Inclusion criteria

  • Pregnant women who seek prenatal care within the University of Texas Health System with UT Physicians.
  • Urine culture of less than 100,000 CFU

Exclusion criteria

Exclusion Criteria:

  • Less than 18 years of age
  • Risk factors to complicated UTI (including but not limited to: diverticula, urolithiasis, renal cysts, indwelling catheter, intermittent catheterization, stent placements, nephrostomy tubes, neurogenic bladder, cystocele, vesicoureteral reflux, ileal conduit)
  • Use of drugs
  • Abnormalities of the urinary tract (including but not limited to: known ureteric or urethral strictures, tumors of the urinary tract, pelvicalyceal obstruction, congenital anomalies, history of urological procedures)
  • History of renal disease including renal failure and transplants
  • Urine culture > 100,000 CFU of any organism
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Study arms

  • Active comparator
    Antibiotic treatment

    Standard prenatal care with treatment for any urine culture with growth of 1- 100,000 CFU of any organism.

    Drug: Antibiotic · Other: Standard Prenatal Care

  • Active comparator
    No antibiotic treatment

    Standard prenatal care without treatment for any urine culture with growth of 1- 100,000 CFU of any organism.

    Other: Standard Prenatal Care

Interventions

  • DrugAntibiotic

    Those randomized for treatment will be prescribed the most commonly used antibiotic for urinary tract infections in pregnancy. This includes: Nitrofurantoin, Cephalexin, and Amoxicillin. It is unsure which antibiotic the participant will receive but a majority of the time it will be one of the above named antibiotic. The choice will be determined by the physician, but will accommodate participants' prior medication history and adverse events.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 3, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
