Translation and cross-cultural adaptation of the Childhood Bladder and Bowel Dysfunction Questionnaire (CBBDQ)

Abstract Objective: To translate and cross-culturally adapt the Childhood Bladder and Bowel Dysfunction Questionnaire (CBBDQ) for use in Brazilian Portuguese. The CBBDQ is an 18-item tool covering 10 bladder and 8 bowel symptoms that was developed for use with children of 5 to 12 years of age with bowel and bladder dysfunction (BBD). The instrument has already been validated for use in Dutch and English. Method: In the process of translation and cultural adaptation from English to Portuguese, the CBBDQ was submitted to undergo the required steps as established by the international methodological criteria: forward translation, synthesis, back-translation, expert panel review and pre-testing. Results: Ninety-three parents of children with lower urinary tract dysfunction answered the questionnaire. The mean age of the children was 7.6 ± 2.1 years and 54 were female. Internal consistency was excellent, with a Cronbach's alpha of 0.91 to 0.96. Additionally, reliability was high, with an intraclass correlation coefficient of 0.94 (95%CI: 0.85-0.93; p < 0.0001). Conclusion: The translation and cultural adaptation of the CBBDQ enabled a quantitative evaluation of bladder and bowel symptoms to be performed in Brazilian children. The scores achieved allow the severity of BBD to be evaluated, as well as the patient's progress during treatment. The use of this questionnaire in clinical practice and research will allow more consistent data on BBD to be obtained.

Prevalence of Bladder and Bowel Dysfunction in the Outpatient Clinic of Pediatric Urology and Nephrology / Prevalencia de la disfunción de la vejiga y del intestino en la consulta ambulatoria de urología y nefrología pediátrica

Zoom Image Abstract Objective Bladder and bowel dysfunction (BBD) is defined as the presence of functional alterations in both organs. The correct diagnosis and treatment prevent the exposure of patients to multiple antibiotic treatments, invasive procedures and radiological studies. The aim of the present study was to estimate the prevalence of BBD in the outpatient clinic of pediatric urology and nephrology. Methods A prospective cohort composed of 334 patients aged between 5 and 18 years was evaluated. The Pediatric Lower Urinary Tract Symptom Score (PLUTSS) was applied. A score higher than 8 was considered as significant urinary symptomatology. Moreover, the Bristol Stool Scale and the Rome IV Criteria for functional constipation and fecal incontinence were used. Patients with organic pathologies were excluded. The risk factors were evaluated using logistic regression models. Results The median age was 9 years old (interquartile range [IQR]: 6­13). The PLUTSS questionnaire was significant in 16.5% of the kids, constipation was found in 31.9%, and fecal incontinence, in 4%. The prevalence of BBD was of 27.8%. The female gender (odds ratio [OR]: 2.47; p = 0.002) and psychological disorders (OR: 4.637; p = 0.024) were considered risk factors. The evaluation of the PLUTSS questionnaire showed relevance regarding incontinence (OR: 3.059; p = 0.038), enuresis (OR: 8.532; p < 0.001); intermittent flow (OR: 9.211; p = 0.004), frequency (OR: 6.73; p = 0.005), and constipation (OR: 34.46; p < 0.001). Conclusions The prevalence of BBD is of 27.8% in the outpatient clinic. It is important to prevent associated complications and the exposure to multiple antibiotic treatments, as well as invasive and imaging procedures, which also generate high costs to the health system.

Resumen Objetivo El síndrome de disfunción de la vejiga y del intestino (DVI) se define como la presencia de alteraciones funcionales en ambos órganos. El correcto diagnóstico y tratamiento previene la exposición de los pacientes a múltiples manejos antibióticos, procedimientos invasivos y estudios radiológicos. El objetivo de este estudio es estimar la prevalencia de DVI en la consulta ambulatoria de urología y nefrología pediátrica. Métodos Se evaluó una cohorte prospectiva de 334 pacientes de 5 a 18 años. Se aplicó el cuestionario de Puntuación de Síntomas del Tracto Urinario Inferior (Pediatric Lower Urinary Tract Symptom Score, PLUTSS), cuyo resultado mayor a 8 fue considerado significativo. Adicionalmente, se usó la Escala de Heces de Bristol (Bristol Stool Scale) y los Criterios Roma IV (Rome IV Criteria) para estreñimiento e incontinencia fecal. Los factores de riesgo se evaluaron bajo modelos de regresión logística. Resultados La edad mediana fue de 9 años (rango intercuartil [RIC]: 6­13). El cuestionario PLUTSS fue significativo en 16,5% de los niños, y se observó estreñimiento en 31,9%, e incontinencia fecal en 4%. La prevalencia de DVI fue de 27,8%. El sexo femenino (razón de probabilidades [RP]: 2.47; p = 0.002) y desordenes psicológicos (RP: 4.637; p = 0.024) fueron considerados factores de riesgo. La evaluación del cuestionario PLUTSS mostró relevancia en incontinencia (RP: 3.059; p = 0.038), enuresis (RP: 8.532; p < 0.001), flujo intermitente (RP: 9.211; p = 0.004), frecuencia (RP: 6.73; p = 0.005), y estreñimiento (RP: 34.46; p < 0.001). Conclusiones La prevalencia de DVI fue de 27.8% en la consulta ambulatoria. Es importante prevenir complicaciones asociadas y la exposición a múltiples tratamientos antibióticos, procedimientos invasivos e imagenológicos, que adicionalmente generan altos costos al sistema de salud.
