[Angiomyofibroblastoma in a male patient – a case report on a rare paratesticular lesion and review of the literature].

Összefoglaló. A scrotum képalkotó vizsgálóeljárásai közül elsőnek választandó az ultrahang, mivel könnyen hozzáférhető, szenzitivitása és specificitása magas. Szerepe kiemelendő mind az intratesticularis eltérések differenciáldiagnózisában, mind pedig a kevésbé ismert paratesticularis eltérések esetében.

Microcirculatory effects of sildenafil in experimental testicular torsion in rats.

Purpose: Investigate the short-term effect of sildenafil on microcirculation, especially the velocity, the pattern of the flow and the recruitment of the leukocyte in postcapillaries.

Methods: In male Sprague-Dawley rats, the microcirculatory consequences of 60 min experimental testicular torsion, followed by 240 min of reperfusion, were examined. Using fluorescence intravital microscopy, changes in red blood cell velocity in post-capillary venules and rolling as well as adhesion of leukocytes in the postcapillary venules were examined before the torsion and every hour during the reperfusion period.
