Role of Ultrasound in Evaluating Obstructure Uropathy in Sudanese

Abstract

The objective of this study is detection of urinary tract (UT) obstruction abnormality in the Sudan in 2015 and compare them with the previous studies . This study depends on practical scanning the through which the data was collected in a configuration of data collection sheet the data was collected from October 2015 to December the main results of this study are : Ultrasound examination can very quickly , demonstrate hydronephrosis . Regarding the types of hydronephrosis , ultrasound examination can easily determine deferent types . This study (100) patients came to ultrasound department check up . This result (65) patients (65% ) obstruction uropathy the causes of obstruction. Main cause stones 75% came next mass 20% , least infection 5% .Types Mild hydronephrosis 29% and Moderate hydronephrosis58% , severe hydronephrosis 13%. Ultrasound is sensitive and specific for renal stones , 83% and 100% for hydronephrosis , 83% and 100% , respectively . Its sensitivity to pick ureteric stones (40%) and to identify Hydroureter (50%) is low. Addition of Computer tomography (CT) KUB abdomen increases the sensitivity for ureteric stones to 100%. which results from obstruction . Ultrasound criteria of obstruction is hydronephrosis dilatation of the calyx ultrasound have high accuracy in detected fluid which results from obstruction the common causes of obstruction uropathy are stones and masses . prostrate enlargement and posterior urethral valve infant , infections . Ultrasound is non invasive portable no need for contrast media
