/Bladder Pain Syndrome or Recurrent Urinary Tract Infection.

Using platelet-rich plasma (PRP) injections to treat urological diseases has attracted great attention. This study investigated the impact of cytokine concentrations in PRP on the treatment outcome of patients with recurrent urinary tract infection (rUTI) and interstitial cystitis/bladder pain syndrome (IC/BPS). Forty patients with IC/BPS and twenty-one patients with rUTI were enrolled for four-monthly repeated PRP injections. PRP was collected at the first injection and analyzed with multiplex immunoassays for 12 target cytokines. In patients with IC/BPS, a Global Response Assessment (GRA) score ≥ 2 was defined as a successful outcome. In rUTI patients, ≤2 episodes of UTI recurrence during one year of follow-up was considered a successful outcome. Nineteen (47.5%) patients with IC/BPS and eleven (52.4%) patients with rUTI had successful outcomes. The IC/BPS patients with successful outcomes had significantly lower levels of tumor necrosis factor-α (TNF-α) in their PRP than those with unsuccessful outcomes (p = 0.041). The rUTI patients with successful outcomes also had a lower level of TNF-α (p = 0.025) and a higher level of epidermal growth factor (p = 0.035) and transforming growth factor-ß2 (p = 0.024) in PRP than those with unsuccessful outcomes. A lower level of TNF-α in PRP might be a potentially predictive factor of treatment outcome.

A case report: Intermittent catheterization combined with rehabilitation in the treatment of carbapenem-resistant Klebsiella pneumoniae catheter-associated urinary tract infection.

Catheter-related urinary tract infections, especially those caused by multidrug-resistant (MDR) bacteria, are extremely difficult to treat due to limited therapeutic choices. Therefore, removing catheters as soon as possible is pivotal to successful treatment. Herein, we report a case of catheter-related urinary tract infection caused by carbapenem-resistant Klebsiella pneumoniae (CRKP). Intermittent catheterization was used to reduce biofilm occurrence and exercise bladder function on the basis of an active and adequate anti-infection strategy. Simultaneously, combined with acupuncture treatment and strengthening the patient's pelvic floor muscle training to improve urinary retention, the catheter was eventually removed to obtain autonomous urination in this patient, and this led to the successful treatment for a CRKP catheter-related urinary tract infection.

Healthcare providers' compliance with guidelines for catheter-associated urinary tract infections in a rural teaching and referral hospital / Cumplimiento de las pautas para las infecciones del tracto urinario asociadas con el catéter por parte de los proveedores de atención médica en un hospital rural docente y de referencia

Introduction: Healthcare professionals (HCPs) play a key role in the prevention of catheter-associated urinary tract infections (CAUTI). This study aims to determine the compliance of healthcare personnel with urethral catheterisation standards and the factors affecting it. Materials and Methods: This study is a prospective survey and was conducted between February and March 2021 after ethical approval and patient consent. An internet-based, structured 39-item questionnaire was sent via email to all HCPs at Zonguldak Bulent Ecevit University Hospital, Zonguldak, Turkey. A to evaluate their knowledge and attitudes towards the prevention of CAUTI. The questionnaire was completed by 156 health professionals. For categorical parameters Fisher’s exact test, though for scale parameters student t-test, Mann–Whitney U and Kruskal–Wallis tests were used. All statistical analysis was done using SPSS 17.0. Results: The average years of experience of the HCPs who participated in the survey was 12.5 years. The level of knowledge of the doctors and the nurses about the indication of catheter insertion was similar, whereas the level of knowledge about CAUTI prevention was higher among the doctors. However, none of the participants could fully describe how to prevent CAUTI. Conclusions: The level of knowledge of CAUTI preventive measures among the participants was insufficient. To effectively preventing CAUTI, there is a need to change HCPs’ perspective on this issue, which can be achieved through training, and advantage current technologies. (AU)

Introducción: Los profesionales de la salud (PS) juegan un papel clave en la prevención de infecciones del tracto urinario asociadas al catéter (ITUAC). Este estudio tiene como objetivo determinar el cumplimiento de las normas de sondaje uretral por parte del personal sanitario y los factores que lo afectan. Materiales y métodos: Este estudio es una encuesta prospectiva y se realizó entre febrero y marzo de 2021 después de la aprobación ética y el consentimiento del paciente. Se envió un cuestionario estructurado de 39 ítems basado en Internet por correo electrónico a todos los HCP en el Hospital Universitario Zonguldak Bulent Ecevit, Zonguldak, Turquía. A para evaluar sus conocimientos y actitudes hacia la prevención de la ITUAC. El cuestionario fue completado por 156 profesionales de la salud. Para los parámetros categóricos se utilizó la prueba exacta de Fisher, aunque para los parámetros de escala se utilizaron la prueba t de Student, la U de Mann-Whitney y la de Kruskal-Wallis. Todos los análisis estadísticos se realizaron con SPSS 17.0. Resultados: El promedio de años de experiencia de los profesionales de la salud que participaron en la encuesta fue de 12,5 años. El nivel de conocimiento de los médicos y las enfermeras sobre la indicación de la inserción del catéter fue similar, mientras que el nivel de conocimiento sobre la prevención de las ITUAC fue mayor entre los médicos. Sin embargo, ninguno de los participantes pudo describir completamente cómo prevenir ITUAC. Conclusiones: El nivel de conocimiento de las medidas preventivas de ITUAC entre los participantes fue insuficiente. Para prevenir CAUTI de manera efectiva, es necesario cambiar la perspectiva de los profesionales de la salud sobre este tema, lo que se puede lograr a través de la capacitación y aprovechar las tecnologías actuales.

[Clinical practice guideline for the diagnosis and management of urinary tract infections: 2022 update]. / Guía para el diagnóstico, estudio y tratamiento de la infección urinaria: actualización 2022.

In 2015, the "New recommendations regarding the current controversies in urinary infection" were published in the Archivos Argentinos de Pediatría. Given the fact that in these past years, new evidence has emerged regarding the diagnosis and treatment of urinary infection, the Pediatric Nephrology Committee of Sociedad Argentina de Pediatría has decided to update these recommendations. The main goal is to provide the pediatrician with the necessary tools to make a correct diagnosis, define the most appropriate treatment, select the patients who will benefit from antibiotic prophylaxis, and decide which imaging studies will be necessary, avoiding costly and invasive interventions. These guidelines also include the management of children with urinary tract infections associated with special situations such as: bladder bowel dysfunction, the newborn, children with neurogenic bladder, kidney transplant patients and fungal urinary tract infections.

En 2015 se publicaron en Archivos Argentinos de Pediatría las "Nuevas recomendaciones frente a las actuales controversias en infección urinaria". Dado que en estos años surgieron evidencias con respecto al diagnóstico, la forma de estudio y el tratamiento de la infección urinaria, el Comité de Nefrología Pediátrica de la Sociedad Argentina de Pediatría decidió actualizar dichas recomendaciones. El objetivo principal es brindar al pediatra las herramientas para realizar un correcto diagnóstico, definir el tratamiento más adecuado, seleccionar a los pacientes que se beneficiarán con la profilaxis antibiótica y decidir cuáles serán los estudios de imágenes necesarios, para evitar intervenciones costosas e invasivas. En estas guías se incluyen, además, los lineamientos para el manejo de niños con infecciones urinarias asociadas a situaciones especiales como la disfunción vesicointestinal, el recién nacido, los portadores de vejiga neurogénica, los receptores de trasplante renal y las infecciones urinarias micóticas.

The immune responses to different Uropathogens call individual interventions for bladder infection.

Urinary tract infection (UTI) caused by uropathogens is the most common infectious disease and significantly affects all aspects of the quality of life of the patients. However, uropathogens are increasingly becoming antibiotic-resistant, which threatens the only effective treatment option available-antibiotic, resulting in higher medical costs, prolonged hospital stays, and increased mortality. Currently, people are turning their attention to the immune responses, hoping to find effective immunotherapeutic interventions which can be alternatives to the overuse of antibiotic drugs. Bladder infections are caused by the main nine uropathogens and the bladder executes different immune responses depending on the type of uropathogens. It is essential to understand the immune responses to diverse uropathogens in bladder infection for guiding the design and development of immunotherapeutic interventions. This review firstly sorts out and comparatively analyzes the immune responses to the main nine uropathogens in bladder infection, and summarizes their similarities and differences. Based on these immune responses, we innovatively propose that different microbial bladder infections should adopt corresponding immunomodulatory interventions, and the same immunomodulatory intervention can also be applied to diverse microbial infections if they share the same effective therapeutic targets.
