[Use of sodium diclofenac in acute renal colic]

31 patients with symptoms of acute renal colic were treated with diclofenac natrium. According to preliminary results this drug is more effective for relieving pain of acute renal colic than the traditional combination of spasmolytics and analgetics. This might be due to the blocking effect of diclofenac natrium on the renal PG synthesis and release, thus decreasing the diuresis. Side effects were minimal, as nausea, vomiting etc. Authors highly recommend this drug as the first choice of treatment in acute renal colic.
