RESUMO
BACKGROUND: The incidence of urinary complications in transplantation is 2% to 20%, which can be decreased with the use of a double-J catheter. The objective of this study was to determine the association between the use of the catheter and the probability of urinary tract infection (UTI). METHODS: We studied a retrospective cohort of 1038 patients divided into 2 groups: those treated with vs without a double-J catheter. Perioperative factors related to catheter use were analyzed. Second, whether the use of the catheter was associated with fewer other urinary complications was analyzed. RESULTS: Of the whole sample, 72 patients were eliminated from the study, and 358 (37%) received a double-J catheter. UTIs occurred in 190 patients (19.6%), of whom a greater proportion received a catheter: 88 of 358 (24.6%) vs 102 of 608 (16.8%) (odds ratio, 1.61; 95% confidence interval, 1.17-2.22; P = .003). CONCLUSIONS: The placement of a double-J catheter during transplant is associated with a higher proportion of UTIs, increasing their severity and the cost of care, without having a clear effect on other types of urinary complications.
