ABSTRACT
Introduction Although there is a rising interest on intra-abdominal hypertension (IAH) and abdominal
compartment syndrome (ACS) in the literature, there is still controversy about the ideal method for measuring IAP.1 Direct IAP measurement is not always possible and over the years the indirect IAP estimation via the bladder evolved as the gold standard, however, considerable variability in the measurement technique has been noted, not only between individuals but also between institutions.
