Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Absence of or Have Residual Fragments Measuring Less </= to 2 mm

    Study subjects who present with a complete absence of stones, or have residual fragments measuring less than or equal to 2 mm on the treatment side, as assessed by CT imaging

    At 30 days post index procedure

Study Arms (2)

Ureteroscopic Laser Lithotripsy with Acoustic Enhancer

EXPERIMENTAL

Ureteroscopic Laser Lithotripsy with Acoustic Enhancer

Device: Ureteroscopy Laser Lithotripsy (URS-LL) with Acoustic Enhancer

Standard Ureteroscopic Laser Lithotripsy

ACTIVE COMPARATOR

Standard Ureteroscopic Laser Lithotripsy

Device: Standard Ureteroscopic Laser Lithotripsy

Interventions

Applaud's Acoustic Enhancer is provided in a lyophilized form. After reconstitution, it is a liquid, containing micron-scale particles that are made of a perfluoroalkane gas core with a lipid shell. The device is intended to be used with cleared/approved pulsed laser systems in fragmenting urinary stones (calculi) in the upper (superior) pole, lower (inferior) pole, and interpolar region of the kidney, pelvis of the kidney, and proximal ureter.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female aged ≥ 18 years to ≤ 75 years
  • Provides written informed consent
  • Patients with at least one urinary stone measuring 6mm or greater (but no more than a cumulative diameter of 20mm) located proximally to the iliac vessels on one side may be treated.
  • Urinary stone(s) should be apparent on a CT scan within 60 days prior to study enrollment. Stone assessment will be conducted using CT imaging following CLIN-0025: AEROLITH IDE Study Screening Guide.
  • Patients with bilateral stones are allowed but only one side may be treated. Only the treated side will be evaluated for safety and effectiveness
  • Patients may enter the study with a stent in place.
  • Patients presenting with absence of a Urinary Tract Infection as confirmed using urinalysis

You may not qualify if:

  • Patients with stones exceeding a cumulative diameter of 20mm on the side to be treated. Note: Punctate stones measuring ≤ 2mm do not count in the cumulative diameter limit.
  • Patients with ureteral stones located distal to the iliac vessels on the side to be treated
  • Diagnosis of radiolucent stones (on the side to be treated) on KUB or Scout CT Imaging
  • For patients who have a ureteral stent in place, patient is excluded if stent is calcified or encrusted as verified using standard of care imaging (e.g. KUB X-ray)
  • Patients who have had prior URS-LL within 3 months on the side to be treated at the time of consent.
  • History of cystinuria
  • Urine pH is \< 5.5.
  • Patients with known history of recurrent uric acid stones
  • Untreated urinary tract infection (UTI)
  • History of drug-resistant chronic UTI
  • If female, pregnant as confirmed using urine test to be conducted on the day of the procedure.
  • Patient has an American Society of Anesthesiologists (ASA) physical classification level of 4 or greater.
  • Known sensitivity to possible medications used before, during, or after the URS Laser Lithotripsy procedure, including but not limited to the following: sedative agents, general anesthetics, topical anesthetics, and opioid analgesics
  • Stones suspected in calyceal diverticula
  • Horseshoe kidney
  • +16 more criteria

Model Details: This study is a double blinded study in which study subjects will not be informed of their treatment allocation through the index procedure. In assessing stone fragmentation using a CT image as defined in the primary endpoint, an independent radiologist will conduct the assessment and will be blinded to the treatment allocation of each subject's CT image.
