    IC/BPS: One-fourth of patients have Hunner lesions

    Cystoscopy recommended in patients over age 50 and men, researcher advises

    Boston—About one-fourth of patients with interstitial cystitis/bladder pain syndrome (IC/BPS) have Hunner lesions in the bladder visible on cystoscopy.

    Their urologic symptoms are indistinguishable from those of patients without Hunner lesions, according to H. Henry Lai, MD, and colleagues.

    In addition, “IC patients with Hunner lesions may be less likely to have certain systemic manifestations, such as irritable bowel syndrome and anxiety,” said Dr. Lai, associate professor of surgery and anesthesiology, Washington University, St Louis. He presented his data at the AUA annual meeting in Boston.

    The rate of Hunner lesions found is substantially higher than that reported in the literature.

    “We probably have a selected group of patient for which Hunner lesions may be enriched,” Dr. Lai told Urology Times. “I think generally the experience is that about 10% of patients may have Hunner lesions, based on some of the published studies from the U.S. and Canada.”

    Since patients with Hunner lesions respond to specific treatments (such as triamcinolone injection, fulguration, or cyclosporine) and because Hunner lesions may represent a distinct phenotype among patients with IC/BPS patients, “one should consider cystoscopy to look for Hunner lesions, particularly for patients over the age of 50 or in men,” he said.

    The authors hypothesized that IC/BPS patients with Hunner lesions may represent a different phenotype from patients without Hunner lesions. For their study, they compared urologic symptoms (urgency, frequency, nocturia, urologic pain, bladder hypersensitivity, and sexual dysfunction) and nonurologic features (severity and distribution of systemic pain, comorbid functional pain syndromes, anxiety, and depression) between patients with and those without Hunner lesions visible on office cystoscopy without hydrodistention.

    All patients completed a battery of questionnaires in which urologic features were assessed, such as the Interstitial Cystitis Symptom and Problem Indexes (ICSI, ICPI), Pelvic Pain and Urgency/Frequency Questionnaire, numeric ratings (0 to 10) of pain, urgency, and frequency, RICE Questionnaire, and the AUA Symptom Index. Nonurologic measures included the Hospital Anxiety and Depression Scale (HADS), psychologic stress, the Body Pain Map, Brief Pain Inventory, Poly-Symptomatic Poly-Syndromic Questionnaire, and comorbid pain conditions (irritable bowel syndrome [IBS], fibromyalgia, and chronic fatigue syndrome).

    A Hunner lesion was defined as “a circumspect, reddened mucosal area that can have vessels radiating toward a central scar and/or a fibrin deposit of coagulum attached to this area.” It often bleeds (like a waterfall) with bladder distention.
