[Treatment of ureteral colic with glycerol trinitrate]
1Urologische Klinik, Klinikum Grosshadern, Universität München.
Method:
In an open randomized clinical trial, the efficacy of 2.4 mg glycerol trinitrate (GTN) administered in a variety of forms (2 x 1.2 mg capsules; 6 x 0.4 mg puffs of an atomizer; 2.4 ml of an 0.1% infusion solution) in comparison with 20 mg of butylscopolamine bromide i.v. (BSB) in 80 patients suffering from acute ureteral colic.
Results:
Some 30 minutes following medication, the effect was adjudged by the physician to be good (no pain) moderate (some pain still present) or non-existent (alternative treatment within 30 minutes).
Conclusion:
GTN was effective in 40% of the cases, BSB in 26.3%. A moderate effect was seen in 46.7% and 62.3%, respectively, while no response was elicited in 13.3 and 10.5%, respectively. In addition, recurrence within 24 hours, blood pressure, pulse rate and laboratory tests were recorded. Side effects occurred in 13 patients (12 in the GTN and 1 in the BSB group), but, with one exception (GTN i.v.), were all mild in nature.
