Inclusion Criteria

  1. Male or female aged ≥ 18 years to ≤ 75 years 2. Provides written informed consent 3. Patients with at least one urinary stone and up to 3 stones located proximally to the iliac vessels on one side may be enrolled. 3a. Urinary stone(s) should be apparent on a CT scan with 30 days prior to the study enrollment. 3b. Patients with at least 1 urinary stone measuring at least 6mm but not more than 20mm in diameter. For patients with multiple stones, up to 3 stones may be treated on the treated side, with a cumulative stone diameter not exceeding 20mm. All 1-3 stones are to be treated. Stone measurement will be conducted using CT imaging. 4. Patients with bilateral stones are allowed but only one side may be treated. Only the treated side will be evaluated for safety and effectiveness. 5. Patients may enter the study with a stent in place. 6. Patients presenting with absence of a Urinary Tract Infection as confirmed using urinalysis

Exclusion Criteria

  1. Patients with >3 stones on the side to be treated 2. Patients with 3 stones with a cumulative diameter >20mm on the side to be treated 3. Patients with ureteral stones located distal to the iliac vessels on the side to be treated 4. Diagnosis of radiolucent stones (on the side to be treated) on KUB or Scout CT Imaging 5. 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) 6. Patients who have had prior URS-LL within 3 months on the side to be treated at the time of consent. 7. History of cystinuria 8. Urine pH below 5.5 9. Patients with known history of recurrent uric acid stones 10. Untreated urinary tract infection (UTI) 11. History of drug-resistant chronic UTI 12. If female, pregnant as confirmed using urine test to be conducted on the day of the procedure. 13. Patient has an American Society of Anesthesiologists (ASA) physical classification level of 4 or greater. 14. 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 15. Stones suspected in calyceal diverticula 16. Horseshoe kidney 17. Congenitally ectopic pelvic kidneys 18. Full staghorn calculi >2cm 19. Patients with elevated serum creatinine > 1.5mg/dl 20. Patients with a solitary kidney 21. Malrotated kidney on the side with urinary stone 22. Duplicated collecting system or duplicated ureters 23. Patients who are currently involved in any investigational drug or device trial or have been enrolled in such trials within 30 days of index procedure 24. Patients who are actively taking antiplatelet and anti-coagulation except low dose aspirin 25. Prostate biopsy within the last 3 months 26. History of radiation therapy of abdomen and pelvis 27. History of urinary tract reconstruction 28. Other factors that the investigator feels would interfere with the participation and completion of the study such as: - Inability to provide voluntary consent - Inability to understand the clinical investigation or cooperate with investigational procedures - Planned relocation or unable to return for required follow-up visits - Vulnerable individuals (mentally disabled, physically disabled, prisoner, etc.)

Intervention Model Description
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.

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

Detailed Description

The AEROLITH Clinical Study will evaluate the safety and effectiveness of Applaud Acoustic Enhancer when used in conjunction with conventional ureteroscopic laser lithortipsy (URS-LL) in the treatment of subjects with urinary stones. The clinical study is a prospective, multicenter, two-arm, randomized, double blinded study. A total of 196 subjects will be enrolled in this study at up to 15 investigational sites located in the U.S.
