Q

What is the detrusor muscle and why is it important?

A
  1. Located up in the wall of the bladder and remains laxed to allow the bladder to fill with urine. The muscle will contract during urination to aid in the release of urine.

Q

How does urine flow?

A
  1. Flows downward to prevent urine back flowing to kidneys
  2. Ureters connect to the bladder and have ureterovesical valves (one-way) valves that help urine not black flow into the kidneys

56
Q

What is a urostomy- aka Ileal conduit

A

It is when a portion of the ileum is resected & one end of the segment is closed; ureters are attached to closed end of ileum and open end of ileum is brough through abdomen to form a stoma; a bag is placed over the stoma

57
Q

What is a neobladder?

A

A bladder is rebuilt out of the intestine and is placed where the previous bladder was. Ureters are connected to the urethra so urine can flow through normally.

63
Q

What are some diagnostic studies for urinary systems?

A

Urinalysis
1. Measurement of color, PH, specific gravity
2. Determination of presence of glucose, protien, blood & ketones
3. Microscopic exam for crystals, bacteria

  • Use the first morning void and examine urine within 1 hour.

Urine studies
1. Urine culture and sensitivity
-(need at least 10mL of urine)
- if a UA shows bacteria, blood, positive nitrates a C&S will be done.
2. Creatinine clearance
- collect 24 hour urine specimen
- creatinine clearance closely approximates GFR (glomerular filtration rate) probably more accurate measurement of kidney function

Serum creatinine-
1.greater than 1.2 mg/dl is abnormal for women & men 1.4 mg/dL

Blood urea nitrogen (BUN) 7-20 mg/dL
1. A high BUN with normal creatinine = dehydration

64
Q

When are routine UA typically done?

A

Annual visits.

65
Q

Why is it best to collect the first void of the morning for your UA?

More concentrated and chances of bacteria in it increase

Clean with wipe before catching.
1. Make sure not to touch the inside of the cup.
2. Urinate a little before placing cup under neath stream

67
Q

What do we need to know about creatinine clearance collection?

A
  1. Discard 1st urine
  2. Collect 24 hours in large collection container placed on ice (or refrigerator if testing at home) or place urine bag over ice if they have a folley bag.
  3. Empty bladder initally; Record time; save all urine after first urine specimen discarded
  4. Collect for 24 hours
  5. have patient urinate at end of 24 hours & add to specimen collection
68
Q

What should we know about interstitial cystitis?
