There are few reports on abdominal compartment syndrome that are caused by ovarian hyperstimulation syndrome (OHSS). Here, a case of a 29 year old woman is reported in which intravesical pressure measurement was useful in the management of severe OHSS that had been complicated by abdominal compartment syndrome. The patient's urinary output and general condition did not improve after the initial treatment. The woman's intra-abdominal pressure was evaluated indirectly, based on her intravesical pressure, and was found to be significantly elevated. The patient's urinary volume increased after a 14 mm Hg decrease in the intravesical pressure was achieved by the drainage of ascitic fluid. Intravesical pressure measurement was useful in the management of the general condition of this patient with OHSS.
