Abstract: Eosinophilic cystitis is a rare inflammatory disease of the bladder whose origin, pathogenesis, and treatment are unknown. Frequency, dysuria, and hematuria are frequent symptoms. Here, we report a rare occurrence of recurrent urinary retention and repetitive catheterization. A 67-year-old male presented with acute urinary retention and intermittent gross hematuria of 2 weeks duration. Urethral catheterization followed by a trial without catheter, was successful. Complete blood count showed presence of eosinophils (eosinophilia) and computed tomography of kidneys, ureter and bladder with contrast showed thickened bladder wall and small prostate. Cystoscopy revealed an erythematous lesion over the anterior wall. The rest of the mucosa was normal. Transurethral biopsies of the lesion were performed and histologic examination showed features of eosinophilic cystitis. Despite multiple medication regimens containing corticosteroids and antihistamines, he presented with recurrent urinary retention, approximately once every month. After 6 months, he was started on bethanechol, which led to no catheterization for up to 2 years. To the best of our knowledge, this is the first report on the successful use of bethanechol as a treatment for eosinophilic cystitis with recurrent urinary retention.
