Abstract

Examination MSCT Scan Urography patients are positioned prone to diagnose stones in UVJ that enter the vesica urinary. The Planar Reformation Curve is used to show the overall widened ureter, tumor assessment in intraluminal and extraluminal and stone detection, whereas in RSUD Banyumas examination of MSCT Scan Urografi for kidney stone cases the patient is positioned prone and reformed using Curve Planar Reformation. The purpose of this research is to know the procedure of examination of MSCT Scan Urografi with kidney stone case, knowing the reason to do prone position, knowing the reason of use Curve Planar Reformation.The type of this research is qualitative research with case study approach. The data were collected by observation, documentation, interview to radiologist, sending doctor, radiographer and patient. The data obtained were processed using interactive analysis model with 4 stages: firstly by data collection, both data were reduced , then the presentation of data, and can be deduced.The results stated that the examination procedure of MSCT Scan Urografi with kidney stone case in RSUD Banyumas fasting patient from 10 pm and patient drinking mineral water 1500 ml until patient feel to urinate. Scanogram AP, scanning from procesus xypoideus to sympisis pubis with 5 mm slice thickness. Exposure factor 120 kV and 125 mAs. Reconstruction of coronal pieces with 8 mm slice thickness and reformed using Curve Planar Reformation with 2 mm slice thickness and 3 mm intervals. The position of prone aims to smooth the flow of urine from the kidneys to the vesica urinaria but, for kidney stones no effect when positioned prone, prone also at risk for the patient because it causes urine reflux from vesika urinaria to ureter and patient feel uncomfortable. The use of the Planar Reformation Curve aims to reveal a complete urinary tract in a single image, however, the Curve Planar Reformation requires adaptation, precision, and operator-specific expertise.
