Study of quality of life in patients with benign prostatic hyperplasia under treatment with silodosin

Abstract

Objectives: To assess the impact of urinary symptoms associated with benign prostatic hyperplasia and its treatment with silodosin, on quality of life (QoL) and sexual function, depending on age, severity of symptoms, time on treatment and prostate size.

Material and methods: A cross-sectional, observational study was conducted in 305 urology practices all around Spain. Socio-demographic and clinical data were collected and patients filled the following questionnaires: EQ-5D, Sexual Function Index (SFI) and International Prostate Symptom Score (IPSS). Multiple regression models were used to determine factors independently associated with patients' QoL.

Results: A total of 1,019 patients were enrolled, mean (SD) for: age 62.7 (5.7), EQ-5D 89.9 (13.9), sexual drive-SFI 3.71 (1.67), erection-SFI 6.11 (3.08), ejaculation-SFI 4.50 (2.06) problems-SFI 6.85 (3.37) and overall satisfaction-SFI 2.00 (0.99). The EQ-5D and SFI score were statistically lower with: older age, severe LUTS and greater prostate size (P<.01), but no differences were found related to time on treatment with silodosin. The EQ-5D score was positively associated with sexual satisfaction and desire size of SFI and the EQ-5D VAS score, and negatively with disability, semi-urban residence and comorbidities in the multiple regression analyses.

Conclusions: Severe LUTS and older age are associated to a greater deterioration in sexual function and quality of life. However time on treatment with silodosin does not produce deterioration in the quality of life.
