[Temporal and bacteriological comparison of neonatal urinary infections].
OBJECTIVE
To find out the epidemiological and management changes of urinary tract infection over the last years.


METHODS
Descriptive retrospective review of patients with urinary tract infections (UTIs) admitted to our neonatal unit over an 11 year period. A temporal, microorganism group and voiding cystourethrography (VCUG) group comparison.


RESULTS
We studied 106 cases (5 cases/1,000 alive newborns). The most commonly isolated microorganisms were Escherichia coli (81.1%), Enterococcus faecalis (6.6%) and Enterobacter cloacae (4.7%). Gentamicin had an overall sensitivity of 93.2%, followed by cefotaxime 91.3% and amoxicillin-clavulanic acid 89.5%. We did not found temporal differences in microorganisms or sensitivities. We found differences in C reactive protein, nitrate and leucocyte values in E. coli versus non-E. coli UTIs, as well as patterns of antibiotic sensitivity with more resistances by non-E. coli microorganisms. No differences were found in patients with normal and pathological VCUG. We found ultrasound and VCGU disturbances in 35.2% and 21.4%, respectively.


CONCLUSIONS
UTI is a common problem in our area. The most frequently isolated microorganism is E. coli. Non-E. coli UTIs have more resistances to usual therapies, although these did not show any increase in disease in the imaging tests. We found no increase in resistances throughout the study.
