Benefits of Steeping Black Tea as a Negative Contrast Medium on Ct Urography Examination

Abstract

The use of water as a contrast medium requires large amounts of water to fill the lumen of the Urinary Tractus and more water is reabsorbed by the body than is secreted into urine. Steeping Black tea contains Caffeine which is able to increase blood flow in the kidneys thus inhibiting the process of absorption of Na, Ca and Mg causing stimulation of the kidneys to increase the amount of urine production. The purpose of this study is to prove that drinking black tea can increase urine production as a negative contrast medium to see differences in the distension and density of the Urinary Tract on CT Urography examination. This type of research uses True Experimental with Pretest-Posttest Control Group Design research design. Patients selected by Simple Random Sampling. Analysis: Paired t test and Independent t test. The results of the study of the use of 600 ml steeping Black Tea as a negative contrast medium on CT Urography examination did not show the difference in mean difference between the left renal Pelvis p value 0.956, Left UVJ 0.640, Right UVJ 0.935 while on the right renal Pelvis p value 0.001 showed differences in mean difference between the left renal Pelvis p value 0.956, Left UVJ 0.640, Right UVJ 0.935 while on the right renal Pelvis p value 0.001 intervention and control group. Hasil pengukuran p value densitas Vesika urinaria sebesar 0,678. Conclusion: Black tea can be used as a negative contrast medium on CT Urographic examination but when compared with mineral water it does not show a significant difference.

The Effect of Using Black Tea as an Alternative Diuretic on Multislice Computed Tomography (MSCT) Urography Examination

“…The black tea test group in this study experienced wider ureteral dilatation (seen from the diameter of the ureter) than other groups. According to Yudha et al (2020), if the ureter is dilated or there is urine in the lumen of the ureter during the MSCT examination, it will clarify the image results and facilitate the assessment of overall urinary tract abnormalities. The density value of the urinary tract as a whole will decrease along with the large amount of urine produced by the kidneys that fill the lumen of the ureter to the urinary vesicles.…”

“…The density value of the urinary tract as a whole will decrease along with the large amount of urine produced by the kidneys that fill the lumen of the ureter to the urinary vesicles. This causes differences in the density of surrounding organs so doctors can assess and diagnose abnormalities that arise in the urinary tract (Fa'ik, 2018;Yudha et al, 2020).…”

“…Examining MSCT urography requires patient preparation, such as fasting and drinking plenty of water to increase urine production. An increase in the volume of urine excreted by the kidneys is expected to meet the lumen of the urinary tract so that anatomical structures can be visualized and abnormalities can be assessed (Yudha et al, 2020). Using MSCT, evidence was found that water becomes a negative contrast medium that effectively produces image clarity and organ distension (Makarawo et al, 2013;Sulaksono et al, 2016).…”

“…Tea contains minerals such as calcium, magnesium, manganese, flavonoids, zinc, ferrum, potassium, and caffeine (Klepacka et al, 2021). The caffeine content in black tea causes an increase in blood flow to the kidneys by preventing the absorption of sodium, calcium, and magnesium, which stimulates urine production by the kidneys (Yudha et al, 2020). In the MSCT urography examination, a more detailed picture is essential to see the anatomy of the urinary system.…”

An Innovation of Black Tea as a Substitute for the Use of Positive Contrast Media in CT Urography in Hydronephrosis Cases: Case Study

“…The use of black tea on examination can affect urine production to increase so that it can affect the value of its density. Any change in the density value in an organ will help in evaluating abnormalities in the urinary tract because of the difference in the HU value between the stone and the surrounding tissue [38]. However, the CT scan analysis differs from the HU evaluation in that there is insufficient information in the characterization and composition of kidney stones due to the large variability in different brand scanners [39].…”
