Introduction: Ureteric colic (also known as renal colic) is a common reason for presentation to emergency departments (ED). Stone formation in the urinary tract affects about 5–10% of the population in industrialized countries and ureteric colic accounts for approximately 0.6% of total ED visits.
Objective: To compare the diagnostic accuracy of STONE score and CHOKAI score in predicting the probability of ureteral stones in patients presenting with flank pain by taking CT Scan as a gold standard in emergency department.
Study Settings: Emergency Department, Sindh Institute of Urology & Transplant (SIUT).
Duration: 17 Jan, 2019 to 16 July, 2019.
Study Design: This was a Cross Sectional study.
Subject and Methods: After including the patients in study, patients were divided in to two groups through lottery method. Patients in Group A were subjected to STONE score and patients in Group B were subjected to CHOKAI score. Patients having STONE score >8 were labeled as having ureteral stones. While for CHOKAI score, a score of >6 were used to label the ureteral stones. All the study patients underwent CT scanning for confirmation of diagnosis of ureteral stones.
RESULTS: As per findings on Chokai Score, 64 (18.23%) patients had ureteric stones. As per findings on stone score, 40 (11.36%) patients had ureteric stones. As per findings on CT Scan, 80 (22.79%) were dignosed for ureteric stones. As per diagnostic accuracy of chokai score, sensitivity was 44.44%, specificity was 48.57%, PPV was 18.23%, NPV was 77.21% and accuracy was 47.72%. As per diagnostic accuracy of stone score, sensitivity was 33.33%, specificity was 46.56%, PPV was 11.40%, NPV was 77.21% and accuracy was 44.30%.
CONLCUSION: As per our results, we have come to the conclusion that the use of the STONE clinical score validates patients as low, moderate, and high risk for ureteral stone.
