Conclusion
While choosing between fURS or srURS in patients with an upper ureteral
stone, the idea of pushing a stone that can easily be treated with
srURS to the kidney and, instead, treating it with fURS is not supported
by the findings of this study. The application of srURS after fixing an
upper ureter stone at its location using a Stone Cone®results in higher stone-free rates. For these stones, fURS and srURS
give similar results in terms of laboratory values, complication rates
and operation time. As a result, we recommend srURS supported by an
antiretropulsion method as a treatment for upper ureteral stones.
