E.5 End points |
E.5.1 | Primary end point(s) |
Occurrence of a relevant reduction (equal or greater than 50%) in any of the 3 main signs of SVHI (urinary frequency, diurnal / nocturnal frequency, urgency and urinary incontinence). The three signs will be measured with a voiding diary of 3 days in the baseline study weeks and the completion of the first and third month. 3-day urination diaries are a reliable tool and have been shown to be sensitive to change.
The 3-day voiding diary (DM3d) has been validated in Spain in the evaluation of STUI in women, and is available through the website of the Spanish Association of Urology |
Ocurrencia de una reducción relevante (igual o mayor del 50%) en alguno de los 3 signos principales del SVHI (frecuencia miccional diurna/nocturna, urgencia e incontinencia urinaria). Los tres signos se medirán con un diario miccional de 3 días en las semanas del estudio basal y la que se cumplan el primer y tercer mes. Los diarios miccionales de 3 días son una herramienta fiable y que han mostrado ser sensibles al cambio .
El diario miccional de 3 días (DM3d) ha sido validado en España en la evaluación de STUI en mujeres, y se encuentra disponible a través de la página de la Asociación Española de Urología. |

E.5.1.1 | Timepoint(s) of evaluation of this end point |
During three days the three following months |

|
E.5.2 | Secondary end point(s) |
1. Urodynamic changes occurring at 3 months in relation to the following parameters: (i) Mical volume at which the first uninhibited contraction originates, in case of detrusoric hyperactivity; (Ii) extent of uninhibited contractions; (Iii) Total bladder capacity (iv) Post-admixture; V) Flowmetry: Qmax, mean Q, time of urination. All these parameters will be measured with instruments calibrated and available in each center for urodynamic studies.
2. Perception of change in treatment over each of the 3 main signs of overactive bladder syndrome (frequency, nocturia, urinary incontinence), scored by the patient on a valid and reliable seven-point scale (markedly worse, moderately worse , Slightly worse, equal, slightly better, moderately better and markedly better). Change will be considered when the patient has moderately or markedly improved. Insufficient improvement in the rest of the answers.
3. Number of adverse effects related to the mouth per month and 3 months of follow-up. At each visit, a blind assessor will determine if there was any adverse effect during the previous month. The effects may be related to deterioration in dry mouth (or xerostomia), salivary flow and oral quality of life compared to basal. Xerostomia will be measured using a validated questionnaire (36) consisting of 7 items related to oral dryness and a last item where the patient scores overall their level of dryness, this questionnaire that allows us to measure the intensity of oral symptoms using Scales Analog Visuals (EVAs). The amount of saliva will be measured with the non-stimulated salivary flow test. This test allows to know changes in the secretion and if it performs a normal or low salivary secretion. Oral quality of life will be measured using the Oral Health Impact Profile (OHIP-14) test in its Spanish-validated version. It is presented in the form of questions about everyday situations that the patient must respond to as often as they happen.
4. Number of other adverse effects. It will measure the new onset of tingling in legs constipation, dyspepsia, vomiting, heartburn, dry eyes, and others. All of them will be measured from the patient's self-report. |
1. Cambios urodinámicos acontecidos a los 3 meses en relación a los siguientes parámetros: i)Volumen miccional al cual se origina la primera contracción no inhibida, en caso de hiperactividad detrusoriana; ii) Amplitud de las contracciones no inhibidas; iii) Capacidad vesical total iv) Residuo postmiccional; v) Flujometría: Qmax, Q medio, tiempo de micción. Todos estos parámetros serán medidos con instrumentos calibrados y disponibles en cada centro para la realización de estudios urodinámicos.
2. Percepción de cambio acontecido con el tratamiento sobre cada uno de los 3 signos principales del síndrome de vejiga hiperactiva (frecuencia, nocturia, incontinencia urinaria), puntuada por el paciente sobre una escala válida y fiable de siete puntos (marcadamente peor, moderadamente peor, ligeramente peor, igual, ligeramente mejor, moderadamente mejor y marcadamente mejor). Se considerará cambio cuando el paciente haya mejorado moderada o marcadamente. Insuficiente mejora en el resto de respuestas.
3. Número de efectos adversos relacionados con la boca al mes y 3 meses de seguimiento. En cada visita, un evaluador ciego determinará si existió algún efecto adverso durante el mes anterior. Los efectos podrán ser relativos a un deterioro en la sequedad de boca (o xerostomía), el flujo salival y la calidad de vida oral comparada con basal. La xerostomía se medirá mediante un cuestionario validado formado por 7 ítems relacionados con la sequedad oral y un último ítem donde el paciente puntúa de forma global su nivel de sequedad, este cuestionario que nos permite medir la intensidad de los síntomas orales mediante Escalas Visuales Analógicas (EVAs). La cantidad de saliva se medirá con el test de flujo salival no estimulado . Este test permite saber cambios en la secreción y si realiza una secreción salival normal o baja. La calidad de vida oral se medirá con el test Perfil de Impacto de Salud Oral (OHIP-14) en su versión validada al español . Se presenta en forma de preguntas sobre situaciones de su día a día, que el paciente debe responder según con la frecuencia en que le suceden.
4. Número de otros efectos adversos. Se medirá la nueva aparición de hormigueo en piernas estreñimiento, dispepsia, vómitos, pirosis, sequedad de ojos, y otros. Todos ellos serán medidos a partir del autoinforme del paciente. |
