Flashcards in Maternal Physio - Urinary Deck (12):
1

Serum creatinine and creatinine clearance in pregnancy

  • Serum creatinine
    • Decreased
  • Creatinine clearance
    • Increased by about 30%

 

Summary:

  • The clearance is increased so the actual crea is decreased

2

Is glucosuria abnormal in UA?

May not be abnormal

3

Is proteinuria abnormal during pregnancy?

Yes

4

Probable cause of hematuria

Often a result of contamination during collection

5

Changes in the ureters and mechanism

Dilate due to compression from uterus at the pelvic brim and the effect of progesterone

6

Dilation of right versus left ureter and rationale

R > L due to the dextroversion of the uterus

7

Effect of dilated ureters

Dilated ureters cause ↑ glomerular size and ↑ fluid flow → enlarged kidneys

8

Why pregnant women are at risk to asymptomatic bacteriuria and pyelonephritis

Decreased ureteral peristalsis and increased ureteral compression cause urinary stasis

9

Right hydronephrosis in pregnancy

----

Normal or abnormal?

Normal

10

Bladder anatomical changes

  • Trigone
  • Size and tortuosity of vessels

  • Trigone
    • Bladder trigone is elevated
  • Size and tortuosity of vessels
    • Increase in size and tortuosity

11

Is continence maintained in pregnancy?

Yes

  • bladder pressure increases at term but
  • Intraurethral pressure increases as well

12

Why is the bladder susceptible to trauma and infection

Increased preseure from pressenting part

Impaired drainage of blood and lymph from bladder base
