[Informative value of radiodiagnosis methods of pyelo-ureteral strictures in kidney anomaly].
A total of 98 patients aged 18-67 years (mean age 42.5 +/- 10.3 years) suspected to have a pelviureteral stricture (PUS) were examined using ultrasound investigation in B-mode (BUI), excretory urography (EU), angiography, slice and multislice computed tomography (SCT, MSCT). This combined examination allowed to make diagnosis of hydronephrosis in 83 (84.7%) patients including PUS diagnosis in 48 (57.8%) patients. Basing on CT findings PUS was operated in 41 (85.4%) patients. Sensitivity, specificity and accuracy of BUI in detection of the level of the upper urinary tract obstruction was 92.8, 75.0, 89.3%, EU--94.5, 77.8, 92.2, SCT--100, 97, 98.1%, respectively. MSCT detected the level of the obstruction in all the cases. PUS was identified by BUI in 26.5, 89.3, 65.6, EU--in 81.3, 73.7, 79.1, by SCT in 90.5, 96.8, 94.2, MSCT--96.3, 100, 97.8% cases. Thus, MSCT is most effective in radiodiagnosis of PUS and can be recommended as a method of choice in PUS.
