Pp. Sagnier et al., RESULTS OF AN EPIDEMIOLOGIC SURVEY USING A MODIFIED AMERICAN-UROLOGICAL-ASSOCIATION SYMPTOM INDEX FOR BENIGN PROSTATIC HYPERPLASIA IN FRANCE, The Journal of urology, 151(5), 1994, pp. 1266-1270
The prevalence of urinary symptoms associated with benign prostatic hy
perplasia was studied in a community-based, nationwide, representative
sample of 2,011 French men 50 to 80 years old. Symptoms were assessed
by the American Urological Association symptom index. After exclusion
of patients with prostate cancer, 6.9% of the subjects reported havin
g undergone prostate surgery. Among the surgery-free subjects, nocturi
a and repeat voiding within 2 hours were the most prevalent symptoms.
Based on the American Urological Association symptom index, 18.8% of t
he men were considered free of urinary symptoms, and 67%, 13% and 1.2%
, respectively, ranked between 1 sind 7, 8 and 19, and 20 or more. The
proportion of men scoring greater than 7 approximately doubled with e
ach decade of age. Our estimation indicated that in 1992 approximately
1.14 million French men had moderate to severe urinary symptoms that
were likely to be associated with benign prostatic hyperplasia. Previo
us studies had yielded higher prevalence estimates, probably due to di
fferences in sampling design and diagnostic criteria.
