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.
