ScienceDaily (2010-05-29) -- A 17-year-long community study looking at symptoms of enlarged prostate in over 2,000 men age 40 to 79 years suggests that surgery for benign prostatic hyperplasia offers more relief from incontinence and obstruction symptoms than treatment from drug-based therapy, according to a new study.
Overall, results show:結論：
* Urinary incontinence was a common condition, coexisting with BPH/lower urinary tract symptoms. (尿失禁是個普遍的現象，伴同前列腺肥大/低尿道炎症候群)
* In the community setting, patients with the highest symptom scores were most likely to receive surgical intervention.(在社群中，最高的發病症候者會有外科手術介入)
* Symptoms stabilized and did not get worse after treatment of all kinds. (徵狀在任何療法處理之後，會穩定下來且不再惡化)
* Patients who underwent transurethral resection of the prostate (TURP) had the greatest decrease in both symptoms and incontinence compared to other treatment groups. Pre-TURP the incontinence rate was 64.5 percent and post-TURP it was 41.9 percent.(病人經尿道前列腺切除術，比起其他的療法，其徵狀及漏尿情形，以TURP具最大的降幅。TURP手術前，漏尿率64.5%，之後只有41.9%)
Results showed that of the 2,184 men:
1,574 (72%) received no treatment for BPH symptoms.
307 (14%) took alpha adrenergic receptor blockers (α-ARs).
195 (9%) took the medication 5-alpha-reductase inhibitors (ARIs).
23 (1%) received surgical laser vaporization.
85 (4%) received surgical transurethral resection of the prostate (TURP).
