1

Nephron Function

-filter blood
-reabsorb fluid
-forms filtrate of protein-free plasma
-maintain body fluid volume
-maintain electrolyte composition
-maintain body pH

2

Kidney receives _____& of cardiac output

-20%

3

Pathway

-blood vessel
-bowman's capsule
-glomerulus
-prox convoluted tubule
-Loop of Henle
-Distal convoluted tubule
-collecting duct
-urethra

4

____ of plasma is filtered into the renal tubules

20%

5

urinary output=____L/day

1.5L/day

(most fluid reabsorbed back from tubules)

6

GFR

-glomerular filtration rate
-rate of plasma filtration by glomerulus

7

Clearance

-volume from which all test substance is removed

8

______ is often used to measure GFR

-creatinine clearance

9

Creatine

-Mm metabolism byproduct
-has fairly constant plasma level

10

_________level alone is often used to monitor GFR

-plasma creatinine

11

Substantial GFR changes may be reflected in _______

-relatively small plasma creatinine changes

12

Normal Creatinine Levels

Male=0.7-1.3
Female=0.6-1.1

13

Tests of Renal System

-GFR
-Plasma Creatinine Concentration
-BUN
-Urinalysis

14

Urinalysis

-best test for infectious agents or foreign materials (toxins, drugs)
-color, turbidity, protein, pH, specific gravity, sediment)

15

Diuretics

-inhibit Na+ uptake
-->more water remains in tubule and urine

16

Diuretic Effects on Body

-decrease BP, edema, body fluid, CHF symptoms

17

Pathologies of Renal System

-Infection
-Cancer
-Renal Cystic Disease
-Renal Calculi
-Chronic Renal Failure
-Glomerulonephritis
-Neurogenic disorders
-urinary incontinence

18

UTI

-Urethritis
-Cystitis (bladder infection)

19

Urethritis Sx

-Inflamm/pain at urethral opening
-painful urination

20

Cystitis Sx

-bladder infection
-Painful urinatino
-frequent urination
-urgent need to urinate
-urine cloudy/red
-fever sometimes
-suprapubic/low back pain
-flank pain

21

Pyelonephritis Symptoms

-(Kidney infection)
-symptoms suggesting bladder infection
-abrupt onset
-high fever/chills
-back pain around kidney
-nausea/vomiting

22

Kidney/UTI Evaluation

-Urinalysis
-tender to percussion at costovertebral angle (pyelonephritis)

23

Prevention of Kidney/UTI

-post-void residual assessment to assess urinary retention
-sufficient fluid intake
-urogenital hygiene

24

Kidney/UTI Treatment

-antibiotics
-increase fluids
-consider lactobacillius acidophilus to prevent yeast growth when on antibiotics
-contact doc if not better in 48-72 hours

25

Renal Cell Carcinoma

-malignant tumor
-80-90% of all renal neoplasms

26

Renal Cell Carcinoma Incidence

-male (over 60) 2x > female

27

S/Sx Renal Cell Carcinoma

-bloody urine
-abdominal/flank pain
-palpable mass
-HTN
-hyperparathyroidism

28

Metastases of Renal Cell Carcinoma

-lungs
-bone (lumbar vert)

29

Eval/Treatment of Renal Cell Carcinoma

-radiographic imaging
-surgical removal of tumor

30

Risk Factors of Renal Cell Carcinoma

-tobacco use
-obesity
-HTN
-decreased fruits/veggies
-increased red meat
-occupational toxins
