“…According to Hamimi, the CT-Scan urography examination was carried out starting from patient preparation, patient positioning to the examination technique. The examination technique is carried out with the patient prone on a table with the feet first position of the body MSP parallel to the longitudinal light, the patient's MCP is located in the middle of the horizontal light from the gantry and the patient's arm is above the head [32]. CT examination of the urinary tract is shown in axial, sagittal and coronal sections [33].…”

“…In addition, it can be added with tea to speed up the diuresis process. MSCT is a diagnostic imaging method that can display cross-sectional anatomy in the axial, sagittal and coronal areas by visualizing urinary tract anatomy and stone pathology supported by ureteral tracking techniques without contrast media [32,37]. According to Yudha, to get optimal CT urography image results, positive or negative media contrast can be used.…”

The use of contrast media on CT scans needs to be done to see the urinary tract clearly. Contrast media itself has side effects that can harm patients if they have allergies. The purpose of this study was to determine if black tea can be used as a natural contrast medium to replace iodine contrast media in CT urography. This study used a case study method by observing a patient diagnosed with hydronephrosis who underwent CT urography. Prior to the examination, the patient had drunk 600 ml of black tea. Examination using CT Scan GE Revolution ACT 32 slices with axial, coronal and sagittal images. The results of the image are then taken to a radiologist and a radiographer to assess the image quality and anatomical clarity in the form of an interview. The results showed that the patient drank 600 ml of plain black tea on a CT-Scan urography examination in cases of Hydronephrosis could open or clarify the ureteral tract, making it easier for doctors to read out radiographs. The use of tea was able to reveal the ureteral groove and facilitate tracking. Black tea with natural ingredients has the opportunity to be a substitute for iodine contrast media which uses chemicals in CT Urography so as to reduce the potential for allergies and side effects to patients and is inexpensive. Studies related to the ratio of black tea and water can be carried out to obtain an optimal density value.

“…One of the sites at our institution extensively adopted the LDCT in 2012, to meet the urologists needs for imaging after Extracorporal Shockwave Lithotripsy (ESWL) as well as follow-up imaging of patients with nephro- and uro-lithiasis. With growing expertise and increasing diagnostic confidence, the comfort zone boundaries were broadened and the LDCT use was extended to diagnostics of acute flank pain and acute abdomen for several indications such as diverticulitis, appendicitis and renal calculi [22] in concurrence with Hamimi et al [31] who studied the efficiency of low-dose technique using an effective mAs of 50 (very similar to our LDCT protocol), in diagnosis of renal calculi and concluded that it was crucial in the management of renal stone disease in the acute setting. Both Lee et al [12] and Poletti et al [11] demonstrated the use of LDCT in acute abdominal pain diagnoses.…”

Background Our aim was to compare CT images from native, nephrographic and excretory phases using image quality criteria as well as the detection of positive pathological findings in CT Urography, to explore if the radiation burden to the younger group of patients or patients with negative outcomes can be reduced. Methods This is a retrospective study of 40 patients who underwent a CT Urography examination on a 192-slice dual source scanner. Image quality was assessed for four specific renal image criteria from the European guidelines, together with pathological assessment in three categories: renal, other abdominal, and incidental findings without clinical significance. Each phase was assessed individually by three radiologists with varying experience using a graded scale. Certainty scores were derived based on the graded assessments. Statistical analysis was performed using visual grading regression (VGR). The limit for significance was set at p = 0.05. Results For visual reproduction of the renal parenchyma and renal arteries, the image quality was judged better for the nephrogram phase ( p < 0.001), whereas renal pelvis/calyces and proximal ureters were better reproduced in the excretory phase compared to the native phase ( p < 0.001). Similarly, significantly higher certainty scores were obtained in the nephrogram phase for renal parenchyma and renal arteries, but in the excretory phase for renal pelvis/calyxes and proximal ureters. Assessment of pathology in the three categories showed no statistically significant differences between the three phases. Certainty scores for assessment of pathology, however, showed a significantly higher certainty for renal pathology when comparing the native phase to nephrogram and excretory phase and a significantly higher score for nephrographic phase but only for incidental findings. Conclusion Visualisation of renal anatomy was as expected with each post-contrast phase showing favourable scores compared to the native phase. No statistically significant differences in the assessment of pathology were found between the three phases. The low-dose CT (LDCT) seems to be sufficient in differentiating between normal and pathological examinations. To reduce the radiation burden in certain patient groups, the LDCT could be considered a suitable alternative as a first line imaging method. However, radiologists should be aware of its limitations.

“…Some types of imaging modalities commonly used in evaluating disorders of the urological system are Blass Nier Overzicht (BNO-IVP), Ultrasound (USG), and Multislice Computed Tomography (MSCT) (Lampignano & Kendrick, 2017). Multislice Computed Tomography is one modality that can evaluate disorders of the urological system well because it has high sensitivity and specificity in detecting kidney stones (Hamimi & El Azab, 2016).…”

The MSCT urography examination requires patient preparation, such as fasting and drinking water.In addition,some hospitals use water,furosemide to accelerate the increase in urine volume.However,Furosemide is a chemical diuretic that is feared to increase the workload of the kidneys. So a natural alternative is needed, namely black tea.This study aims to determine the effect of black tea as an alternative diuretic on the urography MSCT examination. This is quasi-experimental research conducted at RSUD by Dr. Soehadi Prijonegoro Sragen,Central Java. Respondents in this study consisted of 18 outpatients with an MSCT urography examination. These respondents were divided into three groups, namely the group of mineral water, furosemide,and black tea, and three radiology doctors. The scanning process uses MSCT 128 Slice and then tracks MSCT urography with the Curved Multiplanar Reconstruction (MPR) application.Data obtained from observations,questionnaires,and interviews with radiologists was then processed and analyzed using quantitative methods.Normal distributed data was analyzed using the ANOVA test. The results showed a significant difference from the assessment of kidney HU,liver HU, and ureteral dilatation in the mineral water, furosemide, and black tea test groups with sig values.<0.05.Black tea increases Hounsfield Unit (HU) values in the kidneys,lungs,liver,and ureteral dilation, as a tracking picture shown in the Curved Multiplanar Reconstruction(MPR) application. This confirms that black tea can be used as a natural diuretic alternative for some reasons:effective, fast, easy, and inexpensive.It makes it easier to track kidney stones.The operation of curved multiplanar reconstruction(MPR) applications during reconstruction can display more optimal image results to support more accurate diagnostic information.
