Preterm premature rupture of membranes and abruptio placentae: is there an association between these pregnancy complications?

Article Abstract:

Women with preterm rupture of membranes are at increased risk for placental abruptions. A placental abruption is when some or all of the placenta detaches from the uterine wall before birth. The incidence of placental abruption was compared between 756 women with ruptured membranes between 20 and 36 weeks gestation who were undergoing expectant management and 11,240 women who did not have preterm membrane rupture. Among women with preterm rupture, the incidence of placental abruption was 5% versus 0.9% among control group women. Most women with placental abruption experienced vaginal bleeding either before or after membrane rupture. Forty-six percent of women with preterm membrane rupture experienced fetal distress during labor compared with 7% of the control group. Possible explanations for the association between preterm rupture and placental abruption include uterine decompression with the loss of amniotic fluid, a disorder of blood flow in the placenta, or the setting in of infection.

Massive hydronephrosis mimicking theca lutein cysts in association with partial hydatidiform mole

Article Abstract:

A pregnant 15-year old girl developed hydronephrosis in association with a hydatidiform mole. Hydronephrosis is distention of the kidney caused by obstruction of the ureter, the tube that carries urine from the kidney to the bladder. The patient had developed abdominal pain and uterine bleeding. Spontaneous vaginal passage of a large mass had occurred soon after the development of symptoms. She was admitted to the hospital after she went three months without a menstrual period. A pregnancy test had been positive one day before admission to the hospital. Ultrasonography revealed multiple cysts in her right abdominal cavity. These cysts were thought to be theca lutein cysts, a type of cyst that occurs in pregnant women. Her symptoms continued despite complete removal of the tissue. A physical examination and ultrasonography revealed that she was suffering from hydronephrosis in association with a hydatidiform mole.
