Q

risk factors for renal calculi

A

-gender
-race
geographic location
seasonal factors
dec fluid intake
high protein intake , high na intake, alot of sugar, corn syrup, grapefruit, apple juice
family hx
if you get your first one before 25 chances inc a lot to get another one

Q

patho of renal stones

A

-supersaturation of one or more stone
basically higher amounts of salts then there is water to dissolve them
so salt percipiated into a solid mass
aggregation makes it bigger also

Q

risk factors for UTI

A

-urinary stasis
-people are immobile
-urinary retention from meds like beta blockers
-benign prostate hyperplasia is obstruction the urethra
-urinary stone lead to obstruction of urine
-CATHETERS ARE THE NUMBER ONE REASON
-fistulas expose the urinary stream to skin or vagina to GI tract
-sex
-immunocompromised
-constiatpation
neurological disorders that make it hard for PT to pee

Q

cystitis

2 types explain each

Study These Flashcards
A
  • inflammation of the bladder
  • UTI causes this
  • could be caused by trauma, autoimmune disease or meds but usually caused by the growth of bacteria, virus or fungus which is infectious cystitis the other ones are noninfectious
22
Q

where can a UTI occur

Study These Flashcards
A

in the kidneys or the bladder anywhere the urinary system

23
Q

manifestations of a UTI

Study These Flashcards
A
  • LUTS- low urinary tract symptoms
  • lower abdominal or supra-pubic pain
  • urgency to pee
  • dysuria
  • frequency inc
24
Q

what are the manifestations of UTI in older people

Study These Flashcards
A
  • they usually don’t have the LUTS they get delirious- confused and agitated
25
treatment for a UTI
- drink alot of water - antimicrobial meds - avoid bladder irritants like caffeine - cranberry juice is really good for preventing but so has constant hydration
26
pyelonephritis
- upper urinary tract infection could be acute or chronic
27
actue pyelonephritis - what areas can it impact - what does it usually begin as?
- infection of the ureter, renal pelvis, renal parenchyma | - usually begins as a bacterial infection that spread up the urethra or traveled through the blood tot he kidney
28
manifestations of acute pyelonephritis
- rapid onset of fever - chills - flank pain - malaise
29
treatment for acute pyelonephritis
-antibiotics for 10-14 days
30
what organisms can cause acute pyelonephritis
- E.coli | - Hospital Acquired Infection - colform bacteria but could also be because of the resistent klebsiella and pseudomonas
31
chronic pyelonephritis
-persistent or occurrent episodes of acute pyelonephritis
32
in what group of people does risk for chronic pyelonephritis inc
- individuals who have renal infections | - obstructive condition
33
what can chronic pyelonephritis lead to?
- loss of tubular function and the loss of the ability to concentrate urine - poluria - protienuria - nocturia - end stage renal failure in 10 %
34
Glomeruli
-filtering uint of the kidneys
35
glomerulonephritis GN
- several diseases of the kidney that usually impact both of them - one of the leading causes of end stage kidney disease
36
what do the many of the glomerulonephritis present as?
- inflammation of the glomeruli or of the small blood vessels in the kidneys - but some do not have the inflammation - they have a collection of immune complexes in the glomeruli made up of antigens and antibodies - the antigens can be part of the normal kidney tissue or something dissolved in the blood or body fluid - viruses and bacteria are also antigens - exposure to bacteria, viruses, drugs or toxins can trigger the glomerular injury
37
some autoimmune diseases that trigger GN
-lupus and diabetic nephropathy
38
GN causes what | 4things
-serve inflammatory response which leads to a dec functioning of the kidneys causes retention of wastes -dec GFR -cell proliferation congestion in the kidney
39
how is GN classified
extent of damage that was done | initial cause of the the damage- scleroderma, lupus, strepp
40
In GN describe the steps leading to the disease
- presence of anti-strep antibodies - formation of the antibody-antigen complex - complement is activated - glomeruli have an inflammatory response leading to the accumulation of antigen and antibody and compliment - increases the capillary permeability so there is leakage of some large protein and RBC into the urine
41
Acute GN happens after what? | Who is it more common in?
men | after a strep oral infection
42
when do symptoms appear for acute GN
-10 days after the infection began
43
Clinical Manifestations of GN
-dark and cloudy urine bc blood and protein are passing through it -high blood pressure bc inc renin secretion and dec GFR -flank or back pain - bc of edema and stretchig of renal capsule -facial and preorbital edema then general edema -general signs of inflammation dec urine output
44
diagnostic tests for GN
``` -blood tests high serum urea and creatinine bc the kidneys aren't removing it well strep antibodies -will have metabolic acidosis -urinalysis- check for blood (will have it, rusty urine), protein, in urine, inc BUN dec GFR no evidence of infection ```
45
treatments of GN
-steroids LIKE GLUCOCORDITIDS to reduce inflammation -high BP meds dec protein, Na and water intake bc they are retaining these things already
46
Polycystic Kidney Disease
- life threatening genetic disorder -usually starts in one kidney and progresses to both -growth of fluid filled cysts on the kidney which causes enlargement of the kidneys functional tissue is replaced reduced perfusion of the kidneys tubule obstruction
47
in serve cases of PKD what gets damaged?
-the liver, pancreas via pancreatic cysts and the heart and brain cerbral aneurysms
48
two forms of PKD
``` determined by the way they are inherited Autosomonal dominant Autosomonal recessive (less common) ```
49
clinical manifestations of PKD
``` enlarged kidneys usually both HTN Flank pain bc of the enlarged kidneys altered fluid and electrolyte imbalances renal calculi UTI ```
50
diagnosing PKD
-family history -genetic testing -physical exam- HTN, Ultrasound or CT to see the cyst LABS- GFR, BUN, creatinine
51
treatments for PKD
control the symptoms like pain, treat infections, control BP | promotion of renal function- dialysis 3-4 hours a week, renal transplant
