228 - Common site of ureteric calculi among Nepalese population.

Ureteric calculi are essentially a kidney calculus that has passed into the ureter. We aim to determine the common site of ureteric calculi using computed tomography (CT) scan. Patients referred to CT department for non-contrast CT scan of kidney, ureter and bladder (KUB) were scanned from July to September 2018 in 16 slices MX CT scanner, Philips Medical System. Patients identified with ureteric calculi and age ≥16 years were included in the study. The data were analyzed using SPSS statistics version 27.0. Chi Square test (x2) test was applied to determine the association between ureteric calculi and demographic variables. Binary logistic regression (BLR) analysis was performed. Hosmer and Lemeshow test were performed before BLR modelling. Multicollinearity was calculated for demographic variables by using Pearson's Chi-square test for independence. 76 patients, 58 male and 18 female, mean age 39.67‡15.69, range 18 to 82 were included in the study. Calculi were identified in both ureters, 53.9% in right ureter and 46.1% in left ureter respectively. 60.5% of calculi were noted at pelvic-ureteric junction (PUJ) and 39.5% at vesico-ureteric junction (VUJ). x2 test showed the location of ureteric calculi were independent of both gender and age groups, p>0.05. Both gender and age groups did not add significantly to the BLR model, p>0.05. Females were 2.63 times more likely to have VUJ calculi than males. Age groups <30 and 30-60 years were 3.52 and 2.15 times more likely to have VUJ calculi than >60 years age group. Ureteric calculi are a major health concern in Nepal and is most common in right PUJ. Adequate precaution and preventive measures should be adopted as soon as possible. [ABSTRACT FROM AUTHOR]
