By: Christopher, Kevin Wilson and Matt

Functions of a Healthy Kidney

• Processing machines

• “Processes 200 quarts of blood to sift out about 2 quarts of waste products and extra water”

• Filters waste materials from the blood

Functions of a Healthy Kidney

• Waste material filtered is called urine

• Urine flows from kidneys to the bladder through the ureters.

• Urine is stored in the bladder until excreted

Physical Characteristics of a Healthy Kidney

• Bean-shaped organs• Each person usually has

2 kidneys, some are born with 1

• Left kidney usually longer and narrower than right

• Each kidney is about the size of your fist

• Mass of adult kidney– male: 125 - 170 g– female: 115 - 155 g

Physical Characteristics of a Healthy Kidney

• Bean-shaped organs• Blood with waste goes

through the blue tube• Clean blood comes out

from the red tube• Urine goes through the

beige tube to the ureter to the bladder

Renal cell carcinoma

• A type of kidney cancer• Affects 3 of 10 000

people in the U.S• Mostly affects men of 50

– 70 years of age• A tumour grows out of

the kidney• Spreads easily to other

organs, esp. lungs

Renal cell carcinoma

• Smoking is the most prominent risk factor

• Symptoms:

– Blood in urine

– Abnormal urine colour (dark, rusty, or brown)

– Flank, back and abdominal pain

– Weight loss

– Emaciated, thin, malnourished appearance

– Enlargement of one testicle

– Swelling of the abdomen

Kidney Tumor - CT Scan

Renal cell carcinoma• Treatment:

– Surgical removal of all or part of the kidney

– Hormone treatments and immunotherapy with medications such as alpha-interferon and interleukin may reduce the growth of the tumor in some cases

– Chemotherapy used in some cases– Radiation therapy usually not successful

• Cure is unlikely unless all cancer can be removed with surgery

• Can come back even if removed surgically

• CAN cause death– about 12,000 people in the U.S. die every

year
