the presence of hemoglobin in urine. It usually is a result of the intravascular decomposition of red blood cells following the transfusion of incompatible blood, the effect of some chemical and biological poisons and drugs that cannot be tolerated or of any of several causative agents of infections, extensive injuries, and so on.

Repeat DUS and CT examinations were performed at 6, 12, and 24 months postoperatively, and the results revealed patent blood flow of the LRV (peak velocity 16 cm/s, 18 cm/s, and 18.5 cm/s, respectively, measured in the hilum portion, peak velocity within the stent was not measured as the effect of stent on ultrasound; [Figure 1]d) and stable position of the extravascular stent with no migration or erosion [Figure 1]e and [Figure 1]f.
Lung ultrasound can detect extravascular lung water (EVLW), fluid present in lung interstitium, which is strongly dependent on the left ventricle filling pressure [2].
Importantly, transfusion did not induce a significant effect on extravascular thermal volume index, which is a surrogate for extravascular lung water (30).
Vasogenic edema, the most common type of cerebral edema, is secondary to the movement of albumin, other plasma proteins, and fluid from the intravascular space into the extravascular space.
In contrast, the distribution of Gd-DOTA in DCE-MRI is determined not only by microvessel density but also by vessel permeability and size of the extravascular extracellular space.

The interstitium of kidney consists of extravascular spaces of renal parenchyma, bounded on all sides by vascular and tubular basement membranes.5 The renal interstitium is involved in all functions of kidney and affects the GFR, growth and differentiation of parenchymal cells; therefore any changes in the interstitium points towards the renal disease.6 The destruction of renal tubules and interstitial capillaries with accumulation of extracellular matrix proteins results in interstitial fibrosis.7
