Conclusiones: La mayoría de los pacientes diagnosticados con cáncer vesical corresponden al año 2019, masculinos, blancos, mayores de 70 o más años, fumadores y con hematuria. Más frecuente: el carcinoma urotelial papilar de bajo grado. El tiempo trascurrido antes del diagnóstico de la enfermedad fue de 36-40 días, y un mes, el tiempo trascurrido antes del tratamiento de la enfermedad.

Introduction: bladder cancer is one of the most frequent cancers of the urinary tract and manifests itself in two ways: as a superficial low-grade tumor or as a high-grade invasive neoplasm. Objective: to characterize bladder cancer in adults according to clinical, epidemiological and service variables. Methods: a descriptive and retrospective observational study was carried out to characterize bladder cancer in adults according to clinical, epidemiological and service variables of patients treated in the Urology service at "Arnaldo Milián Castro" Clinical and Surgical University Hospital from October 2019 and 2022. The study population was 242 patients diagnosed with bladder cancer. Results: most of the patients diagnosed with bladder cancer correspond to the year 2019 (45.86%): male (75.20%); whites (89.25%); older than 70 or more years (64.46%) and smokers (95.45%). Hematuria was the main symptom (91.73%), as an expression of low-grade papillary urothelial carcinoma (36.77%). The treatment was transurethral resection (88.01%), without distant metastasis (88.42%). Conclusions: most of the patients diagnosed with bladder cancer correspond to the year 2019, male, whites, older than 70 years or older, smokers and with hematuria. Low-grade papillary urothelial carcinoma was the most frequent cancer. The time elapsed before the diagnosis of the disease was 36-40 days, and the time elapsed before the treatment of the disease was 1 month.

Abstract Objective Analyze and synthesize the available scientific evidence on urinary catheterization and techniques used to prevent hematuria in bladder emptying and acute and chronic urinary retention in adults and the elderly. Methods This integrative review was carried out in the PubMed, LILACS, Embase, Cochrane, Web of Science, and Scopus databases. Hand searching was used in the reference lists of included studies. An unlimited period was used to review the studies published in Portuguese, English, French, German, and Spanish. The PICOS strategy was applied to develop the research question and the Joanna Briggs Institute (JBI) instrument was used to assess the methodological quality of studies. Results Eleven studies were included, with a total of 659 patients. Urinary retention occurred mainly in men and the main cause was benign prostatic hyperplasia. Rapid and gradual decompressions were the techniques used for bladder decompression by urinary catheterization, and hematuria and hypotension were the main complications regardless of the technique. The results showed that there was no significant difference between the two techniques in terms of the outcome of hematuria prevention. Conclusion Gradual bladder emptying does not prevent hematuria compared to rapid and complete emptying. Case reports describe clinical conditions that deserve attention when hematuria occurs after urinary catheterization and the respective implications in the treatment of patients. We highlight the importance of nursing in identifying and preventing the diagnosis of Urinary Retention to avoid subsequent interventions and clinical complications, including post-catheterization hematuria.

Factores de riesgo asociados al cáncer vesical en pacientes adultos / Risk factors associated with bladder cancer in adult patients

Introducción: El cáncer vesical es una enfermedad que afecta, generalmente, a pacientes masculinos de la tercera edad. Este tumor tiene dos formas principales de manifestarse: como tumor superficial y de bajo grado, o como neoplasia invasora de alto grado. La mayoría de los pacientes afectados con esta enfermedad presentan como factor de riesgo, el consumo de tabaco. Objetivo: Contribuir al conocimiento de la comunidad científica en lo relativo a los factores de riesgo y al síntoma principal asociados al cáncer vesical en pacientes adultos de la tercera edad. Métodos: Se realizó una revisión sistemática sobre el tema en las bases de datos: SciELO, EBSCO, Scopus, PubMed, y en revistas de Urología. Los artículos fueron publicados en idioma español o inglés. Se realizó un análisis del contenido para lograr la actualización teórica del tema. Conclusiones: El cáncer vesical es una enfermedad multifocal que provoca la aparición de varias neoformaciones dentro del epitelio transicional, en toda su extensión. La presencia de hematuria asintomática en los pacientes adultos fue la causa más común de consulta con el urólogo. Dentro de los factores de riesgo, el principal fue el consumo de tabaco.

Introduction: bladder cancer is a disease that generally affects elderly male patients. This tumour has two main forms of manifestation: as a low-grade superficial tumor or as a high-grade invasive neoplasm. Most of the patients affected with this disease have tobacco consumption as a risk factor. Objective: to contribute to the knowledge of the scientific community in relation to the risk factors associated with bladder cancer in elderly patients. Methods: a systematic review on the subject was carried out in SciELO, EBSCO, Scopus and PubMed databases as well as in Urology journals. Articles published in Spanish or English languages were taken into account. A content analysis was conducted to achieve a theoretical update on this topic. Conclusions: bladder cancer is a multifocal disease that causes the appearance of several neoformations within the transitional epithelium and throughout its entire length. The presence of asymptomatic hematuria in adult patients was the most common reason for consultation with the urologist. The main risk factor was tobacco consumption.

Dynamic and static ultrasound features predictive of vesicoureteral reflux and renal damage in children and adolescents with neurogenic bladder

ABSTRACT Purpose: This study aimed to analyze the diagnostic accuracy of dynamic and static ultrasound (DSUS) in detecting vesicoureteral reflux (VUR) and renal scarring in a cohort of children with neurogenic bladder (NB). Materials and Methods: A retrospective, longitudinal, observational study was conducted using the Reporting Diagnostic Accuracy Studies guideline. The DSUS (index test) data were compared with voiding cystourethrography (VCUG) and renal scintigraphy 99mTc-dimercaptosuccinic (reference tests). Overall performance for predicting VUR and renal scarring was assessed using renal pelvic diameter (RPD)/distal ureteral diameter and renal parenchymal thinning on DSUS, respectively. Results: A total of 107 patients (66 girls, median age 9.6 years) participated. Seventeen patients (15.9%) presented VUR, eight bilateral. For overall reflux grade, the AUC was 0.624 for RPD and 0.630 for distal ureteral diameter. The diagnostic performance for detecting high-grade VUR was slightly better for DSUS parameters. The AUC was 0.666 for RPD and 0.691 for distal ureteral diameter. The cut-offs of 5 mm for RPD and 6.5 mm for distal ureteral diameter presented the best diagnostic odds ratio (DOR) to identify high-grade VUR. The increase of RPD during detrusor contractions showed an accuracy of 89.2%. The thinness of renal parenchyma presented an accuracy of 88% for renal scarring. Conclusion: DSUS predicts VUR and renal scarring in children with NB with fair to good accuracy, and all measurements exhibited a high negative predictive value (NPV). The increase in RPD during voiding or detrusor contractions proved to be the most accurate parameter for indicating the presence of VUR in this study.

Urological knowledge and tools applied to diagnosis and surgery in deep infiltrating endometriosis - a narrative review

ABSTRACT Objectives: This review discusses deep infiltrating endometriosis (DIE) diagnosis and surgery using current urological knowledge and technologies. Materials and Methods: Narrative review of deep infiltrating endometriosis that result in urological issues. We examined manuscripts from Pubmed, Embase, and Scielo's database using the following MeSH terms: ('endometriosis') AND ('urology' OR 'urological' OR 'urologist') AND ('bladder' OR'vesical') AND ('ureteral' OR 'ureter'). Selection followed PRISMA guidelines. Sample images from our records were brought to endorse the findings. Results: Thirty four related articles were chosen from 105. DIE may affect the urinary system in 52.6% of patients. Lower urinary tract symptoms may require urodynamic examination. Ultrasonography offers strong statistical yields for detecting urinary tract lesions or distortions, but magnetic resonance will confirm the diagnosis. Cystoscopy can detect active lesions, although any macroscopic visual appeal is pathognomonic. Endourology is utilized intraoperatively for bladder and ureteral assessment, however transurethral endoscopic excision of bladder lesions had higher recurrence rates. Laparoscopy is the route of choice for treatment; partial cystectomy, and bladder shaving were the most prevalent surgical treatments for bladder endometriosis. Regarding the ureteral treatment, the simple ureterolysis and complex reconstructive techniques were described in most papers. Using anatomical landmarks or neuronavigation, pelvic surgical systematization allows intraoperative neural structure identification. Conclusions: DIE in the urinary system is common, however the number of publications with high level of evidence is limited. The initial tools for diagnosis are ultrasonography and cystoscopy, but magnetic resonance is the most reliable tool. When the patient has voiding symptoms, the urodynamic examination is crucial. Laparoscopy improves lesion detection and anatomical understanding. This approach must be carried out by professionals with high expertise, since the surgery goes beyond the resection of lesions and includes the preservation of nerve structures and urinary tract reconstruction techniques.

Comparative assessment of efficacy and safety of approved oral therapies for overactive bladder: a systematic review and network meta-analysis

ABSTRACT Purpose: To compare the effectiveness and safety of marketed oral drugs for overactive bladder based on a systematic review and network meta-analysis approach. Methods: Pubmed, Embase, Web of Science, and the Cochrane Register of Clinical Trials databases were systematically searched. The search time frame was from database creation to June 2, 2022. Randomized controlled double-blind trials of oral medication for overactive bladder were screened against the protocol's entry criteria. Trials were evaluated for quality using the Cochrane Risk of Bias Assessment Tool, and data were statistically analyzed using Stata 16.0 software. Result: A total of 60 randomized controlled double-blind clinical trials were included involving 50,333 subjects. Solifenacin 10mg was the most effective in mean daily micturitions and incontinence episodes, solifenacin 5/10mg in mean daily urinary urgency episodes and nocturia episodes, fesoterodine 8mg in urgency incontinence episodes/d and oxybutynin 5mg in voided volume/micturition. In terms of safety, solifenacin 5mg, ER-tolterodine 4mg, mirabegron, vibegron and ER-oxybutynin 10mg all showed a better incidence of dry mouth, fesoterodine 4mg, ER-oxybutynin 10mg, tolterodine 2mg, and vibegron in the incidence of constipation. Compared to placebo, imidafenacin 0.1mg showed a significantly increased incidence in hypertension, solifenacin 10mg in urinary tract infection, fesoterodine 4/8mg and darifenacin 15mg in headache. Conclusion: Solifenacin showed better efficacy. For safety, most anticholinergic drugs were more likely to cause dry mouth and constipation, lower doses were better tolerated. The choice of drugs should be tailored to the patient's specific situation to find the best balance between efficacy and safety.

Effects of different combinations of radical nephroureterectomy and bladder cuff excision procedures for upper tract urothelial carcinoma on bladder recurrence

ABSTRACT Purpose: To compare the effects of different combinations of radical nephroureterectomy (RNU) and bladder cuff excision (BCE) surgical procedures on intravesical recurrence (IVR) in patients with upper tract urothelial carcinoma (UTUC). Materials and Methods: This retrospective observational study included 452 patients who underwent RNU with BCE for UTUC between January 2010 and December 2020. The patients were classified into three groups based on different combinations of RNU and BCE surgical procedures: open RNU with open BCE (group 1, n=104), minimally invasive (MIS) RNU with open BCE (group 2, n=196), and MIS RNU with intracorporeal BCE (group 3, n=152). Data on demographics, body mass index, history, preoperative renal function, perioperative status, tumor characteristics, histopathology, and recurrence conditions were collected. Multivariate Cox regression analyses were performed to determine the impact of the surgical procedures on IVR. P-values <0.05 were considered statistically significant. Results: After a median follow-up of 29.5 months, the IVR rate was 29.6% and the IVR-free survival rate was the lowest in group 2 (group 1 vs. group 2 vs. group 3: 69.0% vs. 55.1% vs. 67.5%; log-rank P=0.048). The overall survival rate was comparable among the three groups. Multivariate analysis revealed that group 2 had a significantly higher risk of IVR than group 1 (hazard ratio=1.949, 95% confidence interval=1.082-3.511, P=0.026), while groups 1 and 3 had similar risks. Conclusions: For patients with UTUC, MIS RNU with open BCE is associated with a higher risk of IVR than open RNU with open BCE and MIS RNU with intracorporeal BCE.

Perioperative mortality for radical cystectomy in the modern Era: experience from a tertiary referral center

ABSTRACT Purpose To evaluate the perioperative mortality and contributing variables among patients who underwent radical cystectomy (RC) for bladder cancer in recent decades, with comparison between modern (after 2010) and premodern (before 2010) eras. Materials and Methods Using our institutional review board-approved database, we reviewed the records of patients who underwent RC for primary urothelial bladder carcinoma with curative intent from January 2003 to December 2019. The primary and secondary outcomes were 90- and 30-day mortality. Univariate and multivariable logistic regression models were applied to assess the impact of perioperative variables on 90-day mortality. Results A total of 2047 patients with a mean±SD age of 69.6±10.6 years were included. The 30- and 90-day mortality rates were 1.3% and 4.9%, respectively, and consistent during the past two decades. Among 100 deaths within 90 days, 18 occurred during index hospitalization. Infectious, pulmonary, and cardiac complications were the leading mortality causes. Multivariable analysis showed that age (Odds Ratio: OR 1.05), Charlson comorbidity index ≥ 2 (OR 1.82), blood transfusion (OR 1.95), and pathological node disease (OR 2.85) were independently associated with 90-day mortality. Nevertheless, the surgical approach and enhanced recovery protocols had no significant effect on 90-day mortality. Conclusion The 90-day mortality for RC is approaching five percent, with infectious, pulmonary, and cardiac complications as the leading mortality causes. Older age, higher comorbidity, blood transfusion, and pathological lymph node involvement are independently associated with 90-day mortality.

Urinary retention after lipoabdominoplasty: case report / Retenção urinária após lipoabdominoplastia: relato de caso

Introduction: Postoperative urinary retention may predispose to permanent bladder damage. Risk factors include type of anesthesia, type of surgery, and use of anticholinergics, analgesics, and opioids. Once the lesion is established, complementary urodynamic tests are essential for etiological diagnosis and treatment. The objective of this study is to report a case of a patient with urinary retention in the postoperative period of lipoabdominoplasty. Case Report: 27-year-old female patient, without comorbidities or use of continuous medication. She underwent lipoabdominoplasty and evolved postoperatively with urinary retention and bladder distention, diagnosed as detrusor contractility and sensitivity deficit in the urodynamic study. She was maintained in outpatient follow-up with the surgical team and Urology, with a progressive reduction in urinary catheter use and complete removal in eight months of follow-up. Discussion: The objective of aesthetic plastic surgery is to improve the physical appearance of the body. It is subject to complications like other surgical procedures, and pain seems to be the most frequent. Urinary retention may be secondary to the use of opioids, and its diagnosis in the postoperative period of lipoabdominoplasty still has some obstacles. Plication of the rectus muscle diastasis, liposuction, and the use of a compressive abdominal belt make it difficult to identify a possible bladder distention. An episode of bladder overdistention can result in significant morbidity. Conclusion: The present report demonstrated the good evolution of a patient who developed urinary retention in the postoperative period of lipoabdominoplasty. The main diagnostic hypothesis was that it was secondary to the use of opioids.

Introdução: A retenção urinária pós-operatória pode predispor a danos permanentes à bexiga. Os fatores de risco incluem tipo de anestesia, tipo de cirurgia e uso anticolinérgicos, analgésicos e opioides. Uma vez que a lesão está estabelecida, os exames complementares urodinâmicos são fundamentais para diagnóstico etiológico e tratamento. O objetivo deste trabalho é relatar caso de paciente com quadro de retenção urinária no pós-operatório de lipoabdominoplastia. Relato de Caso: Paciente de 27 anos, sexo feminino, sem comorbidades ou uso de medicamentos contínuos. Foi submetida a lipoabdominoplastia, e evoluiu no pós-operatório com quadro de retenção urinária e bexigoma, diagnosticada como acontratilidade detrusora e déficit de sensibilidade no estudo urodinâmico. Manteve acompanhamento ambulatorial com a equipe cirúrgica e a Urologia, com redução progressiva do uso do cateter vesical e retirada completa em oito meses de seguimento. Discussão: O objetivo da cirurgia plástica estética é melhorar o aspecto físico do corpo. Como os demais procedimentos cirúrgicos, está sujeita a complicações e a dor parece ser a mais frequente. A retenção urinária pode ser secundária ao uso de opioides e seu diagnóstico no pós-operatório da lipoabdominoplastia ainda possui alguns obstáculos. A plicatura da diástase do músculo reto, a lipoaspiração e o uso de cinta abdominal compressiva dificultam a identificação do possível bexigoma. Um episódio de hiperdistensão da bexiga pode resultar em morbidade significativa. Conclusão: O presente relato demonstrou boa evolução de paciente que desenvolveu retenção urinária no pós-operatório de lipoabdominoplastia. A principal hipótese diagnóstica foi de ser secundária ao uso de opioide.

Diagnóstico y tratamiento de pacientes con vejiga neurogénica en la Unidad Técnica de Cirugía Pediátrica / Diagnosis and treatment of patients with Neurogenic bladder in the Surgery Technical Unit Pediatric

El presente trabajo toma como base el documento: "Manejo Urológico del Mielomeningocele" de las Guías de Atención Pediátrica, del Hospital De Pediatría "Juan P. Garrahan" de la ciudad de Buenos Aires - Argentina; de los autores: Dra. Carol Burek y Dra. Liliana Campmany. En la Unidad Técnica de Cirugía Pediátrica del Hospital de Especialidades Carlos Andrade Marín, se atienden por mes unos 50 a 70 pacientes afectos de vejiga neurogénica desde el nacimiento hasta la adolescencia. Es una enfermedad crónica que requiere un diagnóstico correcto con estudios de imagen y función de la vía urinaria además de un posterior manejo diario por parte de los padres con la guía del médico especialista.

This work is based on the document: "Urological Management of Myelomeningocele" from the Pediatric Care Guidelines of the Hospital De Pediatría "Juan P. Garrahan" of the city of Buenos Aires - Argentina; by the authors: Dr. Carol Burek and Dr. Liliana Campmany. In the Pediatric Surgery Technical Unit of the Carlos Andrade Marín Specialties Hospital, 50 to 70 patients affected by neurogenic bladder from birth to adolescence are treated every month. It is a chronic disease that requires a correct diagnosis with imaging and urinary tract function studies, as well as subsequent daily management by the parents under the guidance of the specialist.

Dynamic cystoscopy to optimize preoperative assessment of bladder endometriosis

ABSTRACT Purpose Bladder endometriosis (BE) accounts for 84% of cases of urinary tract involvement. The use of cystoscopy for preoperative evaluation is limited. The aim of this study was to evaluate the accuracy of preoperative dynamic cystoscopy (DC) in patients undergoing surgery for deep endometriosis and to describe the main findings and their impact on surgical planning. Materials and Methods This cross-sectional observational study was conducted from January 2011 to March 2022. DC findings were divided into two groups according to the depth of involvement. To estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), laparoscopic findings of bladder involvement and histopathological report were used as the gold standard. Results We included 157 patients in this study. 41 had abnormalities in DC. Of these, 39 had abnormalities that were confirmed intraoperatively. The sensitivity and specificity of the test were 58.21% and 97.78%, respectively. PPV was 95.12%, and NPV was 75.86%. The presence of any lesions in the DC had a diagnostic odds ratio (OR) of 61.28 for BE. Patients with BE type 2 had a higher rate of partial cystectomy than those with BE type 1 lesions (OR 9.72 CI 95% 1.9-49.1) Conclusion DC appears to be a highly specific test with lower sensitivity. DC abnormalities are associated with a higher ratio of bladder surgery for the treatment of deep endometriosis, and BE type 2 seems to be associated with a greater ratio (9.72) of partial cystectomy.

Epitheloid hemangioendothelioma of the urinary bladder: A case report of a rare entity

Epithelioid hemangioendothelioma (EHE) is a rare, often multifocal, intermediate-grade vascular sarcoma arising from the endothelial cells. Their behavior is intermediate between hemangioma and conventional angiosarcoma. Their rarity and unpredictable clinical behavior result in our still limited understanding and treatment options for this variety of tumors. Molecular diagnostic tools like the presence of WWTR1-CAMTA1 fusion have been developed to aid this challenging diagnosis. There is no definitive consensus on the management of patients with this disease and no commonly accepted treatment strategies have been found to be effective, particularly in the metastatic setting. When possible, surgery with clear margins should be considered in case of localized disease. Here, we not only present such a rare case of EHE of the urinary bladder but also provide a comprehensive discussion on the present treatment modalities offered, as found through a thorough search of the published studies. Finally, more studies are required to establish a standard of care for this rare entity

Validation of the Vancouver Symptom Score Questionnaire for bladder and bowel dysfunction for Brazilian children and adolescents

ABSTRACT Objective: This study aimed to translate, and perform a cross-cultural adaptation, and validation of the Vancouver Symptom Score (VSS) for bladder and bowel dysfunction (BBD) for Brazilian children and adolescents Materials and Methods: Six steps were performed for the translation and cross-cultural adaptation: (1) translation, (2) synthesis of translations, (3) back-translation, (4) pre-final version of the translated instrument, (5) pilot test and degree of comprehensibility and (6) elaboration of the Brazilian version of the VSS. For validation, the Brazilian Dysfunctional Voiding Score (DVSS) questionnaire was used. Results: Validation was performed on a sample of 107 children and adolescents with a mean age of 9.2 ± 2.84 years, presenting BBD and 107 without BBD (control group-CG). There was a positive correlation (r = 0.91, 95% CI 0.88 to 0.93, p < 0.0001) between total VSS score and total DVSS score. VSS was higher in patients with BBD (p < 0.0001). The internal consistency estimated by Cronbach's alpha was 0.87 for patients with BBD. The VSS showed excellent diagnostic accuracy in detecting cases, with an area under the ROC curve of 98% (95% CI 0.96 to 0.99, p < 0.001). A cut-off value of >11 points produced a sensitivity of 100% (95% CI 96.4% to 100%) and a specificity of 91.8% (95% CI 85.1% to 95.6%). Conclusion: The translated, cross-culturally adapted, and validated VSS for the Brazilian population is a reliable and valid tool to identify symptoms of BBD in children and adolescents aged five to 16 years, whose first language is Brazilian Portuguese.

Identification and validation of a novel prognostic model based on platinum resistance-related genes in bladder cancer

ABSTRACT Background: The depth of response to platinum in urothelial neoplasm tissues varies greatly. Biomarkers that have practical value in prognosis stratification are increasingly needed. Our study aimed to select a set of BC (bladder cancer)-related genes involved in both platinum resistance and survival, then use these genes to establish the prognostic model. Materials and Methods: Platinum resistance-related DEGs (differentially expressed genes) and tumorigenesis-related DEGs were identified. Ten most predictive co-DEGs were acquired followed by building a risk score model. Survival analysis and ROC (receiver operating characteristic) plot were used to evaluate the predictive accuracy. Combined with age and tumor stages, a nomogram was generated to create a graphical representation of survival rates at 1-, 3-, 5-, and 8-year in BC patients. The prognostic performance was validated in three independent BC datasets with platinum-based chemotherapy. The potential mechanism was explored by enrichment analysis. Results: PPP2R2B, TSPAN7, ATAD3C, SYT15, SAPCD1, AKR1B1, TCHH, AKAP12, AGLN3, and IGF2 were selected for our prognostic model. Patients in high- and low-risk groups exhibited a significant survival difference with HR (hazard ratio) = 2.7 (p < 0.0001). The prognostic nomogram of predicting 3-year OS (overall survival) for BC patients could yield an AUC (area under the curve) of 0.819. In the external validation dataset, the risk score also has a robust predictive ability. Conclusion: A prognostic model derived from platinum resistance-related genes was constructed, we confirmed its value in predicting platinum-based chemotherapy benefits and overall survival for BC patients. The model might assist in therapeutic decisions for bladder malignancy.

Abstract Objective To describe the sociodemographic profile, access and interest in receiving online information about bladder and bowel dysfunction as well as understand the experience of families of children and adolescents affected by this dysfunction. Methods This is a multi-methodological study carried out in an outpatient clinic of Advanced Nursing Practice in uropediatrics of a teaching hospital in midwestern Brazil. Results The experience of families of children with bladder and bowel dysfunction points to a negative impact on everyday life, which may be related to sociodemographic conditions, lack of knowledge of families about the symptoms and stigmas associated with its manifestation. To this end, access to online information is a potential support tool to improve the experience of children's families with the symptoms. Conclusion The results express children's sociodemographic characterization and their family and the access and interest in receiving information on the internet about bladder and bowel dysfunction, which may be important for compliance and perception of improvement in symptoms, reflecting on family experience. Therefore, nurses who work in the context of uropediatrics care need to innovate in their approach and implement new care modalities or health interventions, mainly through the incorporation of internet-based technologies, aimed at improving the quality of life of both the families and children with bladder and bowel dysfunction.

Association of human papillomavirus (HPV), p16, p53 and p63 expression with non-bilharzia-associated squamous cell carcinoma of the bladder and algorithm construction for histopathological grading prediction

ABSTRACT Objective To investigate the expression of human papillomavirus (HPV), p16, p53, and p63 in non-schistosomiasis-related squamous cell carcinoma of the bladder and to develop an accurate and automated tool to predict histological classification based on clinicopathological features. Methods Twenty-eight patients with primary bladder pure squamous cell carcinoma who underwent cystectomy or transurethral resection of bladder tumor (TURBT) for bladder cancer between January 2011 and July 2017 were evaluated. Clinical data and follow-up information were obtained from medical records. Formalin-fixed, paraffin-embedded surgical specimens were used for immunohistochemical staining for p16, p53, and p63. Human papillomavirus detection was evaluated by PCR. Statistical analysis was performed, and statistical significance was set at p<0.05. Finally, decision trees were built to classify patients' prognostic features. Leave-one-out cross-validation was used to test the generalizability of the model. Results Neither direct HPV detection nor its indirect marker (p16 protein) was identified in most cases. The absence of p16 was correlated with less aggressive histological grading (p=0.040). The positive p16 staining detection found only in pT1 and pT2 cases in our sample suggests a possible role for this tumor suppressor protein in the initial stages of bladder squamous cell carcinoma. The decision trees constructed described the relationship between clinical features, such as hematuria/dysuria, the level of tumor invasion, HPV status, lymphovascular invasion, gender, age, compromised lymph nodes, and tumor degree differentiation, with high classification accuracy. Conclusion The algorithm classifier approach established decision pathways for semi-automatic tumor histological classification, laying the foundation for tailored semi-automated decision support systems for pathologists.

Desenvolvimento e validação de conteúdo da intervenção "ultrassonografia: bexiga" de acordo com a nursing interventions classification (NIC) / Desarrollo y validación de contenido de laIntervención "Ultrasonografía: Vejiga" según la Nursing Interventions Classification (NIC) / Development and content validation of the Intervention "Ultrasonography: bladder" according to the Nursing Interventions Classification (NIC)

Introdução: Os problemas urinários, como retenção e incontinência urinária, são recorrentes na prática clínica, sendo condições sensíveis à enfermagem, que necessitam de identificação e correção oportunas. Nesse sentido, a ultrassonografia (USG) de bexiga realizada por enfermeiros permite uma avaliação vesical acurada e não invasiva, sendo descrito seu uso na literatura de enfermagem desde a década de 80. Todavia, ao analisar a Classificação das Intervenções de Enfermagem (NIC), nota-se que não constam descritas intervenções com uso da USG de bexiga por enfermeiros. Objetivo: Realizar o desenvolvimento e a validação de conteúdo de uma nova Intervenção de Enfermagem com o uso de USG de bexiga segundo a NIC. Método: Trata-se de um estudo metodológico em três etapas: Revisão integrativa de literatura (RIL); Desenvolvimento da intervenção; Validação de conteúdo. Na Etapa da RIL, foram realizadas buscas nas bases de dados Cumulative Index to Nursing and Allied Health Literature (CINAHL), SCOPUS (Elsevier), National Library of Medicine (PubMed) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), sem limitação temporal, nos idiomas inglês, português e espanhol. Na segunda etapa, a intervenção foi desenvolvida de acordo com os achados da RIL, seguindo passos teóricos preconizados pela NIC. Na terceira etapa a intervenção foi submetida à validação de conteúdo por especialistas em dois momentos: formulários virtuais e grupo focal. A amostra foi estimada em 22 especialistas para etapa de formulários virtuais, com uma proporção de concordância mínima de 85% e um nível de confiança de 95%. A concordância na primeira etapa da validação foi analisada a partir do Teste Binomial, sendo considerado válido aquele item que obtivesse um valor de p maior que 0,05. Os itens que não obtivessem concordância suficiente foram avaliados em grupo focal para adequação ou exclusão da Intervenção desenvolvida. A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa da Universidade Federal do Rio Grande do Sul (CAEE 61922422.80000.5347). Resultados: Foram apresentados sob a forma de dois artigos, no primeiro encontram-se descritas as duas primeiras etapas (RIL e desenvolvimento da intervenção) e no segundo, a validação de conteúdo. A RIL incluiu 17 artigos, destacando-se estudos descritivos, o que possibilitou o desenvolvimento da Intervenção de Enfermagem "Ultrassonografia: bexiga", com 21 itens (Título, Definição, 17 Atividades, Nível de Formação e Tempo Estimado para Realização da Intervenção). Esse primeiro construto teórico foi submetido ao Comitê Editorial da NIC e aceito para inclusão na próxima edição da Classificação. O segundo artigo contém a validação de conteúdo dessa intervenção, onde 18 itens foram validados na etapa dos formulários virtuais e os três itens que não alcançaram a concordância mínima foram validados mediante alterações realizadas a partir de avaliação de três especialistas em grupo focal. Considerações finais: O presente estudo desenvolveu e validou o conteúdo de uma nova Intervenção de Enfermagem de acordo com a NIC, intitulada "Ultrassonografia: bexiga". Essa intervenção constará na oitava edição da NIC, com publicação prevista para 2023. Recomendam-se outros estudos com maior robustez científica, visando à comprovação clínica dos achados teóricos aqui descritos.

Introduction: Urinary problems, such as urinary retention and incontinence, are recurrent in clinical practice, being nursing sensitive conditions that require timely identification and correction. In this sense, bladder ultrasonography (USG) performed by nurses allows an accurate and non-invasive bladder evaluation, and its use has been described in the nursing literature since the 1980s. However, when analyzing the Nursing Interventions Classification (NIC), it is noted that there are no descriptions of interventions with the use of USG of the bladder by nurses. Objective: To carry out the development and content validation of a new Nursing Intervention with the use of USG of the bladder according to the NIC. Method: This is a methodological study in three stages: integrative literature review (ILR); Intervention development; Content validation. In the ILR stage, searches were carried out in the Cumulative Index to Nursing and Allied Health Literature (CINAHL), SCOPUS (Elsevier), National Library of Medicine (PubMed) and Latin American and Caribbean Literature in Health Sciences (LILACS) databases, without time limitation, in English, Portuguese and Spanish. In the second stage, the intervention was developed according to the ILR findings, following theoretical steps recommended by the NIC. In the third stage, the intervention was submitted to content validation by specialists in two moments: virtual forms and focus group. The sample was estimated at 22 specialists for the virtual forms stage, with a minimum agreement proportion of 85% and a confidence level of 95%. Agreement in the first stage of validation was analyzed using the Binomial Test, with an item that obtained a p-value greater than 0.05 being considered valid. Items that did not obtain sufficient agreement were evaluated in a focus group for adequacy or exclusion from the developed Intervention.The research was approved by the Research Ethics Committee of the Federal University of Rio Grande do Sul (CAEE 61922422.80000.5347). Results: They were presented in the form of two articles, in the first the first two stages are described (ILR and development of the intervention) and in the second, the content validation. The ILR included 17 articles, with emphasis on descriptive studies, which enabled the development of the Nursing Intervention "Ultrasonography: bladder", with 21 items (Title, Definition, 17 Activities, Level of Training and Estimated Time for Carrying Out the Intervention). This first theoretical construct was submitted to the NIC Editorial Committee and accepted for inclusion in the next edition of the Classification. The second article contains the content validation of this intervention, where 18 items were validated in the virtual forms stage and the three items that did not reach the minimum agreement were validated through changes made from the evaluation of three specialists in a focus group. Final considerations: The present study developed and validated the content of a new Nursing Intervention according to the NIC, entitled "Ultrasound: bladder". This intervention will appear in the eighth edition of the NIC, with publication scheduled for 2023. Further studies with greater scientific robustness are recommended, aiming at clinically proving the theoretical findings described here.

La muestra se estimó en 22 especialistas para la etapa de formularios virtuales, con una proporción mínima de acuerdo del 85% y un nivel de confianza del 95%. La concordancia en la primera etapa de validación se analizó mediante el Test Binomial, considerándose válido el ítem que obtuviera un p-valor superior a 0,05. Los ítems que no obtuvieron suficiente acuerdo fueron evaluados en un grupo focal para su adecuación o exclusión de la Intervención desarrollada. La investigación fue aprobada por el Comité de Ética en Investigación de la Universidade Federal do Rio Grande do Sul (CAEE 61922422.80000.5347). Resultados: Se presentaron en forma de dos artículos, en el primero se describen las dos primeras etapas (RIL y desarrollo de la intervención) y en el segundo, la validación de contenido. La RIL incluyó 17 artículos, con énfasis en estudios descriptivos, que posibilitaron el desarrollo de la Intervención de Enfermería "Ultrasonografía: vejiga", con 21 ítems (Título, Definición, 17 Actividades, Nivel de Entrenamiento y Tiempo Estimado para Realización de la Intervención). Este primer constructo teórico fue presentado al Comité Editorial de la NIC y aceptado para su inclusión en la próxima edición de la Clasificación. El segundo artículo contiene la validación de contenido de esta intervención, donde se validaron 18 ítems en la etapa de formularios virtuales y los tres ítems que no alcanzaron el acuerdo mínimo se validaron mediante cambios realizados a partir de la evaluación de tres especialistas en un grupo focal. Consideraciones finales: El presente estúdio desarrolló y validó el contenido de una nueva Intervención de Enfermería según la NIC, titulada "Ultrasonido: vejiga". Esta intervención aparecerá en la octava edición de la NIC, con publicación prevista para 2023. Se recomiendan más estudios con mayor solidez científica, con el objetivo de probar clínicamente los hallazgos teóricos aquí descritos.
