The Predictive Value of Ureteral Jet Assessment With Ultrasound in Patients Presenting With Acute Renal Colic

This is a single institution, prospective study to evaluate the prognostic significance of renal and bladder ultrasound with ureteral jet assessment and its utility to evaluate the spontaneous stone passage rate of ureteral stones.

Inclusion criteria

  • age 18 and older at the time of consent
  • willing and able to sign consent
  • CT diagnosis of ureteral stone with a stone burden less than or equal to 10mm

  • obstructed solitary kidney
  • obstructed transplant kidney
  • bilateral obstructed kidneys
  • any condition or reason that, in the opinion of the treating physician, interferes with the patient's ability to participate or places the patient at undue risk.

Treatment and study plan

renal and bladder ultrasound with ureteral jet assessment

Device

The number of jets from each ureteral orifice will be tabulated over time so that ureteral jet frequency, defined as number of jets per minute, can be calculated. Patients will be categorized into three groups. Group I- no ureteral jets on the symptomatic side; Group II- continuous low-level ureteral jet on the symptomatic side; Group III- ureteral jets similar to nonsymptomatic side.

Primary outcomes

  1. Time in Days From Diagnosis to Stone Passage.

    Time frame: 42 days

    Number of days that have elapsed from date of diagnosis to date of stone passage or intervention to maximum observation time (42 days).

Secondary outcomes

  1. The Number of Cases With Concordant Treatment Recommendations Based on the Ultrasound and CT Scan.

    Time frame: 42 days
