How this study is set up
The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Trial stature
Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.
How this score is built
- Investigator standing0/100
No investigator recorded in the registry for this trial
These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.
Summary
The purpose of this study is to evaluate the safety and performance of the ELS to treat urinary stones. The ELS is intended to break urinary stones into small fragments that can pass during or after the procedure with less or no discomfort. Eligible patients are male or females, age 21 or older, with a single urinary stone in the ureter. Participants will undergo the ELS procedure and then be evaluated 30 days later for the presence or absence of urinary stone fragments on a CT scan. Subjects who still have stone present at Day 30 will be evaluated again at Day 60. Other outcome measures will be changes in pain, quality of life, and return to normal daily activities/work.

Arms and interventions
- The ELS Trial is a prospective, multi-center, single arm study.EXPERIMENTAL
All Subjects who qualify to participate in the ELS Trial will receive the experimental ELS procedure.
Interventions
- Device ELS (Enhanced Lithotripsy System)
ELS (Enhanced Lithotripsy System) utilizes low pressure ultrasound to actuate proprietary microbubbles administered into the urine to pit and fragment urinary stones.
Outcome measures
Primary outcome
Primary Outcome Measure
CT assessment of the target stone demonstrating either (i) stone free status (zero fragments) or (ii) the presence of only stone fragments small enough to pass spontaneously (\<=4 mm) at 30 Days post procedure.
Time frame From ELS treatment to 30 Days afterward.
