ABSTRACT: Benign Hypertrophy of Prostate (BPH) or Adenomatous enlargement of the prostate is the nonmalignant enlargement of the prostate gland. It refers to stromal and glandular epithelial hyperplasia that occurs in the periurethral transition zone of the prostate that surrounds the urethra.1 This article represents a brief overview of BPH and homoeopathic view point along with diagnostic and management approaches after critical analysis of different source books so as to enable the reader to get all aspects of the disease on a one common plane.

KEYWORDS: BPH, Homoeopathy, IPSS, Postvoid.

ANATOMY: The prostate develops around 12th week of intrauterine life. It has 5 lobes: Anterior, posterior, 2 lateral and 1 middle lobe or median lobe. Median lobe is situated in between the two ejaculatory ducts and the urethra.

The classification of the prostate into different zones was done by McNeal. It is divided into the peripheral zone (PZ), which lies mainly posteriorly and from which most carcinomas arise, and a central zone (CZ), which lies posterior to the urethral lumen and the ejaculatory ducts as they pass through the prostate.

There is also a periurethral transitional zone (TZ), from which most benign prostatic hyperplasia (BPH) arise.2

EPIDEMIOLOGY: Benign prostatic hyperplasia (BPH) mainly effects men of increasing age. 

By age 50 years, about 50% of men are diagnosed, by 80 years, 90% of men are diagnosed. The greatest prevalence occurs among men ages 70 to 79 years.3,4

PATHOPHYSIOLOGY: BPH affects both glandular epithelium and connective tissue stroma to variable degrees. BPH typically affects the submucous group of glands in the transitional zone, forming a nodular enlargement. This overgrowth compresses the PZ glands into a false capsule and causes the appearance of the typical ‘lateral’ lobes. 

ASSOCIATED THEORIES FOR BPH:

Hormonal theory: 

Within the prostate, testosterone is converted to Di hydro testosterone (DHT) by the help of enzyme 5-α reductase, this androgen thought to be the main mediator of prostatic hyperplasia. The clinical importance of DHT became clear when patients treated with orchiectomy and 5-alpha-reductase inhibitors (which stop conversion of testosterone to DHT) showed decrease in BPH symptomatology. With increasing age, levels of androgens come down and there is corresponding increase in levels of oestrogen which stimulates the prostatic gland and produces BPH.

Role of cytokines:

Cytokines contribute to prostate enlargement by an inflammatory response and by inducing epithelial growth factors. As the prostate enlarges due to hyperplasia, the portion of the urethra that passes through the prostate is compressed, lead to decrease urinary outflow and cause obstructive symptoms. The patient develops bladder hyperactivity, inflammation, and distension as bladder smooth muscle cells enlarge to maintain urine flow in response to resistance from prostatic obstruction. These changes cause oxidative stress and free radical formation, as well as alterations to the alpha-adrenergic nerves of the bladder, resulting in storage symptoms. 

Neoplastic theory:

According to this theory there is proliferation of all elements of prostate like fibrous, muscular and glandular.

COMPLICATIONS OF BPH:

Urethral changes: Urethra gets compressed, elongated and convert into a narrow longitudinal slit lead to urinary flow obstruction. This effect is more with median lobe enlargement (due to enlargement of subcervical glands).

Bladder changes:   Bladder muscles hypertrophy lead to formation of fasciculations.

Retention of urine in diverticuli lead to secondary infection and stone formation.

Changes in the ureter and kidneys: Bilateral hydronephrosis and bilateral hydroureter are the end result of BPH. Which may lead to renal failure. 

RISK FACTORS: Increasing age, metabolic syndrome, family history of BPH, obesity, history of diabetes, black race, a diet high in starches and meat, excessive alcohol intake, smoking may be a risk factor for BPH, a sedentary lifestyle can increase the risk of developing BPH or intensify the severity of lower urinary tract symptoms (LUTS) in patients who already have the condition.

CLINICAL FEATURES:

Storage Symptoms Voiding symptoms
Urinary frequency Difficulty initiating urinary stream
Urinary urgency Urinary hesitancy
Urinary incontinence Straining to void
Nocturia Decreased urinary flow
Dysuria Intermittency
Dribbling
Incomplete bladder emptying

Frequency: increased frequency of micturition particularly at night is the earliest symptoms.

Nocturia occurs, patient get up in the middle of the night twice or thrice to pass urine.

Urgency: due to prostatic enlargement there is vesicle introversion of sensitive mucous membrane of prostatic urethra within the bladder, it cause internal sphincter to stretch and prevents contraction. It results urgent desire to pass urine.

Haematuria: due to prostatic congestion.

Difficulty in micturition.

Acute and chronic retention of urine.

Symptoms of uraemia: It include headache drowsiness and even haematemesis.5

DIFFERENTIAL DIAGNOSIS:

The following conditions can coexist with Bladder outflow obstruction (BOO):

  • Idiopathic detrusor muscle over activity 
  • Neuropathic bladder dysfunction due to diabetes, strokes, Parkinson’s disease 
  • Degeneration of bladder smooth muscle giving rise to impaired voiding and detrusor instability
  • Bladder neck stenosis
  • Bladder neck hypertrophy
  • Prostate cancer
  • Urethral strictures

DIAGNOSIS:

Careful History Taking: specific questions about storage and voiding symptoms

  • The American Urological Association Symptom Index (AUASI) and The International Prostate Symptom Score (IPSS) are subjective questionnaires that can be used to help evaluate lower urinary tract symptoms and their effect on patients suffering from BPH.
  • The score is classified as mild (0-7), moderate (8-19), or severe (20-35).

Digital rectal examination (DRE):

Done to assess the size, shape, and consistency of the prostate gland. Done in left lateral position (or in knee elbow position).The urinary bladder must be empty before examination. The index finger is usually used and should face the anterior surface of the rectum. An enlarged prostate is soft, smooth, boggy, mobile, and with an central sulcus. Persistence of median sulcus is a definite sign of this condition which is often obliterated in carcinoma. The rectal mucosa moves freely over the gland. (in case of carcinoma rectal mucosa not moves freely) The prostate may not be felt enlarged if only the median lobe is enlarged. Any nodules or indurations, which may suggest prostate cancer.

Grading of prostate:

  1. The prostatic lobes protrude minimally into the rectal lumen by 1-2 cm, the median sulcus is palpable
  2. Prostatic lobes protrude > 2 cm but < 3 cm into the rectal lumen and median sulcus is obliterated
  3. Protrusion of 3-4 cm
  4. Protrusion > 4 cm, most of the rectal lumen is filled by the projecting prostatic lobes.

Prostate-specific antigen (PSA) level:

PSA levels often correlate with prostate size; normal value of PSA is below 4ng/ml. Value of PSA increase in BPH, prostatic carcinoma, prostatitis etc. 

Urinalysis:

Urine is examined for glucose and blood; a midstream specimen should be sent for bacteriological examination, and cytological examination may be carried out if carcinoma in situ is thought possible. 

Maintain voiding diaries:

Documenting the time voided, volume voided, and associated activities (such as fluid intake) in a voiding diary may help in BPH diagnosis, especially in patients with urinary frequency. 

Blood urea and creatinine: raised levels indicate renal failure

Prostatic ultrasound:

Trans abdominal or transrectal prostatic ultrasound evaluate the size, shape, anatomy, and potential pathology of the prostate, also can assess the bladder and postvoid residual urine.

Measuring postvoid residual volume:

A postvoid residual volume measurement is recommended for patients with moderate or severe symptoms, defined by an IPSS score of 8 or greater.

Uroflowmetry: patient is asked to void urine from is full bladder into the flow meter than flow rate is assessed.

  • Peak flow rate: normal is 20 ml/sec
  • Doubtful peak obstruction is 10 -15 ml/sec
  • Definite peak obstruction is < 10ml/sec

Cystourethroscopy:

Inspection of the urethra, the prostate and the urothelium of the bladder should always be done immediately prior to prostatectomy, whether it is being done trans urethrally or by the open route to exclude a urethral stricture, a bladder carcinoma and the occasional non-opaque vesical calculus.2,5,6

DISCUSSION & CONCLUSION:
Men with benign prostatic hyperplasia (BPH) often find the condition stressful. Symptoms like urinary urgency may disturb even the most relaxed fellow, and nighttime urination that interrupts sleep can only add to mental distress.
Keeping this in mind, proper diagnosis, investigations and management becomes matter of prime importance for well being of the patient, which is summarised in this article. Homoeopathy is a specialized system of medicine which treats the patient and not the disease. Homoeopathy believes in holistic individualized approach, and corrects disturbances in the vital force. However, use of therapeutically indicated medicines have been proved beneficial time to time.
