Primary renal sarcoma is a rare malignant mesenchymal tumor with a variety of histologic type. The clinical differential diagnosis with renal cell carcinoma may be impossible. The prognosis of primary renal sarcoma is extremely poor and majority of patients die within 2 years. We experienced two cases or primary renal sarcoma, which was diagnosed by immunohistochemical stains.

Uereterorenoscopy has become a useful diagnostic tool for the evaluation and treatment of the ureteral diseases such as the filling defect upper tract hematuria and abnormal cytology. Keeping a clear visual field in ureterorenoscopy is an essential for the reducing of complication such as ureteral perforation. We used alternative suction with 4 Fr. ureteral catheter through side hole of ureterorenoscopic sheath in 32 cases without serious complications. We believe that this method may help not only keeping clear visual field but also doing ureterorenoscopy safely, while use ureteral catheter as a safety guide wire.
