What are the reasons in gynae surgery for manual removal of placenta?

Manual removal of the placenta in gynecological surgery is typically performed to address complications such as retained placenta, which can lead to excessive bleeding and infection. It is often necessary when the placenta fails to detach naturally after delivery, particularly in cases of placenta accreta or when the uterine tone is poor. The procedure allows for direct intervention to ensure complete removal, thereby reducing the risk of postpartum hemorrhage and promoting better recovery for the patient. Additionally, it can be essential in managing cases where uterine contractions are insufficient to expel the placenta naturally.
