Most documented cases can be classified into one of three types of renal lesions known to produce renal ischemia with subsequent development of hypertension, namely, renal artery stenosis (Goldblatt mechanism) [42], external renal compression (Page mechanism) [43], and intra-renal arteriovenous fistula [44]. In this study, none of these types of damage was founded in imaging evaluation of posttraumatic renal injuries. The diagnostic refinement derived
from the use of ambulatory blood-pressure monitoring allowed the identification of 29% of cases of arterial hypertension (9 patients). No previous study in the literature on renal trauma and arterial hypertension had used ambulatory blood pressure monitoring. Salubrinal chemical structure It is important to note the low average age Forskolin chemical structure of the hypertensive patients with future cardiovascular risks associated
with the high rate of familial arterial hypertension. There was no direct correlation between the grade of renal injury and the presence of arterial hypertension, although 66.7% of the cases had renal injury of grade III. Morphological evaluation by both computed tomography and magnetic resonance angiography excluded any possibility of renal artery stenosis, external renal compression or arteriovenous fistula. Furthermore, there was no correlation between a serious reduction of renal function found by DMSA renal scintigraphy and the presence of arterial hypertension. In the patients with renovascular hypertension, the dynamic renal scintigraphy with the use of the 99mTc EC demonstrates a gradual accumulation of the radionuclide in the kidney affected during the phase of the study after captopril administration. This can be explained by the reduced glomerular filtration rate,
measured scintigraphically as delayed uptake and cortical retention. this website Investigators have reported the test to have approximately 90% sensitivity and more than 95% specificity [31, 46]. The diagnosis of a rennin-dependent renovascular hypertension was excluded Progesterone in all patients, suggesting that arterial hypertension may be essential. Conclusions The present study showed that non-operative management of renal trauma, specifically in high grades, can be safe with low index of complications. The late functional outcome was favorable in patients with renal injuries of grades III and IV with extravasation, differing significantly from the worse functional outcome in those of grades IV and V with vascular injuries, suggesting that the degree of renovascular injury and the extent of nonperfusion of the kidney at admission CT scan appear to determine the functioning volume loss observed by abdominal CT scanning at the follow-up assessment.
