Evaluating Ureteral Length Using Computed Tomography (CT)

Not Applicable

Completed

• Conditions: Hydronephrosis; Ureteral Calculi; Ureteral Obstruction
• Interventions: Device: Ureteral catheterization - Cook Urological Inc. open end ureteral catheter 5FR

• Registration Number: NCT01542593
• Lead Sponsor: Carmel Medical Center

Brief 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.

Arm && Interventions

Group	Intervention	Description
Ureteral catheterization	Ureteral catheterization - Cook Urological Inc. open end ureteral catheter 5FR	During a planned procedure involving ureteroscopy or ureteral stenting, ureteral catheterization will be performed for the purpose of measuring exact ureteral length. Measurement results will be compared to measurements performed on CT scan (obtained before surgery).
