Abrams L, Krambeck A, Valadon C, et al. - Researchers performed a retrospective analysis of 135 patients with acute renal colic because of nephroureterolithiasis managed by a single surgeon, to determine whether trial of passage (TOP) or initial surgical intervention led to less narcotic analgesia utilization in this patient population. Over the entire treatment course, rates of narcotic prescription were compared for patients opting TOP vs surgery [primary or delayed ureteroscopy]. According to the findings, narcotic prescriptions were more likely to be required for patients electing initial treatment with TOP for renal colic secondary to stone disease vs patients electing initial surgical intervention.
