Urinoma mimicking pancreatic pseudocyst: Case report

Abstract

Introduction. A urinoma is a localized urine collection in the retroperitoneum, occurring outside the urinary tract. Although relatively rare, traumatic urinomas in pediatric patients pose significant diagnostic and therapeutic challenges. Initial diagnosis primarily relies on ultrasonography, but computed tomography (CT) and magnetic resonance imaging (MRI) provide clearer differentiation and localization. The treatment strategy focuses on preventing potential complications and promoting urinary tract recovery. Case Report. We present the case of a seventeen-year-old male with a penetrating abdominal injury. Prompt abdominal exploration revealed and managed minor colon and spleen lacerations. Upon readmission due to the fever and abdominal pain, further diagnostics initially misinterpreted the formed traumatic urinoma as a pancreatic pseudocyst. Postoperative computed tomography, cystoscopy, and retrograde pyelography subsequently confirmed the existence of a urinoma. Conclusion. Through this case report and its atypical manifestation, we aim to highlight the importance of differential diagnosis, the complexity of abdominal injuries, and diagnostic and treatment protocols in pediatric populations. Emphasizing a multidisciplinary strategy is crucial to optimizing treatment outcomes.
