Portis JL, et al. - Researchers assessed the National Institutes of Health’s Patient Reported Outcome Measurement Information System (PROMIS) pain instruments in patients with acute ureteral stones. Results demonstrated PROMIS pain scores to be independent of stone size and location. Potential to improve patient care was offered by attention to Emergency Department (ED) discharge symptom control. For patients with ureteral stones ≤1 cm, PROMIS pain intensity was an independent predictor of surgical intervention. Experts noted an association of pain scores associated with age, gender and ED pain scores. Stone size <4mm, proximal location predicted initial stone surgery but not pain interference. For stone size <4 mm, failure of attempted stone passage was less likely, and it was more likely for proximal stone location and pain intensity >60.
