Laparoscopic ureterolithotomy for large proximal ureteric stones: Surgical technique, outcomes and literature review.

For treatment of large ureteric stones, our study showed that LPU achieves 100% stone-free status. When performed by well-trained laparoscopic surgeons, it is safe and has no major perioperative complications. According to our results and literature data, when counseling patients with large impacted proximal ureteral stones, LPU should be advised as the procedure that has the higher SFR, lower auxiliary treatments, and comparable complication rates to other treatments.
