[Risk of recurrence of retained placenta].
OBJECTIVE
To calculate the risk of recurrence of retained placenta (RP) and to investigate predisposing factors for recurrence.


METHODS
Retrospective.


METHODS
Ikazia Hospital Rotterdam, the Netherlands.


METHODS
Childbirths of all patients who delivered between 1986 and 1989 and who had a RP were investigated and analysed.


RESULTS
A total of 134 patients with RP were included in the study. 17 of 75 patients who had given birth before had a recurrence of RP (23%). 17 of 53 patients (32%) who had a successive pregnancy had a recurrence of RP. Three of five patients with placenta accreta, had RP at the next delivery. Four patients who delivered after two successive RPs all had a third RP.


CONCLUSIONS
The recurrence of RP was high: 32%. Placenta accreta and a history of multiple RPs appear to predispose to recurrence.
