Introduction:

Laparoscopic ureterolithotomy is used for large ureteral stones when endoscopic methods fail. This study aimed to assess its safety and identify predictors of complications.

Material and methods:

We retrospectively analyzed 40 patients who underwent laparoscopic ureterolithotomy from 2005 to 2023. Data included demographics, stone features, surgical details, and outcomes.

Results:

All patients achieved stone-free status with no conversions or transfusions. The average hospital stay was 4.6 days. Severe postoperative pain was the most common complication. Prior percutaneous nephrostomy and postoperative fever were linked to prolonged hospitalization. Retroperitoneal approach and history of acute kidney injury were associated with greater analgesic use. No long-term complications were reported.
