ABSTRACT

Background: CT scan of kidneys, ureter and bladder is a specialized procedure in radiology used to assess the urinary tract for condition like calculi, infections, tumors, obstruction and structural abnormalities. We can also use USG for the diagnosis but for our concern USG can only detect larger stones and hydronephrosis, may fail to detect smaller stones or radiolucent ones.

Objectives: Our main objectives to discuss will be: to analyze the gender-based distribution of urinary tract calculi, to map the positional distribution of urinary tract calculi, to determine the presence of urinary tract calculi across different age groups.

Methodology: We have taken total of 160 patients of CT KUB both males and females of all age group, out of which 45 showed us the normal findings and 115 shows us abnormal findings. For age-wise distribution, patients were divided into six groups: 10–20 years (12 patients), 21–30 years (24 patients), 31–40 years (33 patients), 41–50 years (27 patients), 51–60 years (13 patients), and 61–70 years (5 patients). The age group of 31 to 40 years old had the highest incidence of calculi, suggesting that middle aged people are more likely to have urolithiasis.

Result: A total of 160 patients underwent non-contrast computed tomography of kidneys, ureters and bladder CT KUB for suspected urinary tract calculi. Out of these 115 patients (71.9%) demonstrated evidence of calculi on imaging, while 45 patients (28.1%) had normal scans with no detectable stones.

Discussion: The high detection rate of urolithiasis in this study reinforces the diagnostic superiority of non-contrast CT KUB, which effectively overcomes limitations of USG such as operator dependency and reduced sensitivity for small or radiolucent stones.

Conclusion: The observed demographic and anatomical pattern emphasize the need for targeted preventive strategies such as hydration and dietary modification in young males prone to calcium oxalate stones and urinary alkalization or metabolic assessment in older females at risk for uric acid stones.
