Use of POCUS and STONE Criteria Together in the Diagnosis of Nephrolithiasis

Patients presenting to the emergency department with symptoms suggestive of renal colic will be included in the study at Kocaeli City Hospital's emergency department. Patients with nephrolithiasis considered among the preliminary diagnoses will be enrolled in the study; demographic data, vital signs, and physical examination findings will be recorded on pre-prepared standard data forms. STONE criteria scores will be calculated by emergency assistants, and bedside ultrasound will be performed for patients. Ultrasonographic findings suggestive of renal colic, such as hydronephrosis, the presence of primary stones, acoustic shadowing of the stone, the presence of twinkle artifact, presence of jet flow, and presence of bladder debris, will be evaluated, and the obtained data will be recorded on the standard data form by the performing assistant physician. In patients where computed tomography, which is the gold standard for detecting stone presence without intervention, is deemed appropriate without any intervention to the primary examining physician, the computed tomography results and ultrasound findings will be compared. The study aims to evaluate the effectiveness of bedside ultrasound application in diagnosing stone presence in patients, its success in predicting re-admission to the hospital within 1 month, its success in predicting possible alternative diagnoses and complications, in addition to the stone criteria applied in the patients.
