Background/Aims/Objectives: Women with recurrent urinary tract infections (UTIs) are commonly referred to urology outpatient clinics. However, there is no clear consensus in existing guidelines as to if, or how, these should be investigated. The primary outcome was to evaluate all available literature to determine the percentage of abnormal findings in non-pregnant women with recurrent simple UTIs. Secondary outcomes were to determine the percentage that were serious, consequential or incidental findings. Methods: A full literature search was performed of the following databases: MEDLINE; Pubmed; Cochrane Central Register of Controlled Trials-CENTRAL; and ClinicalTrials.gov. Two assessors reviewed the articles independently. Any discrepancy was discussed and an agreement reached. Results: The literature search yielded 662 titles; 652 were excluded on initial review. A further 13 studies were gathered from references of yielded papers. After full review, 12 were included for analysis. These showed that < 1.5% of women investigated for recurrent simple UTIs with imaging or flexible cystoscopy had life-threatening pathology, but up to 67% had abnormal urodynamics. Conclusions: Women presenting with simple recurrent UTIs should have a flow rate and post-void residual measured. Cystoscopy is not warranted and imaging is unlikely to be of value in the absence of symptoms of upper tract disease or gynaecological problems.
