Urinary tract infections (UTI) are common bacterial infections in children. This study aimed to examine the relationships between different microorganisms and both clinical and laboratory findings in pediatric patients with UTIs. We conducted a retrospective evaluation of children with UTI between 2019 and 2024. Patients were divided into four main groups as normal anatomy, vesicoureteral reflux (VUR), ureteropelvic junction obstruction (UPJO), and neurogenic bladder (NB). Information on clean intermittent catheterization (CIC) and prophylactic antibiotic use was recorded. Laboratory results were compared across these patient groups. The study included 266 patients, with a female predominance (female/male ratio: 7.33). NB was the most common urinary tract condition (43.3%), followed by VUR (10.9%) and UPJO (9%). Prophylactic antibiotics were used by 9% of the patients. Acute phase reactants in patients with CIC were significantly higher (p=0.023 for white blood cell (WBC) and p=0.002 for C-reactive protein (CRP) levels). They were also higher in patients with prophylactic antibiotics compared to those without (p=0.001 for both). The most frequently detected bacteria in urine cultures were E. coli (65%), followed by Klebsiella spp. (18.8%), Pseudomonas spp. (7.5%), and Proteus spp. (4.9%). Klebsiella spp., Enterococcus spp., and Morganella spp. were not isolated from patients receiving prophylaxis (p=0.022). Risk factors for UTIs need to be carefully assessed for every patient, and treatment should be customized according to clinical and laboratory results. Individual patient factors should guide drug selection, and treatment plans should account for potential resistance patterns.
