Abstract
Ultrasonography was performed using the full-bladder technique in 58 patients with intrauterine gestations. Post-voiding scans were then obtained to assess changes in placental position and to determine the optimal window for amniocentesis. Twenty-two of the 41 patients with gestations between 13-21 wk and 4 of the 17 with gestations between 24-34 wk had changes in placental position after voiding, presumably due to the effect of the distended bladder on uterine position. These findings should be considered when using ultrasound to locate a suitable window for amniocentesis.
