IntroductionRenal colic is a prevalent cause of abdominal pain in the emergency department. Although non-steroidal anti-inflammatory drugs and opioids are used for the treatment of renal colic, some adverse effects have been reported. Therefore, desmopressin -a synthetic analogue of vasopressin- has been proposed as another treatment choice. In the present study, indomethacin in combination with nasal desmopressin was compared with indomethacin alone in the management of renal colic.MethodsIncluded in the study were 124 patients with initial diagnosis of renal colic and randomized to receive indomethacin suppository (100 mg) with either desmopressin intranasal spray (4 puffs, total dose of 40 micrograms) and or placebo intranasal spray.ResultsAll the included patients were finally diagnosed with renal colic. There was no difference between the two groups in pain at the baseline (p = 0.4) and both treatments reduced pain successfully (p < 0.001). There was no significant difference between the two groups in pain reduction (p = 0.35).ConclusionsWhile there was significant pain reduction in both patients groups, pain reduction of NSAIDs (e.g. indomethacin) in renal colic, does not significantly improve when given in combination with desmopressin.Copyright © 2018 Elsevier Inc.
