Percussion Therapy for Kidney Stones
Trial Summary
What is the purpose of this trial?
Flexible ureteroscopy is characterized as first-line therapy for renal stones \< 2 cm in size. Stones are commonly treated with dusting or fragmentation techniques which requires passage of stone fragments after surgery. Quoted stone free rate after flexible ureteroscopy is approximately 40-60% with a dusting technique. Residual fragments are often under 1mm in size and can layer in the lower pole of the kidney, complicating spontaneous stone passage. Improving the stone free rate after surgery decreases the need for secondary surgeries and decreases risk of future stone events. Numerous techniques have been proposed to increase stone passage including positional changes and percussion therapy. To date, there is overall limited data a lack of techniques that can be readily available in the outpatient setting, easily added to scheduled appointments, reproducible results and well tolerated by patients.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are on blood thinners (except for low-dose aspirin up to 81mg).
What data supports the effectiveness of the treatment Massage Percussion Therapy device for kidney stones?
Is percussion therapy generally safe for humans?
How does percussion therapy for kidney stones differ from other treatments?
Percussion therapy for kidney stones is unique because it uses mechanical vibrations to help clear stone fragments after shock wave lithotripsy, which is different from traditional methods that primarily rely on breaking stones with shock waves alone. This approach may enhance the removal of stone fragments, potentially improving treatment outcomes.14111213

Eligibility Criteria
This trial is for adults who can consent and have had ureteroscopy to treat kidney stones, leaving behind tiny fragments. They must be able to undergo percussion therapy and not have conditions like osteoporosis, fluid intake restrictions, untreated UTIs, or need for secondary stone procedures soon.Inclusion Criteria
