We describe a case of complete ureteral obstruction managed by endoscopic recanalization using a ‘cut‐to‐the‐light’ technique followed by potassium titanyl phosphate (KTP) laser ureterotomy. A 53‐year‐old man developed a ureteral obstruction following the transurethral resection of a bladder tumor (TUR‐Bt) at the left ureteral orifice. The length of the obstructed segment was estimated at 1 cm based on combined antegrade and retrograde contrast studies. Histopathological analysis indicated that the obstruction was caused by fibrosis. The ‘cut‐to‐the‐light’ technique was used for recanalization, and KTP laser ureterotomy was performed to obtain an adequate ureteral lumen. A 14 F/7 F endoureterotomy stent was removed 6 weeks after the operation. No significant complications and no signs of stenosis were observed 24 months after endoscopic repair. Endoscopic recanalization is a safe, effective technique for the management of a completely obliterated ureteral segment, especially in combination with subsequent KTP laser ureterotomy.
