1. Disorders of the Urinary System
Can you guess one?

2. Renal Calculi (Kidney Stones)
Made of crystals of calcium phosphate and uric acid
Gradually they get larger until they block ureters
First sym severe pain
Other sym nausea and vomiting, frequency, chills, fever, hematuria
Diagnosis by symptoms, ultrasound, or x-ray
Rx –increase fluids to flush out stone, medications, and if needed LITHOTRIPSY

3. Lithostripsy Surgical procedure to remove kidney stones
Shock waves hit dense stones and break them up
Done on outpatient basis

4. Glomerulonephritis Two types
Acute- occurs in some children about 1 to 3 weeks after a bacterial infection, usually a strep throat. The illness is treated with antibiotics and recovery takes place.
Chronic- occurs when the filtration membrane may be permanently affected. There is diminished functions of the kidney, which may result in kidney failure.
Disease which injures the glomerulus.
The filtration process is affected. Plasma proteins are filtered through and protein is found in the urine as albumin and red blood cells are present.

5. Nephritis Inflammation of the kidney (kidney infection)
Incontinence – involuntary urination

6. Cystitis
Inflammation of the mucous membrane lining of the urinary bladder
Most common cause – E.Coli
Sym- DYSUIA (painful urination) and frequency
Usually in females (shorter urethra)
Rx - antibiotics

7. Kidney Failure ACUTE KIDNEY FAILURE•
Caused by nephritis, shock, injury, bleeding, sudden heart failure or poisoning•Symps – OLIGURIA (scant urine) or ANURIA (no urine produced)
CHRONIC RENAL FAILURE - gradual loss of function of nephrons

8. Urinary Disorders Renal Failure
Chronic kidney disease leads to a buildup of fluid and waste products in the body.
How are these systems affected by renal failure?

9. Hemodialysis Used for kidney failure
Involves the passage of blood through device with semipermeable membrane
Dialysis serves as substitute kidney
Blood from patient flows through machine and is filtered
Can be done at home or in clinic
Takes 2-4 hours, 2-3 times a week.

10. Urinary Disorders Renal Failure How is it treated? Peritoneal dialysis
What is the process involved in this treatment?

11. Kidney Transplant As a last resort
Involves donor organ from someone with a similar immune system
Main complication - rejection

12. Definitions Enuresis Glycosuria Nocturia Polyuria Bedwetting
Sugar in urine
Frequent urination at night
Large amounts of urine

13. Definitions Continues
Pyuria
Anuria
Hematuria
Diuretic
Pus in urine
No urine produced
Blood in urine
Drug or substance to increase urine production

14. Essential Questions
What are the functions of the urinary system?
What are some disorders of the urinary system?
How are disorders of the urinary system treated?
How do you relate the body’s hormone control to the urinary system?

17. PPT and BM Three and Four
Take two disorders on this bubble map and draw a picture of the part of the kidney that it affects and color the picture of the disorder. Then in the picture draw the signs and symptoms, and treatment

BM Four
Using the one disorder on this bubble map and draw a picture of the part of the kidney that it affects and color the picture of the disorder. Then in the picture draw the signs and symptoms, and treatment
For peritoneal dialysis discuss why someone would do this rather than hemodialysis.
