The results showed that ESWL before the RIRS did not complicate the
surgery but significantly increased the peroperative fluoroscopy time.
The duration between the last ESWL session to the RIRS was a predictor
for stone free-rates. The number of ESWL sessions before the RIRS was a
predictor of operation time. According to our knowledge this article is
the first article documenting the effect of pre-RIRS ESWL on the
efficacy and safety of RIRS.
