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 determine how soon ureteral stents can be safely removed following surgery.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The rationale for this study is to determine if there is a difference in symptoms or complications among patients undergoing uncomplicated ureteroscopy for stone removal with shorter indwelling stent duration. Currently there are only a few small studies exploring the optimal duration of stent placement after stent placement and no multicenter randomized control trials. The investigation aim is to determine if earlier ureteral stent removal will reduce urinary symptoms after stent removal and improve quality of life without increasing risk of negative side effects. Using questionnaires for stent related symptoms the researchers will assess stent indwelling time effect on patient reported side effects.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria
