Kidney stone disease is one of the most frequent urinary system disorders, ranking third following urinary tract infection and prostate disease in urology departments, and is the most frequent by 10-15%. Objective: To detect urolithiasis in individuals with flank discomfort and renal colic using non-contrast computed tomography. Methods: A cross-sectional study was conducted at Chattha Hospital, Gondal Hospital, and Al-Amin diagnostic center. Prior to the non-contrast computed tomography KUB examination, a formal informed consent form was signed by each patient. In this study, a total of 126 individuals were examined, and all of them were diagnosed with urolithiasis and their incidental findings are evaluated on non-contrast computed tomography KUB. The average patient age was 44.2. For data analysis, the Statistical Package for the Social Sciences version 26.0 was used. The eligibility of patients remained determined using inclusion criteria. Results: According to the results of 126 urolithiasis patients, n = 71 (56.3%) were males, n = 55 (43.7%) were women, and the greatest ratio was n = 23, (18.3%) in the 51-60 year age group. The most prevalent clinical symptom of urolithiasis was renal colic n=74(35.1%).The right side (45.24%) was more affected than the left side (34.13%). The right renal pelvis (18.2%), has the highest percentage, and right vesico-ureter junction and left upper pole calyces (3.3%) has the lowest percentage. Patients having 1 stone has highest frequency (58.7%). since most of patients developed mild (8.7%) or moderate (16.7%) or severe (11.9%) of Hydronephrosis and mostly (74.6%) negative Hydro-ureter. Conclusions: In the research, males and patients aged 51–60 were more likely than females to have urolithiasis. The right side were more related to the NCCT KUB findings.
