Thus, an accurate non\u2010invasive diagnostic method is necessary. The objective of this study is to determine the efficacy of transvaginal bladder ultrasound (TBU) for CT diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Between 2012 and 2021, 114 women (17\u201376\u2009years old) with recurrent urinary tract infection (RUTI) and history of antibiotic resistance were evaluated with TBU by a single ultrasonographer. As a control group, TBU was performed in 25 age\u2010matched women with no previous history of UTI, urological or gynecological conditions. All patients with RUTI had undergone a cystoscopy with biopsy for diagnostic confirmation at the time of trigone cauterization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thickening of trigone mucosa (&gt;3\u2009mm) was detected in all patients with RUTI and represented the most relevant criteria for trigonitis diagnosis on TBU. Other TBU findings in CT are: irregular and interrupted mucosa lining (96.4%), free debris in the urine (85.9%), increased blood flow at doppler (81.5%), mucosa shedding and tissue flaps. Biopsy showed CT with erosive pattern (58%) or non\u2010keratinizing metaplasia (42%). Diagnostic agreement index between TBU and cystoscopy was 100%. In the control group, normal trigone mucosa is ultrasonographically regular, continuous, with thickness \u22643\u2009mm and there is no debris in the urine.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>TBU proved to be an efficient, inexpensive and minimally invasive method to diagnose CT.
