[Differential x-ray and ultrasound diagnosis in cavernous renal tuberculosis].

It is virtually very difficult to make a differential diagnosis of cavernous nephrotuberculosis and caliceopyeloectasia (CPE), as well as a combination of caverns and CPE at primary renal ultrasound scanning. Therefore, a complex of diagnostic methods for nephrotuberculosis should include drug echography with a diuretic. Comparing X-ray findings, ultrasound and drug echography with a diuretic allows one to differentiate cavernous nephrotuberculosis from CPE and their combinations with confidence.
