NCT07272720

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Stone-free rate (SFR)

    Proportion of subjects who are stone free or present with clinically insignificant residual fragments (measuring ≤ 4 mm on CT)

    6±2 weeks post 1st treatment

Other Outcomes (16)

  • Stone free rate (SFR)

    12±4 weeks post 1st treatment

  • Stone free rate

    12±1 months post 1st treatment

  • Proportions of subjects with stone-free status classified into grades

    6±2 weeks post 1st treatment

  • +13 more other outcomes

Study Arms (2)

ESWL with kidney stone tracking (StorM-Track).

EXPERIMENTAL
Device: ESWL with kidney stone tracking (StorM-Track)

Standard ESWL without stone tracking (StorM-Track disabled).

ACTIVE COMPARATOR
Device: Standard ESWL without stone tracking (StorM-Track disabled)

Interventions

ESWL with kidney stone tracking (StorM-Track)DEVICE

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.

ESWL with kidney stone tracking (StorM-Track).
Standard ESWL without stone tracking (StorM-Track disabled)DEVICE

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

Standard ESWL without stone tracking (StorM-Track disabled).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

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

You may not qualify if:

  • BMI \> 34.9
  • Target stone that cannot be localised
  • Presence of one or more additional stones \> 4 mm in the target kidney
  • Presence of one or more additional stones ≤ 4 mm located in the same calyx (upper, mid, or lower pole) or in the renal pelvis as the target stone
  • 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
  • +9 more criteria
