The size of the outer diameter of the fURS can affect the safety, efficacy, and medical costs of the treatment. Particularly for children, their ureters are thinner and more tortuous compared to adults, which places higher demands on medical devices. The investigators are interested in determining if the performance of the two different sizes of fURS (6.3 Fr vs. 8.6 Fr) are equivalent.
