Abstract
Background: Clinical effectiveness and safety of the Swiss Lithoclast (Lithoclast) and the Candela MDL-2000 (MDL) in the treatment of lower ureteral stone were examined retrospectively.
Methods: Eighty-six stones from 66 patients and 26 stones from 20 patients were treated by Lithoclast and MDL, respectively.
Results: The stone-free rate on 3-month follow-up was 97% and 95% for the Lithoclast and MDL, respectively (no significant difference). The operation time was significantly shorter for the Lithoclast than for the MDL (90.2 ± 50.2 vs 120.4 ± 55.1 min; P < 0.05). Postoperative analgesics were required significantly less frequently in Lithoclast (10/66 vs 11/20; P < 0.01). Postoperative hospital stay was significantly shorter for Lithoclast (8.7 ± 5.1 vs 12.1 ± 4.2 days; P < 0.01).
Conclusions: Swiss Lithoclast is an effective and less invasive modality for endoscopic treatment of lower ureteral stones.
