[Painless extra-corporal shock wave lithotripsy using the HM3 Dornier lithotripter].

Area of Science:

• Urology
• Nephrology
• Medical Engineering

Background:

• Extra-corporeal Shock Wave Lithotripsy (SWL) is a common procedure for kidney stones.
• Pain management is a significant aspect of SWL, often requiring analgesics.
• Existing lithotripters may necessitate substantial perioperative medication.

Purpose of the Study:

• To evaluate the efficacy of a modified shock wave generator for the Dornier Kidney Lithotripter HM3.
• To assess the impact of the new generator on analgesic requirements during SWL.
• To determine if SWL is feasible without central acting drugs using the modified generator.

Main Methods:

• Clinical study involving the Dornier Kidney Lithotripter HM3 with a modified shock wave generator.
• Monitoring analgesic requirements, specifically Opioid-Analgesia, during the procedure.
• Observing perioperative morbidity associated with the new generator.

Main Results:

• Significant decrease in the requirement for analgesics during Opioid-Analgesia with the modified generator.
• Demonstrated feasibility of performing Extra-corporeal Shock Wave Lithotripsy without central acting drugs.
• Observed a reduction in perioperative morbidity compared to previous methods.

Conclusions:

• The modified shock wave generator for the Dornier Kidney Lithotripter HM3 enhances patient comfort by reducing pain medication needs.
• SWL can be effectively performed without central analgesics, simplifying the procedure.
• The new generator technology contributes to lower perioperative morbidity in kidney stone treatment.
