PMCF Investigation of MODULITH® SLX-F2 With StorM-Track in Patients With Kidney Stones

Post-Market Clinical Follow-Up Investigation of MODULITH® SLX-F2 With StorM-Track in Patients With Kidney Stones - A Confirmatory Parallel-Group, Randomized Controlled Trial


Sponsor

Storz Medical AG

Enrollment

126 participants

Start Date

Dec 11, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

Extracorporeal shockwave lithotripsy (ESWL) is a non-invasive standard treatment for kidney stones. This study will be conducted to evaluate the effectiveness of ESWL using MODULITH® SLX-F2 with stone tracking, compared to MODULITH® SLX-F2 without stone tracking, in adult patients with kidney stones, as measured by stone-free status.


Eligibility

Min Age: 18 Years

Inclusion Criteria3

  • Age ≥ 18 years
  • Single kidney stone (6 - 15 mm) in the target kidney
  • Stone density assessed by Hounsfield unit value (HU) ≤ 1,200 HU

Exclusion Criteria23

  • BMI \> 29.9
  • Target stone that cannot be localised
  • Multiple kidney stones in the target kidney
  • Stones with a density value of \> 1,200 HU
  • Skin to stone distance (SSD) \> 160 mm
  • The presence of obstructions, malformations or other factors preventing targeting or passing of the stone, including but not limited to the following:
  • Skeletal malformations and obesity, preventing targeting of the stone
  • Malignant tumour in the shockwave path
  • Arterial aneurysm or calcium deposits, or thrombosis in shockwave path
  • Brain, spinal column or air-filled tissue, especially the lungs, in the shockwave path
  • Obstruction distal to the stone (as this would hinder the passage of fragments through collecting system or ureter)
  • Any disease/medical condition, prior or concomitant medication/treatment/intervention, or implant that may affect this clinical investigation, and/or is contraindicated for the IMD, including but not limited to the following:
  • Severe nephrocalcinosis
  • Uncontrolled urinary tract infection
  • Coagulation disorders and bleeding diathesis, not compensated according to urological and hemostaseological guidelines
  • Anticoagulation or platelet inhibition therapy, not bridged according to urological and hemostaseological guidelines
  • Uncontrolled hypertension
  • Blood pressure \> 180/100
  • Active cardiac implants that are not authorized for use with ESWL
  • Pancreatitis
  • Ehlers-Danlos syndrome
  • Administration of contrast agents containing gases for ultrasound diagnostics less than 24 hours before treatment.
  • Pregnancy

Interventions

DEVICEESWL with kidney stone tracking (StorM-Track)

Starting ESWL on a low energy setting with stepwise ramping and at a frequency of 1.0 or 1.5 Hz. Up to a maximum of 3'500 shockwaves unless there is no stone visible in X-ray imaging. If fragments \> 4mm remain after the first ESWL treatment, a 2nd ESWL will be performed.

DEVICEStandard ESWL without stone tracking (StorM-Track disabled)

Same treatment protocol as for the intervention group. If fragments \> 4mm remain after the first ESWL treatment, a 2nd ESWL will be performed.
