Chemical (urine-induced) peritonitis is a rare but potentially life-threatening complication in patients with advanced bladder cancer. It may result from sterile urinary leakage into the peritoneal cavity, typically through microscopic wall disruption or tumor necrosis. This condition can mimic perforation or bacterial peritonitis, posing a significant diagnostic challenge. We describe the case of a 78-year-old male with de novo high-grade urothelial carcinoma, presenting with persistent gross hematuria, bilateral hydronephrosis, and severe anemia. Despite initial tumor resection and nephrostomy placement, the patient's condition deteriorated with signs of peritoneal irritation and systemic inflammation. Emergency cystoprostatectomy revealed extensive tumor necrosis and inflammatory peritoneal fluid, but no macroscopic bladder perforation. Histopathology confirmed muscle-invasive high-grade urothelial carcinoma (pT2b) with necrosis and angioinvasion. This report illustrates a diagnostic and therapeutic challenge in the management of advanced bladder cancer complicated by suspected sterile chemical peritonitis, emphasizing the importance of early source control in critically ill patients.
化学性(尿液诱发的)腹膜炎是晚期膀胱癌患者中一种罕见但可能危及生命的并发症。它可能源于无菌性尿液漏入腹腔,通常是通过微小的膀胱壁破裂或肿瘤坏死。这种情况可类似穿孔或细菌性腹膜炎,带来重大的诊断挑战。我们描述了一名78岁男性患者的病例,该患者患有新发高级别尿路上皮癌,表现为持续性肉眼血尿、双侧肾积水和严重贫血。尽管最初进行了肿瘤切除和肾造瘘术,但患者病情恶化,出现了腹膜刺激征和全身炎症表现。急诊膀胱前列腺切除术显示广泛的肿瘤坏死和炎性腹腔积液,但未见肉眼可见的膀胱穿孔。组织病理学证实为肌层浸润性高级别尿路上皮癌(pT2b)伴坏死和血管侵犯。本报告说明了在疑似无菌性化学性腹膜炎并发的晚期膀胱癌管理中的诊断和治疗挑战,强调了在危重症患者中早期源头控制的重要性。
