Case report discusses surgical intervention for upper tract urothelial carcinoma in crossed fused renal ectopia, suggesting effective treatment options.
Upper tract urothelial carcinoma in conjunction with congenital renal malformations is exceedingly rare in clinical practice, presenting significant challenges for surgical intervention. We detail a case involving crossed fused renal ectopia accompanied by upper tract urothelial carcinoma. Computed tomography urography imaging revealed abnormalities in the ureteropelvic region. Subsequent urinary cytology, ureteroscopy and pathological analysis confirmed the presence of urothelial carcinoma. A radical laparoscopic nephroureterectomy was conducted, and postoperative pathology indicated a low-grade urothelial carcinoma. No tumor recurrence or metastasis was observed during one-year postoperative follow-up. Our clinical validation confirms laparoscopic surgery as a safe and efficacious therapeutic modality.
