Interventions

  • Surgery — PROCEDURE
    Upfront surgery is the planned removal of asymptomatic stones and includes ureteroscopy and shockwave lithotripsy, which are routinely used in standard clinical care.
  • Observation — OTHER
    Observation is the surveillance of asymptomatic stones with periodic CT, ultrasound, or x-ray, and clinic visits.

Study Details

The aims of the Observational Approach versus Surgical Intervention for Asymptomatic Stone (OASIS) trial are: 1) to determine whether observation compared to upfront surgery results in less healthcare-related life disruption due to kidney stones among children and adults with asymptomatic kidney stones; 2) to identify the groups benefiting the most from each strategy; and 3) to determine the preferences and values informing the choice between observation and upfront surgery.
