Abstract:
This study carried out namely in two hospitals: Fedail hospital and Ibn-Alhaytham Diagnostic Center, during the period from July 2012 to January 2013.
The objective of this study was to evaluate the accuracy of computerized tomography urography (CTU) in diagnoses pathology of hydronephrosis , minimize the radiation dose , examination cost , and time to reach the final diagnoses.
Siemens somatom sensation 16 slice helical CT scan apparatus was used. Abdomen routine protocol was performed with or without administration of amanopaque as contrast media.
A total of 63 patients their ages are (1-14 years) with hydronephrosis CTU detected the underlying pathology of hydronephrosis in 59 out of 63 (93.7%), and failed in 4 cases to detect it , although CTU detect the presence of hydronephrosis in these cases.
These cases include , one case of lower ureteric ligation during surgical operation, one case of urinary tract neoplasm , and two cases of chronic inflammatory of urinary tract.
CT has become superior modality for diagnosing the underlying pathology of hydronephrosis , and concluded to that CTU is the best protocol for demonstration the underlying pathology of hydronephrosis than other modalities as U/S and IVU.
