Conclusion:
In kidney stones larger than 2 cm, the most important parameter
determining the benefit of the UAS and general infective complications
in terms of infective process is the operation time. While the risk of
infection increases when the operation time exceeds 60 minutes, FURS can
be safely performed up to 87.5 minutes in terms of infection risk, with
89% sensitivity and 69% specificity.
