Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to study the outcome of patients after ureteroscopy in which all fragments remaining after holmium laser lithotripsy were retrieved compared to those where small, insignificant fragments were left for spontaneous passage.
