LUTS (lower urinary tract symptoms) are symptoms related to problems of the lower urinary tract (bladder, prostate and urethra).
LUTS are broadly grouped into voiding (obstructive) or storage (irritative) symptomsa).
– The common cause of obstructive symptoms is an enlarged prostate or BPH (benign prostatic hyperplasia).
– The common cause of the storage symptoms is overactive bladder.
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate. As the prostate gets bigger, it may squeeze or partly block the urethra, causing problems while urinating.
BPH is common in aging men, and about half of all men between the age of 51 and 60 suffer from BPH. It has been observed that up to 90% of men over the age 80 years suffer from BPH.
LUTS/BPH Worldwide and in the US
Worldwide, an estimated 1.1 billion men, will be affected by at least one of the low urinary tract symptoms by 2018b) , which includes 645 million aging men (40 years and older). Worldwide prevalence of LUTS/BPH will affect ~45% of men.
By 2018 estimated 40 million men of 40 years and older are expected to have urological disorders (LUTS/BPH) in the US.
Occurrence of LUTS/BPH will rise with the increase of the life expectancy.
