Community-based research on the benign prostatic hyperplasia prevalence rate in Korean rural area

Abstract

PurposeWe investigated the prevalence rate of benign prostatic hyperplasia (BPH) among Korean males in a rural area through a cross-sectional, community-based epidemiologic survey and analyzed the correlation with epidemiologic factors.Materials and MethodsA total of 779 males who lived in Yangpyeong County participated in a prostate examination campaign. Targeting these men, we collected the International Prostate Symptom Score (IPSS), medical history, demographic information, serum prostate-specific antigen, and prostate volume as measured by transrectal ultrasonography. The data for 599 participants were analyzed, excluding 180 men who had a possibility of prostate cancer. BPH was defined as an IPSS of 8 points or higher and a prostate volume of 25 mL or more.ResultsThe prevalence rate of BPH was 20.0%. The prevalence rate increased with age. There were 2 subjects (4.4%) in the age group of 40-49 years, 18 subjects (10.9%) in the age group of 50-59 years, 44 subjects (22%) in the age group of 60-69 years, and 56 subjects (26.6%) in the age group of over 70 years; this increase with age was statistically significant (p<0.001). In the BPH group, the average IPSS was 14.67±5.95, the average prostate volume was 37.04±11.71 g, and the average prostate-specific antigen value was 1.56±0.88 ng/mL. In the analysis of correlations between the epidemiologic factors and the risk of BPH, smoking was the only statistically significant factor.ConclusionsThe total prevalence rate of BPH in this study was 20.0%, which was a little lower than the rate reported in other cities or rural areas.

The global burden of lower urinary tract symptoms suggestive of benign prostatic hyperplasia: A systematic review and meta-analysis

“…For example, in the study by Trueman and colleagues 25 , the presence of BPH was assessed using a self-administered questionnaire. In contrast, a study by Goh and associates 40 in Korea reported a prevalence rate of 20%. Participants were surveyed by trained investigators and prostate disease was assessed by a physical examination and measurement of prostate volume and serum prostate specific antigen.…”

Efficacy of holmium laser enucleation of the prostate (HoLEP) in men with bladder outlet obstruction (BOO) and non‐neurogenic bladder dysfunction

“…All patients had transrectal ultrasonographic evidence of BPH with prostate volume of 25 ml or above that was consistent with BOO [9]. Patients were divided into three groups according to the results of urodynamic study (UDS) just before the surgery: one comprised patients with BOO-only and others comprised patients with BOO and detrusor dysfunction.…”

A study of prostatic fossa packing: a modified technique in Freyer’s prostatectomy for achieving hemostasis

“…In a Korean study, there were 2 patients (4.4%) in the 40-49 years group, 18 patients (10.9%) in 50-59 years group, 44 patients (22%) in the age group of 60-69 years group and 56 patients (26.6%) above the age of 70 years. 4 The prevalence of BPH was 21.0% overall: 11.6% among subjects aged 50 to 59 years, 18.1% for those aged 60 to 69, 30.8% for those aged 70 to 79 and 50.8% among those aged 80 years or more. Compared with previous studies in urban or rural areas, the prevalence was slightly lower.…”
