Abstract:
A 62-year-old woman underwent laparoscopic radial nephrectomy for the left renal cell carcinoma in September 2008. In July2016, the patient developed asymptomatic gross hematuria. Computed tomography (CT) revealed the enlargement of the left ureteral stump and an 11mm nodule in the superior lobe of the right lung. Since [F-18] fluoro-D-glucose-positron emission tomography-CT FDG PET-CT demonstrated a lung tumor, we decided to perform right upper lobectomybyvideo-assisted thoracoscopic surgeryin September. The patient was diagnosed with metastatic renal cell carcinoma. We then removed the left ureteral stump and performed partial cystectomy in November. A pathological examination revealed that the tumor was metastatic clear cell renal cell carcinoma invading the muscle layer. Two months later, the patient developed gross hematuria again. Cystoscopy revealed a 1cm tumor around the scar of partial cystectomy. Transurethral resection was performed, and a pathological examination revealed metastatic renal cell carcinoma. We herein report this case of renal cell carcinoma in which recurrence occurred in the ureteral stump, 8 years after radical nephrectomy.

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
