Those satisfying the criteria for urinary tract infection were selected for detailed analysis. Demographic, clinical and laboratory data were collected using a pre-coded questionnaire. Common presenting features included fever (32%), poor feeding (30%) and irritability (22%). Los infantes que presentaron cultivos bacterianos positivos, fueron identificados usando los registros de laboratorio. The preterm neonatal rates have been noted to be higher than that for term neonates and may be as high as 10% with an inverse relation to the birthweight (4, 5). Data from South African studies show prevalence rates for UTI of up to 26% in hospitalized infants and children and 17% in community-based studies (6, 7). The vague, non-specific presentation of this disease makes it likely for clinicians to miss the diagnosis unless routine urine cultures are done in the sick infant.
Failure to diagnose will result in delay in institution of appropriate therapy and an increase in the already high propensity for scar formation noted in infancy.
In appreciation of these challenges, The American Academy of Paediatrics published recommendations for diagnosis, treatment and evaluation of initial UTI in febrile infants and young children.
Tamim et al in analyzing the efficacy of urine culture as part of sepsis evaluation in the neonate reported that there was minimal benefit in obtaining cultures from very low birthweight infants in the first 24 hours of life but emphasized that it was important to obtain urine cultures from older patients with signs of sepsis (5).
Other differences in the epidemiology of this condition may well exist for developing countries making it unwise to adopt recommendations that are based on epidemiological and clinical patterns of this disease in developed countries. There is a need to describe the local and regional patterns of this infection before any consensus recommendations can be made for investigation and management of UTI in Caribbean neonates.
This study seeks to describe the epidemiology of UTI in neonates admitted to the University Hospital of the West Indies (UHWI).


The neonatal unit is a 30-bed unit and serves primarily the needs of the sick neonate delivered at the UHWI. Urinary tract infection was defined as the growth of a significant number of colonies per ml on agar plated with a sample of urine. The distribution of culture -positivity amongst neonates admitted to the newborn unit for presumed sepsis is shown in Fig. These revealed unilateral renal agenesis with hydronephrotic contralateral kidney in one case and solitary kidney in the other case. Vesico-ureteric reflux (VUR), a recognized risk factor for UTI has been reported in 18 to 40% of infants investigated after a first episode of UTI (4).
There appears to be ethnic differences in prevalence rates of VUR, with lower rates described in persons of African ancestry as compared to Caucasians (11, 12).
This however, was a small study and a separate incidence rate was not calculated for children being worked-up solely for UTI.
Of course, not all infants with reflux disease would necessarily present with a UTI in the neonatal period. The necessity of MCUG studies in the work-up of the Jamaican infant with UTI has been questioned, given documented low rates of VUR by West et al. Ultrasonographic abnormalities resulting from reflux while frequent in severe disease may be entirely absent in mild reflux. In the present study, abdominal ultrasonography alone would have missed one case of reflux amongst those investigated, which translates to 2.5% of infants screened with ultrasound alone.
Miller (unpublished data) found ultrasound to be sensitive in detecting Grade 4 and 5 VUR but ultrasound did not detect most cases of Grade 3 and all cases of grade 1 and 2 VUR.
In that series, 88% of cases with documented VUR on MCUG had normal ultra-sonographic study.


The consequences of missing infants with underlying VUR or posterior urethral valves, in a country like Jamaica, where there is limited availability of dialysis and renal transplant are far reaching.
The absence of laboratory evidence of haematological responses to serious bacterial infection in most of the study patients with UTI further supports this discrepancy in our setting. The absence of useful clinical and laboratory markers that indicate the likelihood of UTI in neonates emphasize the important role of urine cultures in sepsis evaluations as the only reliable means of identifying disease.
In addition, the study provides support for continuing the practice of renal tract imaging on all neonates with UTI.
