Abdominal compartment syndrome: urological aspects

ACS is prevalent in various surgical conditions and in a large percentage of critically ill patients. Measuring the IAP is important in the early diagnosis of ACS and can be easily done by measuring the intravesical pressure. ACS adversely affects many organ systems; the pathogenesis of renal dysfunction is probably multifactorial, from a combination of reduced cardiac output, reduced GFR mediated by secretion of renin and angiotensin, aldosterone-mediated water reabsorption, increased renal parenchymal pressure and direct compression of the renal vein. Successful treatment requires a high index of suspicion, prompt recognition and early surgical abdominal decompression.
