title: [Puerperal uterine involution according to the method of delivery].
abstract: The aim of the study is to determine and estimate the absolute values of the distance between the symphysis pubis and the uterine fundus (S-FD) and the rate of uterine involution according to the method of delivery.
  
  
  METHODS
  150 women included in this prospective study are divided into 3 groups of 50 women with vaginal delivery, caesarean section and re-caesarean section. The absolute values of the distance S-FD and the rate of uterine involution were determined in cm and estimated according to their parity and the gestational age. The measurement of the S-FD was daily performed from the second day till the 5th day for the vaginal deliveries and till the 7th day for the caesarean sections.
  
  
  RESULTS
  The uterine involution in primiparous and premature vaginal deliveries starts from lower values of the S-FD than in the multiparous and in cases of term delivery. The rate of uterine involution in primiparous increases gradually in the earliest day after delivery (from 0.95 to 1.6 cm per day), while in multiparous this increasing starts after the 4th day. When caesarean section is performed and in the cases of preterm delivery the rates of uterine involution are delayed and uneven.
  
  
  CONCLUSIONS
  in cases of vaginal delivery the availability of prematurity and macrosomia of the fetus delays the rates of the uterine involution. The uterine involution after cesarean section is slower and unsteady, which is more conscious in re-sections.
