Aim: To summarize a new and easy technique of double-J stent (DJ stent) placement after retroperitoneal laparoscopic ureterolithotomy (RLU). Materials and Methods: RLU for upper and upper half of mid ureteric stones was performed successfully in 172 patients during the 8-year period between March 2011 and February 2019. In all the cases, a ureteric DJ stent was successfully placed by this new technique. A small-bore antral puncture needle is inserted into the retroperitoneal space to push down a DJ stent with a guidewire into the lower ureter. The tip of the antral puncture needle is manipulated to bring it near the ureterotomy site for easy insertion of the stent. The whole stent is pushed down leaving only the upper end in the ureterotomy area. Then, the guidewire is removed and the upper end is pushed up slowly into the renal pelvis. Results: DJ stents were successfully inserted by this technique in all the 172 cases. In most cases, the stent could be placed in <3 min (range between 2 and 8 min). In two patients, the upper end failed to fully coil in the renal pelvis, but as the stent was passed beyond the ureterotomy site, it served its purpose of an internal drain. None of our cases had any urinary leak. Stents were removed cystoscopically after 6–12 weeks. Conclusion: This technique provides an easy, fast, and safe antegrade method of inserting a DJ stent after RLU.
