Table 1 Classification of ascites used in our Unit

From: Outpatient management of severe early OHSS by administration of GnRH antagonist in the luteal phase: an observational cohort study

Grade Description
No ascites No presence of fluid
Low Small amount of fluid, barely detectable by ultrasound in the pouch of Douglas
Moderate Increased amount of fluid located in the small pelvis
Marked Large amount of fluid reaching the level of the umbilicus
Massive Significant accumulation of fluid reaching Morrison’s pouch
Tense Significant accumulation of fluid up to the level of the diaphragm with/without hydrothorax
  1. The classification of ascites used in our Unit is similar to previously published criteria [6, 29] and distinguishes different levels of ascites, depending on the accumulation of ascetic fluid when the patient was at the anti-trendelenburg position. This classification system is reproducible and more clear compared to the subjective description “clinical or ultrasound evidence of ascites” mentioned in previous OHSS classifications [4, 2628, 30].
