Evaluating Ureteral Length Using Computed Tomography (CT)
Evaluation of Ureteral Length Measurement by Computed Tomography (CT) to Actual Ureteral Length Measured by Ureteral Catheterization

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.

Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
  • Ureteral Calculi
  • Hydronephrosis
  • Ureteral Obstruction
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).

Other Names:
  • Cook Urological Inc. open end ureteral catheter 5FR
  • Karl Storz cystoscope 19-22F
Experimental: Ureteral catheterization

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).

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