V06-10: Robot-assisted nephroureterectomy with inferior vena cava thrombectomy for poorly differentiated variant of urothelial carcinoma of right kidney

Video

INTRODUCTION

Urothelial carcinoma of the renal pelvis with renal vein and inferior vena cava (IVC) tumor thrombus is extremely rare.

METHODS

We report a 58-year-old female who suffered from left chest pain initially. Gross hematuria developed later. Abdominal CT and renal MRI disclosed diffusely infiltrating right renal tumor with right renal vein and level II IVC thrombus. Chest CT revealed a left lung tumor then the pathology report of the lung biopsy disclosed metastatic urothelial carcinoma. We performed robot-assisted palliative nephroureterectomy with bladder cuff excision and IVC thrombectomy.

RESULTS

The peri- and postoperative periods were uneventful. The final pathology was poorly differentiated variant of urothelial carcinoma which invaded the renal parenchyma, renal vein and IVC.

CONCLUSION

We would like to share this unusual variant of urothelial carcinoma with even rare IVC tumor thrombus and the feasibility with safety of robotic IVC thrombectomy.
