[Role of color Doppler echography in the diagnosis of obstructive uropathy]. / Ruolo dell'ecocolor Doppler nella diagnostica delle uropatie ostruttive.

Intrarenal Doppler US was performed in 20 patients with suspected renal obstruction and standard sonographic appearance of collecting-system dilatation. In 15 patients with true renal obstruction the resistive index (I.R.) was > 0.7. The A.A. think duplex Doppler US is a valuable addition to the standard sonographic evaluation to increase the diagnostic accuracy in patients with suspected renal obstruction.

[Echographic features in the diagnosis of renal abscess]. / Aspetti ecografici nella diagnosi di ascesso renale.

The Authors emphasize sonographic aspects of Renal Abscess in early phase and in proclaimed disease. The advent of the sonography and its extensive use marked an inversion of tendency in Perinephric Abscess evolution. So it is possible to point out small Abscesses and in early phase. Leukocytes tags Scintiscan and CT can confirm the diagnostic tentative.

[Urethral echography: potential and limitations]. / L'ecografia uretrale: possibilità e limiti.

Since in the early years of 1980, the diagnostic for images about male's urethral injury was exclusively assigned to urethrocystography. Sially in repeated check the gonads too often are exposed to ionizing radiations. Our results show urethrocystography/ultrasonography good correlation (13/15) cases) with 86% sensibility. Even if the urethrocystography is a methodic of first instance, the urethral ultrasonography is efficacious in follow up of urethral injury, particularly in the study of anterior urethra.

[Echohysterography in the diagnosis of female sterility: preliminary results]. / L'ecoisterografia nella diagnostica della sterilità femminile: risultati preliminari.

Couple's study infertility sometimes need repeated hysterosalpingographical evaluations. In three cases the A.A. value echohysterosalpingography's utility. The echohysterosalpingography gives morphological and functional dates, is easy repeatable and the patients aren't exposed to ionizing radiations.

[Echographic characteristics of calcifying fibrous pseudotumor of the epididymis]. / Aspetti ecografici dello pseudotumore fibroso calcificante dell'epididimo.

Calcifying fibrous pseudotumor of epididymis is a rare neoplasia. The A.A. report echographical aspects about two clinical acses examined in 1993. Peculiar aspects of tumour are characterized by acoustic obstruction of the fibrous tissue and contextual iperechogenic spots, so to stimulate a calcific pseudocapsula. The A.A. revalue the echographical images after surgical exploration and discuss about differential diagnosis with TBC.
