Management of Fragments During Ureteroscopy

Should we Strive for Absolute "Stone Freedom" While Performing Holmium Laser Lithotripsy for Ureteral Stones? A Randomized Controlled Trial.

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.

Inclusion Criteria:

• Patient with ureteral stones suitable for endoscopic treatment

Exclusion Criteria:

• presence of ipsilateral kidney stones
• known ureteral stricture
• previous placement of ureteral stent
• use of drugs with known activity on smooth ureteral muscle
