En una serie de un solo centro con 49 pacientes que recibieron cilindros de expansi\u00f3n controlada de di\u00e1metro reducido, las causas subyacentes de la fibrosis peniana grave fueron la explantaci\u00f3n previa por infecci\u00f3n (67,3%), el priapismo isqu\u00e9mico (16,3%) y la fibrosis idiop\u00e1tica (16,3%)<sup>1<\/sup>.<\/p>\n    \n    <p>Los criterios de selecci\u00f3n de pacientes se centran en personas con disfunci\u00f3n er\u00e9ctil en las que han fracasado los tratamientos conservadores y que presentan una fibrosis de los cuerpos cavernosos que dificultar\u00eda o imposibilitar\u00eda la implantaci\u00f3n de una pr\u00f3tesis est\u00e1ndar<sup>3<\/sup>. La evaluaci\u00f3n preoperatoria suele incluir una ecograf\u00eda peniana para valorar el grado de fibrosis, lo que ayuda a establecer expectativas realistas en el paciente respecto a los resultados posoperatorios<sup>3<\/sup>.<\/p>\n    \n    <p>El procedimiento de implantaci\u00f3n quir\u00fargica suele realizarse mediante un abordaje escrotal transversal, con una dilataci\u00f3n cuidadosa de los cuerpos cavernosos fibr\u00f3ticos<sup>4<\/sup>. Gracias al dise\u00f1o de cilindro m\u00e1s estrecho, el dispositivo puede implantarse con \u00e9xito incluso en casos de fibrosis grave en los que los cilindros est\u00e1ndar no cabr\u00edan<sup>4<\/sup>. Pueden emplearse t\u00e9cnicas e instrumentos quir\u00fargicos especializados, como los cavernotomos, para crear un espacio adecuado dentro de los cuerpos cavernosos fibr\u00f3ticos<sup>3<\/sup>.<\/p>\n    \n    <p>Los resultados esperados incluyen la satisfacci\u00f3n con la rigidez referida por aproximadamente el 73,5% de los pacientes<sup>1<\/sup>. No obstante, debe informarse a los pacientes sobre las posibles limitaciones, ya que m\u00e1s de la mitad pueden referir cierta insatisfacci\u00f3n debido a la p\u00e9rdida percibida de longitud y grosor del pene tras la implantaci\u00f3n<sup>2<\/sup>. Las complicaciones posoperatorias se producen en aproximadamente el 16,3% de los casos y pueden incluir infecciones (6,1%), herniaciones del cilindro (4,1%), fallos mec\u00e1nicos (4,1%) y, en raras ocasiones, necrosis del glande (2,0%)<sup>1<\/sup>. El dispositivo muestra resultados quir\u00fargicos aceptables, con una aceptabilidad moderada por parte de los pacientes en el seguimiento a largo plazo<sup>1<\/sup>.<\/p>","gt-related-evidence":null,"gt-featured":true,"gt-ai-referenced":false,"gt-view-count":86},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.7 (Yoast SEO v28.7) -
