Imaging of the brain with CT and MRI is essential in patients with suspected idiopathic intracranial hypertension, to exclude elevated CSF pressure due to other causes such as brain tumor, dural sinus thrombosis, hydrocephalus, etc. Midlothian's Lawfield Primary School and South Lodge Primary School in the Highlands were also in the bottom five. See When and Why to Apply Heat to an Arthritic Joint and 9 Easy Ways to Apply Heat to an Arthritic Joint The treatment for oliguria should be continued keeping in view the guidelines of AKI treatment. All nephrotoxic drugs should be discontinued, and drugs excreted by the renal system should be carefully reviewed, and their doses should be adjusted. [3]Drugs metabolized by kidneys should be avoided. These drugs include doxorubicin, allopurinol, aminoglycosides, azathioprine, cephalosporins, clofibrate, digoxin, diazepam, meperidine, procainamide, propoxyphene, propranolol, and sulfonamides. In case these drugs are necessary, a dose modification must be done in accordance with the degree of renal injury. [1]

Oliguric patients are at higher risk of developing acute renal failure (ARF). 30 to 70 percent of patients with ARF develop infections that are associated with higher morbidity and mortality. [1] However, the mortality risk due to oliguria is not completely attributable to the development of ARF. [4]

Venous sinus stenosis is increasingly recognized as an important factor although whether it is the primary inciting abnormality or a potentiating factor remains to be fully established. The increasingly established clinical efficacy of venous stenting suggests that it is, however, not merely a biomarker 31. It has also been shown that the pressure within the torcula or the dural venous sinues and the opening pressure measured at lumbar puncture are very closely correlated 31. Radiographic features CT/MRI Patients usually present with headaches, visual problems (transient or gradual visual loss), pulse-synchronous tinnitus, photopsia, and/or eye pain 15,31. Less commonly IIH can also be encountered in males, usually older and less likely to be obese 15. It is rare in the pediatric population, being more common in the 12-17 year age group than in the 2-12 year age group 15,29. Associations It is due to the fact that the resorptive abilities of the kidney remain normal in prerenal causes. Urinary sediments can also aid in differentiating the prerenal and renal causes of oliguria. Urine samples from patients with prerenal failure often have hyaline and fine-granular casts, whereas brown granular casts with tubular epithelial cells are seen in patients with renal causes. [1]
