Fig. 1.

Intrauterine tamponade balloons used in this study. The condom catheter is shown filled to 500 mL of fluid (with a urologic syringe cover blocking extrusion of fluid). Unlike the other balloons in this study, the condom catheter has no drainage tip. The latex and silicone Foley pictured here each contains 30 mL of fluid. The Sengstaken is shown with only the gastric balloon filled to 300 mL. The BT-Cath's drainage tip is flush with the end of the balloon; here it is filled to 500 mL of fluid. The Bakri balloon is also filled to 500 mL. The ebb is filled to 750 mL in the uterine balloon and 300 mL in the vaginal balloon. The ebb's drainage tip protrudes from the end of the balloon initially, but as the balloon fills, it no longer protrudes. The vaginal balloon can also slide superiorly toward the uterine balloon (not shown).
