Resumen Objetivo Describir los tipos de protesis de pene y sus componentes, revisar el protocolo de adquisicion adecuado en resonancia magnetica (RM), describir los hallazgos de imagen normales y las posibles complicaciones en pacientes con protesis hidraulica de pene. Conclusion Las protesis hidraulicas tricompartimentales de pene son el ultimo eslabon en la cadena terapeutica de la disfuncion erectil. Pueden presentar complicaciones, que se clasifican en no infecciosas vinculadas a la tecnica quirurgica, infecciosas y por fallo mecanico del dispositivo. La RM es la tecnica de imagen mas adecuada en la evaluacion postquirurgica de las protesis de pene. Se realiza con secuencias de alta resolucion espacial con la protesis en reposo y en los tres planos del espacio, y se repite la adquisicion triplanar con la protesis activada.

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 Estimar el riesgo de muerte cancer especifica (MCE) frente al riesgo competitivo de mortalidad por otras causas (MOC) en pacientes con cancer de prostata localizado (CaP-Lo) tratados mediante prostatectomia radical (PR). Material y metodo Estudio observacional de una cohorte de 982 pacientes con CaP-Lo tratados mediante PR seleccionados de la base de datos del registro de CaP de nuestro servicio. Se ha realizado un analisis de riesgos competitivos calculando la probabilidad de MCE en presencia del riesgo competitivo por MOC. Se han construido curvas de incidencia acumulada y se han llevado a cabo estimaciones puntuales a 5, 10 y 15 anos. El analisis se ha estratificado por edad (≤ 65 vs. > 65 anos) y por grupos de riesgo: bajo (Gleason ≤ 6 y pT2abc); intermedio (Gleason = 7 y pT2abc) y elevado (Gleason 8-10 o pT3ab). Resultados Con una mediana de seguimiento de 60 meses, la probabilidad global de fallecer por CaP fue del 3,5% y la de fallecer por otras causas del 9%. Se evidencio un efecto competitivo por MOC. El riesgo de MOC fue de casi 3 veces superior al de MCE. Este efecto se mantuvo para todos los grupos de riesgo, si bien su magnitud disminuyo progresivamente conforme aumento el nivel del grupo de riesgo. A 10 anos, la MCE fue unicamente de 0, 1 y 2% para los grupos de riesgo bajo, intermedio y elevado respectivamente, mientras que la probabilidad MOC fue de 4, 4 y 10%. El riesgo de fallecer se evidencio a partir de 10 anos de seguimiento y fue mas frecuente por otras causas no atribuibles al CaP y en pacientes de edad > 65 anos. Conclusiones El beneficio de la PR puede estar sobreestimado, ya que el riesgo de MOC es superior al de MCE independientemente del grupo de edad y grupo de riesgo, sobre todo a partir de los 10 anos de seguimiento. Lo unico que varia es la magnitud de la razon MCE/MOC. Esta informacion puede ayudar a decidir el tratamiento activo en pacientes con CaP-Lo y corta expectativa de vida.

Objective: To determine the risk of cancer-specific mortality (CSM) versus the competing risk of mortality by other causes (MOC) in patients with localised prostate cancer (LPC) treated with radical prostatectomy (RP). Material and method: An observational cohort study of 982 patients with LPC treated with RP selected from our department's PC registry database. A competing risk analysis was performed, calculating the probability of CSM in the presence of the competing risk of MOC. Cumulative incidence curves were constructed, and point estimates were performed at 5, 10 and 15 years. The analysis was stratified by age ( 65 years) and risk group: low (Gleason score

To determine the risk of cancer-specific mortality (CSM) versus the competing risk of mortality by other causes (MOC) in patients with localised prostate cancer (LPC) treated with radical prostatectomy (RP).An observational cohort study of 982 patients with LPC treated with RP selected from our department's PC registry database. A competing risk analysis was performed, calculating the probability of CSM in the presence of the competing risk of MOC. Cumulative incidence curves were constructed, and point estimates were performed at 5, 10 and 15 years. The analysis was stratified by age (≤65 vs.65 years) and risk group: low (Gleason score ≤6 and pT2abc); intermediate (Gleason score of 7 and pT2abc) and high (Gleason score of 8-10 or pT3ab).With a median follow-up of 60 months, the overall probability of dying from PC was 3.5%, and the probability of dying from other causes was 9%. A competing effect for MOC was observed. The risk of MOC was almost 3 times greater than that of CSM. This effect remained for all risk groups, although its magnitude decreased progressively according to the risk group level. At 10 years, CSM was only 0%, 1% and 2% for the low, intermediate and high-risk groups, respectively, while the likelihood of MOC was 4%, 4% and 10%, respectively. The mortality risk was shown after 10years of follow-up and was higher for other causes not attributable to PC and for patients older than 65years.The benefit of RP might be overestimated, given that the risk of MOC is greater than that of CSM, regardless of the age group and risk group, especially after 10years of follow-up. The only parameter that varied was the magnitude of the CSM/MOC ratio. This information could help in choosing the active treatment for patients with LPC and short life expectancies.
