Prostate Gland Anatomy
- The prostate gland is a small, walnut-sized gland located in front of the rectum and below the bladder in men.
- It surrounds the urethra and plays a crucial role in the male reproductive system.
- The prostate gland has three main zones:
- Peripheral zone (75% of the gland): This is the outermost layer and is where most prostate cancers originate.
- Transition zone (25% of the gland): This is the middle layer and is where benign prostatic hyperplasia (BPH) occurs.
- Anterior fibromuscular stroma: This is the innermost layer and consists of smooth muscle and fibrous tissue.
PSA Definition
- Prostate-specific antigen (PSA) is a protein produced by the prostate gland.
- It is secreted into the seminal fluid and is present in small amounts in the blood.
- PSA is used as a biomarker to detect and monitor prostate cancer.
Physiological Role of PSA
- PSA plays a role in the liquefaction of semen after ejaculation, allowing sperm to swim more freely.
- It also helps to neutralize acidic environments in the female reproductive tract.
Significance of PSA as a Biomarker
- Elevated PSA levels can indicate prostate cancer, BPH, or prostatitis.
- A digital rectal examination (DRE) and PSA test are often used together to screen for prostate cancer.
- PSA levels can also be used to monitor the effectiveness of treatment and detect recurrence.
Homoeopathic Therapeutic Medicines
- Indications:
- Saw Palmetto: For enlarged prostate, urinary frequency, and difficulty urinating.
- Berberis: For urinary frequency, urgency, and pain.
- Cantharis: For painful urination and urinary retention.
- Sarsaparilla: For prostate enlargement and urinary frequency.
Surgical Anatomy of Prostate Gland
- The prostate gland is surrounded by the following structures:
- Bladder neck
- Urethra
- Prostatic sinus
- seminal vesicles
- Vas deferens
- Rectum
- The prostate gland is supplied by the following arteries:
- Dorsal artery of the penis
- Inferior vesical artery
- Middle rectal artery
- The prostate gland is innervated by the following nerves:
- Pelvic splanchnic nerves
- Pudendal nerve
Management and Treatment
- The management of prostate cancer depends on the stage and grade of the cancer.
- Treatment options include:
- Active surveillance: Monitoring the cancer with regular PSA tests and DREs.
- Surgery: Radical prostatectomy to remove the prostate gland.
- Radiation therapy: External beam radiation therapy or brachytherapy to kill cancer cells.
- Hormonal therapy: Medications that block testosterone production to slow cancer growth.
- The treatment of BPH includes:
- Watchful waiting: Monitoring the symptoms and waiting for them to progress.
- Medications: Alpha-blockers or 5-alpha-reductase inhibitors to reduce symptoms.
- Surgery: Transurethral resection of the prostate (TURP) to remove excess tissue.
