Analysis of Non-Contrast CT Urography Image Information Using Watermelon Juice as a Diuretic Agent

This research aims to determine the difference in image results between giving watermelon juice and water as a natural diuretic in producing good image performance. The method used in this research was a true experiment with a posttest-only control group design. There are two groups determined through randomization by taking cards that have been numbered according to arrival. Odd card numbers in the control group were given water, and even card numbers in the treatment group were given watermelon juice; scanning was carried out after 60 minutes. Assessment of distension using measuring distance software, enhancement by measuring the Region of Interest and assessment of artefacts and anatomical information using a questionnaire. Data processing and analysis uses the Mann-Whitney test. The research showed that using watermelon juice as a diuretic in non-contrast CT urography examinations increased distension of the pelvic pelvis and bladder. In contrast, in the ureters, it did not. The p-value of distension of the pelvic rents was 0.003, ureter 0.345 and bladder 0.036. It does not cause enhancement in the pelvis, ureters and bladder; the p-value of the pelvis is 0.599, the ureter is 0.294, and the bladder is 0.345. It does not cause artefacts in the pelvis, ureters and bladder. The p-value of the pelvis is 1.000, the ureter is 0.680, and the bladder is 0.511. Moreover, produces the same anatomical information; the p-value is 1,000. This study concludes watermelon juice as a natural diuretic provides superior imaging performance in pelvic and bladder distension compared to water.
