Abstract
Objective

To describe the types of penile prostheses and their components, to review the appropriate magnetic resonance imaging (MRI) acquisition protocol, and to describe the normal imaging findings and possible complications in patients with inflatable penile implants.

Conclusion

Three-piece inflatable penile prostheses are the last link in the treatment chain for erectile dysfunction. They can develop complications, which are classified as non-infectious related to the surgical technique, infectious, or due to mechanical failure of the device. MRI is the most appropriate imaging technique for the postsurgical evaluation of penile prostheses. Images are acquired in three planes using sequences with high spatial resolution, first with the prosthesis at rest and then with the prosthesis activated.

Resumen
Objetivo

Describir los tipos de prótesis de pene y sus componentes, revisar el protocolo de adquisición adecuado en resonancia magnética (RM), describir los hallazgos de imagen normales y las posibles complicaciones en pacientes con prótesis hidráulica de pene.

Conclusión

Las prótesis hidráulicas tricompartimentales de pene son el último eslabón en la cadena terapéutica de la disfunción eréctil. Pueden presentar complicaciones, que se clasifican en no infecciosas vinculadas a la técnica quirúrgica, infecciosas y por fallo mecánico del dispositivo. La RM es la técnica de imagen más adecuada en la evaluación postquirúrgica de las prótesis de pene. Se realiza con secuencias de alta resolución espacial con la prótesis en reposo y en los tres planos del espacio, y se repite la adquisición triplanar con la prótesis activada.
