Evaluating Ureteral Length Using Computed Tomography (CT)

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.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Patients undergoing planned procedure involving ureteroscopy or ureteral stenting
Abdominal CT scan performed within 6 months prior to intervention

Exclusion criteria

Known iodine sensitivity
Patients with fever or hemodynamic instability planned for urgent operation
Severe immune compromized patients
Severe thrombocytopenia < 50,000

Treatment and study plan

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).

Other names: Cook Urological Inc. open end ureteral catheter 5FR, Karl Storz cystoscope 19-22F

Primary outcomes

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

Time frame: 1 year
