Cut-to-the-light technique and potassium titanyl phosphate laser ureterotomy for complete ureteral obstruction.
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.
