Double-J stent insertion has been generally performed during laparoscopic upper urinary tract (UUT) surgery to prevent transient urinary tract obstruction and postoperative flank pain due to ureteral edema and blood clots. However, several restrictive conditions that make this procedure difficult and time consuming include the coiled distal ends of the flexible double-J stent and the limited bending angle of the laparoscopic instruments. To overcome these limitations, we devised a double-J stenting method using the new J-tube technique. Between July 2011 and May 2013, double-J stents were inserted using the J-tube technique in 33 patients who underwent laparoscopic UUT surgery by a single surgeon. The mean stenting time was 4.8 ± 2.7 min, and there were no intraoperative complications. In conclusion, the J-tube technique is a safe and time-saving method for double-J stent insertion during laparoscopic surgery.
