[Is diabetes a risk factor of urinary tract infection in patients with ureteral obstruction? Results of a retrospective study].

The goal of this retrospective study is to assess if diabetic patients are more likely to develop urinary tract infection (UTI) within the context of ureteral obstruction. 804 patients that had received an emergency treatment by double J placement for ureteral stone were selected between January 2004 and December 2014 at the Clinique Saint Pierre d'Ottignies, Ottignies-Louvain-La-Neuve,Belgium. They were divided in two groups : patients with UTI associated and the control group with the non infected ones. In the group of infected patients, 82 were diabetic whereas they were 46 in the control group. There was a significant difference regarding the presence of diabetes between the group of patients with UTI and the control group (p inferior to 0.001). This study demonstrates that diabetic patients are at higher risk of urinary tract infection in case of ureteral obstruction, thus an invasive treatment could be considered faster.
