尽管不常见，结肠膀胱瘘会造成显著的发病率，很多病人需要等待数月才能得到正确的诊断和治疗。大多数病例出现在年长的男性身上，他们可能患有憩室病、克罗恩病、癌症或医源性损伤，这些疾病可能发生在患者的远古时代，不太容易被察觉。由于老年病人患憩室炎的发病率不断增加，同时更多的病人接受膀胱插管治疗，我们需要在评估任何有尿路感染症状的病人时怀疑这种诊断，特别是男性患者在常规治疗无效的情况下症状持续时间较长。版权所有 © 2023 The Cleveland Clinic Foundation。保留所有权利。

Although uncommon, colovesical fistula creates significant morbidity, and many patients wait months to receive a correct diagnosis and treatment. Most cases are in older men who have diverticular disease, Crohn disease, cancer, or iatrogenic injury, and some of these associations may have occurred in the patient's distant past and may not be immediately apparent. Since the incidence of diverticulitis in elderly patients is increasing and, in a separate trend, more patients are undergoing bladder instrumentation, we need to suspect this diagnosis when evaluating any patient with urinary tract infection, especially a man with prolonged symptoms refractory to conventional treatments.Copyright © 2023 The Cleveland Clinic Foundation.
