Melissa Mulholland had no idea the baby she was carrying might not survive. If she hadn't gone to a high-risk clinic for an ultrasound, and if that ultrasound hadn't been reviewed by a doctor with expertise in a certain area of fetal care, the outcome could have been much different. Her ultrasound showed a fetal abnormality called posterior urethral valves (PUV), a congenital problem that is sometimes missed in reviews of ultrasounds unless doctors are trained to look for it, which they generally are not. PUV, which affects 1 in 8,000 males, means that extra tissue obstructs the baby's bladder, causing a reverse flow of urine that can damage other organs, and can be fatal. At 16 weeks, Mulholland, director of business strategy for One Commercial Partner (OCP), which helps enable Microsoft partners' success around the world, underwent a risky procedure.
