16
Q

elderly and UTI

A

usually none of the normal sx, but with delirium

17
Q

treatment of UTI

A

antimicrobial therapy
increased fluid intake
avoid bladder irritants
cranberry capsules have been shown to reduce risk in those with chronic infection

18
Q

acute pyelonephritis is an acute infection of the ____, ___ ____ and/ or ___ ___

A

ureter
renal pelvis
renal parenchyma

19
Q

manifestations of pyelonephritis

A

rapid onset of fever
chills
malaise
flank pain

20
Q

treatment of acute pyelonephritis

A

antibiotics

generally resolves in 10-14 days

21
Q

chronic pyelonephritis

A

persistant or recurring episodes of acute pyelonephritis

22
Q

people with ___ ____ and some type of ____ pathological condition are at risk for chronic pyelonephritis

A

renal infections

obstruction

23
Q

chronic pyelonephritis can lead to

A

loss of tubular function
ability to concentrate urine
this leads to polyuria, nocturia, proteniuria and maybe eventual end stage renal failure

24
Q

Glomerulonephritis

A
  • presence of anti- steptococcal antibodies:
    1. formation of antigen- antibody complex
    2. activates complement system
    3. inflammatory response in glomeruli causing leakage of some protein and RBC
  • severe inflammatory response
    1. congestion and cell proliferation; decreased GFR leading to retention of fluids and wastes
25
Q

CM of Glomerulonephritis

A
urine is dark and cloudy 
facial and per-orbital edema 
elevated BP
flank back pain
general signs of inflammation 
decreased urine output
26
Q

dx of Glomerulonephritis

A

blood tests
metabolic acidosis
urinalysis

27
Q

blood tests for Glomerulonephritis

A
  • elevated serum urea and creatinine
  • elevated anti-DNase B, streptococcal antibodies, anti- spteptolysin, anti- streptokinase
  • decreased complement levels (used in renal inflammation)
28
Q

urinalysis of Glomerulonephritis

A

proteniuria
hematuria
erythrocyte casts
no evidence of infection

29
Q

tx of Glomerulonephritis

A

sodium restriction
protien and fluide intake decreased
drug treatment like glucorticoids and anti-hypertensives

30
Q

polysystic kidney disease

A

growth of fluid filled cysts BILATERALLY in kidneys , resulting in replacement of functional tissue, reduced profusion, tubule obstruction

31
Q

PKD categories

A

Genetic, autosomal dominant
Genetic, autosomal recessive
Acquired

32
Q

CM of PKD

A
Enlarged kidneys
Hypertension
Flank pain
Altered fluid, electrolyte balance
Renal calculi- Diverticular disease
Urinary tract infection
Liver, pancreatic cysts
Cardiac valvular disease
Cerebral aneurysms
33
Q

PKD dx

A
Family history
Genetic testing
Physical exam
Hypertension
Imaging studies	
Presence of > 3 kidney cysts on ultrasound
Extrarenal cysts
Laboratory confirmation of renal failure
34
Q

PKD treatment

A

Symptomatic care

  • Pain control
  • Treatment of infection
  • Blood pressure control

Promotion of renal function

  • Dialysis
  • Renal transplant
  • Supportive care during end-stage renal disease
