Nephroureterectomy is considered the reference standard treatment for invasive transitional cell carcinoma of the ureter. When this malignancy occurs in a patient with renal fusion anomaly, separating the involved kidney from its conjoint mate becomes a challenging task for the surgeon. We report a unique case in which a patient with an L-shaped left-to-right crossed ectopic kidney was diagnosed with invasive ureteral transitional cell carcinoma. The preoperative assessment in these uncommon cases should include renal angiography or computed tomography angiography to provide key information about the renal vasculature, which is essential for planning the surgical dissection and line of separation between the kidneys.
肾输尿管切除术被认为是输尿管浸润性移行细胞癌的参考标准治疗方法。当这种恶性肿瘤发生在患有肾脏融合异常的患者身上时，将受累肾脏与其相连的同伴分离对外科医生来说是一项具有挑战性的任务。我们报告了一例独特的病例，一名患有从左到右L形交叉异位肾的患者被诊断为浸润性输尿管移行细胞癌。在这些罕见病例中，术前评估应包括肾血管造影或计算机断层扫描血管造影，以提供有关肾血管系统的关键信息，这对于规划手术解剖和肾脏之间的分离线至关重要。
