Question 1

What is the Meaning of BPH?

Accepted Answer

Benign Prostatic Hyperplasia (BPH) represents a non-cancerous enlargement of the prostate gland, a common occurrence in aging men. It constitutes a histological diagnosis that may or may not manifest with clinical symptoms affecting urinary function.

Question 2

What is the Context of BPH?

Accepted Answer

The prostate gland, an accessory male reproductive organ, encircles the urethra at the base of the bladder. BPH originates primarily within the transitional zone of the prostate, influenced significantly by hormonal shifts, particularly the conversion of testosterone to dihydrotestosterone (DHT). This condition is recognized as a physiological aspect of the male aging process.

Question 3

What is the Significance of BPH?

Accepted Answer

BPH carries substantial clinical importance due to its propensity to cause lower urinary tract symptoms (LUTS), including increased urinary frequency, urgency, a weakened stream, nocturia, and a sensation of incomplete bladder emptying. These symptoms can considerably impair a patient's quality of life and, if severe, may lead to complications such as recurrent urinary tract infections, bladder calculi, or compromised renal function, often necessitating medical intervention.

Question 4

What is the Mechanism of BPH?

Accepted Answer

The underlying mechanism involves the abnormal proliferation of both stromal and epithelial cells within the prostate, primarily driven by sustained androgenic stimulation, specifically from dihydrotestosterone (DHT). DHT binds to intracellular androgen receptors in prostate cells, promoting the synthesis of growth factors and inhibiting programmed cell death, which collectively results in glandular hypertrophy and increased smooth muscle tone within the prostatic urethra, thereby impeding urine outflow.

Question 5

What is the Application of BPH?

Accepted Answer

Clinical management of BPH typically progresses from watchful waiting and lifestyle modifications to pharmacotherapy utilizing alpha-blockers to relax smooth muscle or 5-alpha-reductase inhibitors to reduce prostate volume. For individuals with persistent or severe symptoms refractory to medical treatment, surgical options like transurethral resection of the prostate (TURP) are considered. Treatment strategies are individualized based on symptom severity, prostate size, and patient preferences.

Question 6

What is the Metric of BPH?

Accepted Answer

Assessment of BPH involves a comprehensive clinical evaluation, including the administration of the International Prostate Symptom Score (IPSS) questionnaire to quantify symptom severity. A digital rectal examination (DRE) is performed to estimate prostate size and consistency, alongside measurement of serum Prostate-Specific Antigen (PSA) levels, primarily for prostate cancer screening. Uroflowmetry and post-void residual volume measurements objectively evaluate the degree of urinary flow obstruction.

Question 7

What is the Risk of BPH?

Accepted Answer

Potential risks associated with untreated or improperly managed BPH include acute urinary retention, recurrent urinary tract infections, gross hematuria, bladder stone formation, and, in severe cases, progressive renal impairment due to chronic back-pressure. Pharmacological treatments may introduce side effects such as orthostatic hypotension, ejaculatory dysfunction, or diminished libido, necessitating thorough patient counseling and careful clinical monitoring to mitigate adverse outcomes.
