Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be done by a computer program. Randomisation will be performed by a research nurse not providing care to the patient. Allocation concealment will done by providing the treatment in concealed containers. Doctors providing care for the patients are not involved in the treatment administration.

Summary
Brief summary
The aim of this study is to evaluate the effectiveness of microdox bladder rinse in patients with recurrent UTIs. Efficacy will be assessed by the number of symptomatic UTI’s during the 3 month treatment period and 3 months following completion of Microdox. Women must meet criteria for recurrent UTI i.e. > 2 documented symptomatic UTIs in preceding 12 months. We are aiming to exclude catheterised women.
This is a multi-centre, double blinded, randomised trial. Intravesical Microdox treatment is superior to intravesical normal saline wash for the prevention of recurrent UTI’s at 6 months. There is currently no human trials using Microdox in the bladder. Most research on Microdox is based on wound care. There is one recent randomized trial using normal saline wash in catheterised patients and the UTI rate decreased markedly. The cost and suffering resulting from Recurrent UTI’s is significant. Hence better treatments of Recurrent UTI’s is desperately needed, particularly treatment that won’t contribute to the growing antibiotic resistance, and we are hoping that Microdox could be the answer.
