How to insert a double J stent in laparoscopic retroperitoneal dismembered pyeloplasty: a new technique.

Antegrade placement of double J stent during laparoscopic pyeloplasty is technically demanding and time consuming, especially when operating in the retroperitoneal space. We report a new, time-saving method to antegrade insertion of a double J stent that we use in retroperitoneal laparoscopic dismembered pyeloplasty. This technique employs the recovery of a guidewire introduced retrograde through an open tip ureteral catheter placed in the mid-ureter at the beginning of the procedure and brought into the sterile area. The guidewire issued through a laparoscopic port will be used in the antegrade insertion of the double J stent. We used this technique in 6 consecutive retroperitoneal laparoscopic dismembered pyeloplasties. The stent was correctly placed in all 6 cases in less than 5 minutes without any difficulty. This is a simple and straightforward technique.
