The primary outcome measure was relapse, defined as stone growth, an urgent or emergent medical visit, or operation for the randomized stones of interest within 14 months of the procedure. These events would include visits caused by the treatment and the presence of residual stones. Relapse data from untreated control groups with small stones or fragments from three published contemporaneous studies with similar protocols and 1- to 5-year follow-up were pooled and inverse probability weighted for comparison. The cumulative incidence of relapse was estimated using the Kaplan\u2013Meier method.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Between April 2023 and September 2024, 18 participants underwent treatment of 27 asymptomatic small stones; 7 (39%) participants underwent a second BWL procedure to complete treatment.
