Background :The occurence of urinary tract infections (UTIs) in the course of a normal pregnancy should always be early diagnosed and treated, even asymptomatic as it could evolve to threatening pathological conditions, like sepsis with acute kidney injury, or preeclampsia. The aim of study was to establish a cartographic projection of the risk factors and etiopathogenesis of urinary tract infections diagnosed during pregnancy, with the purpose to control their severity and evaluate the therapeutic strategies used to reduce maternal and fetal risks.
Material and methods: The study included 175 patients, pregnant women, diagnosed with UTIs hospitalized in the Nephrology Clinic and Obstetrics-Gynecology Clinic of the Emergency Clinical County Hospital of Constanta, in an interval of time of 4 years, between 2017-2021.
Results: Out of the 247 patients recruited in our study, the distribution according to the trimester of pregnancy, there were : 72 pregnant women in the first trimester (41.14%), 35 in the second trimester (20.0%) and 68 in the third trimester (38.86%). The frequency of pregnant women who had other favorising conditions and detectable risk factors was 70.29%. The clinical manifestations of UTIs in our study group were distributed as follows : 36 (20.57%) asymptomatic bacteriuria, 56 (32.0%) acute cystitis, 44 (25.14%) recurrent lower urinary tract infections, and 39 (22.29%) acute pyelonephritis. There is an association (p ---lt--- 0.001) between the type of clinical form of UTIs and a certain trimester of pregnancy, for example the highest frequency of acute pyelonephritis (AP) was noticed in the third trimester of pregnancy (71.8%, 28/39). Out of 39 pregnant women with AP, 71.8% (28) had associated ureterohydronephrosis (UHN). E. Coli was present in 41.71% of pregnant women., followed by Klebsiella pneumoniae, Enterococcus faecalis and, less frequently, Staphylococcus aureus and Proteus mirabilis. The most frequently used antibiotics in pregnancy were: 2nd and 3rd generations of cephalosporins (42.29%), followed by ampicillin (34.29%); less used were amoxicillin with clavulanic acid (10.29%), quinolones (6.29%) and nitrofurantoin (6.86%). Most of the pregnant women (94.28%, 165/175) had remission of fever within 24-48 h of using appropriate antibiotic therapy. The recurrence rate was 22.28 %, (39/175).
Conclusion All clinical forms of UTIs could be present during pregnancy, but the most common are lower urinary tract infections and the most involved germ is E. Coli. UHN is a factor that influences the occurence of UTIs, being the most common favorising condition.
