title: A case of bladder cancer after radiation therapy for prostate cancer.
abstract: An 86-year-old male who presented with the chief complaint of clot retention and had a history of prostate cancer treated with external beam radiation therapy 11 years previously is described. Cystoscopy revealed radiation cystitis in coexistence with bladder cancer. Since bladder cancer may be present in patients with macroscopic hematuria who have a history of radiation therapy, referral to an urologist is recommended.
