ABSTRACT=Microbiological diagnostics is of great importance in limiting the spread of nosocomial infections. The information on etiological agents of infections and their susceptibility to antibiotics enables a quick response in the case of a suspected epidemic outbreak. The aim of this study is to analyse the incidence of nosocomial urinary tract infections among patients hospitalized in hospital wards over a period of two years and to determine the predominant etiological agent depending on the method of clinical specimen collection. Data from the Mazovian Specialist Hospital (M.S.H.) in Radom constitute the material for preparation of this study. Urine was collected using two methods. The first one was the method of collecting urine from the central stream, while the second method was urine collected from patients with a urinary catheter in place. The statistical calculations were conducted using the statistical software. Based on hospital data, it was shown that 5870 urine tests were performed during the period under review, of which 2070 were positive. The number of positive results in 2021year decreased by 2.84% compared to 2020 year. 
On the basis of statistical analysis, differences in the occurrence of multiple strains were observed between catheter-based and midstream urine collection. Differences were observed especially for Acinetobacter baumannii, Candida albicans, Escherichia coli  and Pseudomonas aeruginosa. A. baumannii, C. albicans and P. aeruginosa were significantly more frequently found in urine samples collected through the catheter than from the midstream. Furthermore, E. coli (51.56%) and E. species (25.46%) were more frequent when collected from the middle stream than when urine was collected through a catheter. However, for the strain K. pneumoniae the results were comparable when urine was collected from catheterised patients (13.83%) and from midstream (13.35%).
Urinary tract infection among hospitalized patients of the Mazovian Specialist Hospital in Radom was diagnosed quite frequently. In 2021 year, 32 more urine cultures were performed than in 2020 year. In the analysed period, among all ordered urine cultures, 35.27% of samples were positive.
