Resumen
Introducción

La hiperplasia benigna de próstata (HBP) se acompaña de síntomas del tracto urinario inferior (STUI) que pueden causar alteraciones eyaculatorias, aunque éstas podrían ser además consecuencia del tratamiento con alfa-bloqueantes

Objetivos

Determinar la prevalencia de disfunción eyaculatoria en pacientes con HBP tratados con alfa-bloqueantes. Secundariamente, evaluar el efecto del tipo de fármaco y la relación de las alteraciones eyaculatorias con factores pronósticos y la gravedad de la HBP

Material y métodos

Estudio epidemiológico, transversal, no controlado y abierto en 1.177 pacientes ≥40 años diagnosticados de HBP/STUI con más de 6 meses de evolución, tratados con el mismo alfa-bloqueante durante como mínimo los últimos 3 meses. El grado de disfunción eyaculatoria se determinó mediante el dominio sobre eyaculación del Male Sexual Health Questionnaire (MSHQ). Los resultados se estratificaron según la edad y gravedad de la HBP, establecida mediante el International Prostate Symptoms Score (IPSS)

Resultados

Se ha estimado una prevalencia de disfunción eyaculatoria del 82,6% en pacientes con HBP/STUI en tratamiento con alfa-bloqueantes. Aunque generalmente leve, un amplio porcentaje de quienes la sufren la consideran un problema. La edad avanzada es el factor más influyente en la gravedad tanto de las alteraciones eyaculatorias como de los síntomas prostáticos. Entre ambos parámetros se ha establecido una sólida correlación. Finalmente, entre los alfa-bloqueantes evaluados, la alfuzosina se ha asociado a una mejor función sexual

Conclusiones

Más del 80% de pacientes con HBP sufren alteraciones eyaculatorias, estrechamente relacionadas con la severidad de los síntomas prostáticos y la edad del individuo. Al establecer tratamiento con alfa-bloqueantes, deberíamos tener en cuenta que la alfuzosina es el que menos impacto tiene sobre la función eyaculatoria

Abstract
Introduction

Benign prostatic hyperplasia (BPH) is characterized by lower urinary tract symptoms (LUTS) that may cause ejaculatory disorders, although they could be also a consequence of alpha-blocker treatment

Objectives

To determine the prevalence of ejaculatory dysfunction in patients with HBP undergoing alpha-blocker therapy. Secondary objectives were to evaluate the effect of different drugs on normal ejaculation and the relationship of dysfunction degree to prognostic factors and BPH severity

Materials and methods

Epidemiologic, transversal, uncontrolled and open-label study in 1.177 patients older than 40, who had been diagnosed of BPH/LUTS with more than 6 months of evolution and treated with the same alpha-blocker for at least the last 3 months. Severity of ejaculatory dysfunction was determined by the domain on ejaculation of the Male Sexual Health Questionnaire (MSHQ). Results were stratified by age and BPH severity, determined by the International Prostate Symptoms Score (IPSS)

Results

The prevalence of ejaculatory dysfunction has been estimated to be 82.6% in patients with BPH/LUTS treated with alpha-blockers. Although usually mild, the dysfunction is considered as bothersome by a high percentage of those who suffer it. Advanced age is the most influential factor in the severity of both ejaculatory abnormalities and prostate symptoms. Moreover, a solid correlation between these two parameters has been established. Finally, among the analyzed alpha-blockers, alfuzosin has been associated with the best sexual function

Conclussions

More than 80% of patients with BPH suffer ejaculatory abnormalities, which are closely related to the severity of prostate symptoms and increased age. When initiating alpha-blocker treatment, we should consider that alfuzosin is the one with less negative impact on ejaculatory function
