Abstract : Urolithiasis is a situation where stones are found in urinary tracts. This disease is the third most common disease in the urinary system. The leading factors behind stone formation are including age, hormones, muscle mass, diet, body index, climate factors, fluid balance and urine PH. This study aims to discover the relationship between urine pH value and stone types in patients with urolithiasis. This study is an observational analytic study with a cross-sectional method using secondary data in the form of medical records from Urology department of Dr. Soetomo Regional Hospital 2019 - 2020. This study obtained 56 research samples, with the age group characteristics ranging from six - 76 years old. The average age was 49, 92 ± 12.91, on 43 men and 13 women. PH range that was most frequently found layes on pH 4.5 - 8.0. The average pH values were as follow: carbonate stones composition was 6.16, oxalate was 6.33, calcium was 7, phosphate was 6.38, ammonium was 6.33, while uric acid was 6.25.
