Doppler sonography in diagnosis of the acute scrotum.

Doppler sonography has been reported to be a reliable technique for diagnosing acute scrotum significantly decreasing the number of unnecessary surgeries. The aim of this paper was to demonstrate the superiority and validity of Doppler sonography over conventional sonography for differential diagnosis of the acute scrotum. In the period from 2002-2004, 300 patients underwent ultrasound examination of the testicles at the Institute of Radiology in Novi Sad.

[Diagnosis of ureteral calculi using ultrasonography, intravenous urography and unenhanced helical computed tomography].

Introduction: The pain in the loins is usually the consequence of renal colic caused by small ureteral calculi.

Ultrasonography: Ultrasonography is an efficient tool in the detection of calculi in the pyelocalyx system, but it may not be sufficient for the area of renal pelvis and ureter, as wll as for the ureter and the ureterovesical junction.

Intravenous Urography: Radiolucent stones, dilatation of the ureter and of the pyelocalyx system were identified on the urogram, which are common signs of ureter calculosis.

[Native and contrast radiographic examination of the urinary tract].

Introduction: Plain x-rays and contrast urography are important for diagnosing urinary tract diseases. The first plain film of the urinary tract was made in 1896, and the first tests using contrasts started in 1904. Excretory urography has been used since 1930.
