STONE STUDIES
SILENT OBSTRUCTION
Retrspective study of 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. The authors conclude 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. (1)
RELATION TO ASTHMA
Large study of 20,906 people >20yrs (NHANES 2007–2014) found urinary stone formation in adults increases the odds of asthma by 26%. (2)
