Background: Urinary tract stone is increasing dramatically in recent years so is the diagnosticrncapability especially after the employment of abdominopelvic CT. The wide use of rnabdominopelvic CT in the diagnosis, treatment planning, and follow-up of these patients raisedrnthe issue of radiation exposure. For this reason, CT protocols that decrease the radiation dosernwithout decreasing the sensitivity and specificity of depicting stone have been implemented. Therncommon of these protocols is low dose CT despite its wide advocation there is wide variation inrnCT protocols in different institutions. The CT protocol used in our country is not known and therernis no national guideline or recommendation for these types of patients, therefore, a wide variety ofrnprotocols in different institutions is expected of which some may expose patients to unnecessaryrnradiation. rnObjectives: To study the amount of radiation dose patients at tikuranbessa specialized hospitalrnpatients with urinary tract stone disease receive in being evaluated by abdomen/pelvic CT rnMethods: a retrospective cross-sectional was done February 1to august 31, 2021, at TASH inrnpatients who had their scan for urolithiasis or symptoms related to urolithiasis 1/07/202031/10/2020rnG.Crnarernincludedrnuntilrnthernsamplernsizernisrnattained.rnDatarnwererncollectedrnbyrnthernprincipalrnrninvestigator with a structured questioner that evaluates the number of CT they had The CTrncharacteristics like DLP CTDvol, date, and place the CT was taken.
