OBJECTIVE: The aim of our study is to demonstrate that intravesical administration of the association chondroitin sulfate (CS) and hyaluronic acid (HA), according to our treatment schedule, is a benefit for women with recurrent urinary tract infections (RUTI), not only from a clinical point of view, but also reducing recurrences.

METHODS: This is a study of 28 women diagnosed with RUTI, with a positive culture, and compatible symptoms; frethey underwent treatment according to the protocol of intravesical instillations of the combination CS 2%-1 gr + HA 1.6%-800 mg. To evaluate the effectiveness of the treatment, symptoms improvement, reduction of the number of episodes of urinary tract infection and quality of life were considered.

RESULTS: In our series, we can observe an improvement of the quality of life assessed by PG-I, 66% after 12 months. It was seen that 55.6% of the patient`s urine cultures became negative, while 44.4% had episodes of urinary infection, but with lower baseline symptoms intensity.

DISCUSSION: Patients included in the protocol of instillation improved significantly their quality of life; in addition, to a considerable extent new urinary infections were not presented, being milder when they presented.
