Age-stratified analysis of I-PSS and QoL values in spanish patients with symptoms potentially related to BPH.
OBJECTIVE
The main goal of the present study was to determine age-related symptom changes using a validated Spanish International Prostate Symptom Score (I-PSS) and quality of life index (QoL) in Spanish patients with symptomatic benign prostatic hyperplasia (BPH).


METHODS
A total of 2,875 patients with the clinical diagnosis of symptomatic BPH were evaluated. Data were collected during current medical practice in a national study. Patients were excluded if they had any previous prostate operation or suspicion of prostate cancer. I-PSS was self-administered and compared with the physician's global impression.


RESULTS
I-PSS symptoms, both voiding and storage symptoms, increased significantly with age (p<0.0001) as well as QoL (p<0.0017). A change in the I-PSS categories (minor, moderate and severe) was found with age, increasing severe symptomatic patients in the oldest groups. A significant correlation was found between I-PSS and QoL (r = 0.49, p<0.001), being this relationship linear and not significantly influenced by age.


CONCLUSIONS
This study confirms reliable results using a validated Spanish I-PSS in a large national representative sample of Spanish patients with BPH symptoms. The age-stratified analysis showed that the natural progression of BPH with age was related to an increased symptomatology and bothersomeness, well reflected by increases in the I-PSS and QoL values. Nevertheless, the effect of symptomatology on quality of life was not strongly influenced by the age of the patient.
