Inserting a Metallic Ureteral Stent Using an Antegrade Approach Freed a Patient from Nephrostomy Created due to Hydronephrosis Caused by Bladder Cancer

For the treatment of internal ureteral orifice invasion of bladder cancer, percutaneous nephrostomy is usually attempted initially. However, percutaneous nephrostomy reduces patients' quality of day life. A 65-year-old man showed bilateral hydronephrosis due to locally advanced bladder cancer, and right percutaneous nephrostomy was created. After dilating the percutaneous nephrostomy, we inserted a metallic ureteral stent via an antegrade approach. We herein report a case of metallic ureteral stent insertion via an antegrade approach after initial creation of a nephrostomy, thus freeing the patient from nephrostomy.
