Q

Kidney Functions

KNOW BOLD!!!

A

Removes metabolic waste products and excess water FROM the body***

  • Excretes metabolic wastes and foreign chemicals
  • Gluconeogenesis* in times of fasting*
  • Acid-base balance
  • Water and electrolyte balances
  • Arterial blood pressure
  • Secretion, metabolism, excretion of hormones
  • Regulation body fluid osmolality and electrolyte conc.

Q

Pathogenesis of Kidney Disease

Angiotensin II NORMAL function?

A
  • Vasoconstriction of arterioles and arteries
  • *Must keep pressure adequate for filtration of blood
    • AKA→ manages blood pressure for adequate filtration***

Q

Angiotensin II attracts __________ and this changes structure of the glomerulus in kidney*

aka NOT helpful in kidney disease!

A

Attracts inflammatory cells!

Cascade→

  • Cytokines, growth factors released
  • Changes structure of glomerulus
  • => REDUCED surface area for filtration***
    • SO…we don’t want TOO MUCH angiotensin II***

NOTE: this is ALL due to the inflammation!

W/ Progression of Dis.

A

drowsy/confusion, change skin pigment, excessive thirst, insomnia, edema, peripheral neuropathy (notice trend, LOTS of things can cause this!!! remember this is a circulation/filtration problem so makes sense!!!)

Q

Stages of Chronic Kidney Disease

NOTE: happens slow, 5 stages. In ea, kidneys don’t work as well as the stage before. W/ tx and lifestyle changes, YOU CAN help slow or stop kidney dis. from getting worse!

A
  • Stage 1→ Kidney damage w/ normal kidney function
    • GFR= 90 or higher
  • Stage 2→ Kidney damage w/ mild loss of kidney function
    • GFR= 89-60
  • Stage 3a→ Mild-Moderate loss of kidney function
    • GFR= 59-45
  • Stage 3b→ Mod-Severe loss of kidney function
    • GFR= 44-30
  • Stage 4→ Severe loss of kidney function
    • GFR= 29-15

Q

Promotion of Phys Activity in CKD

A
  • VITALS ARE VITAL!
    • BP and RPE
  • Long warmup (when approp.)→ aerobic, strength
  • Cool-down

32
Q

Skeletal Changes in CKD

****SEE FIG. 18-7, GOODMAN, P.971

GFR, Phosphate retention, Calcitrol

This is what you think of initially as soon as you see “Skeletal changes in CKD”

A

DEC GFR

INC Phosphate retention

DEC Calcitrol

Know this!!!!!!!

33
Q

Skeletal Changes in CKD

DEC GFR, INC phosphate retention, DEC calcitrol

Explain the cascade of events that follows!

BE ABLE TO EXPLAIN VERBATIM!!!

A
  1. Changes impair normal processes of bone mineralization
  2. Parathyroid hormone (PTH) mobilizes calcium from SK system to “help”→ mobilizes all this Ca+ bc thinks its doing good and helping!
  3. Results→ HypERphosphatemia and HypERcalcemia

**Progression of vicious cycles leads to Bone Turnover===> rickets, osteomalacia, osteopenia, soft tissue calcification

Clinical Presentation

Metatstatic sites: in order

A

48
Q

Renal Cell Carcinoma RCC:

More clinical presentation

A
  • 50% cases discovered incidentally bc renal cx’s are silent
  • NON-specific sx’s→ malaise, anemia, wt loss
  • Fever, HTN, hepatic dysf and hypERcalcemia occur bc hormone production by tumors
  • 25-30% have metastatic dis by time of dx→ 5yr survival of 0-7% in presence of mult. mets
49
Q

Renal Cell Carcinoma: Summary of Medical Mx:

PRIMARY FEATURE

A

Renal parenchymal mass

50
Q

Renal Cell Carcinoma: Summary of Medical Mx:

PRIMARY TX:

A

SURGERY

  1. Radical nephrectomy
  2. Removal of metastatic lesions does not improve survival*
51
Q

Renal Cell Carcinoma: Summary of Medical Mx:

More on this..

A
  • Dx imaging→ abdominal US, MRI, CT
  • Chemo NOT gen. effective
  • 40% of locally removed renal tumors recur***
52
Q

RCC: Staging

ALL

A
  • I= tumor w/in capsule
  • II= tumor invades perirenal fat
  • III= tumor extends into renal vein or regional lymphatics
  • IV= distant mets present
53
Q

Bladder Cx:

Overview

A
  • 4th leading cause of cx in men, 8th leading cause in all of U.S.A
  • Risk Factors:
    • smoking (2x more likely to dev.), male/Euro descent/55+ yrs old, exposure to chemicals/toxins, bladder conditions, chronic inflamm, chemo/radiation
54
Q

Bladder Cx:

Pathogenesis

A
  • Contact chemical carcinogenesis (urine-soluble carcinogens contact urinary epithelium for long pds time), genetic defects in tumor-suppressed gene, inability to repair DNA w/ damage

Aka waste products/carcinogens keep contacting bladder wall= irritation***

55
Q

TNM explained:

A
  • T (Tumor) = how far the main (primary) Tumor has grown thru the bladder wall AND whether it has grown into nearby tissues
  • N (Nodes) = any cx spread to lymph nodes near the bladder
  • M (Metastasized) = if cx has spread to distant sites (mets)
64

M=

Metastases

67
Q

Bladder Cx Staging:

T= Tumor

T1 vs T2

A

74% of bladder tumors= T1 or T2

  • T1→ tumors thru basement memb. and invaded into submucosa/lamina propria but NOT muscularis propria
  • T2→ tumors invade muscular propria
68

N= Nodes

N0, N1, N2

A
  • N0→ NO involvement
  • N1→ nodes near bladder
  • N2→ nodes further away

Lung→ Liver→ Bone

70
Q

Bladder Cx: Surgical Intervention for Early Stage

Stage 0,1

  • For early, superficial tumors
  • scope thru urethra→ remove lesions
  • tumor bed tx’d w/ laser/electric current to destroy tissue

*F/b BCG= intravesical immunotherapy

71
Q

Bladder Cx: Surgical Intervention for Early Stage

Transurethral Resection Complications:
