A colovesical fistula is a pathological communication between the colon and bladder. The symptoms include pneumaturia, fecaluria, and a lower urinary tract infection. The diagnosis is based on clinical symptoms, but the symptoms are not specific. Therefore, confirming the diagnosis is challenging. Urine cultures performed in patients with colovesical fistulas usually show growth of or mixed growth of bowel organisms. Urinary tract infections caused by are very rare, as it is rarely considered pathogenic in humans. We report the case of a 70-year-old woman who presented with symptoms of a recurrent urinary tract infection. Urine cultures were positive for . Abdominopelvic computed tomography (CT) revealed focal thickening of the bladder wall and gas in the bladder. Cystoscopic examination and colonoscopy revealed sigmoid colon cancer and a sigmoido-vesical fistula. Laparoscopic surgical treatment was done. The patient recovered and was discharged 3 weeks later without chemoradiotherapy. On follow-up after 6 months, the patient was asymptomatic and stable. To our knowledge, this is the second reported case of infection of the urinary tract and the first reported case in adults. infection usually indicates the presence of serious underlying diseases such as malignancies, uncontrolled diabetes, and organ failure.
结肠膀胱瘘是结肠与膀胱之间的病理性通道。症状包括气尿、粪尿和下尿路感染。诊断基于临床症状，但这些症状并不具有特异性。因此，确诊具有挑战性。结肠膀胱瘘患者进行的尿培养通常显示肠道细菌生长或混合生长。由[具体细菌名称未给出]引起的尿路感染非常罕见，因为它在人类中很少被认为是致病的。我们报告了一例70岁女性患者，她表现出复发性尿路感染的症状。尿培养结果显示[具体细菌名称未给出]呈阳性。腹盆腔计算机断层扫描（CT）显示膀胱壁局灶性增厚以及膀胱内有气体。膀胱镜检查和结肠镜检查发现乙状结肠癌和乙状结肠膀胱瘘。进行了腹腔镜手术治疗。患者康复，3周后未接受放化疗出院。6个月后的随访中，患者无症状且病情稳定。据我们所知，这是第二例报道的[具体细菌名称未给出]引起的尿路感染病例，也是首例成人病例报道。[具体细菌名称未给出]感染通常表明存在严重的基础疾病，如恶性肿瘤、未控制的糖尿病和器官衰竭。
