Q

what’s the location of the prostate ?

A

The prostate is located just below the bladder and in front of the rectum. It is about the size of a walnut

located between the bladder and the penis. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body. The prostate secretes fluid that nourishes and protects sperm.

Q

what’s the sequle of the disease ?

A

1-Hyperplasia of epithelial and stromal components of prostate

2- then obstruction of urinary outflow in bladder

3- Increased activity of detrusor muscle(hypertrophy of the mucle )

4- this then lead to obstructive symptomas as Frequency, nocturia ,Poor flow and intermittent stream

and irriative symptomas as Hesitation and post voiding dribbling

Q

what’s the type of facia in the prostate ?

A

The rectoprostatic fascia (Denonvilliers’ fascia)

is a membranous partition at the lowest part of the rectovesical pouch. It separates the prostate and urinary bladder from the rectum.

prevent the invasion to the rectum

Q

why pt over age of 50 are more liable for the BPH ?

A

-because with increase the age the testestrone will decrease (testes) but the 5alpha reductase enzyme increase which convert the the testesrone into the dyhydrotestrone which is more potent (long half life )
will inhibit the apptosis and increase the growth and development of the cells as the basal and the luminal cells

Q

Prevalence of BPH …

A

+Men > 50 = 41% have symptoms of LUTS

+Only 18% have a diagnosis because of educational level of the pt so many of them diagnosis as UTI or overactive bladder

+Only 10% aware of drugs or surgery that will help it

A

Age over 50

obesity they have relation with hyperlipdema because the precsor of the androgen is the cholestrol

Q

Differential diagnosis of BPH …

A

-Poorly controlled diabetes
because DM lead to destruction of the scaral plexus that supply the detrusor muscle of the bladder

-Urinary tract infections
specailly the trigiontis which the most senstive part that lead to irrative symptomas

-Neurological disorders
as neurogenic bladder cause spastic to the bladder and obstruction

-Overactive bladder

-Drugs – diuretics, anticholinergics, antidepressants
these drugs act agnist the parasympathtic system and lead to increase the symathic and spasm of the bladder neck with retention

  • Lifestyle factors – caffeine, alcohol, xs fluids
  • Abacterial prostatitis

+bladder may be over active , neurogenic or infected

Q

pt with BPH and urinary retention indicate

A

paraxosmal incontinence

17
Q

Examination of BPH

A

  • enlarged bladder
    most important one

-enlarged kidneys
retention of urine

-constipation
the prostate in the front of the ampula of rectum

  • but may be the prostate is palpate in the suprapubic area
Rectal examination 
--------------------------------
Size and consistency of prostate gland
if the firm is BPH 
But if hard its CA
18
Q

difference between the acute and chronic retention ,,

A

acute is painful ,lead to enlarge bladder

while the chronic is less painful , the bladder enlagment lead to the bladder reach the epigastrium

Urinary retention is the inability to voluntarily urinate. Acute urinary retention is the sudden and often painful inability to void despite having a full bladder. 1 Chronic urinary retention is painless retention associated with an increased volume of residual urine and bladder that remains palpable after voiding

19
Q

Investigations pf BPH …

A

-Fasting blood sugar
to exclude the DM

  • erythrocyte sedimentation rate (ESR)
  • Urea and electrolytes (U&Es)
  • Renal function test
  • complete blood count
    for infection

level rises with increasing volume of prostate gland

  • Infection
  • haematuria

this special investigation done if we have suspison of ureter stricture rather than the prostate
or pt have neurogenic bladder

assess the dtrusor muscle contraction and tell us if the the removal of the prostate is indicated of not

Ultrasound 
-----------------------
-assess the size of prostate 
-congensity 
BPH have iso- echoic picture while CA have hypo-ehoic picture 

  • estimate residual urine
    by draining the bladder with a thin flexible tube (catheter) or by using ultrasound normal is (0-20cc )
    less than 50 mL is considered normal

Visual inspection of bladder and uerethra

  • used in dysuria or haematuria because pt may have tumor in the bladder in addation to the BPH
  • see if there is uerethra stricture

+ Renal function test
include
2 tests: ACR (Albumin to Creatinine Ratio) and GFR (glomerular filtration rate). GFR is a measure of kidney function and is performed through a blood test. … ACR is a urine test to see how much albumin (a type of protein) is in your urine.

+Post-void residual volume (PVR) is the amount of urine retained in the bladder after a voluntary void

20
Q

what’re the special investigation

done before the prostate removal

A
  • Uroflowmetry
  • Bladder pressure studies (cystometry)
21
Q

Uroflowmetry

A

max flow rate and volume of residual urine after voiding
this special investigation done if we have suspison of ureter stricture rather than the prostate
or pt have neurogenic bladder

– low flow rate indicates need for TURP

+Transurethral resection of the prostate (TURP) is a surgery used to treat urinary problems that are caused by an enlarged prostate. An instrument called a resectoscope is inserted through the tip of your penis and into the tube that carries urine from your bladder

22
Q

Bladder pressure studies (cystometry)

A

pressure measurement during filling and emptying (cystometry) gives information on over/under activity of detrusor muscle and obstruction of bladder outlet. Predicts response to treatment. Use antimuscarinics for over activity and turp for bladder outlet obstruction

assess the dtrusor muscle contraction and tell us if the the removal of the prostate is indicated of not

23
Q

Ultrasound

A

-assess the size of prostate
-congensity
BPH have iso- echoic picture while CA have hypo-ehoic picture

  • estimate residual urine
    by draining the bladder with a thin flexible tube (catheter) or by using ultrasound normal is (0-20cc )
    less than 50 mL is considered normal
24
Q

Urethroscopy

A

Visual inspection of bladder and uerethra

  • used in dysuria or haematuria because pt may have tumor in the bladder in addation to the BPH
  • see if there is uerethra stricture
25
Q

Assesment of the BPH

A

by international prostate symptom scale.
IPSC
it’s 7 symptoms for each 5 score

1 – 7 mild—–conservative TRT

8 – 19 moderate——-
20 – 35 severe———- both need surgery

this need hight awarnace of the pt

26
Q

so the surgery of BPH depend on

A

assessment and special investigation

27
Q

mangment of the BPH …

A

start from simple into more complex

Lifestyle modification
-----------------------------------
Reduce fluid intake
Stop diuretics if possible 
Avoid xs night time fluid intake/caffeine /alcohol
Empty bladder before long trips/meetings

Diabetes
UTI

Drug therapy
-------------------------
Alpha blockers as 
Tamsulosin and alfuzosin
Improve bladder and prostate smooth muscle tone
More effective 

5 alpha reductase inhibitors
Reduce prostate volume
Reduces risk of prostate cancer, increases risk of high grade disease

Combined therapy
Men with large prostate > 40g or PSA >4 or moderate to severe symptoms combined therapy will prevent 2 episodes of clinical progression per 100men over 4yrs. Much less effective for men with smaller prostates

Surgery
-------------------------------
-TURP( Transurethral resection of the prostate )
Greatest improvement in symptoms
5% severe haemorrhage risk
Requires GA

  • Ultrasound
  • Laser
  • microwave

Men with symptoms of urinary urgency, frequency, small, urine volumes and nocturia in the absence of serious obstructive symptoms are categorised as

A

over active bladder
