O Cuff Transcorp\u00f3reo \u00e9 uma t\u00e9cnica especializada de posicionamento do cuff do esf\u00edncter urin\u00e1rio artificial (AUS), na qual o cuff \u00e9 posicionado atrav\u00e9s dos corpos cavernosos para casos de revis\u00e3o de incontin\u00eancia urin\u00e1ria.1<\/sup> Essa abordagem cir\u00fargica envolve a cria\u00e7\u00e3o de um t\u00fanel atrav\u00e9s de uma por\u00e7\u00e3o dos corpos cavernosos para permitir a compress\u00e3o circunferencial da uretra, evitando a dissec\u00e7\u00e3o uretral posterior direta.2<\/sup> A t\u00e9cnica foi descrita pela primeira vez em 2002 como um procedimento de resgate para pacientes com uretra comprometida, especialmente aqueles com hist\u00f3rico de eros\u00e3o uretral pr\u00e9via, radioterapia ou uretroplastia.3<\/sup><\/p>\n

O Cuff Transcorp\u00f3reo \u00e9 utilizado principalmente em cen\u00e1rios cl\u00ednicos espec\u00edficos que envolvem a incontin\u00eancia urin\u00e1ria de esfor\u00e7o (SUI) masculina, nos quais o implante padr\u00e3o do esf\u00edncter urin\u00e1rio artificial (AUS) \u00e9 desafiador ou contraindicado.1<\/sup> Esses cen\u00e1rios incluem:<\/p>\n

1. Cirurgias de revis\u00e3o<\/h3>\n

Em pacientes que apresentaram eros\u00e3o pr\u00e9via do cuff do AUS ou falha mec\u00e2nica com necessidade de remo\u00e7\u00e3o e substitui\u00e7\u00e3o do dispositivo.2<\/sup> A abordagem transcorp\u00f3rea fornece volume tecidual adicional entre o cuff e a uretra, reduzindo potencialmente o risco de eros\u00e3o recorrente.3<\/sup><\/p>\n

2. Uretra comprometida<\/h3>\n

Em pacientes com atrofia uretral, uretroplastia pr\u00e9via ou dano tecidual induzido por radia\u00e7\u00e3o, nos quais a dissec\u00e7\u00e3o padr\u00e3o da uretra bulbar pode ser dif\u00edcil ou perigosa.4<\/sup> A t\u00e9cnica \u00e9 particularmente valiosa em pacientes submetidos \u00e0 radioterapia p\u00e9lvica, que pode causar fibrose tecidual e vasculariza\u00e7\u00e3o deficiente.5<\/sup><\/p>\n

3. Procedimentos de resgate<\/h3>\n

Como op\u00e7\u00e3o de resgate quando outros tratamentos para incontin\u00eancia falharam, especialmente em pacientes de alto risco com m\u00faltiplas cirurgias pr\u00e9vias ou radioterapia.6<\/sup><\/p>\n

O procedimento \u00e9 realizado sob anestesia geral por meio de uma abordagem perineal. Ap\u00f3s a exposi\u00e7\u00e3o da uretra bulbar, corporotomias bilaterais s\u00e3o criadas e o cuff \u00e9 posicionado atrav\u00e9s dos corpos cavernosos, englobando tanto a uretra quanto uma por\u00e7\u00e3o da t\u00fanica albug\u00ednea.1<\/sup> Essa t\u00e9cnica evita a necessidade de mobiliza\u00e7\u00e3o circunferencial da uretra, o que poderia comprometer o suprimento sangu\u00edneo uretral em um tecido j\u00e1 vulner\u00e1vel.4<\/sup><\/p>\n

Dados de desfechos mostram que a abordagem transcorp\u00f3rea oferece taxas de contin\u00eancia satisfat\u00f3rias (69-88% alcan\u00e7ando contin\u00eancia social) nesses casos desafiadores.2<\/sup> No entanto, estudos que comparam cuffs transcorp\u00f3reos com cuffs padr\u00e3o ou de 3,5 cm demonstraram taxas de eros\u00e3o potencialmente mais elevadas com a t\u00e9cnica transcorp\u00f3rea no acompanhamento em longo prazo.5<\/sup> O procedimento tamb\u00e9m pode impactar a fun\u00e7\u00e3o er\u00e9til em pacientes potentes, pois envolve dissec\u00e7\u00e3o atrav\u00e9s dos corpos cavernosos.6<\/sup> Portanto, a sele\u00e7\u00e3o adequada dos pacientes e o aconselhamento sobre poss\u00edveis complica\u00e7\u00f5es e expectativas s\u00e3o componentes essenciais na tomada de decis\u00e3o cl\u00ednica.<\/p>","gt-related-evidence":null,"gt-featured":false,"gt-ai-referenced":true,"gt-view-count":0},"yoast_head":"\nCuff Transcorp\u00f3reo: T\u00e9cnica Cir\u00fargica de
