Trigonitis is usually asymptomatic. It can sometimes present with urinary frequency, urgency, and pain. Unlike keratinizing squamous metaplasia, it is not a premalignant lesion. While its name suggests inflammation, it is more accurately described as a result of chronic irritation. Infection and indwelling catheters may predispose a patient to trigonitis. It most often occurs in premenopausal women.
Asymptomatic patients do not require treatment. A number of treatments are being used experimentally in patients with symptomatic trigonitis: antibiotics, sodium hyaluronate installation, and endoscopic laser treatment.
