Prospective study feasibility: Screening of antenatal total abnormal pulmonary venous return.

Introduction: Total abnormal pulmonary venous return is a heart defect often missed prenatally, yet at birth, it is a surgical emergency. Antenatal detection could be improved by sonographic visualization of the anastomosis of 2 pulmonary veins in a sinus into the left atrium. The objective of this study is to evaluate the feasibility of this screening method.

Posterior urethral valves and vesicoureteral reflux: can prenatal ultrasonography distinguish between these two conditions in male fetuses?

Objective: The objective of the study was to evaluate prenatal sonographic signs that distinguish male fetuses with posterior urethral valves (PUV) from those with vesicoureteral reflux (VUR).

Methods: Prenatal data were retrospectively retrieved from all consecutive women delivering between 2003 and 2012 of a male newborn with a postnatal diagnosis of PUV or VUR. Prenatal parameters included fetal bladder characteristics, identification of a dilated posterior urethra, and change in shape and size in the fetal renal pelvis or ureter.

Conservative management of placenta accreta: hysteroscopic resection of retained tissues.

Study Objective: To evaluate the feasibility and the results of hysteroscopic removal of tissue after conservative management of retained placenta accreta.

Design: Retrospective study (Canadian Task Force classification II-3).

Setting: Tertiary care university hospital.
