Introduction: Renal cell carcinoma is the 3rd most frequent malignity of the urogenital tract in adults. If it is diagnosed early, the prognosis is very good-with 5-year survival of about 91 % up to 100 %, in the 1st clinical stage. Material and methods: Authors present a case of a 60-year-old man with renal cell carcinoma (RCC), after nephrectomy, with a rapid rise of renal insufficiency caused by subrenal obstruction of the solitary kidney. Ureteral metastasis of renal cell carcinoma (RCC) was revealed revealed as the rare cause of this acute case. Only 50 cases of this type of RCC metastasis have been found in literature up to now. Results: 2.5 years after nephrectomy we decided for ureteral endoprotesis (JJ stent) to improve patient’s condition. After some further examinations surgery revision with ureterotomy and extirpation of ureteral tumor was carried out. The histological conclusion was metastasis of renal cell carcinoma. After radiotherapy the patient is in our uro-oncological observation. Conclusion: Authors want to describe very rare cause of acute condition of a patient after nephrectomy for tumor.
