title: [Perinatal complications in patients with chronic renal insufficiency on hemodialysis].
abstract: BACKGROUND
  Pregnant patients with chronic renal insufficiency treated with hemodialysis experience adverse perinatal results.
  
  
  OBJECTIVE
  To compare perinatal complications of patients with chronic renal insufficiency undergoing hemodialysis who become pregnant vs. the complications of women with chronic renal insufficiency not undergoing dialysis but who then require dialysis during gestation.
  
  
  METHODS
  Transversal and retrospective study that included three patients with chronic renal insufficiency on chronic hemodialysis who became pregnant (group A) and three patients with chronic renal insufficiency without hemodialysis at the time of conception but who required dialysis during gestation (group B). Perinatal results were compared. Statistical analysis was performed with measures of central tendency and dispersion and Student t-test.
  
  
  RESULTS
  Group A had 25 sessions vs. group B with 29 hemodialysis sessions (p = 0.88). Maternal complications were anemia 100% (six cases), Cesarean delivery 83.3% (group A 2 cases vs. group B 2 cases), preeclampsia 50% (group A 2 cases vs. group B 1 case), uncontrolled hypertension 50% (group A 2 cases vs. group B 1 case), preterm delivery 50% (group A 2 cases vs. group B 1 case), transfusion 33.3% (group A 2 cases), polyhydramnios 33.3% (group A 1 case vs. group B 1 case) and abortion 16.6% (group A 1 case). Fetal complications included fetal loss 16.6% (group A 1 case), neonatal mortality 33.3% (group A 1 cases vs. group B 1 case), prematurity 50% (group A2 cases vs. group B 1 case), fetal distress 50% (group A 1 case vs. group B 2 cases), respiratory failure 33.3% (group A 2 cases) and fetal growth restriction 16.6% (group A 1 case).
  
  
  CONCLUSIONS
  Frequency of perinatal complications is elevated in both groups.
