En las aplicaciones urol\u00f3gicas, los expansores tisulares suelen ser pr\u00f3tesis de pene inflables (PPI) que cumplen una doble funci\u00f3n: proporcionar cierto grado de funci\u00f3n er\u00e9ctil y, al mismo tiempo, expandir con el tiempo el tejido cavernoso cicatricial o fibr\u00f3tico<sup>1<\/sup>. Estos dispositivos act\u00faan aplicando una presi\u00f3n radial constante sobre la t\u00fanica albug\u00ednea y los espacios cavernosos. Se cree que esta presi\u00f3n induce v\u00edas de mecanotransducci\u00f3n que estimulan la adaptaci\u00f3n celular y la remodelaci\u00f3n tisular, lo que permite de forma eficaz una expansi\u00f3n gradual del tejido<sup>2<\/sup>. En varones con fibrosis de los cuerpos cavernosos, se ha descrito que la insuflaci\u00f3n prolongada durante 8-12 meses expande la cavidad del cilindro, lo que puede permitir la implantaci\u00f3n posterior de cilindros prot\u00e9sicos de mayor tama\u00f1o o una mejor acomodaci\u00f3n cavernosa para un implante actual o futuro<sup>3<\/sup>.","gt-synonyms":"Pr\u00f3tesis de pene inflable (cuando se utiliza como expansor tisular), expansor tisular IPP, expansor tisular cavernoso, expansor prot\u00e9sico peneano, expansor prot\u00e9sico de tama\u00f1o reducido (downsized), distensor tisular mec\u00e1nico","gt-citation":"[1] Chung, P.

Los criterios de selecci\u00f3n de pacientes incluyen un aporte vascular adecuado al pene, la ausencia de infecci\u00f3n activa y unas expectativas realistas del paciente respecto al proceso de expansi\u00f3n, los plazos y los posibles resultados. El procedimiento quir\u00fargico suele consistir en la implantaci\u00f3n inicial de cilindros de PPI de tama\u00f1o adecuado, a menudo de tama\u00f1o reducido. A continuaci\u00f3n, se sigue un protocolo de insuflaci\u00f3n estructurado, que puede incluir el ciclado diario o regular del dispositivo durante un periodo de 8-12 meses o m\u00e1s, seg\u00fan los objetivos cl\u00ednicos y la respuesta del paciente<sup>1<\/sup>. Los estudios cl\u00ednicos han demostrado que este enfoque puede dar lugar a aumentos significativos de la longitud implantable del cilindro (p. ej., 0,9-1,2 cm tras &ge;2 a\u00f1os de expansi\u00f3n en algunas cohortes), y un porcentaje considerable de pacientes logra ganancias medibles (p. ej., el 60% logra aumentos de &gt;0,5 cm y el 40% logra aumentos de &ge;1 cm)<sup>1<\/sup>. En una serie de 37 varones con fibrosis de los cuerpos cavernosos, el cambio posterior a cilindros de tama\u00f1o est\u00e1ndar fue posible en todos los pacientes tras 8-12 meses de insuflaci\u00f3n
