The placement of the flexible ureteroscopic sheath during lithotripsy may injure the ureter. We have developed a double-tube flexible ureteral access sheath. Thirteen patients with renal calculi were treated with double-tube and flexible sheath in one stage. CT examination of 13 cases showed that the ureter was normal. The double-tube flexible ureteral access sheath makes the operation of sheathing easy, safe and effective.
