Fecal microbiota transplantation in a kidney transplant recipient with recurrent urinary tract infection.

PURPOSE: We report on a kidney transplant recipient treated with fecal microbiota transplantation (FMT) for recurrent urinary tract infections. METHODS: FMT was administered via frozen capsulized microbiota. Before and after FMT, urinary, fecal and vaginal microbiota compositions were analyzed. RESULTS: The patient remained without symptoms after FMT. CONCLUSIONS: Underlying mechanisms of action need to be addressed in depth by future research.
