Ja. Chicharromolero et al., PREVALENCE OF BENIGN PROSTATIC HYPERPLASIA IN SPANISH MEN 40 YEARS OLD OR OLDER, The Journal of urology, 159(3), 1998, pp. 878-882
Purpose: We estimate the prevalence of benign prostatic hyperplasia (B
PH) according to symptoms as well as prostate obstruction determined b
y uroflowmetry and prostate size. Materials and Methods: A cross-secti
onal study was performed at the autonomous community of Andalusia in 1
,106 men 40 years old or older. The International Prostate Symptom Sco
re (I-PSS) questionnaire was used to establish symptoms, abdominal and
transrectal ultrasonography was done to measure prostate size and uro
flowmetry was performed to measure urinary flow obstruction. Results:
The prevalence of moderate or severe symptoms was 24.94% and it increa
sed with age. Of the 1,106 subjects 4.19% had severe prostatism, while
12.45% had poor quality of life (I-PSS greater than 3). Average prost
ate size was greater than 30 gm, in men 60 years old or older. Maximum
urine flow was less than 10 and 15 ml. per second in 25.97 and 55.67%
of the men, respectively. The prevalence of BPH, defined as I-PSS gre
ater than 7, maximum flow less than 15 ml. per second and prostate siz
e greater than 30 gm., was 11.77% (range 0.75 to 30 at ages 40 to 49 a
nd greater than 70 years, respectively). Conclusions: The prevalence o
f BPH increases with age. Moderate prostatism is perceived as resultin
g in poor quality of life by young subjects and good quality of life b
y some older subjects. In some men there were symptoms and obstruction
but no prostate enlargement. This percentage persists with age after
50 years, when the prevalence of BPH starts to increase.
