Se considera que una mujer es fértil después de la menarquia y hasta convertirse en posmenopáusica, a menos que se haya sometido a un procedimiento de esterilización permanente (histerectomía, salpingectomía, ooforectomía bilateral). Un estado posmenopáusico se define como ausencia de menstruación durante 12 meses sin una causa medica alternativa Criterios de diálisis adecuada de acuerdo a las guías KDOQI: Objetivo de spKt/V >1,4 por sesión de hemodiálisis para los pacientes tratados tres veces por semana Enfermedad renal estable en los últimos 3 meses. Se considera que la enfermedad renal crónica está estable cuando cumple los siguientes criterios: oLas patologías crónicas asociadas están controladas adecuadamente y no hayan requerido hospitalización en los últimos 3 meses. oEl paciente no presenta alteraciones hemodinámicas (TA ≥ 90/60 y ≤ 160/90 mm Hg) fuera de la sesión de hemodiálisis. oNo hay signos de infección aguda valorable por la ausencia de leucocitosis en el hemograma oNo existe evidencia clínica de patología tumoral a criterio del investigador |
