Abstract

Objective: To describe the imaging characteristics of high urinary tract stones in patients treated with computed tomography at Thai Binh University Medical Center. Subjects and methods: A retrospective, descriptive cross-sectional study was conducted on 136 patients. Results: Regarding the distribution of stones: The incidence of isolated kidney stones was 37.5%, isolated ureteral stones was 30.9%, and the incidence of coexisting kidney and ureteral stones was 31.6%. Characteristics of kidney stones: The S0 group of renal calyces predominated with 55.3% (n = 94); Within each renal unit, the proportion of S0 stones was 65.6%. Kidney stones in the S1 pelvis or S2 renal calyces/pelvis account for only 3.2% and 11.7%, respectively. Regarding quantity: The percentage of renal units with ≥ 3 stones on the right side is 40.7%, and on the left side is 42.2%; the percentage of renal units with 2 stones on the right and left sides is 20.3% and 14.0%, respectively. Regarding size: The majority of stones are < 20mm, accounting for 56.4%. Regarding stone density: 59.4% of kidney stones have a density < 950HU, and 40.6% have a density ≥ 950HU. Characteristics of ureteral stones: The upper third location accounted for the highest percentage at 58.3% (n = 96). In terms of number: a single stone accounted for the highest percentage (90.6%). In terms of ureteral stone size: The largest average size was 14.1 ± 7.4 mm; stones > 10 mm accounted for the highest percentage (63.5%), while stones between 6 and 10 mm accounted for 25.9%. In terms of density: 57.6% of cases had a density ≥ 1000 HU.
