Summary

Proper selection of ureteral stent length might help in reducing comorbidities associated with ureteral stenting, currently there is no standardized way of measuring ureteral length. Measurement of ureteral length according to Computed Tomography (CT) scan might provide useful information when selecting the length of a ureteral stent. Our aim in this study is to compare ureteral measurements using CT scan and measurement of actual ureteral length measured during ureteral stenting.

Conditions

• Ureteral Calculi
• Hydronephrosis
• Ureteral Obstruction

Interventions

Type	Name	Description
DEVICE	Ureteral catheterization - Cook Urological Inc. open end ureteral catheter 5FR	During a planned procedure involving ureteroscopy or ureteral stenting, after retrograde pyelography and insertion of a safety wire, ureteral catheterization will be performed using Cook Urological Inc. open end ureteral catheter 5FR for the purpose of measuring exact ureteral length. Measurement results will be compared to measurements performed on CT scan (obtained before surgery).
