Original Article- Laparoscopy/Robotics Should We Place Ureteral Stents in Retroperitoneal Laparoscopic Ureterolithotomy?: Consideration of Surgical Techniques and Complications

Purpose: There is some debate over the necessity of ureteral stenting after laparoscopic ureterolithotomy. We evaluated the need for ureteral stenting after retroperitoneal lap-aroscopic ureterolithotomy (RLU). Materials and Methods: Between January 2009 and January 2013, 41 patients under-went RLU to remove upper ureteral stones. The retroperitoneal approach was used in all patients by a single surgeon. A double J (D-J) stent was placed in the first 17 patients after the procedure but not in any of the next 24 patients. Results: The mean patient age, serum creatinine levels, and stone size were not sig-nificantly different between the two groups. The stone-free rate was 100%. The mean operative time was significantly shorter in the stentless group than in the stent group (59.48 minutes vs. 77.88 minutes, p＜0.001). Parenteral analgesic use and anti-cholinergic medication use were observed in the stent group only. The blood loss, drain removal day, and hospital stay were not significantly different between the two groups. No other significant complications occurred during or after the operation in any patients. Conclusions: RLU is a safe and effective treatment modality for large impacted ureteral stones. In this study, D-J stent placement was not necessary after RLU. In the future, large-scale studies of RLU without D-J stenting, especially on the frequency of the de-velopment of complications according to the surgical technique, may be needed
