RESUMO

Background: Clean intermittent catheterization (CIC) has been a valuable tool for treating neurogenic and non-neurogenic lower urinary tract dysfunctions. Objectives: to verify the incidence of urinary tract infection (UTI) before and after instituting CIC, and identify the etiological agents. Method: this is an interventional, uncontrolled, longitudinal and prospective study performed with patients of both genders and with no age limits. Four interventions were performed during seven-month follow-up. The UTI diagnosis was defined by the presence of bacteria in a urinary culture equal or above to 105 colony forming units per milliliter, accompanied by one or more UTI signs or symptoms. Polyvinyl chloride catheters (PVC) were reused after cleaning for up to seven days and in men, was used intraurethral lydocaine 2% lubrication. CIC was recommended for one to five times a day according to the type of vesical dysfunction. Urine samples were collected by the patient or the caregiver. Results: Fifty-seven patients were enrolled, of these 30 completed the study.The median age was 30 years, ranging from five to 73 years, and 22 (73.3%) of patients were men. A total of 120 urine samples were collected for laboratory analysis. In the first evaluation, done prior to commencement of CIC, 14 (46.7%) of patients had clinically significant UTI; after initiating CIC there was a progressive reduction to a 2 (6.7%) infection rate by the fourth evaluation. The main uropathogens found were: Escherichia coli, Klebsiella Pneumoniae and Proteus Mirabilis and among these, the most frequent was Escherichia coli. Conclusions: The incidence of UTI in the studied sample was 46.7% and CIC reduced the occurrence of UTI in 85.7%. The most frequent etiologic agent was Escherichia coli. The present study results suggest that intermittent catheterization with the clean technique, reusing the (PVC) catheter, is safe
