Participants underwent face\u2010to\u2010face interview using a predesigned and standardised questionnaire. Details on demographic data, comorbidities, dietary variables and lifestyle were collected. Ultrasonographic examination of the kidney, ureter and bladder was performed followed by blood and urine sampling. Prevalence was defined as the proportion of participants with kidney stones, and univariate logistic regression was used to estimate the associated factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1087 participants (486 male, 601 female) completed the questionnaire. Ultrasonographic examination and laboratory investigation were carried out, with an overall response rate of 98.8%. The prevalence of ultrasonographic proven urolithiasis in the sample studied was 4.04%. The mean age of patients with urolithiasis was 50.05 (SD 14.6, range 18\u201389), and the male to female ratio was 1.2: 1. Univariate analysis showed that odd ratio of personal history of urolithiasis (0.16, p:0.00), salty food intake (0.39, p:0.02), family history of urolithiasis (0.39, p:0.01), and hypertension (1.77, p:0.04) was significantly associated with a greater risk of urolithiasis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The prevalence of urolithiasis in this study population is 4.04%. It affects males and females equally; 61.4% are in the age group of 25\u201364\u2009years. Hypertension, high salt diet, personal history of urolithiasis and family history of urolithiasis are significant risk factors.<\/jats:p><\/jats:sec>","DOI":"10.1002\/bco2.152","type":"journal-article","created":{"date-parts":[[2022,4,20]],"date-time":"2022-04-20T03:39:50Z","timestamp":1650425990000},"page":"74-80","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Prevalence of urolithiasis in Sarawak and associated risk factors: An ultrasonagraphy\u2010based cross\u2010sectional study"],"prefix":"10.1002","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0024-8797","authenticated-orcid":false,"given":"Kamal Raj","family":"Perumal","sequence":"first","affiliation":[{"name":"Department of Urology Sarawak General Hospital  Sarawak Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richelle Huey Bing","family":"Chua","sequence":"additional","affiliation":[{"name":"Department of Urology Sarawak General Hospital  Sarawak Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guan Chou","family":"Teh","sequence":"additional","affiliation":[{"name":"Department of Urology Sarawak General Hospital  Sarawak Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Clarence Chang Moh","family":"Lei","sequence":"additional","affiliation":[{"name":"Department of Urology Sarawak General Hospital  Sarawak Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,4,20]]},"reference":[{"issue":"3","key":"e_1_2_15_2_1","first-page":"S45","article-title":"Epidemiology of nephrolithiasis","volume":"13","author":"Ramello A","year":"2000","journal-title":"J Nephrol"},{"key":"e_1_2_15_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00240-005-0003-7"},{"key":"e_1_2_15_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/978\u20101\u20104615\u20102556\u20101_174"},{"key":"e_1_2_15_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/s0090-4295(01)01606-5"},{"issue":"3","key":"e_1_2_15_6_1","first-page":"142","article-title":"Incidence of urinary stones in the various states of mainland Malaysia","volume":"36","author":"Sreenevasan G","year":"1981","journal-title":"Med J Malaysia"},{"key":"e_1_2_15_7_1","doi-asserted-by":"publisher","DOI":"10.21315\/mjms2018.25.4.12"},{"key":"e_1_2_15_8_1","unstructured":"Malaysia \u2010 Country Profile \u2010 2020.
