title: Falsely elevated postvoid residual urine in pregnant women.
abstract: Portable ultrasound assessment of postmicturition bladder for residual urine volume is rapid, accurate, and precise. However, other cystic pelvic pathologic conditions may present as a false-positive finding on the ultrasound. We describe two cases in which the residual urine was falsely detected as being elevated due to unsuspected pregnancy.
