Asymptomatic bacteriuria








Colony count more than 10000
No symptom
incidence 6%
25-40% Progress to pyelonephritis .
Treatment reduces this 10-fold
Ampicillin or nitrofurantoin 10-14 days
U/c one week following therapy
30% of infection recure

cystitis



.
Symptomatic bacteriuria without flank
pain or fever
Diagnosis and treatment as ASB
With sterile urine chlamydia trachomatis
suspected
pyelonephritis





.
1-3% of pregnant women
Febrile patient
,chills,urgency,dysuria,nausea,vomiting
Right sided,bilateral
Bacterial endotoxins
Macrophage cytokines
Preterm labor
Recurrent pyelonephritis



.
10-18% of patient
Nitrofurantoin 100/night
u/c every month
Treatment: 10-day course of antibiotics
Ivp 3 months postpartum
Urinary calculi


1/1000 pregnancies
Increase uti to 20-45%
Suppressive nitrofurantoin therapy
u/c monthly
Infection treated aggressively
Sonography 60%
Single view Ivp 96%(50 mrad)
with persisted obstruction ureteral stent or
percutaneous nephrostomy is required .
Chronic renal failure
Mild

Disease Decline renal
course function.
Increased
proteinuria,
Hypertention.

Accelerated
deterioration in
renal function
in 10%

Mortality 15%
Preeclampsia 50%
preterm delivery 30-80%
Growth restriction 57%
Severe
2.5
30-40% with
Decline in renal
function to end
stage dis in 12yr postpartum
Dialysis




The goal of dialysis is BUN at 5060mg/dl
Risk of fetal demise is BUN above
80mg/dl
Peritoneal dialysis is superior
for minimize fluid shift and does
not required anticoagulation
Mg-so4 can be added(serum level
5meq/l).
Renal transplantation

Avoid of pregnancy for 2 years


Complications :

.
With dose of prednisone 15 mg/day , azathioprine
2mg/kg/day
Preeclampsia
Infection (cmv,herpes,hepatitis,uti)
Parathyroid dysfunction, preterm birth
Prematurity 45-60% and 20% of this babies are IUGR
PROM
Pregnancy outcome successful 80-90%
Neurologic disorders

Tension headache

Migaine

Epilepsy

Subarachnoid hemorrhage

Pseudotumor cerebri
Migrain headache

Common, 15% first in pregnancy

R/O B.tumor,stroke,epilepsy

Menstrual migrain, 64% improvement in
pregnancy
Cerebral artery vasoconstraction

3-6 fold ischemic stroke

treatment
Aspirin , acetaminophen with or without
caffeine
 narcotics,
 Phenothiazine
 Sumatriptan succinate (Imitrex)
 Ergotamin(vasoconstrictor)
 NSAIDs should be avoided in 3th
trimester.

Epilepsy in pregnancy

No change 46%

Reduction 20%

Increase
34%
Factors that increase the
frequency of seizure
Discontinuation of medication
For belief that it harms the fetus
 Inability to ingest medication
For nausea and vomiting
 Sub therapeutic drug level
Expanding maternal vascular volume
 Lowering of the seizure threshold
By sleep deprivation and stress

druges
For many anticonvulsant drugs,the
benefit of preventing seizures
outweighs any potential risks to the
fetus
The Druges should be avoided
