We demonstrate the successful conservative management of a ureteral tumor in a horseshoe kidney.
A patient with low grade transitional cell carcinoma of the left lower ureter had asymptomatic horseshoe kidney. Biopsy specimen revealed low grade tumor in the lower urinary tract that was associated with a congenital abnormality. The patient underwent total ureterectomy with bladder cuff excision and ileal ureteral interposition.
With this technique renal function was preserved without resection through the isthmus of the kidney. The patient has no evidence of recurrent disease after 20-month followup by cytology, computerized tomography, excretory urogram and cystoscopy.
Organ preserving surgery is an alternative to total nephroureterectomy in lower ureteral tumors in select patients.
我们展示了马蹄肾输尿管肿瘤成功的保守治疗。
一名左输尿管下段低级别移行细胞癌患者伴有无症状马蹄肾。活检标本显示下尿路存在低级别肿瘤且与先天性异常相关。患者接受了输尿管全切术加膀胱袖状切除术及回肠代输尿管术。
通过该技术，肾功能得以保留，未通过肾峡部进行切除。经细胞学、计算机断层扫描、排泄性尿路造影和膀胱镜检查，该患者在20个月的随访后无疾病复发迹象。
对于特定患者的下段输尿管肿瘤，保留器官手术是全肾输尿管切除术的一种替代方案。
