Os espasmos da bexiga ocorrem em v\u00e1rios cen\u00e1rios cl\u00ednicos e podem afetar indiv\u00edduos de todas as idades, embora se tornem mais comuns com o avan\u00e7o da idade.1<\/sup> Eles s\u00e3o frequentemente associados a diversas condi\u00e7\u00f5es, incluindo infec\u00e7\u00f5es do trato urin\u00e1rio (ITU), que causam inflama\u00e7\u00e3o e irrita\u00e7\u00e3o do revestimento da bexiga, desencadeando espasmos.2<\/sup> A s\u00edndrome da bexiga hiperativa (BH) \u00e9 caracterizada por espasmos frequentes da bexiga, urg\u00eancia e, \u00e0s vezes, incontin\u00eancia sem uma causa identific\u00e1vel.3<\/sup><\/p>\n \n

Espasmos da bexiga tamb\u00e9m s\u00e3o comuns ap\u00f3s cirurgias urol\u00f3gicas, particularmente prostatectomia, cistoscopia ou cirurgia da bexiga, onde o cateterismo \u00e9 necess\u00e1rio.4<\/sup> A presen\u00e7a de cateteres urin\u00e1rios permanentes \u00e9 um gatilho significativo para espasmos da bexiga, pois o corpo estranho estimula a contra\u00e7\u00e3o da bexiga na tentativa de expuls\u00e1-la.5<\/sup><\/p>\n \n

Condi\u00e7\u00f5es neurol\u00f3gicas que afetam as vias de controle da bexiga, como esclerose m\u00faltipla, doen\u00e7a de Parkinson, acidente vascular cerebral ou les\u00f5es na medula espinhal, podem levar \u00e0 disfun\u00e7\u00e3o neurog\u00eanica da bexiga com espasmos associados.6<\/sup> Cistite intersticial\/s\u00edndrome da dor na bexiga (CI\/BPS) apresenta-se com dor cr\u00f4nica na bexiga e espasmos, muitas vezes sem infec\u00e7\u00e3o ou patologia identific\u00e1vel.7<\/sup><\/p>\n \n

Outros fatores contribuintes incluem pedras na bexiga, c\u00e2ncer de bexiga, aumento da pr\u00f3stata em homens, constipa\u00e7\u00e3o, certos medicamentos (especialmente diur\u00e9ticos), consumo excessivo de cafe\u00edna ou \u00e1lcool e diabetes.8<\/sup> Em crian\u00e7as, espasmos na bexiga podem estar associados \u00e0 enurese noturna (enurese noturna) ou padr\u00f5es miccionais disfuncionais.9<\/sup><\/p>\n \n

As abordagens de tratamento variam de acordo com a causa subjacente e podem incluir medicamentos anticolin\u00e9rgicos, agonistas beta-3 adren\u00e9rgicos, relaxantes musculares, inje\u00e7\u00f5es de toxina botul\u00ednica, terapias de neuromodula\u00e7\u00e3o e modifica\u00e7\u00f5es comportamentais.10<\/sup> Para espasmos relacionados ao cateter, alterar o tipo ou tamanho do cateter pode proporcionar al\u00edvio, conforme demonstrado em estudos cl\u00ednicos comparando diferentes tipos de cateter.4<\/sup><\/p>\n

O tratamento depende da causa subjacente: antibi\u00f3ticos para infec\u00e7\u00e3o, anticolin\u00e9rgicos (oxibutinina, solifenacina) ou beta-3 agonistas (mirabegrona) para hiperatividade do detrusor, e otimiza\u00e7\u00e3o do manejo do cateter quando presente. Em espasmos p\u00f3s-operat\u00f3rios, belladona e suposit\u00f3rios de opi\u00e1ceos podem proporcionar al\u00edvio. A EAU recomenda avalia\u00e7\u00e3o completa para identificar e tratar a causa prim\u00e1ria antes da terapia sintom\u00e1tica.<\/p>","gt-related-evidence":null,"gt-featured":true,"gt-ai-referenced":false,"gt-view-count":80},"yoast_head":"\nEspasmos Vesicais: Contra\u00e7\u00f5es Involunt\u00e1rias da Bexiga | Rigicon<\/title>\n<meta name=\"description\" content=\"Saiba sobre espasmos vesicais, contra\u00e7\u00f5es involunt\u00e1rias da bexiga causando urg\u00eancia e dor.
