Treatment of Renal Colic Using Intracutaneous Injection of Sterile Water

Pain relief of acute renal colic is usually achieved by administration of narcotics because of its severity, which is comparable to labor pain. Although not asserted in the article, it seems that this trial had been performed on "acute" renal colic as the pain score had been between 8 to 10 before treatment according to visual analogue scale. The investigators had explained to the patients that they were receiving either sterile water or saline for their pain and they had consented to enter the trial. At the end of the trial, 63% of the control group had suffered from pain for as long as one and a half hours.
