Abstract
PURPOSE: We evaluated whether cessation of renal colic is consistent with an expelled ureteral stone or whether imaging may be indicated even in the absence of symptoms. MATERIALS AND METHODS: We performed a retrospective study of patients who presented to our institution with acute renal colic and ureteral stone, and were subsequently evaluated at a followup visit where they reported complete cessation of pain for at least 72 hours. RESULTS: Study inclusion criteria were met by 52 patients, who reported no pain for at least 72 hours at the time of the followup visit. A persistent ureteral stone was demonstrated in 14 of the 52 patients (26%) although they denied any associated symptoms. Multivariate logistic regression did not show an association between stone size or location and the likelihood of passage in this cohort. CONCLUSIONS: Cessation of pain was associated with ureteral stone passage in almost 75% of this study cohort but 26% of patients still had persistent ureteral stones. We recommend routine followup imaging in all patients with ureteral stones to document stone passage and avoid the risks of silent ureteral obstruction.
