Laser endoureterotomy with cut-to-the-light technique for complete ureteral obstruction - A case report

Abstract

Ureteral stricture and obstruction following ureteroscopy are often difficult to treat. We report successful laser endoureterotomy using the cut-to-the-light technique for complete obstruction. A 44-year-old man developed complete ureteral obstruction at the ureteropelvic junction following transurethral ureterolithotripsy. We performed laser endoureterotomy and recovered the remaining stone by an antegrade percutaneous approach, while a second surgeon illuminated the obstruction with a ureteroscope by a retrograde approach. The minimally invasive cut-to-the-light technique might be an effective alternative to conventional invasive treatments, such as pyeloplasty, ureteroureterostomy and bowel interposition, in patients with complete ureteral obstruction in whom a ureteral stent cannot be placed.
