Overview
Plain-Language Overview
Benign Prostatic Hyperplasia (BPH) is a common condition affecting the prostate gland, which is part of the male reproductive system. It involves the noncancerous enlargement of the prostate, usually occurring as men age. This enlargement can press on the urethra, the tube that carries urine out of the body, causing problems with urination. Common symptoms include a weak urine stream, difficulty starting urination, and frequent urination, especially at night. Although BPH is not cancerous, it can significantly impact quality of life by interfering with normal bladder function.
Clinical Definition
Benign Prostatic Hyperplasia (BPH) is a nonmalignant proliferation of both stromal and glandular elements of the prostate, primarily affecting the transition zone around the urethra. It is driven by androgenic stimulation, particularly dihydrotestosterone (DHT), which promotes cellular hyperplasia. The condition leads to bladder outlet obstruction and lower urinary tract symptoms (LUTS) such as hesitancy, weak stream, and nocturia. Histologically, BPH is characterized by increased numbers of epithelial and smooth muscle cells. It is a highly prevalent disorder in aging men and is a major cause of urinary symptoms requiring medical evaluation.
