A cistometria \u00e9 um componente-chave do teste urodin\u00e2mico abrangente usado para avaliar pacientes com sintomas do trato urin\u00e1rio inferior (STUI).1<\/sup> \u00c9 particularmente valiosa no diagn\u00f3stico e caracteriza\u00e7\u00e3o de condi\u00e7\u00f5es como disfun\u00e7\u00e3o neurog\u00eanica da bexiga, hiperatividade do detrusor, incontin\u00eancia urin\u00e1ria de esfor\u00e7o e obstru\u00e7\u00e3o da sa\u00edda da bexiga.2<\/sup><\/p>\n \n

O procedimento \u00e9 indicado para pacientes com sintomas urin\u00e1rios complexos ou refrat\u00e1rios, incluindo aqueles com condi\u00e7\u00f5es neurol\u00f3gicas que afetam a fun\u00e7\u00e3o da bexiga (esclerose m\u00faltipla, les\u00e3o medular, diabetes com neuropatia), incontin\u00eancia urin\u00e1ria persistente apesar do tratamento conservador, infec\u00e7\u00f5es recorrentes do trato urin\u00e1rio e dificuldades inexplic\u00e1veis de mic\u00e7\u00e3o.1<\/sup> 3<\/sup><\/p>\n \n

Durante o procedimento, o paciente \u00e9 posicionado confortavelmente e um cateter \u00e9 inserido por via transuretral na bexiga. Um segundo cateter ou sonda de press\u00e3o pode ser colocado no reto ou na vagina para medir a press\u00e3o abdominal.2<\/sup> A bexiga \u00e9 gradualmente preenchida com fluido est\u00e9ril a uma taxa controlada enquanto as medi\u00e7\u00f5es de press\u00e3o s\u00e3o registradas. O paciente relata sensa\u00e7\u00f5es experimentadas durante o enchimento (primeira vontade de urinar, forte desejo, urg\u00eancia), e estas est\u00e3o correlacionadas com os volumes e press\u00f5es vesicais correspondentes.1<\/sup> 2<\/sup><\/p>\n \n

A cistometria ajuda a diferenciar entre v\u00e1rias causas de disfun\u00e7\u00e3o da bexiga, como distinguir entre m\u00e1 contratilidade do detrusor e obstru\u00e7\u00e3o da sa\u00edda da bexiga em pacientes com fluxo urin\u00e1rio fraco.3<\/sup> Os resultados orientam as decis\u00f5es de tratamento, incluindo sele\u00e7\u00e3o de medicamentos, recomenda\u00e7\u00f5es de terapia do assoalho p\u00e9lvico ou interven\u00e7\u00f5es cir\u00fargicas quando apropriado.1<\/sup><\/p>\n

A EAU recomenda cistometria antes de tratamentos invasivos para incontin\u00eancia e bexiga neurog\u00eanica. Par\u00e2metros cr\u00edticos incluem: capacidade cistom\u00e9trica m\u00e1xima (normal 300-500 mL), complac\u00eancia (> 20 mL\/cmH\u2082O), press\u00e3o m\u00e1xima do detrusor durante enchimento e presen\u00e7a de hiperatividade detrusora. Em bexiga neurog\u00eanica, press\u00f5es detrusoras > 40 cmH\u2082O durante o enchimento indicam risco para o trato urin\u00e1rio superior.<\/p>","gt-related-evidence":null,"gt-featured":true,"gt-ai-referenced":false,"gt-view-count":114},"yoast_head":"\nCistometria: Estudo Urodin\u00e2mico da Bexiga | Rigicon<\/title>\n<meta name=\"description\" content=\"Conhe\u00e7a a cistometria, exame urodin\u00e2mico que avalia as fases de enchimento e esvaziamento da bexiga.
