Figure 1: 1A: we used a 7-Fr × 26-cm D-J stent and two metal guidewires to fabricate our modified D-J stent system. 1B & 1C: designed for middle ureteral stone. 1D & 1E and 1F & 1G: designed for upper ureteral stone

Figure 2: 2A: Ureteral stone was removed. 2B: The metal stents was kept outside the abdomen after pushing D-J stent into peritoneal cavity
Figure 3: Schematic diagram of a modified D-J stent being introduced into the ureter with antegrade and retrograde technique via the ureteral incision hole using laparoscopic forceps.
3A: insertion of one end of the D-J stent with a metal guidewire into the renal pelvis using laparoscopic forceps. 3B: pull out the metal guidewire and the placement D-J stent within renal pelvis. 3C: insertion of the other end of the modified D-J stent with a guidewire into the bladder using laparoscopic forceps. 3D: pull out the metal guidewire and the placement D-J stent within bladder, then adjustment of the location of the D-J stent in the ureter
