Stone_score_for_uncomplicated_ureteral_stone_guideline v.1
STONE Score for Uncomplicated Ureteral Stone predicts the likelihood of ureteral stone in nontoxic-appearing patients with flank pain.
To assist clinicians to risk-stratify patients in order to predict the likelihood of ureteral stone in nontoxic-appearing patients with flank pain.
Use in patients with suspected kidney stones and normal renal function. Variables and points: - Sex: M=2, F=0 - Duration of pain prior to presentation: >24 hours=0, 6-24 hours=1, <6 hours=3 - Race: black=0, Non-black=3 - Nausea and vomiting: None: 0, Nausea alone=1, Vomiting=2 - Hematuria on urine dipstick: Absent=0, Present=3 STONE Score 0-5= Low Risk group= 9.2% Risk of having ureteral stone= Diagnostic decisions should be based on the other diagnoses being considered. STONE Score 6-9= Moderate Risk group= 51.3% Risk of having ureteral stone= Ultrasound performed after hydration and demonstrating hydronephrosis would increase the likelihood that this patient's symptoms are being caused by a kidney stone, and may decrease the patient's cumulative radiation exposure. STONE Score 10-13= High Risk group= 88.6% Risk of having ureteral stone= If clinically improving and low concern for alternative pathology, this patient could initially be managed conservatively without a CT scan. Low-dose CT would be appropriate if stone localization is needed. Note: Within each group, higher score indicates higher likelihood of a stone.
Not use in patients with fever or other signs of infection, recent trauma or urologic surgery, or active malignancy.
