Objective: Urinary tract infection (UTI) often causes different clinical presentations ranging from asymptomatic bacteriuria which do not require treatment, to urosepsis requiring hospitalization in the intensive care unit. UTIs may lead to treatment failure, recurrence of infections or increased morbidity and mortality in the presence of complicating risk factors. The aim of this study was to evaluate the risk factors for the development of recurrent UTI (RUTI) in adults.

Methods: The records of 136 patients who were hospitalized with the diagnosis of UTI between January 2016 and December 2017 were retrospectively reviewed, and patients with recurrence after treatment were included in the study. The diagnosis of UTI, time between two admissions, risk factors, microorganisms grown in cultures and duration of treatment were examined.

Results: Of the 136 patients included in the study, 23 (16.9%) had RUTIs, and 12 (52.1%) of the RUTIs were caused by a pathogen with multidrug resistance. Most common organisms isolated in urine cultures were Escherichia coli in 18 (78.3%) patients and Pseudomonas aeruginosa in 3 (13%) patients. Male gender, ages 65 and older, being home care patient, clean intermittent catheterization (CIC) use, presence of residual urine (>100 ml), presence of spinal cord injury, presence of indwelling Foley catheter (>4 weeks), neurogenic disorder of lower urinary tract and history of extracorporeal shock wave lithotripsy (ESWL) were determined as statistically significant risk factors.

Conclusions: Unnecessary Foley catheter application, which is one of the risk factors that may cause RUTIs, should be avoided. In addition, we think that further studies are needed for actions to be taken to prevent UTIs that may occur in the presence of pathologic processes such as spinal cord damage and residual urine diminishing urinary flow, and due to applications such as CIC and ESWL.
