The research about effect of urine volume to urine sediment examination in patient with Urinary Tract Infection (UTI) at Wahidin Sudirohusodo hospital was performed. This research aimed to find out the volume urine effect to urine sediment examination in Urinary Tract Infection (UTI) so as to improve the diagnostic a laboratory. This research used laboratorial eksperimental method with total samples are 30 consist of 13 male (43,3%) and 17 female (56,7%). Microscopically sample examination used Shih-Yung method with during urine with comparative volume 12 ml, 10 ml, and 8 ml. This research showed mean total urine sediment in volume 12 ml (leukocyte 37,75/μL; erythrocyte 7,77/μL; epithelial cells 7,96/lfv; bacteria 5,15/lfv) in volume 10 ml (leukocyte 22,67/ μL; erythrocyte 4,48/ μL; epithelial cells 4,35/lfv; bacteri 3,88/lfv) in volume 8 ml (leukocyte 12,20/μL; erythrocyte 2,16/μL; epithelial cells 2,50/lfv; bacteria 2,08/lfv) from One Way Anova statistic test get P value = 0,000 (<0,05) showed there is significant different between urine sediment used volume 12 ml, 10 ml, and 8 ml. From the result can be concluded that there is an effect of urine volume to urine sediment test in patient with UTI and volume 10 ml as smallest urine volume can give an accurate result.
