Miss SC was a 21-year-old G4, P0030 at 21 weeks' gestation by last menstrual period and confirmed by second-trimester ultrasound. Her pregnancy, which had been managed through a clinic, was complicated by multiple urinary tract infections and she had recently been diagnosed with pyelonephritis. The condition was treated with IV antibiotics at a community hospital and she was discharged with a prescription for ampicillin to be taken for 7 days. Miss SC said she felt well until 2 days before her second admission to the same community hospital, when she began having sharp, intermittent right upper-quadrant pain that was unrelated to eating.
