Glucagon and ureteric calculi.

Glucagon may act as a relaxant of smooth muscle and it has been suggested that this action may assist in the passage of ureteric calculi and diminish ureteric colic. These effects may be of clinical use to avoid inpatient admission to hospital for the symptomatic relief of ureteric colic. Ten successive patients with acute ureteric colic were given 1 mg of glucagon and two litres of fluid administered by the intravenous route and analgesia as required over three hours. Progress was monitored radiologically and clinically. In no case did significant progression or passage of stones occur and seven patients required parenteral analgesia. We conclude that glucagon is not effective for the management of ureteric colic in a casualty department.
