Abstract

OBJECTIVE: Our aim was to determine the incidence of anatomical abnormalities after a urinary tract infection (UTI) in infants <2 months of age hospitalized in the neonatal intensive care unit (NICU). STUDY DESIGN: This was a retrospective, single-center cohort study of infants <2 months of age in the NICU with a UTI and documented renal imaging. RESULT: We identified 141 infants with UTIs. The mean gestational age and birth weight were 28 weeks and 1254 g, respectively. The most commonly identified pathogen was coagulase-negative Staphylococcus (28%, 44 of 156). A major abnormality was found on at least one imaging study for 4% (5 of 118) of infants. Major abnormalities were noted on 4% (5 of 114) of renal ultrasounds and 2% (2 of 82) of voiding cystourethrography examinations. CONCLUSION: Among infants in the NICU <2 months of age at the time of a UTI, the prevalence of major anatomical abnormalities is <5%.

John Samuel Wiener

Professor of Urology

As a general pediatric urologist, Dr. Wiener is involved with all aspects of pediatric urology as a clinician and researcher.  His research interests are most focused, however, on the urologic management of neurogenic bladder and spina bifida and the molecular biology involving development of the genitourinary tract and disorders.

Dr. Wiener is the principal investigator at Duke for The National Spina Bifida Patient Registry and Urologic Management of Young Children with Spina Bifida protocol administered by the Centers for Disease Control and Prevention.  These projects began at Duke in 2011 and 2015, respectively.

Dr. Wiener was previously a project director for the P50 Center for Undiagnosed Pediatric and Urogenital Disorders.

Dr. Wiener has served in national leadership positions in pediatric urology including President of the Society of Fetal Urology, Executive Council of Society for Pediatric Urology, and the Examination Committee of the American Board of Urology.  He is currently on the Board of Directors of the Spina Bifida Association
