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.

Conditions

Ureteral Calculi; Hydronephrosis; Ureteral Obstruction

Outcome Measures

Primary Outcomes (1)

• Agreement between measurement of ureteral length (Centimeters) measured by CT and by ureteral catheterization

  1 year

Study Arms (1)

Ureteral catheterization

EXPERIMENTAL

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).

Device: Ureteral catheterization - Cook Urological Inc. open end ureteral catheter 5FR

Interventions

Ureteral catheterization - Cook Urological Inc. open end ureteral catheter 5FR DEVICE

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).
