Material and Method
A total of 176 consecutive patients treated with RIRS for kidney stones
were included in the study. Patients were divided into two groups, group
1 receiving the standard of care (n=51) and group 2 receiving
second-look flexible URS (n=125). In all cases, one or more calyceal
stones of 1 to 4 mm were extracted with a basket at the time of stent
removal. Unless earlier intervention was necessary, patients were
followed up every six months to determine if they had experienced SREs.
