Including patients aged between 18-65 years that consulted with the ED
with complaints of flank pain due to renal colic, the present study is a
prospective randomized clinical study. The study was conducted between
January 1, 2019 - January 1, 2020. The study was approved by the
university’s ethics committee. The study is registered at
clinicaltrials.gov (NCT04209439). Written informed consent was obtained
from all of the study patients. The study was conducted in accordance
with the CONSORT guideline and the Declaration of Helsinki.
This pilot clinical feasibility study was conducted under the
definitions and protocols described in a published tutorial in a pilot
