
The structures of this system precisely maintain the internal
chemical environment of the body (Smeltzer & Bare, 2007, pg. 1255)
Comprised of:

Upper urinary tract




Kidneys: “balance the urinary excretion of substances against
the accumulation within the body through ingestion or
production”.(Balck Hawkes & Keene, 2001, p.732)
Ureters: connect the kidney from the renal pelvis to the bladder.
Lower urinary tract


Bladder: hollow elastic organ that holds urine
Urethra: extends from base of bladder to the surface of the
body.

 X-ray and other imaging modalities
 Urological Endoscopic Procedures
 Biopsy
 Urodynamic Tests

Goal of Clean Catch Urine
(Mid Stream)
To minimize
contamination of the
specimen by organisms
on the skin
Do you remember how to collect
a midstream sample ???
A 12 or 24 hr specimen??
Renal Function Tests: Table 43-4
BUN (Bld urea nitrogen)
(table 43-4)
Urea forms in the liver, along with CO2, constitutes the final
product of protein metabolism. The amount of excreted urea
varies directly with dietary protein intake. The test for BUN
which measures the nitrogen portion of urea is used as an index
of glomerular function in the production & excretion of urea.
Thus, serves as an index of renal functioning.
A marked increase in BUN = severe impaired renal function


Adult: 7-18 mg/dl or
2.5-6.4 mmol/L
Elderly 8-20 mg/dl or
2.9-7.5 mmol/L

Child 5-18 mg/dl or
1.8-6.4 mmol/L
Urine Creatinine (table 43-4)



Amino acid waste product derived from muscle creatine (a product of
protein metabolism)
All creatinine filtered by kidneys in a certain timeframe goes into the
urine, creatinine levels thus are equal to the glomerular filtration rate.
Disorders of kidney interfere with normal secretion of creatinine
Thus creatinine measures effectiveness of renal functioning (serum
Creatinine)
Keep in mind that rate normally decreases as we age



urine creatinine men 0.8 -1.8 g/24h
urine creatinine women 0.6 - 1.6 g/24h
blood creatinine: 0.4-1.5 mg/dl
Renal Function Tests: Table 43-4

(nephrolithiasis) but can form or migrate
to lower urinary system.
Usually asymptomatic until they pass into
lower tract.
Primary causes are 1) urinary stasis, 2)
supersaturation of urine with poorly
soluble crystalloids (leads to precipitation
of crystals).

Bladder Trauma





blunt or penetrating injury to bladder that
may cause bladder rupture.
Often the result of car accidents, seat belt
pressure against distended bladder.
Urine spills into peritoneal cavity, causing
peritonitis & pelvic cellulitis.
Manifestations: hematuria, pain, difficulty
voiding.
Usually require surgery, post-op have a
urethral or suprapubic catheter.
Ureteral trauma

usually the result of
surgical accident.
Other causes gunshot
or stabbing


Symptoms include flank
pain, hematuria,
eventually paralytic
ileus, sepsis
Treatment is surgical
repair
Urethral trauma
• May result from pelvic fracture (falling on
object such as bar on bike)
•Symptoms include inability to void or
altered stream, swelling in groin, scrotum
or inguinal area, may lead to sepsis and
necrosis.
•Complications include urethral strictures
or impotence in men.
•Treatment may be medical (catheter for
several weeks or surgery)
Renal trauma
Renal Trauma





Traffic accidents & falls most
common cause
Five categories
Complications include hemorrhage,
abscess, fistula, HT
Treatment may be medical or
surgical- watch & see
Manifestations:
 Type of injury is key
 May have hematuria, shock,
flank pain, palpable mass,
paralytic ileus, bruising
over flank
Renal Cancer





85% of renal tumors are malignant
Most common between ages of 50 and 70
Cause unknown but some links between chemicals and
cancer, I.e. smoking, exposure to lead.
Tumor starts in renal cortex and lead to obstruction,
renal failure, hemorrhage invasion of surrounding tissue
Symptoms: painless hematuria, flank pain, palpable
mass (often delayed diagnosis – 35% have mets when
diagnosed)
Renal cell carcinoma with venous
invasion.





Stage I: confined to kidney
capsule; survival rate 65%
Stage II: extends beyond
capsule into fatty tissue; S.R
40%
Stage III: regional lymph
nodes, renal vein, possibly
IVC
Stage IV: distant mets, often
lungs & mediastinum
Survival rare in III and IV
Management




Surgery: partial or radical nephrectomy is
usual treatment
Radiation therapy: with chemotherapy
and/or surgery. Pre-op to shrink tumor or
post-op for residual cells or mets
Chemotherapy: seems to be less effective
b/c of slow growth rate. Vinblastine is most
effective single agent with response rate of
25%
Immunotherapy: fairly new, stimulates
immune system
Renal surgery
Nursing Management



Pre-op teaching and emotional support
Post-op there is high risk for hemorrhage, monitor
for signs of bleeding (may be incisional or
internal). Also risk for pneumothorax.
Post-op care requires:
 DB & C (how can you help??)
 Monitor urine output
 Pain Management
 Monitor GI status (watch for ileus)
Bladder Cancer



Appears to be the result of exposure of
bladder wall to carcinogens – smoking,
asbestos, radiation & chemo
Gross hematuria is often the first sign.
Identified through cystoscopy, IVP, CT,
MRI, blood work (CEA)
Treatment includes surgery, radiation
therapy and chemo
Just read on own
Cystoscopy
Surgery


Transurethral resection, partial
cystectomy, radical cystectomy & urinary
diversion
Urinary diversion procedures:




Ileal conduit
Indiana pouch
Neobladder
Palliative procedures: percutaneous
nephrostomy or pyelostomy (tube in renal
pelvis), ureterostomy
Indiana Pouch Procedure
Indiana Pouch



Urine is removed by
inserting a thin tube
(catheter) into the stoma
when the pouch is full.
A bag is not required and
the patient simply wears a
bandage over the stoma.
The patient is then taught
to catheterize the reservoir
to drain urine at regular
intervals during the day.
Hypertension
May be cause of renal failure or effect
e.g. Renal artery stenosis decreases blood flow to
the kidney. This activates the renin-angiotensinaldosterone system which increases BP. Renal
hypertension results from the kidney’s inability
to excrete salt and water.


Sustained high BP causes nephrosclerosis &
damages arteries and arterioles
Renal vascular disorders


Renal artery disease
Renal vein disease
Congenital
Abnormalities




May involve abnormalities in
number, position or size.
Agenesis: means absence of
one or both kidneys
Sizes: small with or without
functioning tissue
Horseshoe kidney: both
kidneys are joined, in lower
lumbar region

Susceptible to hydronephrosis,
infection and calculus formation
Polycystic Kidneys




Hereditary disease
characterized by cyst
formation & massive
enlargement – affects both
adults & children.
Disease is slow & progressive
results in CRF
No cure so management is
conservative, supportive
medical treatment
Eventually needs dialysis or
transplant
