Glucagon and diuresis in the treatment of ureteral calculi.

Intravenous glucagon and diuresis caused by diagnostic doses of sodium diatrizoate were used to treat 5 patients with ureteral colic and urographic findings consistent with partial obstruction by a ureteral calculus. Pain was relieved and the calculus passed within two hours in 4 patients and within eight hours in the fifth. No complications were noted.
