Q

How do you manage severe symptoms of Pyelonephritis?

Q

Why would a patient have a nephrostomy tube?

A

total obstruction of ureter

22
Q

What is a Nephrostomy Tube

A

A device surgically inserted into the renal pelvis via a small flank incision. It is attached to a external bag for closed drainage and considered temporary.

23
Q

What could excessive pain or drainage around the exit site of nephrostomy tube indicate?

A

possible blockage

24
Q

Do I need an order to irrigate Nephrostomy Tube?

A

Yes, MUST have a order from HCP.

25
Q

How much fluid can I irrigate the nephrostomy tube with?

A

No more than 5 ml of sterile NS

26
Q

How are kidney stones diagnosed?

A

Careful H&P
non contrast spiral CT (CT/KUB)- gold standard exam
Ultrasound
IVP
Urinalysis (assessing hematuria, crystalluria &ph)
Retrieval/analysis of stones

27
Q

What are the five major categories of Kidney stones?

A 
Calcium oxalate
Calcium phosphate
Uric acid
Cystine
Struvite
28
Q

How do you manage an acute attack of r/t kidney stones?

A

Treat the symptoms

  1. Pain-NSAIDS &opiods-Priority
  2. N/V
  3. Infection-systemic ABX
  4. obstruction-pass spontaneously, >4mm usually do not pass, need stent placement, removal of stones
29
Q

Kidney Stones Collaborative Care

A
  • evaluate cause of stone formation and prevent further development
  • teach patient adequate hydration & how to strain urine
  • dietary changes, depending on content of stone
    ex: Low oxalate, Low calcium( controversial because stones may not come from dietary calcium source), Low purine
30
Q

What kidney stone would require a Low purine Diet

A

Uric Acid

31
Q

What stone would require a low oxalate diet?

A

Calcium oxalate

32
Q

What is another name for pain caused by kidney stones

A

Renal colic

33
Q

what procedure is used for kidney stones

A

Lithotripsy

34
Q

explain the process of a Lithotrpsy

A 
Outpatient
Disintegrates(pulverizes) stones via shock waves
2 approach options internal(direct), external (indirect)
35
Q

what is internal (direct)

A
  • cystoscopic approach
  • percutaneous approach
  • Laser
36
Q

what is external (indirect)

A
  • stones broken down and washed out

- major advantage: not-invasive

37
Q

what are possible complications of a Lithotripsy procedure

A

Hemorrhage
infection
retention of stone fragments

38
Q

Post-Procedure, is hematuria an expected finding?

A

Yes, hematuria is common

39
Q

what would not be an expected finding after a Lithotripsy procedure

A

Decrease urine output, could indicate obstruction

40
Q

What is placed post-procedure to facilitate passage of fragments?

A

Stent and is removed after 1-2 weeks

41
Q

What are nurse implementations for kidney stones?

A
  • Patient education-lower risk factors through lifestyle and dietary changes
  • Fluid intake 3L/day with the exception of an obstructed stone FF(forced fluid) not advised, Water preferred
  • Dietary restrictions
  • Reduction of risk factors
    • sedentary/immobilized
    • adequate fluid intake
    • Turn q2
    • Stand/sit up to void bladder on regular basis
    • encourage ambulation
  • monitor passing of stones
  • control pain
42
Q

Why would the patient need a urinary diversion

A

when the patient no longer has a reservoir (bladder)

43
Q

What are the types of urinary diversions?

A

ileal conduit-incontinent diversion to skin
continent cutaneous reservoir-continent diversion to skin
orthotopic neobladder- continent diversion to urethra

44
Q

incontinent-Ileal conduit

A

Ileal conduit- urine is constantly coming out, permanent external collecting device needed

  • gold standard for urinary reconstruction before continent diversion
  • stoma visible
  • skin integrity & body image concerns
45
Q

continent-Cutaneous Diversion

A

Cutaneous diversion- must catharize stoma for urine output

  • don’t have to wear a bag because continent
  • different diversions (Indiana, Kock,Miami pouches)
46
Q

Is it an expected finding to have mucous with a Ileal conduit?

A

yes

47
Q

What is a continent- Orthotopic Neobladder?

A

orthotopic Neobladder- internal reservoirs connected to native urethra (fake bladder)
-most closely approximates normal voiding

48
Q

How is the orthotopic neobladder constructed

A

The internal reservoir is constructed from a segment of intestine (usually ileum) that is separated from bowel & anastomosed to the native urethra

49
Q

What would you do preoperatively a cystectomy?

A

address anxiety and fear
address teaching needs for post op care
include wound ostomy and continence nurse WOCN)

50
Q

What would you do postoperatively after cystectomy

A

NPO and NG to LWS for a few days to rest the gut
Patient teaching
ileal conduit: ensure properly fitting appliances & provide METICULOUS skin care
expect mucous in urine
stoma assessment
Continent diversion: cath every few hours at first, then 4-6 hrs
Neobladder: void by relaxing sphincter and bearing down ever 2-4 hrs
practice pelvic floor muscle relaxation to aid voiding

51
Q

What should the Stoma look like

A

Moist and Beefy red
