A case of extrarenal spreading of transitional cell carcinoma caused by rupture of ureterohydronephrosis by ureteral transitional cell carcinoma is reported. Ultrasonography and CT revealed the presence of a severe right ureterohydronephrosis with large septa and a 2 cm diameter exophytic neoplasia of the middle ureter. Nephroureterectomy was performed with excision of a perirenal mass. Histologic examination revealed the presence of transitional cell carcinoma in the perirenal mass, caused by dissemination after renal rupture. CT and ultrasonography were not able to differentiate hydronephrosis from pericapsular spreading because of the extreme disruption of the renal parenchyma.
报告了一例因输尿管移行细胞癌导致肾盂积水破裂而引起移行细胞癌肾外播散的病例。超声和CT显示右侧严重肾盂积水伴粗大分隔，输尿管中段有一直径2cm的外生性肿瘤。行肾输尿管切除术并切除肾周肿块。组织学检查显示肾周肿块中存在移行细胞癌，由肾破裂后播散所致。由于肾实质严重破坏，CT和超声无法区分肾盂积水和包膜外播散。
