4. 1, Anatomic and Physiologic Overview of GUT
The urinary system comprises
The kidneys
Ureters
Bladder
Urethra
system is necessary for assessing individuals with
acute or chronic urinary dysfunction .
Mar-19 4
6. Are a pair of brownish-red structures located retro
Peritoneally
It is on the12th thoracic vertebra to the 3rd lumbar
vertebra in the adult
an adult kidney weighs 120 to 170 g and is 12 cm
long, 6 cm wide, and 2.5 cm thick.
The kidneys are well protected by the ribs, muscles,
fascia, perirenal fat, and the renal capsule, which
surround each kidney.
It has two distinct regions, the renal parenchyma and
the renal pelvis.
The renal parenchyma is divided into the cortex and
the medulla.
Mar-19 6
7. Each kidney contains approximately 8 to 18
renal pyramids.
The pyramids drain into 4 to 13 minor calices
that drain into 2 to 3 major calices that open
directly into the renal pelvis.
Each kidney contains about 1 million
nephrons, the functional units of the kidney.
Mar-19 7
8. The urinary system helps maintain homeostasis by
regulating water balance and by removing harmful
substances from the blood.
The blood is filtered by two kidneys, which produce
urine, a fluid containing toxic substances and waste
products.
Each kidney, the urine flows through a tube, the ureter,
to the urinary bladder, where it is stored until it is expelled
from the body through another tube, the urethra.
Mar-19 8
9. Inside the kidney, three major regions
The renal cortex borders the convex side
The renal sinus is a cavity that lies adjacent to the renal
medulla.
The renal medulla lies adjacent to the renal cortex.
It consists of striated
Cone-shaped regions called renal pyramids
(medullar pyramids)
Renal papillae, face inward.
Renal columns unstriated regions between the
Renal pyramids
Mar-19 9
10. Blood and nerve supply
Blood supply is delivered by the large renal Arteries.
The renal artery for each kidney enters the rena hilus
and successively branches into segmenta
Arteries and then into interlobar arteries, which Pass
between the renal pyramids toward the Renal cortex.
Autonomic nerves from the renal plexus follow the
Renal artery into the kidney through the renal hilus.
The nerve fibers follow the branching pattern of the
renal artery and serve as vasomotor fibers that regulate
blood volume.
Mar-19 10
11. Are narrow, muscular tubes, each 24 to 30 cm long
It originate at the lower portion of the renal pelvis and
terminate in the trigone of the bladder wall. There are
three narrowed areas of each Ureter:
-the ureteropelvic junction
-The ureteral segment near the sacroiliac junction,
-the ureterovesical junction.
The movement of urine from the renal pelves through
the ureters into the bladder.
Mar-19 11
12. Is a muscular, hollow sac located just behind the pubic
bone.
Is about 300 to 600 ml of urine in adult. In infancy, the
Bladder is found within the abdomen.
Is characterized by its central, hollow area called the
vesicle, which has two inlets
The bladder neck contains bundles of involuntary the
urethral sphincter known as the internal sphincter.
The portion of the sphincteric under voluntary control is
The external urinary sphincter at the anterior urethra, the
segment most distal from the bladder
Mar-19 12
13. The urethra arises from the base of the bladder:
In the male it passes through the penis
in the female, it opens just anterior to the
vagina.
In the male, the prostate gland, which lies
just below the bladder neck,surrounds
the urethra posteriorly and laterally.
Mar-19 13
14. The urinary system performs various roles that are
essential for normal
bodily homeostasis . These functions include
Urine formation
Excretion of waste products
Regulation of electrolyte, acid
Water excretion
Auto regulation of blood pressure
Mar-19 14
16. Assessments of GUT
• Radiographic Procedures of the Genitourinary
System
Types of Radiologic examination of the renal system
• Plain abdominal x-ray (KUB )
Kidney,
Ureter,
Bladder
Mar-19 16
17. It is x-ray of the abdomen.
• Involves no contrast media.
• Posses no risk to the person.
• Demonstrates the size, shape, & location
(position) of the KUB.
• Reveal any abnormalities: calculi in the
kidney/urinary tract, hydronephrosis,
cysts, tumors etc…
Mar-19 17
18. Examination of the renal system following the IV
injection of a radio-opaque dye filtered by the kidney &
excreted through the urinary tract.
Helps to identify the absence/presence, location, size,
&configuration of the kidneys, ureters, & bladder.
Helps to determine filling of the renal calices & pelvis.
Visualize different layers of the kidney &the diffuse
structure within each layer.
Visualize partial obstruction, Renovascular
hypertention, tumor, cyst, &congenital abnormalities.
Mar-19 18
19. Nursing responsibilities in patient
preparations
• Check for any allergies ¬ify for the physician
&the radiologist.
• A laxative may be prescribed the night before
examination to eliminate faces &gas from the
intestinal tract.
• Liquids may be restricted 8 to 10 hours before the test
to promote concentrated urine
• Describe the procedure &the sensations of warmth
&flushing of the face to the patient.
• Prepare the emergency drugs (epinephrine,
corticosteroids, and vasopressors) as well as oxygen,
tracheostmy, & other equipment, ready for immediate
therapy in case anaphylactic reaction occurs.
Mar-19 19
20. Contraindications of intravenous
urogram
– Poor renal function – can further compromise
function of the renal system because of
dehydrating effect & nephrotoxicity of IVP dye.
– Multiple myeloma – IVP dye may precipitate of
myeloma protein in kidney.
– Pregnancy – abdominal radiation should be
avoided.
– CHF – IVP dye has an acute osmotic effect that can
further compromise heart failure.
– Diabetes mellitus – Rapid deterioration of renal
function is common.Mar-19 20
21. URINALYSIS AND URINE
CULTURE
Urine color
Urine clarity and odor
Urine pH and specific gravity
Tests to detect protein, glucose, and ketone bodies
in the urine (proteinuria, glycosuria, and
ketonuria, respectively)
Microscopic examination of the urine sediment
after centrifuging to detect RBCs (hematuria),
white blood cells, casts (cylindruria), crystals
(crystalluria), pus (pyuria), and bacteria
(bacteriuria)
Mar-19 21
23. • The optimal PH of various body fluids differs but not
very much.
• The normal PH value is:
– 7.4 for arterial blood
– 7.35 for venous blood and intestinal fluid, and
– 7.0 for intercellular fluid.
Mar-19 23
24. • Acid-base balance is situation in which the PH of the
blood is maintained between 7.35 and 7.45.
• Imbalances occur in the form of:
– Alkalosis- arterial blood PH rises above 7.45
– Acidosis- A drop in arterial Ph to below 7.35
Mar-19 24
25. • Chemical Acid-Base Control /buffer system
–Bicarbonate
– phosphate
–Proteins
• Respiratory Acid Base Control
–Carbon dioxide
• Renal Acid Base Control
–Bicarbonate, acids, ammonium
Mar-19 25
26. Chemical Mechanisms (Buffers)
• Buffers are the first line of defense against
changes in H+ concentration. By acting as ‘H+
sponges’; buffers can bind H+ when the
concentration is too high or release H+ when
concentration is too low.
• Fluid buffers are composed of chemicals (e.g.
bicarbonate, phosphate) & proteins (e.g.
albumin, globulins, hemoglobin).
Mar-19 27
28. • This system is an effective buffer in urine and
intracellular fluid (ICF)
• Works much like the bicarbonate system
• System involves:
– Sodium Monohydrogen phosphate (Na2HPO4
2-)
H+ + HPO4
2- H2PO4
-
Mar-19 29
29. • Plasma and intracellular proteins are the body’s
most plentiful and powerful buffers
• Some amino acids of proteins have:
– Free organic acid groups (weak acids)
– Groups that act as weak bases (e.g., amino
groups)
Mar-19 30
30. Respiratory Mechanism
• When chemical buffers alone can not prevent
changes in body fluid PH, the respiratory
system is the second line of defense against
changes.

Mar-19 32
32. • The kidneys regulate extracellular fluid pH by:
– secreting H+,
– reabsorbing HCO3-, and
– producing new HCO3
-
• During alkalosis, excess HCO3
- is not bound by H+,
and is excreted, effectively increasing H+ in the
circulation and reversing the alkalosis.
• In acidosis, the kidneys reabsorb all the bicarbonate
and produce additional bicarbonate which is all added
back to the circulation to reverse the acidosis.
Mar-19 33
34. • Is characterized by PH below 7.35 & HCO-
3 level below 22m
E/L.
Over production of H+
– Excessive oxidation of fatty acids
– Hyper metabolism which result in deficiency of 02
– Excessive ingestion of acids
Under eliminations of H+
Under production of HCO3
-
Over elimination of HCO3

Mar-19 36
35. • Anorexia, nausea, vomiting
• Head ache, lethargy, confusion
• Kussmaul respiration
• Peripheral vasodilatation & ed cardiac out put
• Cold & clammy skin.
• Lab. (PH<7.35, HCO3
-<22mEq/L, PaCO2
(compansatory by the lungs), Hypercalemia
Mar-19 37
37. • Treatment is aimed at reversing the underlying disorder
– DKA, infections & diarrhea if present, renal failure
• NaHCO3 is administered IV to neutralize blood acidity
• Dialysis
• Fluids (NaCl solution) as required
• Adjusting potassium
– Monitor serum K+
– Rapid acting insulin to reverse drive K+ back in
to the cells
Mar-19 39
39. • Metabolic alkalosis is characterized by a blood PH
above 7.45 and an HCO3
- level above 26m E/L.
• the underlying mechanisms include a loss of H+
ions(acid), a gain in HCO3
- , or both.
Causes
Increase of base component
– Oral ingestion of bases (antacids, milk alkali
syndrome)
– Parentral base administration
– Excessive retention of HCO-
3
Mar-19 41
40. Decrease of acid component
– Prolonged vomiting, NG suctioning
– pyloric stenosis b/c only gastric fluid is lost in this
disorder
Potassium deficit
– Cushing’s syndrome
– Thiazide diuretics
Mar-19 42
43. Management
• Management usually directed to wards correcting the
cause of the condition
– Sufficient chloride supplementation for the kidney
to absorb sodium with chloride (allowing the
excretion of HCO-
3).
– Restoring normal fluid volume by administering
NaCl solution (because continued volume
depletion serves to maintain alkalosis).
Mar-19 45
44. – KCl in patients with hypokalemia to replace both
K+ &Na+ losses.
– Thiazide diuretics & NG suctioning are
discontinued.
– Antiemetics may be administered to treat
underlying nausea &Vomiting
Mar-19 46
46. Respiratory Acidosis (H2CO3 excess)
• Respiratory acidosis is a clinical disorder in which
the
– PH is less than 7.35 and
– the PaC02 is greater than 42mmHg.
• It is always due to inadequate excretion(removal)
of C02 with inadequate ventilation, resulting in
elevated plasma CO2 levels and thus elevated
H2CO3 level & usually causes ed PaO2 (due to
hypoventilation).
Mar-19 48
51. Management
• Directed towards improving ventilation
• Pharmacologic Mgt include:
– Bronchodilators
– Antibiotics (for respiratory infection)
– Thrombolytics (Anticoagulants for pulmonary
emboli)
• Air way clearance
• Adequate hydration
• Mechanical ventilation (in sever cases).
Mar-19 53
52. Respiratory Alkalosis (H2CO3 deficit)
• Respiratory alkalosis is a clinical condition in
which:
• the PH is >7.45
• PaCO2 is <38 mmHg.
• Because respiratory alkalosis can occur suddenly,
compensatory decrease in HCO3
- level may not occur
before respiratory correction has been accomplished.
Mar-19 54
53. Causes
– Any condition that increases respiratory rate &
depth like anxiety,
– Hyperventilation
– Hypocapnia
– Conditions that affect brain’s respiratory control
center
– Acute hypoxia secondary to high altitude,
pulmonary disease, severe anemia, pulmonary
embolus & hypotension
Mar-19 55
60. Fundamental concepts
Mar-19
• The human body functions when certain conditions are kept
with in a narrow range of normal value. These conditions
include:-
– Body temperature
– Electrolytes
– Blood PH
– Blood volume
Body fluid contains:
– water
– Electrolytes
– Non electrolytes (glucose, urine), and
– other substances
63
61. Body fluid compartments
Mar-19
• Approximately 55-60%of a typical adult’s weight
consists of fluids. These fluids are distributed in to
different compartments:
1. Intracellular fluid(ICF) compartment
– Is fluid with in the cells
– Located mainly (primarily) in skeletal muscle mass
– Contains approximately 2/3 (28L)of the total body
fluid
– Constitute 45% of body weight
64
62. Body fluid…
Mar-19
2. Extra cellular fluid(ECF) compartment
– Is fluid outside cells
– Contains approximately 1/3(15L) of body fluid
3. further divided in to
– Intravascular space
– Interstitial space
– Trans-cellular space
65
63. Factors that influence the amount of
body fluid include:
Mar-19
• Age
• Gender
• Body fat
68
64. FLUILD SHIFT
Mar-19
• Is the term used to classify the distribution of
water. This is of three types:
First space fluid shift
– normal distribution of fluid
Second spacing
– Is an excess accumulation of interstitial fluid
Third spacing
– Is losing of ECF in to spaces that do not have
contribution in the equilibrium of ICF and ECF.
69

– Acts as transport vehicle
– Aids in the hydrolysis of food
– Acts as medium and reactant for chemical
reactions
– Acts as a lubricant
– Cushions and acts as shock absorber

Mar-19
ii. Renal concentrating mechanisms
• The kidney controls the concentration of most of the
constitutes in body fluid, including water and
electrolytes. Mediated by the function of
Osmo receptors

• Stones are formed by crystallization of urinary
solutes (calcium oxalate, uric acid, calcium
phosphate, struvite & cystine)
• In 80% of pts with urolithiasis, gravel stones pass
spontaneously
• Men are affected more frequently than women,
& recurrences are possible
Mar-19 126
121. DEFINITION
Abnormal collection are formed
in the excretory passages of the
kidney, composed primarily of
calcium oxalates and phosphates; -
also called kidney stone, nephrolithsis,
and nephritic calculus
122. Causes & Predisposing factors
• Hypocalcaemia& hypercalciuria 2o to
hyperparathyroidism
• Renal tubular acidosis
• Multiple myeloma
• Excessive intake of Vit D milk & alkali
• Poor fluid intake& prolonged immobility
• Abnormal purine metabolism (hyperuricemia &
govt )
• Chronic infection with urea splitting bacteria
Mar-19 128
123. • Chronic obstruction by foreign bodies in the
UT
• Excessive oxalate absorption in inflammatory
bowel disease Complications obstruction
Infection,& Impaired renal function
Mar-19 129
124. The five major categories of stone are
1. calcium phosphate
2. calcium oxalate
3. uric acid
4. Cystine
5. striuvite (magnesium ammonium phosphate)
Mar-19 130
125.
126. Clinical manifestations:

• A percutaneous nephrostomy or a percutaneous
nephrolithotomy (which are similar procedures)
Mar-19 134
129. Surgery:
• Nephrolithotomy: is an incision into the
kidney to remove stone.
• Pyelolithotomy: is an incision into the renal
pelvis to remove stone.
• Ureterolithotomy: is an incision into the
ureter to remove stone.
• Cystotomy: indicated for the bladder calculi.
Mar-19 135
133. • The enlargement of the prostate causes
narrowing of the urethra and upward pressure
on the lower border of the bladder.
• Urinary retention may develop, as the body
has a harder time emptying the bladder.
• Hydronephrosis and dilation of the renal
pelvis and ureter are complications of the
urinary retention due to overgrowth of the
prostate.
Mar-19 139
134. • Exact causes is unknown
• Aging.
• Family history.
• Ethnic background.
• Diabetes and heart disease.
• Lifestyle.
Mar-19 140
135. • Urinary hesitancy—difficulty initiating stream
of urine due to pressure on urethra and bladder
neck
• Urinary frequency—need to urinate frequently
due to pressure on bladder
• Urinary urgency—need to get to bathroom
quickly to urinate due to pressure on bladde
Mar-19 141
136. • Nocturia—need to get up at night to urinate
due to pressure on bladder
• Decrease in force of urinary stream
• Intermittent stream of urination
• Hematuria
Mar-19 142
137. Diagnostic evaluation
• Urography shows high volume of post-void
residual urine.
• PSA (prostate-specific antigen) may be mildly
elevated.
• Prostate ultrasound shows hypertrophy.
• Digital rectal exam reveals fullness of prostate and
loss).
• Urinalysis may show microscopic hematuria.
• BUN and creatinine levels may elevate, if renal
function is impaired
Mar-19 143
138. TREATMENT
• Administer alpha1-blockers for symptom relief:
• doxazosin
• tamsulosin
• terazosin
• Monitor blood pressure; hypotension may be
side effect of some alpha1-
blockers.
Mar-19 144
139. • Administer finasteride to relieve symptoms by
shrinking prostate gland.
• Monitor PSA levels periodically.
• Monitor renal function.
• Surgical removal of prostate tissue to relieve
pressure.

for irrigation, another is for drainage, and the
third to inflate a balloon that holds the catheter
in position.
• Monitor intake and output.
• Monitor vital signs for changes.
• Monitor postoperative patient’s bladder
irrigation: Monitor the amount of fluid instilled
and the amount of fluid returned an
Mar-19 147
142. • Document color of urinary output
postoperatively; the greatest risk of
hemorrhage is the first day after the operation.
• Monitor for bladder spasms which may
indicate blocked catheter drainage
postoperatively.

testicles
• N/V, Fever
• Discharge from penis
• Prostate enlargement and tenderness
Mar-19 152
147. Causes - A number of bacterial & viral
organisms can lead to orchitis.
Bacterial orchitis – Most often resulted from
epididymitis, an inflammation of the coiled
tube (epididymis) that connects the vas
deferens and the testicle. Often the cause of the
infection is an STD, particularly gonorrhea or
Chlamydia.
Mar-19 153
148. Viral orchitis - Most cases are the result of
mumps. The mumps virus can spread from the
salivary glands to other parts of the body,
including the testicles.
Physical trauma – particularly in individuals
with hazardous occupation
Thermal – (radiation) decrease testicular
secretion & can cause atrophy of the testis.
Mar-19 154
149. Risk factors
• Not being immunized against mumps; Being
older than 45; Recurring UTI
• Surgery that involves the genitals or urinary
tract, b/s of the risk of infection
• Malformations in the urinary tract present at
birth (congenital)
• High-risk sexual behaviors that can lead to
STDs
Mar-19 155
150. Complications
• Orchitis may cause the affected testicle to
shrink (atrophy).
• Scrotal abscess
• Rarely it can impair fertility
Mar-19 156
151. Treatment
– Symptomatic Rx for viral orchitis: analgesics,
bed rest, elevating the scrotum and applying
cold packs.
– Antibiotic for bacterial orchitis
– Protection of STIs & Sexual partner
management if the cause is an STI
– Immunization against mumps
Mar-19 157
152. 7. Phimosis
• It is a condition in which the foreskin is
constricted so that it can not be retracted over
the glans penis.
• Cause – congenitally or inflammation
• Treatment - instruction to clean the preputial
area.
- Circumcision is the only management
Mar-19 158
153. 8. Paraphimosis
• It is a condition in which the foreskin is
retracted behind the glans penis & because of
narrowing and subsequent edema can not be
reduced back to its position.
• Treatment – manual reduction but
circumcision is the best management.
Mar-19 159
154. Phimosis is a tight prepuce that cannot be
retracted over the glans
Paraphimosis is a tight prepuce that, once retracted,
cannot be returned.
