Em uma s\u00e9rie de um \u00fanico centro com 49 pacientes que receberam cilindros de expans\u00e3o controlada de di\u00e2metro reduzido, as causas subjacentes da fibrose peniana grave foram explante pr\u00e9vio por infec\u00e7\u00e3o (67,3%), priapismo isqu\u00eamico (16,3%) e fibrose idiop\u00e1tica (16,3%)<sup>1<\/sup>.<\/p>\n    \n    <p>Os crit\u00e9rios de sele\u00e7\u00e3o de pacientes concentram-se em indiv\u00edduos com disfun\u00e7\u00e3o er\u00e9til que n\u00e3o obtiveram sucesso com tratamentos conservadores e apresentam fibrose dos corpos cavernosos que tornaria o implante de uma pr\u00f3tese padr\u00e3o dif\u00edcil ou imposs\u00edvel<sup>3<\/sup>. A avalia\u00e7\u00e3o pr\u00e9-operat\u00f3ria frequentemente inclui ultrassonografia peniana para avaliar o grau de fibrose, o que ajuda a estabelecer expectativas realistas do paciente quanto aos resultados p\u00f3s-operat\u00f3rios<sup>3<\/sup>.<\/p>\n    \n    <p>O procedimento cir\u00fargico de implante normalmente envolve uma abordagem escrotal transversa, com dilata\u00e7\u00e3o cuidadosa dos corpos cavernosos fibr\u00f3ticos<sup>4<\/sup>. Devido ao design de cilindro mais estreito, o dispositivo pode ser implantado com sucesso mesmo em casos de fibrose grave nos quais os cilindros padr\u00e3o n\u00e3o caberiam<sup>4<\/sup>.
